The floodplain along the lower one-third has been converted from riparian forest and prairie to agriculture. The changes in basin and floodplain physiography and channel morphology have reduced commercial fish harvest by more than 80% and are implicated in the demise of native species. In some instances nonnative fish have replaced endemic species in the mainstream reservoirs, where breeding and maturing habitat for riverine species has been eliminated. Suggested solutions include a holistic approach to future research and management.Conference International Large River Symp. (LARS), Honey Harbour, Ont.

Within the upper unchannelized section, 96.2% of the larvae were collected in the discharge of two tributaries, which lie in the lower one-third of the reach. Survival from larval to young-of-the-year stage (June through August) was highest during 1991 due, in part, to the recent drought. Reduced fluctuation of river stages occurred as a result of reduced runoff, which minimized the need to reduce discharge to prevent flooding in the lower basin. The mean weight of paddlefish captured during the 1991 snagging season increased from 6.89 kg in 1990 to 7.45 kg, while the mean length increased from 739 mm (eye-to-fork length) to 753 mm. The percentage of snagged paddlefish 10 years old or older decreased from 15.3% in 1990 to 9.5% in 1991.1`Z1993 Issn 0077-6351 English Journal Article ASFA 1: Biological Sciences & Living Resources2CNZg'tpz%%**;068;.>DE ,&Mesiar, D.C.

These rivers share characteristics (e.g., extensive multi-channel river mouths, turbid water, debris, large physical river dimensions, and presence of several fish species with overlapping spatial and temporal distributions) which make collection of such information difficult. Sonar was identified as a potential solution to the problem, and techniques of application and analysis were developed in the Yukon River between 1982 and 1985. Four primary components of the application are: identifying an appropriate site for equipment installation; identifying and ensonifying all areas of fish passage; expanding fish passage rates to temporal and spatial strata; and apportioning fish-passage estimates to species. 6 B 0*Conference Int.

Shortnose sturgeons used two freshwater reaches and one saline reach annually. Sexually mature fish began moving upriver from freshwater wintering areas to a spawning site in April, when increasing river temperature reached about 7 oC and decreasing river discharge reached about 570 m3/s. Following spawning in late April-early May, fish moved downriver either to a freshwater reach where they remained all year or farther downriver to a saline reach where they remained for up to 6 weeks. After fish used the saline reach, they returned upriver to fresh water. Atlantic sturgeons entered the river from coastal waters by mid-late May, when increasing river temperatures reached 14.8-19.0 oC and decreasing river discharge reached 303-675 m3/s, occupying a saline reach with 0.0-27.5% salinity. After using the same saline reach visited briefly in spring by shortnose sturgeons, Atlantic sturgeons emigrated from the river by October when maximum river temperatures were 13.0-18.4 oC. We observed no tagged Atlantic sturgeons in the river in successive years. Except for use of the saline reach during spring, the two species were spatially separate.

Seven fish in 1989 and six fish in 1990 were tracked intensively to identify the timing and location of spawning and to characterize spawning habitat. In mid-April 1989 and 1990, fish moved upstream to just below head of tide, concentrating in a 2-km reach at river kilometers 30-32 (measured from the mouth) at Haverhill, Massachusetts. The estimated spawning time was a 5-d period (26-30 April) in 1989 and an 8-d period (22-29 April) in 1990. Spawning sites covered about 10.5 ha in 1989 and 13.5 ha in 1990. Fish spawned as river temperature increased from 9.6 to 14.0 oC and river discharge decreased from 390 to 240 m3/s. Physical characteristics of spawning sites were boulder-rubble substrate, water depth of 1.8-5.5 m, and bottom water velocity of 0.3-0.7 m/s. We captured no ovulating females but verified successful spawning in 1990 by capturing two live embryos. Gill-net captures and telemetry during spring showed that some males moved to the spawning area annually. The low abundance estimates of spawning fish (9 in 1989 and 16 in 1990) indicate that the shortnose sturgeon population in the Merrimack River is the smallest yet identified as is likely vulnerable to extirpation.o 8 N       1996 Issn 0002-8487 English Journal Article ASFA 1: Biological Sciences & Living Resources; Animal Behavior Abstracts; Ecology Abstracts^WKline, T.

Biota in Iliamna Lake had higher D15N compared with control lakes, verifying a mixing model correlating D15N with MDN. Periphyton D15N values reflected localized input from populations of spawning salmon. Juvenile sockeye MDN varied in response to escapement size, suggesting the importance of large escapements (>10 million) for maintaining a predominantly MDN lacustrine N pool. Other resident fishes showed shifts in D15N between years of high and low escapement. The dual-isotope approach, using D15N and D 13C together, suggested that fish production is primarily dependent on limnetic primary and secondary production. The dual-isotope approach indicated that the coast range sculpin Cottus aleuticus was the only fish with an appreciable dietary component consisting of salmon eggs or emergent fry.                    , -  / N O  Q          \ l ^X1993 Issn 0706-652x English Journal Article Ecology Abstracts; Water Resources Abstracts  Jirka, K.

The mucket is a long-term brooder, spawning in mid-summer, brooding glochidia throughout fall and winter, and releasing them in spring. The spike, purple wartyback, and pistolgrip are short-term brooders. Spawning began in mid-March and continued into May for T. verrucosa , into June for C. tuberculata , and into July for E. dilatata . Glochidia were release upon maturation, beginning in mid-April and continuing through June for T. verrucosa , into August for E. dilatata , and extending from March through June for C. tuberculata.

The purpose of the project was to maintain navigation from the confluence of the Missouri River to the confluence of the Ohio River. The main channel will be contracted to 1500 ft between riverward ends of dikes throughout the area to maintain the 9-ft depth during periods of low flow. A comprehensive study of the historical geomorphology supplemented by physical models of the river and side channels was made to determine the physica impact of river contraction works on river morphology and behavior. An intensive study of the terrestrial flora and fauna was conducted to inventory the existing organisms and communities located in the unprotected floodplain and to assess the impacts of operation and maintenance activities. The aquatic flora and fauna were studied to inventory the aquatic communities present in the study area and to assess the importance of side channels to the riverine ecosystem. The relative biological importance of each side channel, established by ranking procedures, provided a rational choice of those side channels that could provide maximum benefit to the river 's ecology. Operation and maintenance activities include maintenance dredging, disposal of dredged material, and construction and maintenance of levees, dikes, and bank revetments. The mentioned activities were examined, and the potential environmental impacts resulting therefrom were discussed.

Q1 01483 Species interactions: general; D 04700 Managements`Predation on recently released larval American shad Alosa sapidissima was quantified in the Juniata River, Pennsylvania, on 10 occasions during 1991 and 1992. Of the four sites examined (the stocking site and 100, 200, and 350 m downstream) predation on shad larvae was highest at the stocking site; 44% of the total estimated losses occurred within this 30-m zone. Percentage predation mortality was weakly and inversely related to the number of shad larvae released, and it ranged from 0 to 2.2% among sites. Overall percent mortality of larvae within the first 2 h of release was about 5% (range, 2-10%). Major predators included juvenile smallmouth bass Micropterus dolomieu, the spotfin shiner Cyprinella spiloptera, and the mimic shiner Notropis volucellus. Predation by these species varied among sites. Percent mortality of American shad larvae after nocturnal releases (0.17%) was significantly lower than after diurnal releases (1.18%). For most predators, the length of shad eaten increased with predator length. However, among predators of similar size, there were significant differences in the length of shad consumed. Estimated losses to predation were about equally divided among small (<50 mm, 30%) medium (50-99 mm, 37%), and large (>99 mm, 33%) predators. Because 30% of the estimated number of shad larvae lost to predation were eaten by predators less than 50 mm long, releasing slightly larger shad might reduce predation.  4 E       tm1995 Issn 0275-5947 English Journal Article ASFA 1: Biological Sciences & Living Resources; Ecology Abstracts}  Ferris19755$ Finlay19969, Finn1988 Fisher20000 Fisher20011# Flecker1993aFlint-Petersen1987 Flowers1972nFormagio1991 Frazer19999 Frear1997cFremling1984dFremling1987bFremling1989f Frost1989\ Fruget1992 Fryer1998 Gaudet1991 Gaugush1993 Gaugush1998] Gebler1998` Gehrke1995 Gende1998) George19989S Gibbs1991 Giefing1998' Gillet19988n Godinho1991n Godinho1991 Goering1993 Goettel1997pGollmann1998 Goosney1998 Gosset19955W Gowan1994 Grady1998 Grady2000r Graham1997s Grande1998_Gregoire1987Grubauch1989P Gumpinger1997c Gurram1999 Guthrie1995h Gutreuter1992 Gutreuter1993} Gutreuter1997e Gutreuter1997f Gutreuter1997 Gutreuter1998 Guttman1997 Guttman1998 Haag1997i Hackney1980 Hackney1986 Hahn19949vHaidvogl19989 Hall1972{ Hall19888" Hammer1995 Han1980 Harden-Jones1968 Hardy1992 Haro1997D Haro1998C Haro1999 Harris1984 Harris1984 Harris19900 Harris1992e Harris1992e Harris19939 Harris1998P Harris1998y Hartfield1997 Harvie1990 Harvie1990 Hatch1998z Hauer1988{ Hawkins1988n Haymes1984wHeggenes1988 Heidenreich1995Helfrich1999 Hendershot19846 Henderson1989 Henry1994 Hering19979 Herzog19969 Herzog19979x Hesse1987 Hesse1989r Hesse1993t Hesse1994u Hesse1994v Hesse1994 Hickman1980 Hiebert1999 Hill1995 Hillegass1997O Hinterhofer1998 Hocutt19878 Hoeh1997 Hoeh1998eHoffmann1993 Hoggarth1992iHolbrook19802 Holcik19900 Holland1984Holland-Bartels1988Holland-Bartels1989Holland-Bartels1990Holland-Bartels1993 Hooli1988 Hooli1998!

From videotape records and visual counts, grass carp were estimated to range between 55 and 77 cm in total length (TL). One 7.7-kg, 86-cm individual captured in a gill net was identified as a sterile triploid. Although the source of these fish is unknown, their appearance in the Columbia and Snake rivers might have been related to extensive flooding that occurred in western Washington and Oregon in February 1996. The unintentional escape of grass carp into this large river system reemphasizes the need for the current requirement that all grass carp stocked in Pacific Northwest lakes be sterile triploids. It also suggests that increased attention to effective barrier construction and maintenance is important to prevent grass carp impacts in nontarget areas.  3 Mar 1999 Issn 0002-8487 English Journal Article ASFA 1: Biological Sciences & Living Resources; ASFA 3: Aquatic Pollution & Environmental Quality; Water Resources Abstracts@2"Rajaratnam, N.

Baffles with heights equal to 0.15 and 0.1 times the diameter (D) of the culvert were studied with longitudinal spacings of 0.6D and 1.2D. Equations have been developed to describe the relation between the discharge, slope, diameter, and the depth of flow. It has been possible to predict the barrier velocity that would exist at the baffles. The performance of the weir baffles has been found to be as good as that of the slotted-weir baffles.lfAug 1990 Issn 0315-1468 English Journal Article ASFA 2: Ocean Technology Policy & Non-Living Resources"Rajaratnam, N.

Using theoretical considerations and experimental observations, an expression has been developed that relates the flow rate, slope of the fishway, and depth of flow. It was also found that the characteristic (similarity) velocity profile found earlier, for smaller values of depth to width ratio, y sub(0)/b, with the maximum velocity near the bottom, changes to a rather symmetrical profile with the maximum velocity occurring somewhere near the mid-depth for larger values of y sub(0)/b. A correlation has also been found for the maximum velocity. This paper also includes some observations on the M-type backwater curves that would appear in the fishway when the tailwater depths exceed uniform flow depths.1991 English Journal Article ASFA 2: Ocean Technology Policy & Non-Living Resources; ASFA 1: Biological Sciences & Living Resources; ASFA 3: Aquatic Pollution & Environmental Quality  Lee1998 Legault1992e Leggett1986 Lein1998 Lelek1986 Lelek1987 Lelek1992 Leonard1997 Libby1981 Liew1982 Lindner1985 Lispi1987 Liston19999 Littlejohn1984, Liu1998 Loch1999b Lodewyk1988 Long1994{Lowe-McConnell1988Lubinski1991Lubinski1993Lubinski1993Lubinski1995 Lucas1996 Lucas1997 Lucas1999P Lugg1998g Lupton1995 Lynch1994 Macins1978 Mackay19858 Mader1998 Madsen19939 Maeki-Petaeys1998 Mahon1984c Mainali1988d Mainali19891 Malevanchik1988 Mallen-Cooper1992 Mallen-Cooper1992 Mallen-Cooper1999 Mann19882 Mann19909 Mann19939 Mann1996 Maracek1996 March1999 Markillie1991Markmann1993 Marsden1997 Marston1998 Martin1994Matheney1995Mathisen1993s Matzow1998  McCutcheon1994 McGinty1999McIninch1987McKinley1995McKinley1997McKinley19988)McKinley19999McKinley2000!

Many of the pools formed by these navigation dams have nearly reached a new equilibrium condition for scour and deposition of sediment. Several pools with extensive backwater or channel border areas are still accumulating sediment at rates similar to those for man-made lakes. The original open-water habitats in these pools are changing to aquatic macrophyte beds and then to marsh or terrestrial floodplain conditions because of sediment deposition. Two pools are used as examples of this phenomenon. 1) Pool 19 on the Mississippi River was formed when the lock, dam, and power house at Keokuk, Iowa were completed in 1913; and 2) Peoria Lake which has been affected by the diversion of Lake Michigan water into the Illinois River in 1900 and the construction of a lock and dam in 1939. Both pools have had well over 50 percent of their original volume filled with sediment. Three areas in Pool 19 illustrate the successional changes that occur as sedimentation raises the river bottom into the photic zone. Sedimentation has made boating impossible on large areas of both pools. The continuing process is likely to change open waters to floodplains. Peoria Lake lacks aquatic plant beds because of excessive turbidity and frequent resuspension of bed material by wind- or boat-generated waves. It seems likely that these river reaches will become a narrow channel without any broad and highly productive channel borders. Conference 4.

The Upper Mississippi River System (UMRS) is used extensively by commercial barge traffic. The research involves collecting a comprehensive set of data and analyzing these data for the development of various functional relationships. These relationships will form the starting point for the determination of biological changes that may be associated with the frequent movement of commercial traffic within large river systems. Ultimately all the functional relationships will be used to formulate and develop comprehensive management alternatives for the UMRS.3yEMTC93R017, , 1993, 18 pp NTIS Order No.: PB94112109XSP.

The changes in the river environment resulting from the movement of such traffic may include creation of waves and drawdown, altered velocity and pressure regimes, resuspension and lateral movement of sediment, and temporary changes in flow direction due to the return flow. Research has been initiated to determine the physical changes associated with navigation within the Illinois and Mississippi Rivers. Field data on various hydraulic and sediment resuspension characteristics have been collected and analyzed to determine functional relationships. These physical relationships will be used in the biological models to identify and determine changes in the aquatic environment due to navigation traffic. The paper discusses some of the physical changes in a large river environment due to navigation traffic. Biological effects of navigation are given in a companion paper that follows this article.Rept. No: EMTC93R019, , 1993, 17 pp NTIS Order No: PB94108917XSP.

Monitoring in rivers is one of the more challenging applications for fisheries acoustics. Rivers typically have a high reverberation level, uneven bottom bathymetry, and nonlaminar hydraulics, requiring sophisticated equipment and careful deployment, calibration, and testing. The major issues that were addressed in order to obtain estimates of adult salmon escapement included hydroacoustic equipment and techniques, site selection, transducer deployment, and fish behavior. Fixed-location hydroacoustic techniques were employed, utilizing narrow-beam transducers aimed horizontally, monitoring migrating fish in side-aspect. Fish were tracked in three dimensions as they passed through the acoustic beam. A bottom substrate of low acoustic reflectivity enabled the acoustic beam to be aimed close to the bottom. Sites were selected where fish were actively migrating, not holding or milling. In most cases, migrating salmonids were strongly shore- and bottom-oriented, where water velocities were slowest. Diel distributions of fish passage were weighted toward nighttime. Other results included fish size and velocity. Potential improvements in riverine monitoring capabilities include quadrature demodulation and FM Slide/Chirp signals.f e  May 1998 Issn 0165-7836 Special Issue: Shallow water fisheries acoustics.

The importance of migrations seems assured as an adaptive feature of major significance in production of freshwater fish, especially in environments subject to sharp temporal fluctuations or to marked spatial patches in habitat fertility. Studies to determine more precisely the degree to which these phases of migration regulate production are badly needed together with the extent to which they can purposefully be used to better exploit the phenomenon in production of species useful to man.vpIn : Ecology of freshwater fish production English Book Monograph ASFA 1: Biological Sciences & Living Resourcesw Waller, D.R. 1988;Studies on Lampsilis mussels of the Upper Mississippi River    *#Biological Sciences and Engineeringc Ames, Iowa (USA) Iowa State University  210rPh.D. Dissertation DA8805149eRare species; Life history; Parasites; Hosts; Lampsilis; USA, Mississipi R.; mussels; glochidia; glochidial hosts Freshwater Q1 01261 General  2The glochidial stage of the endangered freshwater mussel, Lampsilis higginsi, and several related species was studied to provide information on their early life histories. The glochidia of L. higginsi and the three species, L. radiata siliquoidea, L. ventricosa, and Ligumia recta, were compared using morphometrics and scanning electron microscopy (SEM). The glochidia of L. higginsi were morphometrically similar to those of the related species; however, they could be distinguished using SEM by the position of the hinge ligament and the dorsal ridge width. Fifteen species of fishes were tested for their suitability as hosts for the glochidia of L. higginsi. The following were found to produce at least one juvenile mussel: northern pike Esox lucius, brook stickleback Culea inconstans, bluegill Lepomis macrochirus, green sunfish L. cyanellus, largemouth bass Micropterus salmoides, smallmouth bass M. dolomieui, yellow perch Perca flavescens, and walleye Sitzostedion vitreum vitreum. A test of host quality using three members of the Family Centrarchidae ranked smallmouth bass highest with a transformation of 7.68%, followed by green sunfish (2.43%) and bluegill (0.00038%). Two propagation methods for juvenile Lampsilis mussels were tested. In vitro culture averaged 1.28 juveniles/plate, with a transformation of 1.05%. Transformation averaged 15-24 juveniles/fish on infected host fish. The pathogenesis associated with L. radiata siliquoidea on a suitable (walleye) and an unsuitable host (common carp) was compared using light and transmission electron microscopy. Encapsulation of glochidia on walleye gills was completed by 4-6 hr at 21 oC. At 24-48 hr, the capsule was thin and compact. Fibrous tissue appeared in the capsule at 48 hr and increased in quantity to the end of the infection. Excystment occurred by thinning of the capsule aided by movement of the juvenile. Most of the glochidia attached to the common carp gills did not encapsulate. Partial capsular growth was evident in some, but the portions of the capsule distal to the bite consisted of necrotic cells and debris. A few complete capsules were found at 12-48 hr; however, all glochidia were sloughed by 60 hr. There was no evidence of leucocytosis; however, the number of heterophil type cells was greater in the capsular tissue of the common carp than in walleye.% : L          u        " 5 E Q c x           x  y DISS.

Many such crossings are impassable to migrating fish because of the culvert length and the high water velocities in them. A hydraulic model study tested and developed devices to aid fish passage through culverts. Based on the model study recommendations, Offset baffles and Spoiler baffles were designed and installed at the Mackenzie Highway crossing of the Redknife River. Field testing showed good agreement, between model and prototype results. The effectiveness of both baffle types is inversely proportional to culvert slope. Maximum recommended slope is 5%. A method of judging baffle adequacy is provided. The Offset and Spoiler baffles are recommended, primarily for correcting existing culvert installations and for proposed stream crossings where alternative designs are neither practical nor economical. Minor problems were presented by ice, debris and sediment. Unsuccessful attempts by Arctic grayling Thymallus arcticus and longnose sucker Catostomus commersoni, to enter the Redknife River culverts, were observed; their failures were attributed to overwhelming water velocities associated with elevated culvert outlets.t      Dec 1978, 83 p, Tech.

In culverts stream flow velocities are maximized and usually constant throughout most of the culvert length as opposed to the variety of conditions in a natural stream channel. From documentation of swimming ability of salmon (Oncorhynchus ) it is possible to determine hydraulic criteria that must be satisfied to ensure free fish passage, especially throughout the spawning migration period. Since detailed stream flow records for small streams in British Columbia have not been taken, a general system must be used. Some recommendations for culvert design are given.

The report also outlines guidelines that, if incorporated into the culvert design, should produce a facility that will permit the free passage of fish in most situations. The design of auxiliary fish passage structures such as culvert baffles and tailwater control facilities are discussed and exampled by drawings. Consideration is also given to the installation of culverts to avoid conflicts with fish use in the stream both during and after the construction period. Guidance is also given concerning the procedures to follow for necessary approval of a proposed culvert installation by the Fisheries and Marine Service.gOct 1978, 2 ed. 62p, Tech. Rep. Fish. Mar.

In association with commercial harvest for the pearl button industry and construction [sic] of Dam 19, early researchers predicted a reduction in the mussel populations of the river. Qualitative construction and quantitative records for the past 75 years were examined to determine if changes have occurred and to evaluate those changes in the mussel community. While commercial mussel harvest rapidly declined in the 30's and 40's it has again become a prevalent activity on the river with tons of mussels being removed from the river annually. In 1930, 21 species of mussels were collected from this Pool while in the mid-1980's 29 species were present. Sampling effort and the number of habitats examined increased in the 1980's. Even though simple diversity may have increased, density has decreased. Though more species are presently reported from this river reach, shifts in density and composition have occurred with previously abundant species becoming rare."Angermeier, P.L. Karr, J.R. 1994LEBiological integrity versus biological diversity as policy directivesc BioScience44690-6972+diversity biodiversity biological integritycThe authors argue that resource policy would be most effective if the goal were the protection of biological integrity. Biological integrity is defined as biological diversity plus the processes that support that diversity. Thus, it is a truer systems approach to resource management than just managing for the greatest different types of organisms. In their argument, the authors stress the importance of understanding organizational heirarchies in ecosystem management. Objective recognition and assessment of changes in integrity are critical for the concept's use in resource policy. Thus, appropriate benchmarks need to be established against which future system states can be compared and contrasted. Variation in elements attributable to natural processes does not represent a variation in integrity, but variation caused by humans does. The authors argue further that evolotionary history should provide the primary basis for assessing biological integrity. A keystone concept in their argument is that ecological processes are buffered from perturbation by redundancy among ecosystem elements and processes. Anthropogenic influences often simplify systems, reducing their redundancy, and thus negatively impair system integrity. In essence, the goals of biological conservation and restoration should focus on protecting integrity, especially the organizational processes that generate and maintain all elements, rather than focusing on the presence or absence of particular elements.

The main report summarizes the findings of the 17 supporting appendices. The water and related land resources of the basin are ample. There are opportunities for further resource development. Conservation and development of the resources are needed if the basin is to maintain its relative position in the national economy. The study presents the needs for water and related land resources and a framework for development of such resources. The estimated total first cost of the recommended framework for development is $28.5 billion of which $13.2 billion is federal and $15.3 billion is non-federal. The annual investment ranges from $31 per capita in 1980 to $44 per capita by 2020. The current annual rate of investment is about $27 per capita. Recommendations include approval and adoption of the framework by the federal government and the seven basin states, further studies to develop details of the framework, periodic review of the framework, and continuation of the present coordinating committee pending organization of the Upper Mississippi River Basin Commission.

Large dams tend to have particularly significant and complex effects on aquatic ecosystem which must be carefully evaluated prior to construction. Rational development involves: (1) a comprehensive basinwide assesment of social, economic, and ecological characteristics and of the effects of development; (2) evaluation of development alternatives reflecting social, economic, and environmental factors to provide the basis for environmental management. Dam construction can provide the water supply, hydroelectric power, and flood control, and can greatly improve agriculture, forestry, and livestock management. Excessive use of water and agricultural chemicals can however, cause waterlogging and salinization, and can affect water quality and quantity. Dams produce a permanent physical transformation, inundating settled areas and destroying habitats , affecting the groundwater regime and water table, possibly increasing seismic tendencies, and often leading to explosive aquatic weed growth and the spread of schistosomiasis and other communicable diseases. Dams in tropical areas tend to favor weed propagation and vectors of parasitic diseases, while temperate-zone dams often interfere with fish migration. Resettlement of population displaced by dams often leads to housing, disease, and social problems. Loss of wetlands endangers many plant and animal species.Water Management and Development, Proceedings of the United Nations Water Conference; Mar del Plata, Argentina March 1977.

As a result of the magnitude and immediacy of the nationwide threats to the freshwater mussel fauna, the group agreed that a coordinated effort of national scope was needed to prevent further mussel extinctions and population declines. To address this need, the group decided to (1) draft a National Strategy for the Conservation of Native Freshwater Mussels (National Strategy) and (2) establish a national ad hoc committee with broad-based representation from state, tribal, and federal agencies, the mussel industry, private conservation groups, and the academic community to help implement mussel conservation at the national level. A draft National Strategy was presented at the second Symposium on the Conservation and Management of Freshwater Mussels organized by the Upper Mississippi River Conservation Committee, in St. Louis, Missouri in October 1995. Comments received at and subsequent to the symposium were incorporated into another draft dated September 16, 1996. The September 1996 draft was presented at a February 1997 meeting of the newly formed National Native Mussel Conservation Committee in St. Louis, Missouri.

Distances covered by some sturgeons during spawning migrations show a positive relationship to average adult size. The lake sturgeon, Acipenser fulvescens, is the only sturgeon endemic to the Great Lakes basin. Most remaining populations in the basin are restricted in movement, yet in a few, free-ranging populations still remain. Study of these populations will more adequately define range and habitat preferences of the species. Some state and federal agencies are now creating management plans for lake sturgeon. Those plans need to be based on information gathered from free-ranging groups. A barrier-free 250-300 km combined river and lake range is suggested as a minimum distance to support self-sustaining populations and distances of 750-1000 km should not be considered unusual. Fishery managers should give barrier removal or fish passage greater consideration than habitat enhancement for populations currently isolated and restricted in range.

By comparing different discharges and various entrance locations of a simulated fishway, we found that the most effective position for the entrance is parallel to the tailwater flow and directly at the obstacle. In contrast, entrances at right-angles to the flow can hardly be found by the fish. On their way upstream, they pass the zone of turbulence and assemble immediately in front of the migration barrier.rOriginal Title Zur auffindbarkeit von fischaufstiegsanlagen - verhaltensbeobachtungen an fischen in einem modellgerinne Apr 1998 Issn 0043-0951 German Journal Article Water Resources Abstracts@9Adams, S.

Fifteen-minute critical swimming speeds ranged from 65 to 116 cm s-1. Sturgeon swam volitionally at low speeds (5-30 cm s-1), but at higher speeds (40 - 120 cm s-1) sturgeon alternated between active swimming and appressing themselves to the bottom of the tunnel. This second behaviour is enhanced by sturgeon morphology - streamlined body shape, flat rostrum, and large pectoral fins. It allows shovelnose sturgeon to exploit river bottoms as a refugia from current and maintain position in high velocities.  _ z       #  % K  M `Z1997 Issn 0270-5060 English Journal Article ASFA 1: Biological Sciences & Living Resourcesc 8$Fremling, C.

This section of the river was surveyed in the early 19th century. The beginning of steamboat travel in 1823 led to navigation improvements by the Army Corps of Engineers starting in 1824. Settlements continued to grow in number and population, stimulating cutting of forests for lumber and agricultural activities, particularly steepland farming. These practices contributed to erosion and degradation of the river system. The Rivers and Harbors Acts of 1878, 1890, and 1907 resulted in channel deepening and other construction works in the section from Minneapolis to the Ohio River. These works used wing and closing dams, shore protection, and auxiliary dredging, permitting open-channel navigation. By 1870 the fisheries were rapidly declining as a result of wide fluctuations in water level which stranded fish in backwaters. Fish rescue operations were begun in 1879 and continued until the 1950 's in a few locations. In the 1930 's more extensive channelization projects started. The channel was deepened to 9 ft by construction of locks and dams (29 built during this period), supplemented by dredging. As a result of the impoundments, the river habitat has changed, vastly increasing the marsh area and slack water area habitat available for invertebrates, periphyton, fish (139 species), furbearers, and waterfowl. Some long-term detrimental changes caused by the channel modifications include accelerated sedimentation (changing wetlands into floodplains), eutrophication, and accumulation of industrial wastes.Contaminants in the Upper Mississippi River: Proceedings of the 15th Annual Meeting of the Mississippi River Research Consortium , Butterworth Boston. 1984. p 5-24, 7 fig, 22 ref.

The summer population size in 1996, estimated by mark-recapture methods, was 292 individuals that were age 2 or older. Instantaneous total mortality rate (Z), estimated with a catch curve, was 0.41, for an annual mortality rate of 34%. Modeling the population with Z = 0.41 resulted in declining populations under two different recruitment scenarios. Mortality rates will have to be reduced to Z = 0.16-0.24 for the population to be self-sustaining by 2023, the target year in the Gulf Sturgeon Recovery Plan. Mean fork length of Gulf sturgeon in the Pearl River system was significantly larger in 1970 than in 1985 and 1992-1996, indicating that the population may not have improved since 1985. An increase in population size should be detectable within 6 years of achieving acceptable levels of mortality. Efforts to reduce mortality should focus on commercial bycatch and improving winter habitat in the Lake Pontchartrain estuary and summer habitat in the Pearl River system. Weirs in the Pearl and Bogue Chitto rivers need further study to determine if improved fish passage would improve recruitment and survival of Gulf sturgeon.; * > Nov 1998 Issn 0275-5947 English Journal Article ASFA 1: Biological Sciences & Living Resources; ASFA 3: Aquatic Pollution & Environmental Quality; Water Resources AbstractsB8Proceedings of the Mississippi River Research Consortium La Crosse, Wisconsin (USA) ,%Mississippi River Research Consortium 2914.'freshwater mussels glochidia fish hoststOf 297 freshwater mussels species living in North America, 213 are either endangered, threatened, or of special concern. The identification of fish hosts is listed in the National Strategy for Freshwater Mussel Conservation as an urgent research objective. We conducted laboratory studies to determine suitable fish hosts for three species of freshwater mussels: strange floater Strophitus undulatus, ellipse Venustaconcha ellipsiformis, and snuff box Epioblasma triquetra. Various fish species were exposed to mussel larvae via artificial infestation. A fish was considered a suitable hosed when larval metamorphosis to the juvenile stage was observed. Juvenile strange floater were collected from five of seven species tested: largemouth bass, green sunfish, black bullheads, bluegills, and yellow perch. Of nine fish species exposed to ellipse glochidia, only blackside darters were suitable hosts. Snuff box glochidia metamorphosed on log perch and blackside darters. Host requirements for strange floater glochidia appeared to be quite general, whereas the ellipse glochidia were more selective. Species-specific molecular markers are being developed for use in the identification of glochidia collected from naturally infested fish. }      Hoggarth, M.A. 1992An examination of the glochidia-host relationships reported in the literature for North American species of Unionacea (Molluske: Bilvalvia).Malacology Data Net3 1-30TNmussels; glochidia; host species; glochidia-host fish relationships; unionaceaThis was an extensive list of many of the parasite-host relationships from the literature.

Beside variable outlets on account of the natural catchment area, the fish ladder at the Kellerberg Loop took the performance of the fish, disposition of the fish path and sufficient decoy current into consideration. The fish ladder was well accepted and serves as permanent living space for at least 10 different species of fish. The fish ladder also serves a good purpose with regard to ascents during the spawning time.Original Title Messungen an der Fischaufstiegshilfe von der Drau in die Kellerberger Schleife 1991 Issn 0029-9987 German Journal Article ASFA 3: Aquatic Pollution & Environmental Quality62"Hubley, R.C., Jr. 1963HAMovement of tagged channel catfish in the Upper Mississippi River4.Transactions of the American Fisheries Society922s165-168tNHchannel catfish movements migrations Mississippi River dams fish passageResults from a tagging study on Mississippi River channel catfish from Bay City, WI to Lansing, IO are presented. Greater than 6100 individual fish were tagged, with returns coming from both recreational and commercial fisheries operating on the river. Five "batches" of fish were tagged. Some of the batches were released at the site of capture (residents) while others were re-located greater than 100 miles from the capture site (transplants). Resident fish movements were described as principally downstream. A majority of transplanted fish were reported to move upstream, in contrast to resident fish. No evidence of homing was observed. The effects of obstructions (dams) are discussed. The author reported that the locks and dams on the Mississippi River did not present obstacles to channel catfish movements within the river. Nearly a quarter of the recaptured fish had moved through one or more dams. No information of the directionality of passage through the dams is provided (e.g., upstream vs. downstream passage).

Analysis of performance data usually employs a simple comparison, in which the mean of a stressed group of fish is compared to that of a control group. Although such a comparison is satisfactory in many cases, a comparison emphasizing individual variation in performance can yield valuable information unattainable by a means comparison. In this experiment, we determined critical swimming speeds of subadult male fathead minnows before and after exposure to contaminated sediments from Devil's Swamp, Louisiana, USA. The data were then analyzed using a means comparison and an individual approach to illustrate the differences in explanatory power between the two approaches. 6 I Feb 1998 Issn 0730-7268 English Journal Article Toxicology Abstracts; Pollution Abstracts; Water Resources Abstracts; ASFA 3: Aquatic Pollution & Environmental Quality5 Kolok, A.

Drawing on advances made in herpetofaunal studies, an alternative approach has recently appeared in the fish literature in which variation among individual fish has been shown to be repeatable and statistically valid. The incorporation, rather than suppression, of individual variation in experimental design has revealed interesting and biologically relevant relationships between morphological and physiological traits and swimming performance that can be masked by the traditional use of group means. Considering the promising nature of these initial studies incorporating individual variability in fish performance, this paper has two primary objectives. The first is to compare methodologies that have been used in studies involving intraspecific variability in the locomotor performance of fish and herptofauna. The second is to review the fish literature regarding interindividual variation in prolonged swimming performance.`Z1999 Issn 0706-652x English Journal Article ASFA 1: Biological Sciences & Living ResourcesN @9Past, present, and future concepts in large river ecology4-Johnson, B.

Introducing water from the main channel can increase oxygen levels in backwaters, but can also increase current velocity and reduce temperature during winter, which may reduce habitat suitability for fish. In 1993, culverts were installed to introduce flow to the Finger Lakes, a system of six backwater lakes on the Mississippi River, about 160 km downstream from Minneapolis, Minnesota. The goal was to improve habitat for bluegills and black crappies during winter by providing dissolved oxygen concentrations > 3 mg/L, current velocities < 1 cm/s, and temperatures > 1 oC. To achieve these conditions, we used data on lake volume and oxygen demand to estimate the minimum flow required to maintain 3 mg/L of dissolved oxygen in each lake. Estimated flows ranged from 0.02 to 0.14 m3/s among lakes. Data gathered in winter 1994 after the culverts were opened, indicated that the estimated flows met habitat goals, but that thermal stratification and lake morphometry can reduce the volume of optimal habitat created.

Structural and management changes to the fishway which may improve its efficiency are proposed.RK1981 English Journal Article ASFA 1: Biological Sciences & Living Resources:  Kolok, A.S. 1992[The swimming performance of individual largemouth bass Micropterus salmoides are repeatable 7 L &Journal of Experimental Biology  170c265-270g0)Largemouth bass bass swimming performancev`Previous studies have shown that critical swimming speed (Ucrit) of the largemouth bass, Micropterus salmoides Lacepede, is significantly influenced by a number of factors including body mass, training, water temperature and photoperiod. Recent research into locomotor performance of amphibians and reptiles has suggested that individual variation is substantial and repeatable. The results of this study suggests that variation in the swimming performance of individual and juvenile largemouth bass is substantial and repeatable for fish tested twice at one temperature, tested at different temperatures, or tested after a 4 week acclimation to different temperature. These results strongly suggested that individual variation in Ucrit is more than statistical noise and that it is a source of variation that can be exploited when designing future experiments. ; @?

Subadult fish were allowed to grow into adults over a period of 31-55 days, after which the critical swimming speed of each fish was determined. Variation in critical swimming speed was substantial (greater than 50%), and a significant positive correlation was found between number of growing days and critical swimming speed, whereas a significant negative correlation was found between specific growth rate and critical swimming speed. A multiple regression using specific growth rate and number of growing days explained over 47% of the variation in swimming performance. Fathead minnows that grow fast are poor swimmers, suggesting a trade-off between swimming performance and specific growth rate in this species. m  Nov 1995 Issn 0008-4301 English Journal Article Animal Behavior Abstracts; Ecology Abstracts; ASFA 1: Biological Sciences & Living Resourcesm Ryman1987k Sabur1997 Saila1972< Sandell1994 Sanders1987=Sanguine1985 Scalan19939# Scarnecchia1992C Scarnecchia1997 Scatena1999 Schell1995`Schiller1995 Schmulbach1989 Schmutz1998 Schmutz1998 Schmutz1998[ Schmutz1998+ Schrank1996 Schupp1978Schwalme1985 Schwartzberg1998 Schwevers1998+ Scott1973 Scruton1995 Scruton1997 Scruton1998 Scruton2000q Sedell19800h Sedell19855 Seeb1987 Seeb1987 Seibel20000 Senanan2000 Sheehy1972?

An initial study of 707 recently licensed hydropower projects in the United States indicated that approximately 11% were required to provide upstream fish passage and 28% were required to provide downstream fish passage. Despite considerable effort to design and install fish passage devices, many projects had no detailed performance criteria and no performance monitoring requirements. A follow-up study examined the effectiveness of fish passage mitigative measures at 16 hydropower projects that had conducted performance monitoring. Fish ladders and lifts can be very effective in moving fish upstream past a dam; some of the case study projects were nearly 100% effective. Three of the 12 case studies with downstream passage measures have successfully increased the survival of downstream-migrating fish. However, in other instances the devices have failed or, more commonly, operational monitoring has not been adequate to make a judgement about their effectiveness. As an alternative to downstream fish passage screening, the DOE Advanced Hydropower Turbine Systems Program has begun a phased effort to design, build and test fishfriendly turbines, i.e. turbine systems in which environmental attributes such as entrainment survival, instream flow needs, and/or water quality enhancement are emphasised. Such turbine systems could allow the efficient generation of electricity while miniraising the damage to fish and their habitats.Conference Fish Migration and Fish Bypass Channels Symp., Vienna (Austria), 24-27 Sep 1996 Fish Migration and Fish Bypasses, Fishing News Books, 1998, pp. 208-219 Price: pound sterling 65.

Ecological integrity is impossible without biological integrity. However, it appears improbable that highly localized measures of biological integrity can be used for effective, scientifically justifiable extrapolations to landscape- or system-level ecological integrity. It may be more reasonable to make measurements at the level of organization of interest, i.e. larger spatial and temporal scales. In addition, human society and natural systems have been coevolving since the agricultural revolution and, arguably, well before then. Two types of coevolution between human society and natural systems appear possible: (1) an 'arms-race' in which human society ignores changes in natural systems-essential ecosystem services are lost, resulting in unpleasant consequences for society; or (2) mutualism in which environmental literacy and a feeling of responsibility for natural systems motivate rapid societal response to ecosystem changes and the preservation of ecological integrity. The simplest measures of ecological integrity may be the actions of human society likely to minimize or markedly reduce negative impacts on natural systems. This does not mean substituting such measures for more customary ecological measures, but rather using both types of measurements simultaneously.0Conference Conference on Sustaining the Ecological Integrity of Large Floodplain Rivers: Application of Ecological Knowledge to River Management, La Crosse, WI (USA), 12-15 Jul 1994 1995 Issn 0886-9375 English Journal Article; Conference; Review Water Resources Abstracts; ASFA 1: Biological Sciences & Living Resources; ASFA 3: Aquatic Pollution & Environmental Quality; Ecology AbstractsCambray, J.

The dominant group of fish consisted of juvenile moggel Labeo umbratus . There were also small-scale redfin minnows Pseudobarbus asper , Mozambique tilapia Oreochromis mossambicus and several chubbyhead barbs Barbus anoplus . Fish accumulated below a weir and began to migrate late in the morning. Migration activity continued throughout the afternoon until dusk when the fish dispersed downstream. The observed movement of fish was clearly a diurnal migration. The weir had altered the general riverine habitat and influenced the natural migratory movement of fish within the Gamtoos River system. Data are presented which would be useful in the design of a fishway at this weir.

In some cases, habitat destruction and the loss of mussel populations is essentially permanent as in the case of the construction of dams which inundate riverine habitat, change water quality, and eliminate hosts fish populations. In many other cases, the factors responsible for the extirpation of mussel populations have largely been corrected and conditions may now be suitable for the reestablishment of mussels; however, it is suggested that during the intervening time between the extirpation of mussels and improvement in stream conditions other factors affecting stream hydraulics may prevent the successful reintroduction of mussels. In particular, land-use practices within watersheds may have profoundly affected stream hydrographs by increasing peak discharges following precipitation and decreasing base flows during dry periods. Lower base flows may expose mussel beds, eliminate settlement of juveniles from otherwise suitable habitat, and affect host fish population dynamics and movements. Conversely, results of recent research indicate that high shear stress associated with peak discharge is likely responsible for unsuccessful settlement of juvenile mussels in a headwater stream. Measuring or modelling simple hydraulic variables such as mean water column velocity is inadequate for assessing the affects of altered stream hydrographs on potential mussel habitat. In contrast, complex hydraulic variables such as shear stress and Reynolds boundary number are potentially better predictors of hydraulically suitable sites for mussel reintroductions.Conference 88.

Computer simulations identify two life-cycle characteristics as major factors governing the abundance of a species, namely the movement range of their fish hosts and the success rate of the parasitic larval glochidia in finding fish hosts. Core mussels species have fish hosts with large movement range to disperse the parasitic larval glochidia to achieve high levels of abundance. Species associated with fish host of limited movement range require high success rate of finding fish host to achieve at least an intermediate level of abundance. Species with low success rate of finding fish hosts coupled with fish hosts having limited movement range exhibit satellite species characteristics, namely rare in numbers and sparse in distributions.Conference 19.

To achieve these aims the fish system, the fluvial system, and the system of human values and intentions must be integrated; in addition today's knowledge must be equal to the challenge. Examination of the present status of six aspects of the task shows that (1) facilitation of fish passage at dams is a very high priority but requires greater commitment, (2) hatchery production has generated unreasonable expectations and may be laying the basis for the demise of wild populations, (3) the practice of stocking fry has run ahead of its evaluation, (4) determination of instream flow requirements is bedeviled by spurious quantification, (5) drawdown requirements of impoundments seem incompatible with fishery objectives, and (6) stream habitat improvements give mixed results and may be of restricted application in terms of scale. Yet another limitation of fisheries' aspirations lies in political support. It is concluded that this is a time for stock-taking, improvement of current practices, and assessment of trends.Conference Fisheries Bioengineering Symp. 10. American Fisheries Soc.

Three species of diadromous sturgeon (Huso huso, Acipenser gueldenstaedtii, Acipenser stellatus) historically migrated from the Black Sea to the upper reaches of the Danube in Austria and Germany to spawn. However, beginning in the Middle Ages, fishing weirs were used to harvest sturgeon, sometimes blocking the entire river channel. Populations of upriver sturgeon were thus decimated long before permanent barriers to migration were constructed. Since the early 1970s, a hydropower facility at the Iron Gate in Romania (river km 931) has limited sturgeon to the lower river. Diadromous shad species (Pontic shad Alosa pontica and Caspian shad Alosa caspia spp.) also underwent historic migrations up into Hungary but were most abundant below the Iron Gate and thus still exist in some abundance. The middle and upper reaches of the main Danube channel were free of permanent migration barriers until 1927 when the Kachlet power plant was constructed; a fish ladder there demonstrated substantial movements of nase Chondrostoma nasus and barbel Barbus barbus as well as other species. This fishway, however, was the last built in the main channel for over 60 years, although within this time 29 power plants were constructed between Ulm, Germany and Vienna, Austria. Recently, two bypass systems have been built on the main channel of the Danube (Freudenau in Austria and Vohburg in Germany). The conservation of the rich Danubian ichthyofauna will largely depend on efforts to open up both the longitudinal and lateral connectivity of this alluvial river system.            ~    Conference Fish Migration and Fish Bypass Channels Symp., Vienna (Austria), 24-27 Sep 1996 Fish Migration and Fish Bypasses, Fishing News Books, 1998, pp. 85-98 Price: pound sterling 65.

Fish were marked in Pools 4 through 18 and 26. Studies included information for 15 species of fish; black crappie, white crappie, bluegill northern pike, common carp, channel catfish, freshwater drum, flathead catfish, largemouth bass, paddlefish, sauger, shovelnose sturgeon, smallmouth bass, walleye, and white bass. The total number of fish marked in 59 of the studies was 62,618. Totals were not available for the remaining 30 studies. Less than ten percent of the marked fish were recaptured. No black crappie, white crappie, bluegill, northern pike, or common carp were found to move across a single lock and dam, either in an up or down direction. Of the total number of fish recaptured in all studies 4,594 (79.7%) were in the pool where the fish was initially marked, 712 (12.4%) moved upriver and 458 (7.9%) moved downriver. We also investigated the head differential between headwaters and tailwaters for each day the fish was at large. Unfortunately, most fish were at large for fairly long periods, so we could not pinpoint the head differential when the fish actually crossed a dam. The minimum head differential during the period when fish were at large was used to conservatively estimate fish passage opportunities. Of the fish moving upriver through dams 88.0% crossed with a head differential less than 2.0 feet. Of the fish moving downriver through dams 72% crossed with a head differential less than 2.0 feet. Only 3.9% of the fish that moved upriver did so when the head differential was at least 4.0 feet and 19.4% of the fish that moved downriver did so at that head differential. Of the walleyes, which made up 53% of the total number of fish that moved, 78% moved upriver through at least one dam. Of the walleyes that moved upriver, the majority crossed 1 to 5 dams. Ninety-one percent of the sauger, which made up 15% of the observations, also moved upriver through at least one dam. In contrast, 94% of the channel catfish, which made up 20% of the observations, moved downriver through at least one dam. Of the channel catfish that moved downriver, the majority crossed 4 to 9 dams.$Martin, R. Miller, A.

Section 9142 requires the Wisconsin Department of Natural Resources, in consultation with the Aquatic Nuisance Control Council, to prepare a report to the Legislature on zebra mussels by June 30, 1994. The Governor directed WDNR and the Council to examine additional staffing needs for zebra mussel activities and to develop recommendations on an appropriate funding level and potential non-general purpose revenue funding sources for consideration in the 1995-97 budget bill. Specifically the report was to identify the following key issues related to zebra mussels: The current and potential economic and environmental impacts; The potential control strategies; The geographical areas, public facilities or activities which need technical or financial assistance to reduce the environmental, public health or safety risk caused by this species; and The adequacy of existing state resources and staffing to address the problems posed by zebra mussels. This report was compiled to meet those requirements.WISCU-T-94-001, , Dec 1994, 69 pp Book Monograph ASFA 1: Biological Sciences & Living Resources; ASFA 3: Aquatic Pollution & Environmental Quality$Matheney, M.

We determined movement and habitat use for 25 fish in the Current River, Missouri, for 1 year using radio telemetry. Seasonal movements were recorded two or three times each week during daylight hours from January to November 1988. Diel movement and habitat use were recorded once each hour for 17 d in winter and 12 d in summer. Mean daily distance traveled was greater in summer (425 m) than in winter (276 m). Home range was greater in winter and spring (812 m) than in summer and fall (426 m). Habitat use changed seasonally from slower, deeper water and smaller substrates during winter to increasing use of faster, shallower water and larger substrates through warmer-water periods. In both seasons, fish had a consistent daily pattern, moving more during the day than at night. Diel patterns of use were distinct. In winter, fish used pool habitat with moderate flow during the day and riffle or edge habitat at night. In summer, fish used run habitat during the day and riffle or edge habitat at night. Patterns of habitat use indicated fish used one area of the river during the day to feed and another at night to rest. Fish remained in their home area during high-flow events but used flooded riparian areas where current velocities were lower. Fish moved up- or downstream short distances (mean = 497 m, N = 7) into spawning areas during late February and early March. This study emphasizes the importance of habitat diversity to accommodate this species' diel and seasonal preferences and the necessity of a connected floodplain for the fish to survive catastrophic events.  ! 6 1995 Issn 0002-8487 English Journal Article ASFA 1: Biological Sciences & Living Resources; Ecology Abstracts; Animal Behavior Abstracts Northcote, T.G. 1998leMigratory behaviour of fish and its significance to movement through riverine fish passage facilities *$Jungwirth, M.

Usually it involves, at some stage in the life cycle, both upstream and downstream movements to reach the appropriate habitats. Upstream phases of migration are active with high energy demands and are directed by a variety of cues, whereas downstream phases often but not always occur by passive drift. Cyclic patterns of movement in such migrations are generally linked to seasonal environmental changes, in concert with the hormonal stage of the individuals involved, but they may be overlaid by did fluctuations. These features of migration are discussed in detail, with specific examples of the migratory capabilities and requirements of various species. Also discussed is the relevance of life-history stages to problems of fish passage over dams, weirs and other man-made obstructions in river channels. Of nearly 200 European fleshwater fish species, 67 are now considered to be threatened by a variety of human activities and major causes have been identified for 48 of these. Over half of these causes are associated with obstructions to migration pathways at dams and weirs, or other alterations in river channel features. There can be little doubt that migratory passageway problems are threatening a high proportion of European fleshwater fishes. Similar conditions are shown to affect many North and South American species, as well as those in the antipodes. If a major loss of freshwater fish biodiversity is to be avoided, more information must be gained rapidly on the migratory behaviour of freshwater fishes, and on effective means to facilitate the passage of young and adults in both upstream and downstream directions. Furthermore, attention must also be given to ensuring that appropriate habitat conditions for spawning, feeding and survival are available at either end of the migratory passageways used.Conference Fish Migration and Fish Bypass Channels Symp., Vienna (Austria), 24-27 Sep 1996 Fish Migration and Fish Bypasses, Fishing News Books, 1998, pp. 3-18 Price: pound sterling 65.

These changes have influenced the status of two acipenserid endemics to the area, the large Amu-Dar shovelnose, Pseudoscaphirhynchus kaufmanni, and the ship sturgeon, Acipenser nudiventris. The main biological characteristics of both species in the new environmental conditions are given. Previous unsuccessful attempts to introduce other acipenserid species into the area are also described. International cooperation is needed for saving the last surviving species representing the genus Pseudoscaphirhynchus. The only two other species of the same genus, P. fedtschenkoi, and P. hermanni, have already become victims of the Aral Sea catastrophe and are apparently extinct.

These experiments show that the flow from the Denil entering the pool diffuses as a surface jet, with an increased growth rate, possibly because of the circulation and turbulence in the pool. This diffusing jet impinges on the backwall and dives into the pool. The flow formation in the vicinity of the outflowing Denil appears to occur in a relatively small region. The energy dissipation in the pool is significant. To provide some resting areas for fish ascending the multiple Denils, it is necessary to provide some depth below the common invert of the two Denils. Some suggestions have been made for determining the size of these resting pools.Jul 1997 Issn 0733-9429 English Journal Article Water Resources Abstracts; ASFA 2: Ocean Technology Policy & Non-Living Resources"   Mitzner, L. 1978TMEvaluation of biological control of nuisance aquatic vegetation by grass carp4.Transactions of the American Fisheries Society 1071}135-14582Freshwater biological control; aquatic plants; fish catch statistics; sport fishing; Ctenopharyngodon idella; USA, Iowa, Red Haw L. weeds; herbivores; biomass; Pisces; primary production; introduced species; Cyprinidae; plant control Q1 08605 Sport fishing; Q1 08485 Species interactions: pests and control Grass carp Ctenopharyngodon idella introductions at Red Haw Lake, Iowa resulted in a decrease of aquatic macrophytes from 2438 g/m-2 in 1973 to 211 g/m-2 in 1976, with species of Potamogeton, Elodea, Ceratophyllum and Najas all controlled effectively. During 1974-1976 mean nitrites, nitrates, biological oxygen demand, and turbidity showed significant decreases, while alkalinity increased significantly from a mean of 115 mg/l in 1974 to 132 mg/l in 1976. Mean concentrations of organic and inorganic phosphates gradually increased during the investigation, but were not statistically different. Average primary production was nearly identical in 1974-1975 at about 2 g carbon/m-2 /day, but decreased significantly to 1.35 g carbon/mm-2 /day in 1976. Growth of stocked grass carp was rapidly increasing from a mean weight of 380 g in July, 1973 to 6847 g by October, 1976. Body condition ranged from 1.05-2.02 with average condition over 1.37 in October and 1.25-1.30 in January-February. Greatest population biomass was estimated in 1975 at 61 kg/hectare. Grass carp consumed all major plant groups at the lake with greatest selection for Najas and Potamogeton . Movement, behaviour and activity as determined by ultrasonic telemetry showed grass carp inhabited all areas of the lake, but overall there was a preference for shallow areas of the main lake with lesser selection for embayments. Most of the time grass carp were sedentary near weed beds with more rapid and extended movement in midwater. Normal swimming speed in midwater was 0.12-0.35 m/s with maximum speed of 1.46 m/s. Homing tendency was shown in 2 of 9 tagged fish.

Initial introduction occurred at Red Haw Lake in 1973 as part of a research investigation to study the feasibility of macrophyte control. Routine use of grass carp as a fisheries management technique in state-owned lakes commenced in 1975, and by 1979, the general public was permitted to buy and stock grass carp into public waters. Over 700 permits were issued to the private sector the first year the permitting system went into effect. Since 1973, grass carp have been stocked in over 40 state-owned lakes, and since 1979 approximately 2,000 private waters have been stocked. Stocking rate was initially 10 per acre (total lake surface), but more recently the recommended stocking rate was reduced to 5 or less per lake surface acre. Length of grass carp at stocking is recommended at >8 inches in waters containing largemouth bass. Partial control of vegetation by grass carp is rarely attained; normally there is an all-or-none response. At lakes with 100% control of vegetation, there are only minor changes in sport fish populations. For example, fisheries managers reported diminished bluegill recruitment at some lakes with 100% vegetation control. The most common complaint comes from bass anglers who perceive the "weedline" as being greatly reduced. Thus, according to anglers, bass are not nearly as vulnerable to hook and line at lakes with extensive macrophyte control. Overall, sportfishing has not been adversely impacted by grass carp introductions and in most cases catch has increased because of more available access to shore anglers fishing for bluegill and crappie. Grass carp reproduction has not been documented in Iowa waters; however, adults have been caught incidentally (60 lbs per pool) in commercial fishing gear in the Mississippi River bordering Iowa.TMConference 14.

W. Egginton, S. Taylor, S. E. Butler, P. J. "Wood, C. M. McDonald, D. G.l 0-521-49532-6 Cambridge University Press Cambridge (Uk)As thermal diffusion is an order of magnitude more rapid than molecular diffusion, it is clear that the same design features that make the gills of fish well suited for respiratory gas exchange from water (large surface area, active convection of water and blood at appropriate ventilation/perfusion ratios across a functional counter-current) also provide for very effective branchial heat exchange. This is reinforced by the relatively high heat capacity of water which is more than 3000 times that of air, so that for most fishes, and indeed all other water-breathing ectotherms, body temperature equilibrates rapidly to any change in environmental temperature. Consequently, in the absence of specific anatomical specialization to maintain thermal gradients, temperature throughout the body of fishes is in equilibrium with the environment to within a fraction of a degree. Thus, large changes in body temperature may be experienced: diurnally, by coastal fish subjected to tidal variations; or by vertically migrating pelagic species, particularly if they cross a thermocline; or seasonally by eurythermal temperate zone fish. Over evolutionary time, speciation of tropical and polar fishes has resulted in species with widely different thermal ranges within the accepted biological temperature range (between the freezing point of water and the temperature for protein denaturation), which do not overlap.s 1997Fish physiology; Gills; Heat balance; Thermoregulation; Body temperature Freshwater Q1 01346 Physiology, biochemistry, biophysicsrCAMBRIDGE UNIVERSITY PRESS, CAMBRIDGE (UK), 1997, pp. 105-133, Society of Experimental Biology Seminar Series , no. 61 English Book Monograph ASFA 1: Biological Sciences & Living Resources Theler, J.

Records of fishway utilization by the alewife, Alosa pseudoharengus and of the environmental variables were critically examined by time series autocorrelation and cross-correlation techniques. It was demonstrated that migratory activity was hormonic with a diurnal periodicity and was closely associated with incident solar radiation. Suggestions for an improved monitoring system and further analysis were made. h @i  - ZSTrans am fish soc. vol 101, no 4, p 583-594. 1972. illus. Water Resources Abstractsf0*Sandell, G.

Marked adult walleyes tend to home to spawning areas. Individual walleyes tend to return to the same open-water feeding areas in successive years. Movement of immature walleyes often differs from that of adults in the same waters. Intensity of walleye homing varies in separate waters and appears to be influenced by physical characteristics of the environment and strengthened by repeated migrations. River and wind currents commonly move walleye eggs and fry great distances from the site of egg deposition before fry are sufficiently developed to commence feeding. This makes natal conditioning to spawning areas unlikely.  0 ^WConference Presented at : Symposium on Selected Coolwater Fishes of North America, St. Paul, MN (USA), 7 Mar 1978 In : Selected coolwater fishes of North America, Am.

Current design practices are summarized based on the results of an international survey and interviews with agency personnel and consultants. The fluid mechanics and hydraulics of fishway systems are discussed. Fishways (or fishpasses) can be classified in two ways: (1) on the basis of the method of water control (chutes, steps (ladders), or slots); and (2) on the basis of the degree and type of water control. This degree of control ranges from a natural waterfall to a totally artificial environment at a hatchery. Systematic procedures for analyzing fishways based on their configuration, species, and hydraulics are presented. Discussions of fish capabilities, energy expenditure, attraction flow, stress and other factors are included.REP. U.S. DEP. ENERGY., 1986, 180 pp NTIS Order No.: DE86011445/GAR.

Initial costs or practicality have limited the development of some innovative structures. Conservative design stems from (1) a lack of hard data on fish swimming and leaping capabilities, (2) a lack of integration of fluid mechanics with fish capabilities, and (3) designs based on fish responses rather than on stimuli. This paper summarizes the state of the art in fishway design and the development of several more efficient fishway designs. The efficiencies are derived from a combination of more expeditious fish passage, maximization of the instream flow operating range, and less costly construction. When competing or conflicting water uses are present, such as in the development of small hydropower, the minimization of water use in the fishway can become a fourth consideration.Conference 1. Int.

The construction of the Yacyreta Dam (Argentina-Paraguay) started in December, 1983, level with km 1460 of the Parana River, in one of the richest regions of Argentina as regards to the size of fish populations, the number of species and the specimens length. The aims of the present thesis are: 1) to establish the variations in the fish community structure downstream Yacyreta Dam; and 2) to establish the structure of fish community in the left and right elevators. To propose handling rules in order to improve the fishway efficiency. Fieldworks were carried out monthly, from October 3, 1994, until July 17, 1996, and consisted in: 1) acoustic evaluation of fish abundance and control captures downstream the dam; and 2) fish elevatoris census. The studies allowed to establish that, the total number of fish tranferred in 1995 reached 1,766,924, with a monthly average of 176,692 fish (n=10). The total biomass transferred in 1995 reached 982 metric tons (mt), with a monthly average of 98.6 mt. The right elevator was the most efficient, as regards to the number and weight of fish transferred, due to its nearness to the bank and because the right turbines were not in operation. During the whole period studied, this fish elevator transferred 29% more fish and 42% more biomass. A seasonal variation in the abundance of fish was noticed in the elevators, showing maxima in spring and summer which coincided with the results of fishing control. Pimelodus clarias was the most abundant species in the fish elevator, reaching 76.6% followed by Pterodoras granulosus with 11.8%. P. clarias was the only species having almost constant presence in the fish elevator during the whole year; Megalancistrus gigas was also present but to a lesser degree. The species considered as migratory are predominant in the system from October until January, and they are the following ones: Pseudoplatystoma coruscans, P.fasciatum, Paulicea lutkeni, Pseudopimelodus zungaro, Oxydoras kneri, Ptedoras granulosus, Rhinodoras d'orbignyi, Prochilodus lineatus, Salminus maxillosus, Leporinus obtusidens and Raphiodon vulpinus. Fish elevators were highly selective for small and very big sizes, favouring the transfer of fish whose length vary between 35 and 55 mm. Fish elevators allowed the passing of 5 cohorts for L.obtusidens, O.kneri, P.clarias; of 4 for P.granulosus, P.lineatus; of 3 for M.gigas, R.d'orbingyi, S.maxillosus, P.labrosus, of 2 for Sorubim lima and of 1 for Schizodon borelli. The size and average of transferred fish increases in spring and summer, associated to migratory species. The average annual weight (in 1995) reached 0.66 kg. The highest specific abundance was noticed in the early morning hours and in the late afternoon hours. Considering the daily cycles of system use, 3 groups of species were identified: diurnal species (M.gigas, L.obtusidens, R.d'orbignyi); nocturnal species (P.clarias, P.coruscans, P.granulosus) and diurnal-nocturnal species (S.borelli, O.kneri, S.lima, S.maxillosus, P.lineatus). The highest estimates of the total number of fish obtained by means of acoustic evaluations in the area under consideration took place between March and April. As an average, they represent 1,014 and 1,207 f/ha with 107 and 214 FPEU (Fish Per Effort Unit) values. The highest abundance of fish and species takes place between October and November (in spring), while the lowest, in both cases, happens mainly in autumn. In the periods of highest abundance, the total number of fish would reach 2,000,000.K   , A N X   w                      0  2  F  K  ]    )  +  2  4  =  H  T  V  `  k  r  t                    :  A  C  O  Q  ]  s  |  ~                           LFOriginal Title Evaluacion del impacto de la represa Yacyreta en la comunidad de peces.

To minimize the energy cost of migration, when confronted with currents, fish must optimize both the mean swimming speed and the degree to which swimming speed is altered in response to changes in current velocity. The optimum swimming speed in a current is Uo + 1/b where Uo = mean current speed and b is a constant in the equation E(t) = a e-bW(t) describing the relationship between specific energy expenditure per unit time (E(t) and swimming speed W(t). In a variable current, such as might occur in estuaries and coastal areas, energy expenditure is minimized when these variations are ignored and a constant speed through the water is maintained. This is true even in conditions where occasional retrograde motion over the botton may occur. The added energy costs of swimming at mean speeds or of varying swimming speeds in response to changes in current velocity are rigorously defined. Predictions of the model are in general agreement with empirical data on fish swimming behavior. k @l z @{    nhUsing Smart Source Parsing (1980) English Journal Article ASFA 1: Biological Sciences & Living Resources$Tsuyuki, H.

Over 10,000 channel catfish were tagged from the lower Wisconsin River and adjacent waters of the Upper Mississippi River during the 3-year sampling period. Data on movements were obtained from study recaptures and through tag returns and harvest information provided by sport anglers and commercial fishers. Channel catfish occupied relatively small home ranges during summer, migrated downstream to the upper Mississippi River in autumn, then migrated back up the Wisconsin River in spring to spawn and to occupy the same summer home sites they had used in previous summers. Fish size was a factor in the degree of fidelity to summer home sites, with larger fish showing greater fidelity.

Now many other purposes are cited, including flood control, industrial uses, navigation, fisheries, and recreation and leisure. The ecological impact of river regulation schemes is considered, including a conceptual framework for the evaluation of that impact, tools available for mitigation of effects and even enhancement of river ecosystems, and problems of implementing policies for the ecological management of regulated rivers. Regulation of the Zambezi River is emphasized as an example. Assessment of the environmental impact of river regulation requires consideration of spatial dimensions (global and catchment scales) and the temporal dimension. Three approaches to potentially harmful river regulation schemes have been recognized: (1) preserving a portion of wild river; (2) secondary regulation, in which additional structural measures and special operation rules are employed; or (3) compensation schemes (e.g., fish ponds to compensate for lost fish). Of these, secondary regulation should be considered first. Measures available include flow modifications, water quality control, channel design and maintenance, fish passage, biological alternatives (e.g., stocking), and controls on human activities. It has been argued that in developing nations the pressures for agricultural development should take precedence over concerns about environmental impacts from river regulation. This view does not recognize that sustainable development requires environmentally sound management. As illustrated by the approach taken in Zambia , development activities and environmental management can be integrated. Alternatives in Regulated River Management.

In 1946 small numbers of young skipjacks were collected from five sites on the Illinois River between Flint Creek and the mouth of the Illinois River near Gore. The skipjack herring also has been collected in the tailwaters of the Red River below Lake Texoma. The species was not found in the pre-impoundment surveys conducted by the Oklahoma Department of Wildlife Conservation (ODWC) of the Arkansas and Cimarron rivers in the area of the proposed Lake Keystone in 1961. Annual fish collections by ODWC using gill netting, electrofishing, and seining have produced the following numbers of skipjack from mainstream reservoirs of the Arkansas River: from Robert S. Kerr Lake, 1 in 1979, 28 in 1980, none in 1981, 9 in 1982, 12 in 1983, 31 in 1984, 3 in 1985 , 8 in 1986, 45 in 1988, and 18 in 1990. From Webbers Falls Lake , ODWC obtained 15 in 1981, 2 in 1982, 7 in 1983, 1 in 1985, and 27 in 1988, and from W. D. Mayo Lake, 29 in 1987 and 7 in 1988. The skipjack herring appears to be more abundant today then before impoundment of the Arkansas River in the 1970s. The upstream distribution is now limited to the Arkansas River below the Keystone Dam. The lakes of the Arkansas navigational system have provided a desirable habitat and may account for the recent increases in the skipjack.

The purpose of this study was to identify spawning habitat for walleyes Stizostedion vitreum so those areas could be afforded protection from future alterations. Radiotelemetry, egg collections, and the presence of sexually mature fish were used to identify walleye spawning sites in Pool 13 of the upper Mississippi River. Over 2,000 walleye eggs were collected in drift nets at two sites from 1983 through 1986. Substrates at spawning sites comprised sand, gravel, and cobble and included a freshwater mussel bed at one location. Water depths at spawning sites ranged from 0.6 to 6.1 m, and the current velocity ranged from 42.7 to 115.8 cm/s during 1986. Most walleye eggs were collected in April within 2 weeks of peak discharges when water temperatures were 8.3-12.2 degree C.

Salmon carcasses provide nutrients and energy to biota within aquatic and terrestrial ecosystems through various pathways. In this paper we review and synthesize the growing number of studies documenting this process in different localities. We also discuss the implications for maintaining the nutrient feedback system. Our findings show that future management will need to view spawning salmon and their carcasses as important habitat components for sustaining the production of fish as well as other salmon-dependent species within watersheds.sOct 1999 Issn 0363-2415 English Journal Article ASFA 1: Biological Sciences & Living Resources; ASFA 3: Aquatic Pollution & Environmental Quality; Ecology Abstracts; Water Resources Abstractse$Chamani, M.

Fully developed aerated flow on a stepped spillway can be divided into lower and upper regions, similar to those for self-aerated flow in steep chutes. The air concentration distributions in these two regions agree with the equations developed by Straub and Anderson for flow in steep chutes. It was found that the depth at which the air concentration is equal to 90% can be considered as the depth of aerated flow on stepped spillways. In the lower region, the velocity profiles were described by the Karman-Prandtl equation for rough turbulent flow when an equivalent bed roughness was used. A correlation was developed for the skin friction coefficient to predict the Reynolds shear stress at the virtual bed of the stepped spillway. It was found that the relative energy loss in the stepped spillway is in the range of 48-63%. It was also found that the mean air concentration on a stepped spillway is larger than that in a corresponding chute.  @ Apr 1999 Issn 0733-9429 English Journal Article Water Resources Abstracts; ASFA 2: Ocean Technology Policy & Non-Living ResourcesuN Nb Ransom, B.

The mortality to fish passing through hydropower dams has been variously estimated at 2-30%. Many of the power producers applying for licenses in the USA and elsewhere have been required to evaluate the impact their facilities have on fish. Entrainment studies are potentially expensive, labor intensive, and can effect project operations. Estimates of fish entrainment may be required 24 hour/day for up to 12 months, with periodic evaluations of fish survivability through turbine units. Underwater acoustics (sonar) provides one method of obtaining these data that has been accepted by many government fisheries agencies (Federal Energy Regulatory Commission 1987). Fixed-location hydroacoustic techniques have proved effective at documenting and quantify the abundance and behavior of fish passing through hydropower dams, and in reservoirs. In the last 15 years, hundreds of hydroacoustic evaluations of entrainment at hydropower dams have been conducted in the USA.d^Conference International Symposium of the North American Lake Management Society, Seattle, WA (USA), 29 Nov-4 Dec 1993 LAKE RESERVOIR MANAGE., 1994, vol. 9, no. 1, pp. 163-169 Issn 0743-8141 English Book Monograph; Conference Water Resources Abstracts; ASFA 3: Aquatic Pollution & Environmental Quality; ASFA 1: Biological Sciences & Living Resources0)Ransom, B.

Accompanying this reliance has been an interest in comparing hydroacoustic estimates of smolt passage with net catch estimates of fish passage, single-beam hydroacoustic techniques were used. The correlation between hydroacoustic and net catch estimates of smolt passage into the sluiceway at Ice Harbor Dam was statistically significant. Rocky Reach Dam hydroacoustic and fyke net catch vertical distributions were very similar. At Lower Granite Dam, the correlation between net catch estimates and hydroacoustic estimates of smolt passage was statistically significant. At Wanapum Dam in 1994, there was significant correlation between net catch and hydroacoustic estimates of smolt passage, and there was no statistically significant difference between the paired estimates. From 1991 to 1994, there was a significant correlation between mean hydroacoustic and net catch estimates of in-turbine diversion screen fish guidance efficiency, with no significant difference between the paired estimates.n   $Conference ICES Int.

The immigration of fishes into the MFK is dependent on the effectiveness of fish bypass channels at several weirs. To investigate the efficiency of the lower most fishway we estimated the population densities along the MFK-system and below the weirs using electrofishing. In addition, the movements of 15 radio-tagged pike-perch at the fishway were observed. Although more than 57 000 fishes of 35 species passed the bypass channel, pike-perch Stizostedion lucioperca were under-represented in the fishway traps compared to their occurrence in the channel. The average daily movement of radio-tagged pike-perch was 108 m (range 6-333 m) and the maximum observed daily movement was 1050 m. The entrance to the bypass channel (280 m below the weir, and 100 m above the release site) was approached a number of times by 6 tagged fish, though none of them entered the bypass channel during the period of tracking. We conclude that although pike-perch migrate actively they do not utilise the bypass channel as much as most fish species of the MFK. Therefore the weir still represents a bottleneck for the immigration of pike-perch into the MFK. h  Conference 2.

Thus, efficient use of available energy is of great importance and various adaptations of morphology and behavior have resulted. These are especially significant for diadromous species, which encounter large variations in buoyancy, salinity, temperature, and flow conditions during their life cycles, which include large-scale migrations. A mathematical approach to fish migratory adaptations is utilized to analyze observed behavioral patterns and to predict effects of changing environmental pressures. The study is based on the hydrodynamical and mechanical principles of fish locomotion, feeding, and predator-prey interactions. Existing work is reviewed with the goal of identifying areas of future observational and theoretical research applicable to the understanding of the behavioral strategies of these species, many of which are commercially important.Conference 1.

Glochidia were encysted on 4.1% of the 2,510 fish of 43 species examined. Twenty-five fish species in 11 families were infested; 14 of these species are not known to be hosts of any of the 27 mussel species (Unionidae) occurring in the Barren River. Amblemine glochidia occurred on 19 species of fish. Eight species of fish were infested with anodontine glochidia, while lampsiline glochidia occurred on only five species. Differences in the degree of host specificity were striking among the Ambleminae. Glochidia of Amblema plicata (Say, 1817) occurred on 12 species of fish, whereas those of Quadrula pustulosa (I. Lea, 1831) were found only on channel catfish [Ictalurus punctatus (Rafinesque, 1818)]. Overlap in host fishes occurred between the Ambleminae and the other subfamilies, but not between the Anodontinae and Lampsilinae. Potential new hosts are identified for Lasmigona complanata (Barnes, 1823), Lasmigona costata (Rafinesque, 1820), Megalonaias nervosa (Rafinesque, 1820), A. plicata, and Pleurobema spp. d s           ( = G M [ tm1995 Issn 0740-2783 English Journal Article ASFA 1: Biological Sciences & Living Resources; Ecology AbstractsNWelcomme, R.

The author shows how the various activities occurring in river basins can influence the fish communities inhabiting them. The book is divided into six parts, the first of which is a general introduction outlining previous work done in the field. This is followed by a substantial section on the environment, dealing with the physical and chemical composition of rivers and their floodplains. It also summarises data on the living elements of the system other than fish. A section on fish discusses the adaptations they show for life in a fluctuating environment, and examines the effects of seasonal alternations of flood and dry phases on feeding, growth, reproduction, mortality and the general dynamics of the community. The fishery is treated in a fourth section, which considers the specialisation of fishermen and their gear to the river environment. It also reviews the state of exploitation of some of the main rivers of the world, and examines how catch is related to such variables as water regime and fisherman density. The fifth section explores the relationships of the fish community to other activities in the river basin. The concluding chapter discusses the stages through which fish communities and fisheries pass as the environment is altered by basin development.uPubl. by: Longman; London (UK)., 1979., 317 p.

Though several investigators have attempted to define swimming capabilites of fish, it does not appear that the swimming requirements for fish to pass through culverts and other fish passage structures have been properly analyzed and defined. This paper defines and analyzes the forces which fish are confronted with in entering and passing through barrels of sloping culverts flowing full and as open channels.n Behlke, C.

The Illinois Waterway System (IWS) connects the Great Lakes and Mississippi River basins and facilitated the spread of another exotic nuisance species, the zebra mussel Dreissena polymorpha, to other environmentally sensitive drainages of interior North America earlier this decade. We surveyed the distribution of round goby in a portion of the IWS near metropolitan Chicago in autumn 1996 with traps, seines, trawls, set lines, and by angling. A total of 61 round goby were captured in the Little Calumet River in south Chicago at locations upstream of river mile 321.4 (12 miles inland from Lake Michigan). No round goby were captured at sites in connecting channels downstream (i.e., further inland) of this point as far away as Joliet (river mile 283). Bottom trawling, particularly over rocky substrates, was the most successful means of capturing round goby and accounted for 87% of the total catch. Goby captured by trawling were significantly smaller than those captured by other gears and significantly smaller goby were captured at the sampling site furthest upstream. The length frequency distribution of the round goby we captured suggested the presence of fish from the three most recent year classes (1994-1996). The rocky substrate preferred by round goby may be less common in a short reach of the Little Calumet River downstream of river mile 321. Despite this potential habitat deficiency, population growth and human interventions are soon likely to expand the range of the round goby in the IWS. 2 I   &Conference Int.

The survival of test and control fish in 1981 was determined by comparing their rate of downstream movement with that of 28 prekilled fish. The survival of test fish in 1982 was determined as in 1981 by using nine prekilled fish. At full power generation, the mean percent turbine-induced mortality at 2 h (95% confidence interval in parentheses) was 11.8 (3.8-18.0) in 1981 ad 13.7 (1.9-22.5) in 1982.

Eight of 13 loci examined were polymorphic in at least one population with an average heterozygosity at all loci and across all populations of 0.14. The R sub(st) and F sub(st) values indicated differentiation among populations (R sub(st) = 0.61, F sub(st)). Although microsatellite variation found in northern pike was much lower than that found in sympatric and other fish species, the allozymes and mitochondrial DNA. UPGMA-clustering phenograms were generated based on five genetic distance measures with 2000 bootstrap replicates per measure. All measures yielded highly repeatable population structure between continents (supporting values = 92.4-100%) and within Finland (42.3-98%). Four measures differentiated the Alaskan population and Young Lake (Great Lakes drainage) from other North American populations (56.6-87.7%). Relationships among other North Central United States populations were unclear, as indicated by low supporting values. Results support the hypotheses of one refugium in the North Central United States and more than one refugium in Europe during the last glaciation. a l `Z2000 Issn 0706-652x English Journal Article ASFA 1: Biological Sciences & Living Resources602,North, J.

The study also evaluated effects of hydroelectric dams on white sturgeon populations. Differences in catch per setline-day indicated that white sturgeon densities were greatest in Bonneville Reservoir and least in John Day Reservoir. White sturgeon concentrated in tailraces of dams and density generally declined downstream through each reservoir. Distribution within each reservoir varied with sampling month and were related, in part, to temperature. Most fish were caught at depths from 10 to 30 m. Tagged fish were often recaptured in locations other than those where originally marked. Some fish were recaptured as far as 152 km from where released. Individual fish frequently traveled the length of a reservoir, but were seldom recaptured in another reservoir. Dams restrict white sturgeon movements, may limit populations in some reservoirs, and concentrate fish immediately downstream, potentially increasing their vulnerability to exploitation. To optimize these fisheries, resource managers must recognize differences among reservoirs and employ regulatory schemes specific to each.h G ^ 1993 Issn 0029-344x English Journal Article Ecology Abstracts; Animal Behavior Abstracts; ASFA 3: Aquatic Pollution & Environmental Quality; ASFA 1: Biological Sciences & Living ResourcesF O Parasiewicz1998 Parasiewicz1998 Park19941 Parker19939 Parsons1975!

In the first two fishways, flow conditions, i.e. flow velocity, drop between pools and rate of energy dissipation per unit of volume, were studied in relation to tailwater and headwater fluctuations. The main purpose of these studies was to optimize the position of entrances and determine the discharge needed to provide adequate attraction at these sites. The modeling resulted in design changes that should improve fish passage.Original Title Utilisation des modeles reduits pour l'etude des dispositifs de franchissement sur les trands cours d'eau Conference Actes du Colloque Franco-Quebecois sur la Restauration des Rivieres a Saumons, Bergerac (France), 28 May 1985 (RESTORATION OF SALMON RIVERS.)., LA RESTAURATION DES RIVIERES A SAUMONS. , 1987, pp. 149-157, COLL.

These dams were non-navigational (without locks), lacked fish ladders, and varied in height from 1 to 17.7 m. Both species were restricted in their distribution to the river downstream of the dams. This suggests that the host fish(es) of these species was unable to move upstream of these obstacles. Both unionoids are believed to parasitize the freshwater drum Aplodinotus grunniens. Several endangered unionoid species also may use this fish, or other dam-limited fishes, as hosts. Dams, even lowhead structures, may contribute to the overall depletion of unionoids by artificially restricting their distributions and isolating populations from each other. Management practices for endangered fishes and mussels must take into account these physical obstacles.s 7 H _ o I ^ 1996 Issn 0006-3207 English Journal Article Ecology Abstracts; ASFA 3: Aquatic Pollution & Environmental Quality; Water Resources Abstractsa rjWelcomme, R.

In both cases, slotted weirs were modified so that a better head loss distribution was obtained. In addition, the diffusers were modified to produce acceptable exit face velocity distributions. At Turners Falls, the fish entrance was modified to produce velocity conditions known to be acceptable to the two migrating species of fish, Atlantic salmon and shad. At Vernon Dam, flow conditions were optimized at the fish exit and attraction water intake. Modeling of these fishways has resulted in design changes that should improve fish passage and minimize water consumption.White, M. M.

Freshwater Q1 01582 Fish culture; Q3 01582 Fish culturenAn electrophoretic survey of populations of walleye Stizostedion vitreum and sauger S. canadense from the Ohio River was conducted to determine the patterns of genetic variation, population structuring, and the degree of hybridization between these two species and their stocked F1 hybrid, the saugeye (female walleye x male sauger). Thirty-six presumptive structural loci were surveyed from the eye, liver, and muscle tissue of 500 sauger from nine locations and 222 walleyes from seven locations. Levels of variation in sauger were low and suggested limited population differentiation along the river. Levels of variation among walleye populations suggested a significant degree of population differentiation; however, no clear pattern of differentiation was observed. Two polymorphisms, not previously observed in walleye populations, are shared with sauger, suggesting past hybridization events or geographically unique alleles. Recombinant genotypes were detected in samples from three Ohio River pools, confirming that hybrid reproduction has occurred. These three pools are consecutively affected by one major river and four smaller watersheds that have received large numbers of stocked saugeyes. If maintaining the genetic integrity of the parental species is a concern, our data strongly suggest that saugeye should not be stocked where self-sustaining parental populations occur. 4 H T `  @ Conference 15.

Some introductions occurred in historical times, but the rate of movement of species between countries has accelerated since 1900. The majority of introductions have been carried out in support of aquaculture, although sport and improvement of wild fish stocks have also been significant motives. A large number of introductions have occurred through accidental escape or transmission between countries. Most introductions have proved benign in that they have had no detectable influence on native fish communities or have contributed significantly to aquaculture or capture fishery yield. A small proportion of introductions have proved ecologically undesirable, and these have arisen mainly either from species capable of producing stunted populations or from predatory species which have damaged indigenous species.rF?Conference Introductions and Transfers of Aquatic Species: ICES Marine Science Symp., Halifax, N.S.

Twenty-five species were collected in the North Fork above Altus Dam, compared to 33 in the Salt Fork and 34 in the North Fork below the dam. The speckled chub Macrhybopsis (formerly Hybopsis) aestivalis and the chub shiner Notropis potteri were absent in the North Fork above Altus Dam but fairly common in similar streams elsewhere in the area.

The structure and magnitude of genetic diversity of natural populations serves to buffer these fishes against environmental variation and should be maintained. Modern molecular biological techniques provide the ability to sensitively characterize and quantify the extent of genetic variation in natural populations. We provide a summary of those problems in sturgeon population biology that are amenable to investigation with DNA approaches, and their applications to date. These have included genetic identification and discrimination of taxa, identification of hybrids, stock identification, mixed-stock analysis, and estimation of gene flow and homing fidelity. To date, almost all studies have been restricted to North America fauna. Improvements to these technologies, including nondestructive sampling, should permit more widespread application of molecular approaches to problems of acipenserform conservation. We suggest that the use of more sensitive molecular tools such as analyses of hypervariable repetitive and non-coding single copy nuclear DNA may assist management even in those taxa which exhibit overall low levels of genetic diversity.1997 Issn 0378-1909 English Journal Article; Conference ASFA 1: Biological Sciences & Living Resources; ASFA 3: Aquatic Pollution & Environmental Quality "Witherell, D.

A systemic overview is given of current operating plans at dams on the UMR and historical data are analysed to determine how well the operating plans are being met. Water level elevations at all 27 dams are regulated as a function of discharge, although plans are specific for each dam. The management objective is to maintain a target water level at specific locations (control point) in each impoundment over specific ranges of discharge. The target water level and control point may change as discharge changes in each impoundment. In some of the impoundments water regulation causes drawdowns below the elevation for which the dams were planned, and at other dams no drawdown occurs. During the navigation seasons of 1980 to 1990, water levels were within their target window for an average of 72.5% of the time for 25 dams analysed. Difficulties in meeting targets are caused by winds, local rainfall events, ice dams and rapidly fluctuating discharges from tributaries with upstream reservoirs used for peaking hydropower.D=Conference Conference 'Sustaining the Ecological Integrity of Large Floodplain Rivers: Application of Ecological Knowledge to River Management', La Crosse, WI (USA), 12-15 Jul 1994 Oct 1995 Issn 0886-9375 English Journal Article; Conference Water Resources Abstracts; ASFA 3: Aquatic Pollution & Environmental Quality \0ff Frost, S.

There is a rich early record of natural history studies by Bartram, Michaux, Lesueur, Rafinesque and others. The navigational use of the river began with snag pulling and has progressed to modern high-lift dams. Flood control, navigational use of tributaries, and canal-building have been water resource development projects of the past. Early industries that developed around the availability and abundance of coal, oil, natural gas, salt, iron ore, timber, and clay in the valley ultimately led to the more recent pottery, iron and steel, chemical, and power generation industries along the river and its tributaries. There were also major horticultural developments of apple orchards, wine vineyards, and even silk worm farms along the river and a modest button industry from the mussels in the river itself. The pollution of the Ohio River has been a concern for decades, and the involvement of the federal government and the establishment of interstate compacts have led to the development of significant understanding of the science of water pollution and to the general improvement of the river's water quality..xqOhio Journal of Science OJSCA9 Vol. 89, No. 5, p 143-152, December 1989. 8 fig, 43 ref.

The impacts of these on three biological descriptors of the hydrosystem (benthic invertebrates, fish communities and aquatic birds) have been studied. A reduction in the morphological diversity of the regulated hydrosystem has caused a reduction in biological diversity. This system has become a slow potamic system as a consequence of the more uniform environmental conditions: the benthic macroinvertebrate fauna has become eurytopic and pollution tolerant, with very localized potamic species; fish communities are dominated by limnophilic cyprinids; and water bird communities are limited by the absence of typical species of fluvial areas, such as terns.1992 Issn 0886-9375 English Journal Article; Review ASFA 3: Aquatic Pollution & Environmental Quality; ASFA 1: Biological Sciences & Living Resources; Ecology Abstracts; Pollution AbstractsAf.(!Woody, C.A.

We found M. nervosa to be a late tachytictic breeder. Female marsupia contained eggs or glochidia primarily from August (17 oC) through October (9 oC). Males were mature from July through October. Most females released their glochidia in October. Only one female was gravid in November (3 oC). Most mussels were mature at 8 years of age and then had an estimated average size of 68mm (shell height). Only 8% of the individuals <= 4 years of age showed any degree of reproductive development, while > 90% of age 5 and older individuals had recognizable reproductive material present. In host specificity studies, we verified three species of fish as hosts for the glochidia stage. Green sunfish Lepomis cyanellus, black bullhead Ictalurus melas, and channel catfish Ictalurus punctatus produced juveniles after 26-28 days at 17 oC. White suckers Catostomus commersoni and yellow perch Perca flavescens retained glochidia from 23 up to 26 days, but no juveniles were produced.

A baffle wall is used to produce a stable deflected surface jet, thereby deflecting the high-velocity supercritical stream away from the bed to the surface. Based on a series of experiments, a diagram was developed that predicts the conditions under which such a surface jet would be produced. A second series of experiments were performed to study the characteristics of the deflected jet, as it travels upward first as a curved turbulent jet to eventually become a turbulent surface jet. The decay of the maximum velocity in the deflected as well as the surface jet was studied and compared with that of a plane turbulent wall jet that is a model for deeply submerged jumps.rhb1995 Issn 0733-9429 English Journal Article ASFA 2: Ocean Technology Policy & Non-Living Resources*#Wu, S.

The flow at the slot could be treated as a plane jet, but there are a number of differences from the plane jet. It was found that for a slope of 5%, the main flow travels from one slot to the next through the pool as a 2D curved jet with two recirculation regions - one on each side. For slopes of 10 and 20%, the main flow is 3D. Water flows toward the side wall between the long baffles near the bed and piles up along the sidewall; part of the flow rises to the surface and then travels to the outlet. The decay of longitudinal velocity in the pool is much larger than that of the plane jet. The volume averaged velocity head of the water in the pool was found to be similar to 12% of Delta h, the head drop per pool. The volume of the recirculation region between the short baffles was similar to 28% of the volume of the pool for all three slopes and all discharges whereas the corresponding volume of the horizontal eddy just downstream of the long baffles for the two larger slopes was similar to 10%. The relative volume of the two recirculation regions was similar to 73% for the 5% slope and similar to 38% for the 10 and 20% slopes.2Apr 1999 Issn 0733-9429 English Journal Article Water Resources Abstracts; ASFA 1: Biological Sciences & Living Resources; ASFA 2: Ocean Technology Policy & Non-Living ResourcesN6/Measuring the velocity of water at fish laddersp Ylinaerae, T.s Vesitalous323, 31-34lZTA more versatile apparatus than the propeller current meter has been tested for measuring water velocity in the course of research into the swimming behaviour of migratory fish.

Knowledge of movements is important for defining the spatial scales for effectively managing paddlefish stocks and for evaluating the effects of habitat alterations, such as dams, on paddlefish. In 1994 and 1995, we evaluated movement and habitat use of paddlefish with radiotelemetry in Pools 5A and 8 of the Upper Mississippi River, and in the Wisconsin and Chippewa Rivers. Paddlefish were tagged in the lower Black River (Pool 8, upper Mississippi River), in Pool 5A of the upper Mississippi River, near Caryville in the Chippewa River, and in the Wisconsin River below Prairie du Sac dam. Many remained at these locations throughout the year. In spring, 1995 about half of the radiotagged paddlefish moved downstream up to 90 km in the Wisconsin and Chippewa Rivers, presumably for spawning activities. Paddlefish in Pool 8 remained in the upper portion of the pool throughout spring. Paddlefish that moved downstream during spring returned in early summer. Diel studies conducted in Pool 8 during spring 1995 indicated greater movement at night (mean = 525 m/h) as compared to day (mean = 212 m/h), but use of habitat types did not differ among day, night, or crepuscular periods. While most paddlefish did not move great distances during summer, a few fish moved between 150 and 250 km from tributaries into the upper Mississippi River. In the lower portion of the tributaries rivers, which do not contain dams, paddlefish moved large distances upstream and downstream. In the upper Mississippi River, dams appear to be effective barriers to upstream paddlefish movement. Research studies are continuing to monitor seasonal patterns of habitat use and movement..

We radio-tracked five paddlefish during three randomly chosen 24-h periods each month in May, August, and October 1995. Paddlefish were located by boat one to three times every 3 h during each 24-h period. At each location, geographic coordinates were determined with a global positioning system receiver using the Precise Positioning Service, and depth was measured with a depth sounder. Location coordinates were plotted with ARC/INFO software on a Geographic Information System land-water coverage. Movement distances were calculated as the linear distance between sequential locations. Radio-tagged paddlefish usually remained in a secondary channel that had low current velocity during all seasons, whereas main channel, main channel border, tailwater, and backwater habitats were seldom used. Paddlefish strongly selected areas that were deep; about 62% of paddlefish locations were in areas with more than 6 m of depth, although this habitat constituted only 14.5% of the total study area. However, paddlefish used significantly shallower areas during the night than during the day. Paddlefish moved significantly larger distances at night than during the day in spring and fall, but differences in movement among diel periods during summer were not significant. Our research suggests that radiotelemetry studies that need to determine depth use or movement of paddlefish during small time scales may need to incorporate a diel component. However, study objectives to determine use of general habitat types by radio-marked paddlefish can be adequately met by tracking during the day. 7 H Feb 1999 Issn 0275-5947 English Journal Article ASFA 1: Biological Sciences & Living Resources; Ecology Abstracts; Water Resources Abstracts4-Zimpfer, S.

Catches were greatest in the lower Red River; peaks were associated with increasing river stage, current speeds of 1.2-2.2 m/s, water temperatures of 23.5-28.2 oC, pH values of 7.2-7.7, dissolved oxygen concentrations of 4.0-7.6 mg/L, and secci disc readings of 1-9 cm. Catches were least near navigation locks and dams on the Ouachita River, where flows were 0.6 cm/s or less when water temperatures were optimum. Intermediate catches of larvae were taken from the Atchafalaya River and the Mississippi River Diversion Channel. Major spawning areas in the Mississippi and Red rivers were located in or near Arkansas, where grass carp were first released. The occurrences of juveniles and adults in commercial catches from the Black, Mississippi, and Red rivers, and of newly hatched larvae in the backwaters of the Atchafalaya River basin, suggest that grass carp are successfully recruited to fish stocks of the lower Mississippi Valley.5  ,    Conference 10.

On regulated rivers such as the Mississippi, water level and velocity fluctuations are caused by natural hydrologic events that change river discharge and by operation of water control structures. The Upper Mississippi River System (UMRS) includes the Mississippi River upstream of the mouth of the Ohio River at Cairo, Illinois, to Minneapolis, Minnesota; the Illinois River; and navigable portions of the Kaskaskia, Black, St. Croix, and Minnesota Rivers. River regulation greatly influences habitat conditions in the river. Changes to the present system of river regulation could improve habitat conditions and ecological productivity of the UMRS. Any modifications to the existing regulation plans must be compatible with constraints on operation. The purpose of the report is to identify the constraints on regulation of Lock and Dam 9 in the Upper Mississippi River 9-foot channel navigation system.vID No: EMTC93S012, , 1993, 100 pp NTIS Order No.: PB94102233XSP.

Brown trout were formerly known to migrate long distances, but several dams and river regulations have made migration difficult, as fishways constructed at the dams are not efficient. To compensate for the resultant reduction in brown trout, the river system has been stocked with hatchery fish reared from native brown trout. Genetic analysis by enzyme electrophoresis was conducted to monitor possible genetic effects on native fish. Brown trout were obtained from a fishway at Lopet in the South Rena River, and from a section at Deset, 16 km upstream of the fishway. One sample was taken from a cohort of first generation hatchery fish, based on only six spawning fish collected in the fishway, and one sample was taken from the second hatchery generation, bred from a mixture of two cohorts of first generation hatchery fish. The pooled broodstock of these two first generation cohorts numbered five females and five males. Eight samples were taken from second-, third- and fourth-order streams containing populations differing in size and degree of isolation. Tissue samples taken from eye, liver and muscle were analyzed using starch gel electrophoresis for protein polymorphism to determine genetic population structures. Allele frequencies, heterozygosity and polymorphism were compared. The fraction of heterozygosity ranged from 3.3 to 13.5% in the wild populations, and the lowest fraction was found in the most isolated population. Heterozygosity was 8.0% in the first generation of hatchery reared fish and 7.3% in the second generation. The number of detected polymorphic loci ranged from one to seven, with a mean of 4.5, in wild populations, but was three in the first generation and four in the second generation of hatchery fish. Polymorphism seemed to be lost at three loci in the first generation, but one locus was restored in the second generation, probably due to breeding with another hatchery cohort.    Conference 7.

The method was first evaluated in the field using underwater video cameras (stereocinematographic method, SCG) to estimate accurate fish swimming speeds. The mean and distribution of swimming speeds of 15-cm brook trout (Salvelinus fontinalis) obtained by the two methods were not statistically different (average 17.8 cm s-1 with split-beam and 18.6 cm s-1 with SCG). We then used the split-beam technique to measure swimming performance in situ for fish assumed to be yellow perch (Perca flavescens) and alewives (Alosa pseudoharengus) in two lakes in New York State, USA. The measured swimming speeds ranged from 0.5 to 6 body length (BL) per second for juvenile and adult fish. Other laboratory studies on swimming speeds have reported values in the same range. However, measured swimming speeds for smaller fish were unrealistically high (2-32 BL s-1) Advantages of the split-beam method are the ability of measuring swimming speed independently of visibility, with minimal disturbance and at large distances. Disadvantages are the inability to distinguish species observed and some variance in target location, which results in calculated average swimming speeds of 2.6 cm s-1 even for a stationary target.n N c       U e u         xqFeb 2000 Issn 0165-7836 English Journal Article ASFA 1: Biological Sciences & Living Resources; Oceanic AbstractsArseneault, M. 19940)Salmon saga: Murphy's law as a fish story Ceres.

Freshwater Q1 01421 Migrations and rhythms; Q1 01341 GeneralaWe monitored habitat use and movement of 27 adult shovelnose sturgeon in Pool 13 of the Upper Mississippi river, Iowa-Illinois, by radio-telemetry in April through August 1988. Our objective was to determine the response of this species to unusually low water conditions in the Upper Mississippi River in 1988. Most (94%) telemetry contacts were made in 3 habitat types: main channel (50%), main channel border where wing dams were present (29%), and tailwaters of Lock and Dam 12 (15%). Habitat use in spring was affected by the extreme low flows. We often found tagged shovelnose sturgeon in the main channel and tailwaters during the spring period (11 March-20 May) where water velocities were highest. This was in contrast to other sites where shovelnose sturgeon did not occupy those areas during years with normal spring flows. Shovelnose sturgeon were typically found in areas with a sand bottom, mean water depth of 5.8 m, and mean bottom current velocity of 0.23 m sec-1. They occupied areas of swifter current but were not always found in the fastest portion o f the pool, and we observed no emigration from the study pool. Linear total range of movement from the tagging site ranged from 1.9 to 54.5 km during the study period.    `Z1997 Issn 0378-1909 English Journal Article ASFA 1: Biological Sciences & Living Resources0)Dahlberg, M.L.

At levels above 6 mg per liter, the final swimming speed was virtually independent of the oxygen concentration. The performance of bass that had been acclimated overnight to elevated carbon dioxide levels was not materially affected by the highest tested concentrations of free current dioxide, averaging 48 mg per liter, at any tested level of dissolved oxygen. For juvenile, coho salmon, Onchorynchus kisutch, at temperatures near 20 oC and carbon dioxide concentrations near 2 mg per liter, any considerable reduction of the oxygen concentration from about 9 mg per liter, the air-saturation level, resulted in some reduction of the final swimming speed. The performance of the salmon was impaired much more markedly than was that of the bass by the same reduction of the oxygen concentration. At oxygen concentrations near and above the air-saturation level, high concentrations of free carbon dioxide, averaging 15 and 61 mg per liter, had a depressing effect on the final swimming speed of coho salmon, even after overnight acclimation. However, this effect decreased at reduced oxygen and concentrations. No measurement effect of free carbon dioxide concentrations near 61 mg per liter was evident at 2 mg per liter dissolved oxygen, and concentrations near 18 mg per liter had little or no effect even at moderately reduced dissolved oxygen levels after overnight acclimation of the salmon to these carbon dioxide concentrations.  6 K           Daum, D.

Split-beam techniques allow for three-dimensional tracking of fish targets as they pass through the sonar beam. Elliptical-beam transducers were deployed from opposite river banks to optimize acoustic coverage and were aimed perpendicular to the current. Sonar systems were operated continuously from August 8 through September 22, 1996. Acoustic data on positional information of 204,153 upstream-traveling chum salmon were collected. Diel patterns in hourly passage rates differed between banks. On the left bank, chum salmon passage was highest during nighttime hours. On the right bank, fish did not show any consistent trend in diel passage rates. Chum salmon were generally shore oriented and swam near the river bottom. During daylight hours, fish were further offshore and closer to the bottom than during night. Besides providing accurate counts of fish passage, riverine split-beam hydroacoustics proved a nonintrusive method for studying the migratory behavior of fish.o   Aug 1998 Issn 0275-5947 English Journal Article ASFA 1: Biological Sciences & Living Resources; Oceanic Abstracts; ASFA Marine Biotechnology Abstracts; Ecology Abstracts   Anonymous 1979&Anadromous fisheries management "Boston, Massachusetts (USA) 0*Massachusetts Division of Marine Fisheries22Completion ReporttFreshwater fishery management; anadromous species; Alosa sapidissima; Osmerus mordax; Alosa pseudoharengus; USA, Massachusetts fishways; Clupeidae; Osmeridae; Pisces Q1 08604 Stock assessment and management; Q1 08582 Fish culturerDuring the project period AFCS 14-1 through AFCS 14-5 (1974-1979), eight fish passage facilities were constructed, four fishways were improved and another 217 were adjusted and cleaned.

One hundred PIT-tagged adult steelhead Oncorhynchus mykiss were released in groups of 10 into an enclosed area of the ladder downstream from the detectors. The tagged fish were detected after they volitionally swam through the weir and slid through the detection system at velocities of 0.6 m/s or greater. Overall PIT tag reading efficiency was 98% and no tag-reading errors were recorded. Individual tag code, date, and time of the passage of each tagged fish were automatically recorded into a computer file and simultaneously printed onto a paper copy. These results suggest that PIT tag monitors of this design could be deployed at select adult passage facilities presently operating in the Columbia River Basin to interrogate returning PIT-tagged adult salmonids.6   1994 Issn 0275-5947 English Journal Article ASFA 1: Biological Sciences & Living Resources; Oceanic Abstracts; Ecology Abstractsn2+Bemis, W.

The main goal of the conference was to attract attention to sturgeons and paddlefishes, still the most speciose group of 'living fossil' fishes, but now fast disappearing from our planet (Birstein 1993, Bemis and Findeis 1994, Waldman 1995). Some presentations at the conference described basic aspects of acipenseriform biology, including evolution, genetics, and life cycles. Others focused on the contemporary status of a particular species or a few species inhabiting the same basin or region; most of these contributions also addressed ongoing conservation efforts. Still other speakers examined current controversies at the interface between science and society, bringing information from a variety of sources to enrich our meeting. These three approaches are reflected by the three part organization of this volume: part 1, Diversity and evolution; Part 2, Biology and status reports; and Part 3, Controversies, conservation and summary. We hope that the included papers offer a broad perspective about contemporary work on the phylogeny of Acipenseriformes, as well as a review of the worldwide status of almost all of the species constituting this order.1997 Issn 0378-1909 English Journal Article; Conference ASFA 1: Biological Sciences & Living Resources; ASFA 3: Aquatic Pollution & Environmental Quality; Oceanic Abstracts x Hackney, P.

Although some anadromous (marine) warmwater species (e.g., American shad, blueback herring) are currently passed upstream and downstream through structures deliberately built for that purpose, effectiveness of this technology for passage of adults and young of potential target species (e.g., paddlefish and sauger/walleye) in Cherokee Reservoir is unproven. Downstream passage is by far the larger and more poorly understood subject of fish migration and should be investigated first. Currently, the Electric Power Research Institute (EPRI) is conducting research on downstream fish passage (Project RP 2694).

Upstream and downstream movement of fish was monitored using weirs with traps. Most of the 27 species had a consistent pattern of larger fish moving upstream and smaller fish moving downstream. Diurnal oxygen series were run to measure the metabolism of the aquatic community. Gross photosynthesis ranged from 0.21 to almost 9 g O2 m-2 day-1, and community respiration from 0.4 to 13 g O2 m-2 day-1 (mean of 290 and 479 g O2 m-2 day-1). Both were highest in the spring. Production per volume and respiration per volume were always much larger near the headwaters than farther downstream, apparently due to the dilution effect of the deeper water downstream. Migration may maintain young fish in areas of high productivity. Other effects of migration may include: prey control, recolonization of defaunated regions, genetic exchange, and mineral distribution. An energy diagram was drawn comparing energies of isolation, leaf inputs, currents, total community respiration, fish populations, and migrations. About 1% of the total respiration of the stream was from fish populations, and over 1 year about 0.04% of the total energy used by the ecosystem was used for the process of migration. Each calorie invested by a fish population in migration returns at least 3 calories. Analysis of phosphorus entering and leaving the watershed indicated that flows were small relative to storages and that this generally undisturbed ecosystem is in approximate phosphorus balance. Upstream migrating fish were important in maintaining phosphorus reserves in the headwaters.  @         @         - @. 0  2 6  8 vpEcology, vol 53, no 4, p 585-604, summer 1972. 9 fig, 3 tab, 99 ref. owrr b-007-nc(5).

Records made of the swimming at different speeds of dace, trout, and goldfish measuring up to 30 cm in length are reproduced. Speed at any particular frequency of tail beat is shown to be directly related to the length of the specimen. Above a frequency of 5 tail beats per second, speed is directly dependent upon frequency up to the maximum values recorded. The results for all sizes and species recorded may be adequately expressed by the formula V=1/4{L(3f-4)}, where V = the speed in cm/sec, f = the frequency in beats per second, and L is the body length in cm. The distance travelled per beat (and hence the speed) is directly dependent upon the amplitude of the tailbeat.Baldwin, C. K.

SW 0835 Streamflow and runoff; Q2 02171 Dynamics of lakes and riversRLThe understanding of seasonal variations in streamflow is important for water resource management. The dynamics of streamflow are often dominated by annual and intra-annual variations, and the global warming debate has also generated an interest in potential changes in the seasonal cycle of hydroclimatic variables. Thus there are mechanistic as well as policy motivations for an empirical analysis of the historical seasonal variations in streamflow. The seasonality of the upper Mississippi River streamflow is investigated in this paper using a 123-year record of daily flow. This long streamflow series provides an interesting look at the high- and low-flow seasons within the year, their interannual variation, and within-season attributes. Evidence for changes in the timing and amplitude of these seasons and the annual flow extremes is presented. Connections to similar trends in regional climate variables are noted. The upper Mississippi River streamflow exhibits bimodal probability distributions for monthly averages and for specific seasons. Transitions across the high- and low-flow regimes corresponding to these modes exhibit memory across seasons and over years. Thus an empirical basis for seasonal or longer prediction is provided. Needs for developing a mechanistic explanation of the empirical observations offered are also indicated.Apr 1999 Issn 0043-1397 English Journal Article Water Resources Abstracts; ASFA 2: Ocean Technology Policy & Non-Living Resources0(tZ]N`$;pe@~g$pp @:Benstead, J.

Increasingly, this linkage is being severed by dams and water abstraction. The ecological impacts of these activities are poorly understood and are largely being ignored by dam operators. We investigated the direct effects of a water intake and low-head dam on the migration of amphidromous freshwater shrimps between the headwater streams and estuary of the Rio Espiritu Santo, Puerto Rico, USA. Both downstream migratory drift of larvae and upstream migration of postlarvae had strong diel patterns, with most activity occurring at night. Unlike large dams on the island, this low-head dam did not act as a complete barrier to the upstream migration of metamorphosed postlarvae. However, the dam did cause large numbers of postlarval shrimps to accumulate directly downstream of the structure. Mortality of drifting first-stage larvae by entrainment into the water intake during downstream migration averaged 42% during the 69-d study period. During low discharges, 100% of the drifting larvae were entrained by the intake. The rate of nocturnal entrainmentinduced mortality averaged 233 larvae/s and peaked at 1167 larvae/s. We used our field data and a 30-yr discharge record to model the long-term impacts of different intake management strategies on the entrainment mortality at this dam. The simulation model estimated long-term mean daily entrainment mortality at 34-62%, depending on the amount of water extracted from the river. Monthly differences in mean daily entrainment mortality (27-76% depending on estimates of abstraction) were caused by seasonal variation in discharge. Modeling of mitigation options suggested that daily entrainment mortality of larvae could be reduced to 11-20% if water abstraction was halted for 5 h during evening periods of peak drift. Impacts of the dam and operations can be significantly ameliorated by 3-5 h stoppages in water abstraction during peak nocturnal larval drift, upkeep of a functional fish ladder, and maintenance of minimum flow over the dam. Since the impacts of dams depend on the hydrology and design of specific water intake systems, mitigation strategies must be tailored to individual dams and intakes. However, our approach and results are likely to apply to low-head dams throughout the range of amphidromous species.b\May 1999 Issn 1051-0761 English Journal Article Ecology Abstracts; Water Resources Abstracts2 F?Casselman, J.

Fishways and fish ladders are uniquely applicable for sampling migrating fish in rivers, especially those with large control dams or high flows. Remote sensing by stationary hydroacoustics has been used where spawning migrations are assessed. Trawling may be used where the current is relatively slow. There are no standardized sampling techniques for large rivers because environmental conditions are often extremely variable. Usually attempts are made to sample selectively only those parts of the river that have low flow and are amenable to bottom-set stationary gear such as gill nets, trap nets, and other fixed gear. Sampling riverine fishes at the community level is much more difficult and requires combining the results of several types of sampling gear (e.g., quantitative sampling using electrofishing or explosives, in combination with large lift nets or block off nets). Portable fish diversion systems exist that could make fish sampling in large rivers much more efficient. Some of these systems, such as portable marine fences, weak electric fields, bubble currents, and hydrosonic pulsers could be used to direct and concentrate fish to improve the actual sampling procedure. Because environmental conditions are more variable in rivers than in lakes, it is essential that if sampling efficiencies are to be compared, environmental conditions must be the same. Sampling of fish populations in rivers where discharge is variable should be conducted in relation to velocity, rather than at fixed stations. ~xPolskie Archiwum Hydrobiologii PAHYA2, Vol. 37, No. 4, p 521-551 , 1990. 6 fig, 6 tab, 92 ref.

Objectives were to document fish movements in response to lockages, to develop recommendations for modified lock operations, and to evaluate hydroacoustic techniques for monitoring fish passage. At the lower gates, estimates of fish passage into the lock increased with duration of opening. At the upper gates, a pulse of fish was generally observed to move out of the lock immediately after the gates opened, and duration of opening did not appear to influence rate of fish passage from the lock into the canal. Fish were observed to move downstream, away from the lock gates, to avoid turbulence created by water dumping during the initial stages of drawdown. Q a Conference 1. Int.

Increasing human population and growth of technology require human society to devote more and more attention to protection of adequate supplies of water. Although perception of biological degradation stimulated current state and federal legislation on the quality of water resources, that biological focus was lost in the search for easily measured physical and chemical surrogates. The "fishable and swimmable" goal of the Water Pollution Control Act of 1972 (PL 92-500) and its charge to "restore and maintain" biotic integrity illustrate that law's biological underpinning. Further, the need for operational definitions of terms like "biological integrity" and "unreasonable degradation" and for ecologically sound tools to measure divergence from societal goals have increased interest in biological monitoring.N1991 Issn 1051-0761 English Journal Article Ecology Abstracts; ASFA 3: Aquatic Pollution & Environmental Quality; Pollution Abstracts; Health & Safety Science Abstracts Karr, J.

Yet over the past century, humans have changed rivers dramatically, threatening river health. As a result, societal well-being is also threatened because goods and services critical to human society are being depleted. 'Health' - shorthand for good condition (eg healthy economy) - is grounded in science yet speaks to citizens. Applying the concept of health to rivers is a logical outgrowth of scientific principles, legal mandates, and changing societal values. Success in protecting the condition, or health, of rivers depends on realistic models of the interactions of landscapes, rivers, and human actions. Biological monitoring and biological endpoints provide the most integrative view of river condition, or river health. Multimetric biological indices are an important and relatively new approach to measuring river condition. Effective multimetric indices depend on an appropriate classification system, the selection of metrics that give reliable signals of river condition, systematic sampling protocols that measure those biological signals, and analytical procedures that extract relevant biological patterns. Communicating results of biological monitoring to citizens and political leaders is critical if biological monitoring is to influence environmental policies.0z1999 Issn 0046-5070 Special issue: River health.

Many such crossings are impassable to migrating fish because of the culvert length and the high water velocities in them. A hydraulic model study tested and developed devices to aid fish passage through culverts. Based on the model study recommendations, Offset baffles and Spoiler baffles were designed and installed at the MacKenzie Highway crossing of the Redknife River. Field testing showed good agreement, between model and prototype results. The effectiveness of both baffle types is inversely proportional to culvert slope. Maximum recommended slope is 5%. A method of judging baffle adequacy is provided. The Offset and Spoiler baffles are recommended, primarily for correcting existing culvert installations and for proposed stream crossings where alternative designs are neither practical nor economical. Minor problems were presented by ice, debris and sediment. Unsuccessful attempts by Arctic grayling and longnose sucker, to enter the Redknife River culverts, were observed; their failures were attributed to overwhelming water velocities associated with elevated culvert outlets.v&Stuart, I.

This study assessed the effectiveness of modifying a salmonid-type pool-and-weir fishway into a vertical-slot design on a tidal barrage on the subtropical Fitzroy River, in Queensland, north-eastern Australia. In 38 paired samples of the top and bottom of the fishway, over 16 months, 29 fish species and over 23 000 fish were collected at a maximum rate of 3400 per day. This study shows much greater potential for success with a vertical-slot fishway as relatively few fish negotiated the original pool-and-weir design. Common species using the vertical-slot fishway included blue-catfish (Arius graeffei [Ariidae]), bony herring (Nematalosa erebi [Clupeidae]), striped mullet (Mugil cephalus [Mugilidae]), barramundi (Lates calcarifer [Centropomidae]), and long-finned eels (Anguilla reinhardtii [Anguillidae]). Freshwater shrimp (Macrobrachium australiense [Palaemonidae]), juvenile crabs (Varuna litterata [Grapsidae]) and long-finned elvers did not ascend the full length of the fishway and specific fishways for these species are recommended. Fish between 25 and 640 mm in length ascended the fishway, although the passage of smaller size classes of immature fish was restricted and this may be important for the sustainability of these migratory populations. The barramundi (200-640 mm) which ascended the fishway were all immature fish. However, during a period of low river flows enlarging the width of the vertical-slot from 0.15 to 0.45 m only encouraged a small number of larger fish (890 mm maximum length) to enter. The strong diel movement patterns of many species will need to be considered in future fishway design. Blue-catfish could ascend the fishway in 2 h, but many fish remained in the fishway and this behaviour may cause crowding and a reduction in fishway capacity. Further work is needed to assess the proportion of fish finding the fishway entrance. However, the findings suggest that vertical-slot fishways with lower water velocities and turbulence than salmonid fishways have great potential to pass the diverse migratory fish fauna of subtropical and tropical rivers.   , < [ i       1 A Dec 1999 Issn 0886-9375 English Journal Article Ecology Abstracts; Water Resources Abstracts; ASFA 3: Aquatic Pollution & Environmental Quality; ASFA 1: Biological Sciences & Living Resources(!Sylvester, J.

However, many of the endemic taxa are threatened with extirpation. To successfully conserve variation within taxa, management agencies must understand the genetic structure of populations. We used allozyme electrophoresis to characterize partitioning of genetic variation within-populations (w-p) and among populations (a-p) of unionids in the Ohio River system and within the Big Darby Creek system of central Ohio. Quadrula quadrula typically occupies large rivers, while Elliptio dilatata is a common resident of small streams such as Big Darby Creek. On average, populations of Q. quadrula contained greater w-p variation (2.1 alleles/locus, 61% polymorphic loci, 24% heterozygosity) than populations of E. dilatata (1.6, 32%, 10%, respectively). Patterns of a-p variation differed between species. Allele frequencies of Q. quadrula were not different among populations >1000 km apart. Populations of E. dilatata showed differences in allele frequencies between populations <100 km apart. Unionid species illustrate at least 2 models of the partitioning of genetic variation. Model I species such as Q. quadrula have a high gene flow among populations; each population contains much of the total variation present within a large geographic region. Model II species such as E. dilatata have restricted gene flow and large amounts of a-p variation; individual populations exhibit unique arrays of alleles. Large river habitats are more stable, capable of supporting larger populations of mussels, and may contain fishes with greater dispersal capability than small streams. The result of this combination is a single large metapopulation in big rivers. Preservation of several populations in big rivers will conserve most of a taxon's genetic diversity. Conservation of similar amounts of genetic diversity in small streams will require protection of a large number of populations within any geographic region. Such differences require that management agencies consider the genetic structure of mussel taxa when developing conservation plans.    -     {      ? J Conference 89.

Effective management of threatened and endangered species requires knowledge not only of abundances of these species but also the degree of variation within species and the geographic distribution of this intraspecific variation. We used allozyme electrophoresis to examine the genetic structure of seven Quadrula quadrula populations from the Ohio, Tennessee, and Tensas Rivers. We then considered the implications of our results for the development of effective bivalve conservation strategies. Descriptive measures of genetic variation within populations are quite high (2.1 plus or minus 0.1(se) alleles per locus; 61.4 plus or minus 2.6% polymorphic loci; 0.24 plus or minus 0.01 heterozygosity) relative to other unionids. Genotype frequencies met Hardy-Weinberg expectations at all polymorphic loci. Among-population variation was low and mostly confined to differences between the Tensas River population (lower Mississippi River basin) and the Ohio River basin populations. Significant differences in allele frequencies among populations were only detected at 3 of 10 loci; no differences in allele frequencies were found among Ohio River basin populations. Genetic distances, though all small, were significantly correlated with geographic distance. Estimated gene flow was high among populations, but variation among populations did tend to follow the predictions of an isolation-by-distance model of dispersal. The low levels of among-population genetic variation are remarkable given that these populations are separated by distances as great as 2,500+ river kilometers. High levels of gene flow may ensure that within-population variation remains high and that populations do not become differentiated due to genetic drift. An optimum conservation strategy for this species in the mainstem of the Ohio River would center on the protection of a number of large populations and maintenance of corridors for dispersal of host fishes. Successful protection of threatened and endangered species requires conservation of both abundance and genetic diversity of unionids. Further work is needed to characterize general patterns of genetic structure within freshwater bivalve species.v   NHConference Symp. on Gene Conservation: Management and Evolutionary Units in Freshwater Bivalve Management, Fort Walton Beach, FL (USA), 19-20 Apr 1997 Dec 1998 Issn 0730-8000 English Journal Article; Conference Genetics Abstracts; ASFA 1: Biological Sciences & Living Resources; ASFA 3: Aquatic Pollution & Environmental Quality=*"Blaxter, J.H.S.

Worldwide rate of extinction of freshwater bivalves is poorly understood at this time. The North American freshwater fauna north of Mexico is represented by 297 taxa in two families. There are 19 taxa presumed extinct, 44 species listed or proposed as federally endangered, and there are another 69 species that may be endangered. A number of these endangered species are functionally extinct (individuals of a species surviving but not reproducing). Extinction of North American unionoid bivalves can be traced to impoundment and inundation of riffle habitat in major rivers such as the Ohio, Tennessee and Cumberland and Mobile Bay Basin. Damming resulted in the local loss of the bivalves' host fish. This loss of the obligate host fish, coupled with increased siltation, and various types of industrial and domestic pollution have resulted in the rapid decline in the unionoid bivalve fauna in North America. Freshwater communities in Europe have experienced numerous problems, some local unionoid populations have been extirpated, but no unionoid species are extinct. Three taxa from Israel are now reported as extinct. Other nations such as China that have problems with soil erosion and industrial pollution or have numerous dams on some of the rivers (e.g., South America: Rio Parana) are probably experiencing problems of local extirpation if not the extinction of their endemic freshwater bivalve fauna..(Conference Annual Meeting of the American Society of Zoologists and the Canadian Society of Zoologists, Vancouver, BC (Canada), 27-30 Dec 1992 1993 Issn 0003-1569 English Journal Article; Conference ASFA 1: Biological Sciences & Living Resources; ASFA 3: Aquatic Pollution & Environmental QualityM^.(Durbin, A.

The total nutrient input to Pausacaco Pond, Rhode Island, USA, from alewives is estimated to amount to 0.43 g P, 2.7 g N, and 16.8 g C/m2 over a 2-month period. This is largely through mortality of the spawning fish, and to a lesser extent through excretion. These inputs were much greater than the eventual nutrient loss to the system through emigration of juvenile fish. In tank experiments using pond microcosms, the initial response to the addition of the fish was a large phytoplankton bloom and an increase in litter respiration. The phytoplankton bloom was shortlived, and the most lasting effect was an increase in production and respiration in the leaf litter. This increased production in the litter community would support a long lasting supply of insect and benthic invertebrate food for young fish. The respiration rate of autumn leaves incubated in alewife streams during the migration was significantly higher than that of leaves incubated simultaneously in a stream which had no alewife run. Respiration rates of leaves incubated in the same streams before the arrival of alewives did not differ significantly. The increase in litter respiration, an indication of microbial and invertebrate activity on the leaf surface, was attributed to the additional nutrients supplied by the fish.  0 9  : haUsing Smart Source Parsing English Journal Article ASFA 1: Biological Sciences & Living ResourcesDynesius, M.

Spawning occurs in spring at temperatures between 17 and 21 oC over rock or gravel substrate downstream from dams, near rock structures, or in tributaries, most males reach sexual maturity at 5 years, most females at 7 years. Adults do not spawn every year. Shovelnose sturgeon are found in large, turbid rivers and frequently concentrate in areas downstream from dams or at the mouths of tributaries. Population densities range up to 2500 fish per km. They are commonly found in areas of current over sandy bottoms or near rocky points or bars, where they feed primarily on aquatic invertebrates. The shovelnose sturgeon is classified as a sport species in 12 of 24 states where it occurs. Commercial harvest is allowed in seven states, where fresh shovelnose sturgeon sell for 55 to 88 cents per kg, smoked shovelnose for about $5.75 per kg, and roe from 33 to 110 dollars per kg. About 25 tons of shovelnose sturgeon are harvested commercially each year. Shovelnose sturgeon are considered extirpated in three states, fully protected in four states, and rare, threatened, or of special concern in eight states. Populations are considered stable throughout most of the upper Mississippi, lower Missouri, Red, and Atchafalaya rivers. Three states, Wyoming, West Virginia, and New Mexico, have developed plans to reintroduce the species into rivers where it has been extirpated.  4    lf1997 Issn 0378-1909 English Journal Article; Conference ASFA 1: Biological Sciences & Living ResourcesH> > Conley, S. 1990Upstream downstreamdAtlantic Salmon Journal393 30-31Salmo salar; anadromous migrations; hydraulic structures; dams; resource conservation; USA, Connecticut R. fishways Freshwater Q5 01522 Protective measures and controlan*The author describes the efforts of one man to manage anadromous fish, particularly with respect to Connecticut River Atlantic salmon Salmo salar and the complicated problem of fish passage -- how to get fish around the many formidable barriers blocking their annual migrations to and from the sea.   d]1990 Issn 0044-992x English Journal Article ASFA 3: Aquatic Pollution & Environmental Qualityr  Conover, G.A.

In 3 different flood plains of the Upper Rhone River, 1015 point samples yielding 4573 juveniles (0+) from 21 species were collected from 48 ecosystems of various geomorphological origin. The results demonstrate the lotic-to-lentic succession of floodplain ecosystems to be a series of non-sequential reproductive zones, with spawning conditions being reflected by the specific composition and guild structure of the YOY fish assemblages. The habitat diversity and the fish reproductive potential of floodplain ecosystems are strongly influenced by geomorphological origin and by past and present hydrological conditions.Q`Z1989 Issn 0378-1909 English Journal Article ASFA 1: Biological Sciences & Living ResourcesJ D Cowx, I.

However, the mechanisms by which it has been achieved have varied greatly as has the degree of success in maintaining migratory pathways. Most attention has focused on upstream migration of salmonids past medium and large impoundments (weirs and reservoir dams). More recently, attention has focused on using alternative channels, such as canoe slaloms, to bypass weirs and barrages, and improving access to natural spawning beds past small man-made obstructions such as road culverts and badly designed or located low weirs which impede upstream movement. In recent years, in the face of declining European eel Anguilla anguilla stocks and emphasis on improving fishing for other non-salmonid fishes, provision has been made for improving upstream migration of elvers and non-salmonids over difficult and insurmountable man-made obstructions. Legislation and provision for the design of fish passage facilities for migratory salmonids are under the direct control of the Environment Agency. They impose strict guidelines for designing passes and require that facilities at new barrages, particularly in estuaries, are adequately tested before they are given approval. With increasing pressure on improving river fisheries and the environment, there are many rivers now being considered for rehabilitation. This includes providing fish passage facilities at the many weirs built on rivers in the industrial past to providing renewed access to the headwater spawning and nursery areas. To date, little attention has been paid to the economics of such activities but this situation is changing rapidly and demands for cost benefit analysis are being imposed. An example is described where the decision to build fish passes on the many weirs impeding upstream migration was deferred on economic grounds. Finally, there are some controversial situations, where passage past natural barriers to previously inaccessible spawning and nursery grounds are discussed.Conference Fish Migration and Fish Bypass Channels Symp., Vienna (Austria), 24-27 Sep 1996 Fish Migration and Fish Bypasses, Fishing News Books, 1998, pp. 220-235 Price: pound sterling 65.

Using analytical considerations and experimental observations, a flow equation has been developed between the discharge, diameter, depth, and slope for a culvert fishway with the standard offset baffle system. The velocity field at the slot has also been evaluated. Some further experiments were performed to assess the effect of baffle spacing and height on the hydraulics of the culvert fishway. Based on preliminary experimental observations and theoretical considerations, a functional relation has been developed between the dimensionless discharge (Q) and the relative depth (yo/D) for culvert fishways with the offset baffle system. This relation has been evaluated using experimental results on two smooth pipes and one rough pipe. These relations are of the form (Q = C(yo/D) to the n power), where the average dimensionless coefficient (C) and the exponent (n) have been experimentally found to be equal to 12.0 and 2.6, respectively. The velocity profiles at the slot offset system are similar and follow a power law with U and the height of the baffles as the scales. The velocity scale (U) in terms of the square root of (gDSo) has been found to be equal to 12.8(yo/D). The effect of doubling the height and keeping the same spacing of the baffles increases the flow resistance appreciably. Keeping the standard height but reducing the spacing to one-half of the standard spacing also improves upon the performance of the standard baffle system.Canadian Journal of Civil Engineering CJCEB8 Vol. 15, No. 6, p 1043-1051, December 1988. 8 fig, 14 ref.

It is known that the flow over the weirs can be either in the plunging or streaming mode. When the flow is in the plunging mode, the water level in the pool immediately below the weir is generally below the crest of the weir. In the streaming flow mode, a surface stream appears to flow over the crest of the weirs, skimming over the water surface in the pools in between. For pool-weir fishways in the plunging flow regime, a simple weir analysis has been found to be adequate with the dimensionless discharge Q sub + = 0.61. For the surface streaming state, the dimensionless discharge Q sub was found to be equal to 1.5 x the square root of (L/d), where L is the length of the pool and d is the depth of the surface stream. A criterion has been established to predict the transition from plunging to surface streaming state.Journal of Hydraulic Engineering (ASCE) JHEND8 Vol. 114, No. 8, p 939-944, August 1988. 1 fig, 4 ref.

Hosts were determined as those that produced juvenile mussels from glochidial infestations in the laboratory. The following mussel-fish-host relationships were established: Strophitus subvexus with 10 species including Cyprinidae, Catostomidae, Fundulidae, Centrarchidae, and Percidae; Pleurobema furvum with Campostoma oligolepis, Cyprinella callistia, C. venusta, Semotilus atromaculatus, and Fundulus olivaceus; Ptychobranchus greeni with Etheostoma bellator, E. douglasi, Percina nigrofasciata, and Percina sp. cf. caprodes; Lampsilis perovalis with Micropterus coosae, M. punctulatus, and M. salmoides; Medionidus acutissimus with Fundulus olivaceus, Etheostoma douglasi, E. whipplei, Percina nigrofaciata, and Percina sp. cf. caprodes; and Villosa nebulosa with Lepomis megalotis, Micropterus coosae, M. punctulatus, and M. salmoides. Fundulus olivaceus served as hosts for 3 species and carried glochidia for long periods for 2 other species, suggesting that topminnows may serve as host for a wide variety of otherwise host-specialist mussel species. Host relationships for the species tested are similar to congeners. Methods of glochidial release, putative methods of host-fish attraction, and gravid periods are described for the 6 species.E               & 7 = R T h j t u               , 2 E F T Z f h ~                - / = C O Q c Sep 1997 Issn 0887-3593 English Journal Article ASFA 1: Biological Sciences & Living Resources; ASFA 3: Aquatic Pollution & Environmental Quality; Ecology Abstractsn` F] Gebler, R.

Using the annual proportional flow deviation as a measure of river regulation, the Paroo River catchment was assessed as unregulated, the Darling River catchment as mildly regulated and the Murrumbidgee River and River Murray catchments as highly regulated. A total of 11 010 fish, representing nine native and three alien species, was caught during high and low flow seasons in the four catchments. Native species, such as golden perch Macquaria ambigua (Percichthyidae), bony herring Nematalosa erebi (Clupeidae) and spangled perch Leiopotherapon unicolor (Terponidae), dominated fish communities in the Paroo and Darling catchments, but alien species, mostly carp, Cyprinus carpio (Cyprinidae), were also abundant. Both native and alien species were more abundant in these catchments after flooding, but there was little change in species composition between high and low flow seasons at the catchment level. Carp dominated communities in the Murray and Murrumbidgee catchments. There was a significant trend for reduced species diversity in increasingly regulated catchments. River regulation may alter the relative abundance of native and alien fish by desynchronizing environmental cycles and the reproductive cycles of native species. Ordination of species abundances showed discrete fish communities that reflect the geographical separation between catchments. Differences between communities are related to opportunities for dispersal, the environmental tolerances of dominant species and the modifying effects of river regulation. Fish communities in lakes exhibited less seasonal variation than riverine communities within the same catchment, indicating the greater seasonal stability of lakes compared with regulated and unregulated river reaches. Management of fish resources needs to include catchment-specific strategies within current State and basin-wide management programmes.

Most of these technologies are highly engineered and follow design criteria that have been developed with the aid of both hydraulic modelling and empirical data. Concurrent with these developments is an increasing interest in more nature-like bypass designs, especially at small-scale or low-head river barriers. This interest is not accompanied by specific or even general design criteria, and thus there may be some hesitance to apply such designs more broadly. This chapter presents conceptual guidelines for both defining and planning nature-like bypass channels, primarily based on experiences gained in Austria but also considering their potential application elsewhere. A basic planning strategy is presented based on river size and general channel morphology in consideration of the fish assemblage present, the goal being to mimic natural systems in which the species of interest are found, rather than engineering channels that accommodate set hydraulic criteria. Emphasis is placed on the site-specific nature of such constructions, their inherent heterogeneity, and necessity for post-construction monitoring and adaptation. The role that nature-like bypasses can play in providing critically needed flowing water habitat in heavily engineered rivers is also articulated.Conference Fish Migration and Fish Bypass Channels Symp., Vienna (Austria), 24-27 Sep 1996 Fish Migration and Fish Bypasses, Fishing News Books, 1998, pp. 348-362 Price: pound sterling 65.

GREAT predicted that backwater habitat would be lost and the fishery would decline riverwide over a 50-year period unless management changed. Twenty years into that 50-year period, long term data from fisheries monitoring along 581 miles of the river bordering Illinois has been gathered. From 1976-95, 483 electrofishing collections totaling 125,503 fish of 98 species were made at 33 locations. Species richness and catch per unit of effort analyses indicate that certain backwater fish species have declined, while river channel species have increased in number and frequency of occurrence.ab\Dec 1997 Issn 0270-5060 English Journal Article Water Resources Abstracts; Ecology Abstracts Beumer, J.

The River is a 60 km long tributary forming part of the Werribee River coastal drainage. The Merrimu Reservoir Project providing a domestic water supply for Melton and Bacchus Marsh involved construction of diversion weirs on Goodman Creek and the Lerderderg River. The ladder incorporates 42 steps with a trap bay at step 36. It has a slope of 1:10. A Nylex plastic screen covering the ladder prevents fish escaping and reduces the amount of leaf-litter and other debris falling into the ladder. A two way trap covered by a fine mesh was installed in the trap bay to monitor fish usage of the ladder. Monitoring of the trap and electrofishing were carried out on a weekly basis for 21 weeks. A total of 69 specimens were taken in the trap during the monitoring period, about half in each trap section. While the fish ladder design was suitable for the larger river blackfish and larger brown trout, few smaller specimens of these two species were caught in the trap. The other three species, short-finned eel, roach and Australian smelt, were poorly represented in trap catches suggesting that they could not cope with the fish-ladder in its then existing design.

Within the first 30 min after release, significantly more smolts passed the modified weir than the standard weir, but no differences in passage rate between weir types were noted for juvenile American shad. More Atlantic salmon smolts and juvenile American shad were passed by the modified weir in groups of two or more than were passed by the standard weir. Mean lengths of passed and nonpassed smolts were not significantly different between weir types, but American shad passed by the sharp-crested weir were significantly smaller than nonpassed fish. Most individuals of both species that passed the modified weir maintained positive rheotaxis and strong swimming throughout the length of the weir. In addition to acceleration, visual cues may be an important factor in avoidance behaviors near bypass entrances. The observed reduction of delay time before passage and maintenance of school integrity may facilitate appropriate timing of emigration and enhance passage survival.  7 B ^ o       Jan 1998 Issn 0002-8487 English Journal Article ASFA 1: Biological Sciences & Living Resources; Ecology Abstracts; Animal Behavior Abstracts; Water Resources Abstracts z*$Harris, J.

Many fish in coastal drainages are catadromous, while inland-drainage species are commonly potamodromous. Declining populations have been linked with fish-passage obstruction through water-supply development, with thousands of instream barriers. Attempts to restore fish passage are inhibited by the large numbers of barriers, and by the high cost of established technical fishways. The need for low-cost fishways has led to a test of rock-ramps, which use large rocks in transverse ridges, creating pools and small falls, to mimic stream riffles. Twelve rockramps have been built, generally sloping at 1:20. Some occupy only part of the width of the stream channel, but most are built full-width. Problems encountered included structural movement in unsupported ramps, excessive head losses, and fish missing the entrance of partial-width ramps. To assess the effectiveness of four rock-ramps of up to 1.5 m head loss, we compared species representation and length frequencies among fish arriving at the base of the ramps with those caught at the upstream exit. Preliminary results show rockramp fishways can be cheaper than technical fishways, and can provide passage for the species and sizes of native fish examined.tConference Fish Migration and Fish Bypass Channels Symp., Vienna (Austria), 24-27 Sep 1996 Fish Migration and Fish Bypasses, Fishing News Books, 1998, pp. 331-347 Price: pound sterling 65.

Freshwater Q1 01604 Stock assessment and managementZSaugers Stizostedion canadense were once common representatives of the Missouri River fish assemblage. Prior to channelization and impoundment, they comprised from 10 to 65% of the main channel big-river fish group. They utilized the slower side channels and backwaters seasonally for feeding, resting, and maturing, but the main channel was important for breeding habitat. Since the onset of channelization and impoundment, saugers have been reduced by as much as 98% in some areas, and the trend toward extirpation continues unabated today. Recovery of native sauger stocks will require a complete cessation of harvest, recovery of the natural hydrograph, recovery of sediment transport, recovery of snags and organic matter dynamics, and re-connection of cut-off side channel morphology.   `Z1994 Issn 0077-6351 English Journal Article ASFA 1: Biological Sciences & Living Resources Hesse, L.

Freshwater Q1 01604 Stock assessment and management; Q3 01582 Fish cultureFlathead Pylodictis olivaris and blue Ictalurus furcatus catfish in the Missouri River have been over-exploited. Commercial harvest of both species ended in 1992, but commercial fishing was only part of the problem. The percentage of flathead catfish longer than 407 mm total length is very low. The density of flathead catfish in the upper unchannelized Missouri River is 6 to 10% of the density in the lower unchannelized reach, and channelized section density is six times greater than unchannelized density. Tagging studies have revealed that the population of flathead catfish in the upper unchannelized reach consists of less than 1,000 individuals. Blue catfish have been nearly extirpated and should be listed as endangered in Nebraska's portion of the Missouri River. Overharvest, reduced turbidity, and the removal of large woody debris has caused the reduced population density. Management must include restricted harvest, closed areas, protected size classes, increased turbidity, and restoration of a floodplain with seasonal flooding. In the near term, large trees from the river bottom or from communities near the river should be placed in the channel to enhance in-stream cover.     & 8 |v1994 Issn 0077-6351 English Journal Article ASFA 1: Biological Sciences & Living Resources; ASFA Aquaculture Abstracts Hesse, L.

Freshwater Q1 01604 Stock assessment and management; Q3 01582 Fish cultureoThe average size of Missouri River channel catfish Ictalurus punctatus has declined. The percentage 10 years old or older is 4.8% compared with an unexploited population in which 32% are 10 years and older. From 1944 through 1988 commercial harvest declined as much as 64%. Total mortality was 37% at age 4 and 79% at age 5. The increased mortality occurred as they reached 13 inches and became fully recruited to the commercial fishery. Harvest statistics are not wholly reliable because reports are not verifiable and commercial fishers do not return fish tags. Harvest exceeded a reasonable limit for maximum sustained yield. Commercial minimum-size limits have been ineffective due to their design and because they are not easily enforced. Commercial catfishing was closed in action taken by the Nebraska Game and Parks Commission in November 1990 to take effect 1 January 1992. Since then the mean size has increased from 286 mm total length (TL) to 324 mm TL in 25.4-mm mesh net samples from the channelized section of the Missouri River, and the percentage of fish longer than 330 mm TL increased from 8% in 1987 to 44% in 1993.i 3 F |v1994 Issn 0077-6351 English Journal Article ASFA 1: Biological Sciences & Living Resources; ASFA Aquaculture AbstractsX$Simonson, T.

Young that had recently risen from the nest gravel (7-9 mm standard length, SL) were displaced from field nest sites and from laboratory flumes at low velocities (8 mm/s). Nests in areas of higher velocities (15 mm/s) failed to produce young. Comparison of respiration and foraging rates of young fish (16-71 mm SL) in laboratory flumes suggested that the ratio of feeding reward to energy expenditure reached a maximum at current velocities between 80 and 130 mm/s. This velocity range produced maximum growth in the flumes and was also the range most frequented by young (43-116 mm SL) in the Mississippi River. e z 1990 Issn 0002-8487 English Journal Article ASFA 1: Biological Sciences & Living Resources; Ecology Abstracts; Animal Behavior Abstracts; Health & Safety Science Abstracts,<6Skalski, J.

Four alternative approaches are compared among themselves and with stratified random sampling (STRS). Stratifying systematic sampling (STSYS) on a daily basis is found to reduce sampling error in multiday monitoring studies. Although sampling precision was predictable with varying levels of effort in STRS, neither magnitude nor direction of change in precision was predictable when effort was varied in systematic sampling (SYS). Modifying systematic sampling to include replicated (e.g., nested) sampling (RSYS) is shown to provide unbiased point and variance estimates as does STRS. Numerous short sampling intervals (e.g., 12 samples of 1-min duration per hour) must be monitored hourly using RSYS to provide efficient, unbiased point and interval estimates. For equal levels of effort, STRS outperformed all variations of SYS examined.tm1993 Issn 0706-652x English Journal Article ASFA 1: Biological Sciences & Living Resources; Oceanic AbstractsRx.

Daily and hourly passage of smolts was accessed by video recording. Migratory activity was mainly nocturnal, diurnal movements increasing at the end of emigration period. Analysis of results showed that the lights significantly increased the rate of passage. Visual observation showed that illumination duration, light location and intensity may be important parameters in effective application of mercury lights for attraction. Three to eight times as many fish were bypassed with the lights on than with the lights off.

The equipment can be easily deployed by one person and is designed to withstand the forces created by strong current flow. This equipment is essential to the operation of the hydroacoustic system to maintain accurate and defensible enumeration of migrating salmon. Fish migrating in rivers with higher current flow tend to be shore and bottom oriented and require a shore based system aimed close to the river bottom and perpendicular to the flow. Specialised equipment must be used to move fish away from the shore so they can be counted. The operator must be able to aim the transducer precisely to ensure that the beam is close to the river bottom and covers the volume where fish passage occurs. The beam aim must be repeatable after moving the equiment. Since the detection characteristics vary between transducers, the ability to detect should be determined for each transducer in the environment where it is used.Can. Tech. Rep. Fish. Aquat.

A total of 157 897 individuals of 23 species (bleak Alburnus alburnus not included) were captured in the fish ladder. The dominant species captured, in order of abundance, were bleak (not counted), roach Rutilus rutilus (87.7%), silver bream Abramis bjoerkna (4.3%) and European chub Leuciscus cephalus (2.0%). Non-rheophilic species accounted for around 93.4% of the total. Most seasonal movements of cyprinid fishes are observed in spring and are reproductive migrations. Roach, Eurasian dace Leuciscus leuciscus, silver bream, nase Chondrostoma nasus, and European chub of indeterminate sex begin migrating in mid-March and continue as long as the water temperature is between 10 and 15 degree C. Movements of mature European chub, bream Abramis brama, and barbel Barbus barbus begin in mid-May, when water temperature reaches 13-15 degree C. Salmonids migrate in May-June and autumn. While seasonal periodicity of migration is clearly associated with water temperature, circadian variations are dependent on luminosity.

From 1993 to 1995, nearly 1000 adult salmonids passed through the fishway despite heavy fishing below the dam. Of environmental variables measured, water temperature, headwater level, and discharge through the power plant in relation to season changes explained most of the variation in Baltic salmon, Salmo salar L., numbers.

It is closed from the atmosphere to prevent the addition of nitrogen to the water passing through the conduit. A constant gradient and constant flow facilitate fish passage. Spaced along the conduit are series of flow disrupting projections which cause the water to form areas of eddying water currents providing resting areas for the fish.

Hierarchical classes were geomorphological region (straight river run, run with an island, and river curve), river cross section (channel or shoal), and microhabitat (water depth, bottom current, substrate, and illumination). Coastal wandering juvenile Atlantic sturgeon were summer visitors to the Merrimack River, where they used a narrow range of habitat on all spatial scales, e.g., run-with-island, the channel portion of the cross section, and sand substrate. Shortnose sturgeon, year-round residents in both rivers, showed great individual variation in habitat use, and all ages selected a broad range of habitats on all spatial scales. However, shortnose sturgeon in both rivers preferred curves with sand or cobble substrate and avoided runs regardless of substrate. Individuals used channel or shoal at rates ranging from 0 to 100% on a weekly time scale in an unpredictable manner. Connecticut River shortnose sturgeon increased their use of curves, channels (deep water), and sand substrate in the fall. This strategy may conserve energy because these conditions usually reflect slow water velocity. Winter habitat selection continued the fall pattern, but was less variable because habitat affinity was highest among wintering fish. Documenting individual fish use of large-scale habitat revealed habitat relationships that would not have been discovered if only fish use of microhabitat had been studied.a # 9 P h Mar 2000 Issn 0002-8487 English Journal Article Ecology Abstracts; ASFA 1: Biological Sciences & Living Resources; Oceanic AbstractsJDDesigning hydraulic structures using a 2-dimensional numerical model Laasonen, J. Vesitalous5n 29-31o A numerical model based on the finite-difference integration of non-linear equations for 2-dimensional unsteady flow in a horizontal plane is presented. Nearly horizontal flow and hydrostatic pressure are assumed in the equations. The algorithm used in the model has two parts. The one calculates the linearized terms, including resistance and bed forms, using the scheme of Abbott-Ionescu and the Alternating Direction (ADI) method; the other calculates the convective terms explicitly. An operator accurate to the third order for both space and time is employed. Use of this mathematical model for the lay-out of a hydraulic structure is described. Koivukoski hydro powerplant is on the River Kymijoki in Finland. It was found that fish migration through the fish ladder was better during the flood than at other times. To improve the operation of the fishway it was decided to release auxiliary water through the gates of the regulating dam. The area below the fishway was modelled to find the optimal flow pattern at the entrance of the fishway. 1994numerical analysis; hydraulic structures; finite difference method; unsteady flow; hydroelectric plants; dams; floods; river regulations; engineering; fish passages SW 6090 Fisheries engineering; SW 6010 StructuresOriginal Title Vesirakenteiden suunnittelu 2-dimensionaalista virtausmallia apuna kaeyttaeen 1994 Issn 0505-3838 Finnish Journal Article Water Resources Abstracts \"Harvie, C.

High variability in counts within day and season required more intensive sampling than suggested by previous studies to estimate the population mean to within a given percent relative error. Stratification in some cases doubled or trebled the precision of the estimated mean relative to the mean obtained from simple random sampling, whereas systematic sampling produced no gain in precision. Stratification to reduce the number of sample units required for a given precision may reduce the power of a test to detect differences between annual estimates of population means, depending on their variances. The importance of these interrelated factors should be determined before a particular scheme and level of effort are chosen for sampling.s ! 5 North American Journal of Fisheries Management NAJMDP, Vol. 10, No. 1, p 39-45, Winter 1990. 3 fig, 2 tab, 13 ref.

The system, based on image-processing software and a personal computer, compressed videotapes of the passage of Pacific salmon Oncorhynchus spp. by 75% ( plus or minus 6.8%). The system reduced the length of tape that had to be reviewed without significantly altering fish counts made from the tapes.

The combined location and time data formed a 1,890-d statistical population of fish passage. This sample of source tapes was stratified post hoc into three different categories of fish-passage densities, measured by the number of fish on every 24 h of recorded tape (<100, 100-400, and >400 fish/d). Source tape compression was inversely related to fish passage density. The editing system processed and compressed source videotape recordings representing 24 h of monitoring at a particular site in approximately 2 h. The system was simple to use and did not require operator attention during the automated editing process. The videotape editing system can make it easier, faster, and less expensive to review videotapes of migratory fish passage and is most useful at locations or during times when relatively few fish will be observed per day.

The models were made for a fishway with vertical slots. The Kirakkakongas model was 30 m long with a vertical ascent of 2 m. The Keminmaa model was made on a scale of 1:4. The ascent behavior of fish was studied at discharges of 30-100 L/s. The depth of the basins was 30-60 m. The Keminmaa model allowed evaluation of different experimental designs, measuring equipment, and the methodology of fish behavior experiments. The Kirakkakongas model made it possible to carry out parallel and more detailed experiments. At Karakkakongas most fish swam up to the lower basin from the entrance downstream, in which the flow was strengthened by the flow from the lower channel. The flow velocity was 0.3-1.5 m/s, depending on the magnitude of the discharge used in the mouth of the fishway. In the Kirakkakongas fishway, fish swimming behavior was significantly affected by the temperature of the water and the flows in the basins and openings. At the lowest discharge (33 L/s), most fish swam up and at the highest (100 L/s) only a few swam up. At the lowest discharge it was possible to obtain flow conditions in the model in which whitefish of different sizes were able to swim without difficulty. The suitable flow rate greatly depends on the species for which the fishway has been designed. For trout and salmon the flow can be very strong but whitefish require a calmer flow. In the Keminmaa models the greatest proportion of the fish swam up the fishway when the water temperature was 16-19 oC. The origin of the fish did not affect their rising activity. The best discharge for whitefish in this fishway model was 25-35 L/s. At lower discharges the whitefish also rose well. At discharges over 35 L/s, the swimming was uncontrolled and only a few whitefish were able to swim up. The rising activity of whitefish increased towards autumn, although the water was still warm. Fish swam up most actively in the morning. [  \ b\Aqua Fennica AQFEDI Vol. 18, No. 2, p 171-178, 1988. 8 fig, 9 ref. Water Resources Abstracts+ HABurkhardt, R. W. Stopyro, M. Kramer, E. Bartels, A.

Our biogeographic analysis (based on the most recent phylogenetic analysis including fossil Acipenseriformes) suggests that Acipenseriformes originated in Europe, and that early diversification took place in Asia. Acipenseriformes do not have a common life history; variation within and between species is the rule rather than the exception. The few relatively well-known case studies (e.g. Caspian Sea sturgeons, European Atlantic sturgeons in the Gironde system, and shortnose and North American Atlantic sturgeons in rivers of the east coast of America) greatly influence what we think we know about sturgeon biology. Our present level of phylogenetic understanding does not allow us to determine whether anadromy or potamodromy is the plesiomorphic life history pattern for Acipenseriformes. We propose that rivers in which spawning occurs must be the central unit for biogeographic analysis of living Acipenseriformes. After mapping these rivers, we recognized nine biogeographic provinces for acipenseriforms. Some repeated historical patterns emerge from this analysis, but, again, we are limited by our current understanding of phylogenetic relationships within the genus Acipenser in particular. Distribution and biogeographic data are central to deciding where to make new efforts to update existing status information for acipenseriform species. We single out a widely ranging and highly variable species, Acipenserruthenus, as particularly intriguing, for it spans three of our nine biogeographic provinces, and apparently has different life history patterns in different river systems. Finally, we note new areas in need of basic research, particularly the need for more detailed descriptions and analyses of life histories of different populations of sturgeons.y1997 Issn 0378-1909 English Journal Article; Conference ASFA 1: Biological Sciences & Living Resources; Oceanic Abstracts2,Bender, M.

Fishways contribute to the sustainable development of water resources projects by providing a path that allows fish migrations to be maintained. A prototype expert system (FDES) has been developed to recommend the most suitable fishway type for given design conditions. A recommendation is provided on the basis of fishway hydraulics, fish passage performance, and cost requirements. Fishway design demands expertise in various scientific disciplines such as hydrology, hydraulics, and fish biology. Expert system technology may be used to reduce design time requirements and to serve as a teaching aid to inexperienced engineers by organizing and accessing the cumulative knowledge of the most experienced designers. The rule-based expert system development tool, VP-Expert, supplies the backward chaining control structure for accessing the knowledge within the prototype.Conference Canadian Hydrology Symp., Burlington, ON (Canada), 29-30 May 1990 EXPERT SYSTEMS AND STATISTICAL METHODS IN WATER RESOURCES., 1992, pp. 115-127, Environmental Monitoring and Assessment [ENVIRON.

The flow of the MFK is controlled by several weirs, each circumvented by a fish pass consisting of a sequence of nature-like pools connected by flumes. Physical conditions were measured in the bypasses and at the entrances across varying discharges. Fish passage was recorded using traps during spring and early summer from 1993 to 1995. Electrofishing samples in the pools below the weirs, and in a stretch of the canal below the lowermost weir, were compared with the species composition found in the traps. Flow experiments showed that the most efficient bypass channel discharge is about 0.25 m2u3/s, which provides both large cross-sectional areas with low flow velocities and high water depths within the flumes. There was no significant correlation between attraction flow (412% of the MFK mean flow) and fish passage. From 1993 to 1995 more than 150000 individuals of 40 species passed the bypass channels. Species composition was dominated by so-called 'non-migratory' small-sized species; juvenile fish comprised 14% of the catch. Comparing species composition below the weirs with passage provided a useful tool to assess species-specific efficiency of the bypass. This study proved the effectiveness of two nature-like bypass channels in a lowland river for almost all occurring species and lifehistory stages.

Research related to the development of water level management plans is being conducted under the Long Term Resource Monitoring Program. Research strategies include investigations of cause and effect relationships, spatial and temporal patterns of resource components, and alternative problem solutions. The principal hypothesis being tested states that water level fluctuations resulting from navigation dam operation create less than optimal conditions for the reproduction and growth of target aquatic macrophyte and fish species. Representative navigation pools have been selected to describe hydrologic, engineering, and legal constraints within which fish and wildlife objectives can be established. Spatial analyses are underway to predict the magnitude and location of habitat changes that will result from controlled changes in water elevation.HConference Symp. on Floodplain Rivers, (np), (nd) 1991 Issn 0886-9375 English Journal Article; Conference ASFA 1: Biological Sciences & Living Resources; ASFA 3: Aquatic Pollution & Environmental Quality; Ecology Abstracts; Health & Safety Science Abstractsl B;Lubinski, K.

Some ecologically important characteristics that serve as indices of overall system status include depositional habitats, vegetation, invertebrates, fish biodiversity, and our capability to apply information to achieve ecological goals. The filling of depositional aquatic habitats has been measured sufficiently to identify this as the major long term resource problem in navigation pools. Many depositional habitats currently are at high risk of entering a successional phase that will be characterized by poor water quality and reduced aquatic vegetation. One of the first steps in the strategy will be the establishment of ecological objectives and action levels appropriate for a large flood plain river.Rept.

Freshwater Q5 01523 Conservation, wildlife management and recreation; Q1 01582 Fish culture; Q3 01582 Fish culturejcThe potential for using the navigation locks of the River Murray to enhance the passage of migratory fish was examined. The upstream movement of fish through Lock 15 at Euston Weir was monitored during simulated standard operations of the lock and during modified operations. The latter operation used the gates of the lock partially open with a one metre gap and water flowing through this gap at 0.5 m/s. Fish movement was measured during three replicates of each type of operation. The modified operation of the lock led to a marked increase in fish passage. Thirteen fish moved upstream through the lock during three standard operations, and 601 fish moved through the lock during the three modified operations. Native fish constituted 90% of the catch. Using the navigation locks to pass migratory fish is valuable for enhancing fish passage in the River Murray but not a substitute for new fishways. Because the entrances of the locks are downstream of the face of the weir they can never act as highly efficient fishways. Nevertheless, the simple modifications to standard lock-operating procedures can provide a worthwhile adjunct to fishways in meeting the migration requirements of the River Murray native fish fauna. This study was funded by the Murray-Darling Basin Commission, which has since agreed to modify the operating procedures of the locks under its control.A@9Conference 19. Annu. Conf. and Workshop.

Sites were established 35 km above the weir and less than 1km and 6km below the weir. These sites were sampled monthly with gill-nets and fyke-nets from January 1990 to June 1992. Upstream fish movement was inferred from differences in relative fish density between the three sites. Potentially migrating fish which entered the base of the fishway were also trapped each month, and the numbers and species of fish reaching the top of the fishway were monitored daily at other times. Large accumulations of fish were recorded below the weir, particularly of golden perch and silver perch. In these two species the dominant migrating group was immature sub-adults, which appeared to move upstream in response to a wider range of environmental cues than adults. Over 4500 fish used the new fishway in the first ten weeks of operation and most size-classes and species of fish moving upstream appeared able to ascend the fishway. Reproductively mature silver perch moved upstream during small increases in flow in summer. These flow events are severely affected by river regulation, which may explain the decline in silver perch indicated by commercial catches in the river and also supported by historical data of fish movements through weirs.

The construction of a series of canals and interconnecting waters during the 18th and 19th centuries facilitated the spread of some species between catchments. These slow-flowing habitats allowed many lowland species to thrive and this is reflected today in the fish community structure in some rivers. The problems to barriers to the movement of migratory species imposed by dams and weirs and the efficacy of compensation measures are discussed. The latter embrace fish passes, adult fish and smolt transport, and stocking. Potential problems for the future include the disruption of the homing of salmon to their natal rivers caused by transfers of water between catchments.1988 Issn 0886-9375 English Journal Article ASFA 1: Biological Sciences & Living Resources; Pollution Abstracts; Health & Safety Science Abstracts; Ecology AbstractsAHBEnvironmental requirements of European non-salmonid fish in riversMann, R.

Hydrobiologia2 323,3r223-235of_There is much evidence to show that the bottlenecks to recruitment in many non-salmonid fish populations relate principally to spawning success and to the growth and survival rates of newly-hatched larvae (Mills & Mann, 1985). This review deals with these parts of the life-cycle, together with the habitat requirements of adult fishes and the wider aspects of fish community structure. The review concentrates on the most common European species, especially those that are of commercial or angling importance (Table 1). However, data on habitat requirements are available for only some of these 32 species. 1996recruitment; freshwater fish; spawning; environmental conditions; Europe; Pisces; habitat selection Freshwater Q1 01344 Reproduction and development; D 04668 Fish|u1996 Issn 0018-8158 English Journal Article; Review ASFA 1: Biological Sciences & Living Resources; Ecology AbstractsCN@:Pavlov, D.S.

Various hydraulic regimes were created in the lower water race of the model with the help of the gates of the model itself. The current depth in the lower water race of the hydrosystem comprised 0.08 m. Current hydraulic characteristics seen to be involved in the production of routes of fish movement in a current included the longitudinal velocity component, the turbulence intensity, and the transverse gradient. The data obtained was used to develop a method for predicting the entrance of fish into the fish-passing structures.  Payne, B. S. Miller, A.

In general, conditions were too erosional just below and too depositional just above the locks and dams to support substantial populations of mussels. The only substantial community found was at a site designated as A3, at river mile 649.2 to 649.5 above Lock and Dam 9. Nineteen species of unionids were represented among 629 individuals collected at this location. A low-density assemblage (2 to 11 individuals/m2) occurred at the upper and lower ends of Site A3. The endangered species Lampsilis higginsii comprised approximately 0.3 percent of the mussel community at Site A3. The estimated density of L. higginsii equaled 0.02 individual/m2. This density value was slightly less than the range of densities (0.04 to 0.23 individual/m2) that have been estimated for the least dense populations of species that have persisted in several other large-river mussel beds. Thus, the density of the L. higginsii population at Site A3 may be slightly less than the minimum required for a reproductively viable population.  D  E     *  +    & 2 ~xMISC. PAP. U.S. ARMY ENG.

Early growth of paddlefish determined from back-calculation of annular measurements on dentary cross sections was high relative to paddlefish populations in the Upper Mississippi River drainage; lengths of age-1 fish ranged from 411 to 455 mm in eye-fork length. Natural mortality of Louisiana paddlefish was high (26-48%), and data suggested a reduction in age at maturity (100% females mature at age 10), lower fecundity (average fecundity, 9,500 eggs/kg body weight), and larger eggs (average diameter, 2.67 mm) relative to other paddlefish populations. Changes in reproductive life history characteristics may reflect rapid growth and high natural mortality rates. As the postmoratorium commercial fishery for Louisiana paddlefish develops, conservative harvest regulations should be promulgated until the effects of harvest on paddlefish stock dynamics can be determined.  o  tm1992 Issn 0002-8487 English Journal Article ASFA 1: Biological Sciences & Living Resources; Ecology Abstractsa#2,Moen, C.

Thirty-two large fish (6.3-25.4-kg) implanted with radio transmitters were located an aggregate of 812 times during March-August 1988, and spring 1989. No relation could be discovered between changes in river stage or discharge and direction of movement. No tagged paddlefish moved upstream from Pool 13, but during 1988 six fish moved downstream into Pool 14. Rates of movement were not significantly different between sexes, but the linear range for females was twice that of males. The greatest linear distance a paddlefish moved was 92 km downstream, and the greatest cumulative movement--entirely within Pool 13--was 435 km; both records were set by females. Nearly three-fourths of all contacts with paddlefish occurred in about 5% of available habitat in Pool 13. Paddlefish were located most frequently at the head of Pool 13 in the tailwaters below Lock and Dam 12. Even though the gates of Lock and Dam 12 were fully open in 1989, fish did not move upstream into Pool 12. The fish also commonly used main-channel borders with wing dams but rarely used backwaters or side channels. Water depth and velocity in areas used by paddlefish were generally within the optima suggested by current habitat suitability models, but water temperatures were usually greater than optimum.e I Z 1992 Issn 0275-5947 English Journal Article ASFA 1: Biological Sciences & Living Resources; Ecology Abstracts; Animal Behavior Abstracts\VFish passage facilities and anadromous fish restoration in the Connecticut River basin.(Moffitt, C.

However, it is believed that further possible uses may be realised as the potential of the species becomes apparent. Grass carp could be cultured as a food fish, having the advantages of being palatable rapid growing, cheap to feed and tolerant to handling and adverse environment conditions. As they are difficult to spawn in warmer climates, a demand exists for fingerlings throughout the tropics. They may also be used in New Zealand for protein reclamation systems. Grass carp may have potential roles in New Zealand for environmental protection, food production, and possibly as export earners.

The response of the two species differed. R. retropinna recruitment apparently failed during the "high impact" phase of C. idella stocking (44 fish ha super(-1)), when all aquatic weeds were removed. Immature fish disappeared and samples comprised 100% large females. G. cotidianus also increased in size, however, condition improved and the sex ratio did not alter markedly. Following reduction in C. idella stocking density, some return of population meristics toward prestocking values occurred.

Swimming performance within a hydraulic flume was measured and observations made of the behavioural adaptions of some species to swim through high water velocities. Timed swimming at known water velocities allowed estimation of critical velocities for fish passage. For juvenile fishes (30-80 mm total length), velocities below 0.3 m/s should allow unrestricted passage over obstacles less than 15 m in length. Water velocities below 0.25 m/s may be necessary for obstacles over 15 m.e  y          |u1989 Issn 0028-8330 English Journal Article ASFA 1: Biological Sciences & Living Resources; Animal Behavior Abstractsd,`Mukherjee, A.

This resulted in considerable fall in fish productivity in the river system. In most of the hydraulic structures, although different types of facilities (fish ladders, fishways, fish locks) have been provided to enable the fish to migrate upstream past the obstacles, it is reported that majority of the devices are hardly usable for the migrating fish. This is because of empirical design of most of the devices where due consideration has not been given to the performance and behaviour of the fish species that would utilise the pass for ascending upstream. Some preliminary observations made on the utility and effectiveness of the fish locks provided in the Farakka Barrage and their role to pass fish upstream over the barrage, having a rather wide range of heads, are presented.Conference Symp. on the Impact of Current Land Use Pattern and Water Resources Development on Riverine Fisheries, (Barrackpore (India)), 25-27 Apr 1987 SYMPOSIUM ON THE IMPACT OF CURRENT LAND USE PATTERN AND WATER RESOURCES DEVELOPMENT ON RIVERINE FISHERIES.

Paddlefish eggs were collected 5.6 km downstream from Cordell Hull Dam beginning 13 April, and larvae were found beginning 21 April 1977. No paddlefish eggs or larvae were collected in the Caney Fork River, presumably because the low temperature (11-11.5 C) of the Center Hill Dam discharge prevented spawning there. No paddlefish greater than 18 mm total length were taken by larvae sampling gear, and gill nets were ineffective in capturing young of year and yearlings. Paddlefish from 50 mm to 400 mm total length, however, were impinged on the intake screens at the Gallatin Steam Electric Plant on Old Hickory Reservoir in large numbers (approximately 9000 from August 1975 to May 1976). Comparisons of lengths on capture dates with similar data reported in the literature demonstrated that the impinged paddlefish were young of year which attained approximately 300 mm total length by age I.    haUsing Smart Source Parsing English Journal Article ASFA 1: Biological Sciences & Living Resourcese  Pasch, R.

Paddlefish moved about twice as much during night than day. Movement rate of paddlefish was related to reservoir water level, inflow, and discharge from the reservoir at night; however, none of these variables was significant during the day. Location in the reservoir (distance from the dam) was negatively related to water level and positively related to inflow during day and night periods. Location in the reservoir was negatively related to discharge during the day. Paddlefish avoided the highest available water temperatures, but did not always avoid low dissolved oxygen concentrations. Paddlefish avoided the Cimarron River arm of the reservoir in summer, possibly because of high salinity. Our study demonstrates that distribution of paddlefish during summer and movement in Keystone Reservoir was influenced by physicochemical and hydrologic conditions in the system. However, biotic factors (e.g., food availability) not measured in this study may have been influenced by abiotic conditions in the reservoir.a  & xqJun 2000 Issn 0038-4909 English Journal Article Ecology Abstracts; ASFA 1: Biological Sciences & Living Resources; :$O'Connell, M.

To protect and guide fish from entrainment, devices such as closely spaced bar racks (angled or straight), louvres, curtain walls and netting have been used. Breaches, weirs, notches, chutes, pipes, multiple entrances and plunge pools are other features considered in the design development of downstream fish passage facilities. Critical elements of the design process include flow approach, attraction flow, behavioural guidance devices, bypass location, conveyance mechanism and plunge pool conditions. This chapter discusses the developments in design criteria for downstream fish passage facilities at hydroelectric sites in the north-east part of the USA. Targeted anadromous species include Atlantic salmon Salmo salar, American shad Alosa sapidissima, blueback herring Alosa aestivalis, and alewife Alosa pseudoharengus. Bioengineering perspectives on the design criteria, type of fish protection used and examples of existing facilities are offered.B  }        Conference Fish Migration and Fish Bypass Channels Symp., Vienna (Austria), 24-27 Sep 1996 Fish Migration and Fish Bypasses, Fishing News Books, 1998, pp. 267-280 Price: pound sterling 65.

L. 2001BOne of the most important characteristics of a stream is the degree of its turbulence. In fish motion the critical current velocity equals the minimum current velocity that exhausts a fish. In order to increase the range of change in the turbulence intensity in the stream, a system of races was created above the upper net with the help of a submerged hydraulic spring, acting as a generator of elevated turbulence. Young roach were used in the study. A stream with a higher degree of turbulence possesses a greater kinetic energy for fish. Therefore, the energy expenditures of fish will be higher in such currents, leading to a decline in the critical current velocity. The findings should be taken into account in the control of fish behavior. An increase in the degree of turbulence in active fishing equipment, such as a trawler, will promote the most rapid exhaustion of the fish and an increase in the catch. At the same time an increased stream turbulence in the fish tanks of fish-passing structures is undesirable as it will result in the loss of fish to the current.d4 JDPeake, S. Beamish, F.W.S.

Data will be used to analyze impacts of construction and operation of a new lock and dam at River Mile (RM) 964.4. The greatest focus has been on a mussel bed just downstream of the project. Density categories of <20, 20 to 50, and >50 individuals per square meter are reasonable for delineating low-, moderate-, and high-density assemblages within this bed. Density >200 individuals per square meter is occasionally measured, but always describes a location heavily dominated by recent recruits. The native mussel community of the Lower Ohio River is dominated by Fusconaia ebena. Dominance of this species was high at RM 967 (near Olmsted, IL), typically exceeding 80 percent of the community. At RM 957 (near Post Creek, IL), F. ebena is much less dominant (33 percent). Species richness is similar at both locations. The F. ebena population in the Lower Ohio River is heavily dominated by a single-year class (probably 1990) of recent recruits. Prior to the exceptional recruitment in 1990, this population was dominated by a very abundant 1981 cohort. 3 B   7 ? f`, Sep 1998, 95 pp. Report: WES-TR-EL-98-12.

Of these freshwater species, the latest (1989) analysis indicates that six can be classified as endangered, five as vulnerable, four as potentially threatened, two as indeterminate, 32 as restricted, and 16+ as of unknown status, totalling 65+ species. Thus approximately 34% of the entire Australian freshwater fish fauna falls within the above six conservation status categories. Conservation problems of these fishes, and particularly man-made changes to their habitats, are discussed, and some possible management solutions outlined. Brief mention is also made of several marine species which may also fall into one or more of the above conservation categories, although not enough information is yet available to classify them accurately..(Conference The Biology and Conservation of Rare Fish: FSBI Symp., Lancaster (UK), 16-20 Jul 1990 1990 Issn 0022-1112 English Journal Article; Conference; Review ASFA 3: Aquatic Pollution & Environmental Quality; ASFA 1: Biological Sciences & Living Resources; Oceanic Abstracts; Ecology Abstracts Power, G. 1989One rung at a timeAtlantic Salmon Journal381 30-32.(anadromous migrations; resource conservation; guiding devices; design; specifications; anadromous species; Salmo salar fishways Marine; Freshwater Q5 01522 Protective measures and control; Q5 01523 Conservation, wildlife management and recreation; O 4090 CONSERVATION AND ENVIRONMENTAL PROTECTIONThe author describes the four basic categories of fishways; the pool and step (or weir), the Denil, the vertical slot and the fish elevator.vp1989 Issn 0044-992x English Journal Article ASFA 3: Aquatic Pollution & Environmental Quality; Oceanic Abstracts0*Power, M.

Therefore, "one-size-fits-all" prescriptions cannot substitute for local knowledge in developing prescriptions for dam structure and operation to protect local biodiversity. One general principle is self-evident: that biodiversity is best protected in rivers where physical regimes are the most natural. A sufficiently natural regime of flow variation is particularly crucial for river biota and food webs. We review our research and that of others to illustrate the ecological importance of alternating periods of low and high flow, of periodic bed scour, and of floodplain inundation and dewatering. These fluctuations regulate both the life cycles of river biota and species interactions in the food webs that sustain them. Even if the focus of biodiversity conservation efforts is on a target species rather than whole ecosystems, a food web perspective is necessary, because populations of any species depend critically on how their resources, prey, and potential predators also respond to environmental change. In regulated rivers, managers must determine how the frequency, magnitude, and timing of hydrologic events interact to constrain or support species and food webs. Simple ecological modeling, tailored to local systems, may provide a framework and some insight into explaining ecosystem response to dams and should give direction to mitigation efforts.|Dec 1996 Issn 0364-152x English Journal Article Water Resources Abstracts; ASFA 3: Aquatic Pollution & Environmental Quality "Powers, P.

A systematic classification system is developed which defines the geometric and hydraulic parameters for a given stream discharge. This classification system is organized in a format can be used to catalog barriers in fisheries enhancement programs.

White suckers Catostomus commersoni , walleyes Stizostedion vitreum , and saugers Stizostedion canadense made up 93.0% of the run. At Cowan fishway four species caught were white suckers, longnose suckers Catostomus catostomus , northern pike Esox lucius, and walleyes; 11,294 fish were trapped, although it was estimated that over 23,000 fish passed through the fishway. The size range of fish that passed through the fishways was 212-800 mm. The longest Denil fishway section negotiated was 9.5 m at a 12.6% slope. Headwater levels, water depths and water velocities were monitored. Although fish movements at both sites were likely obstructed by dams for several decades, all species present ascended the fishways readily..

The large amount of data available, although primarily from laboratory respirometer studies and unevenly distributed between species, offered an opportunity to consider its systematic application to the development, design and testing of such devices. With this motive, comprehensive searches were made and literature on fish swimming performance tests was compiled, and published data were entered on spreadsheets. This data base includes the following information: scientific and common fish species name, swimming mode, fish length (l in m), swimming speed (U in m/s), endurance or time to fatigue (t in s), water temperature during testing, life stage (e.g. juvenile or adult), test method (e.g. constant or increasing velocity), number of fish tested, regressions of swimming speed versus fish length for specific endurance times as reported in the literature, publication reference (author and date), and relevant comments (Katopodis and Gervais 1991).

Hansen's analysis has successfully reproduced our equations for designs 1 and 5. We would like to point out that for turbulent free surface flows over roughness elements of the type encountered in culvert fishways (discussed in the paper), the depth measurements are necessarily approximate and subjecting these approximate depths to a very refined analysis is perhaps not warranted. We established the flow parameters Q sub(*) and y sub(0)/D not from purely data correlation but from sound fluid mechanics. Having established a functional relationship between these (compound) parameters, we wanted to evaluate this function for the different designs. The simple power law relations were developed primarily by plotting the data on double-log sheets and fitting a line by judgement, giving more weight to regions of more importance.

On the other hand, the fish baffles did not perform as well as the fish weirs under the conditions tested.(lfDec 1990 Issn 0315-1468 English Journal Article ASFA 2: Ocean Technology Policy & Non-Living Resources4d,.(Rajaratnam, N.

Six designs with two baffle heights and three spacings were tested. A flow equation has been developed to predict the flow depth for any given discharge, diameter, and slope. The barrier velocity that would exist at the slot in the baffles has also been predicted in a general manner. This relatively simple slotted-weir baffle system has been found to match the performance of the more complicated but frequently used offset baffle system of similar dimensions.1989 English Journal Article ASFA 2: Ocean Technology Policy & Non-Living Resources; Oceanic Abstracts; ASFA 3: Aquatic Pollution & Environmental Quality}vD"Ward, J.

According to the SDC, dams result in upstream-downstream shifts in biotic and abiotic patterns and processes; the direction and extent of the displacement depend on the variable of interest and are a function of dam position along the river continuum. As originally formulated, the SDC did not consider interactions between the river and its floodplain. The new perspective presented herein is an initial attempt to encompass the dynamics of alluvial flood plain rivers into the model using a three reach characterization: constrained headwater reach, braided reach and meandering reach. The constrained headwater reach has conditions similar to those described in the original SDC, but the braided and meandering reaches provide a perspective that was not addressed in the model. Lateral interactions between the channel and the flood are critical to a holistic understanding of natural river ecosystems and the alterations induced by regulation. The fringing floodplain, with its diverse water bodies and alluvial forest mosaic, is considered an integral part of the river system.Conference 6.

These waves run more slowly than the waves of muscle activation causing them, reflecting the effect of the interaction between the fish's body and the reactive forces from the water. The coupling between both waves depends on the lateral body shape and on the mechanical properties of the tail. During steady swimming, the length of each myotomal muscle fibre varies cyclically. The phase relationship between the strain (muscle length change) cycle and the active period (when force is generated) determines the work output of the muscle. The muscle power is converted to thrust either directly by the bending body or almost exclusively by the tail, depending upon the body shape of the species and the swimming kinematics. We have compared the kinematics and muscle activity patterns from seven species of fish with different body forms and swimming modes and propose a model which yields a consistent pattern, with at least three extremes. Subtle tuning of the phase relationship between muscle strain and activation cycles can lead to major changes in the way muscles function in different swimming modes.i`Z1995 Issn 0022-0949 English Journal Article ASFA 1: Biological Sciences & Living ResourcesV p&Farlinger, S.

Such discrete populations would make identification and management of evolutionarily significant units (ESUs) straightforward. However, in contrast to this prevailing restricted movement paradigm, recent evidence indicates that even resident salmonids, such as interior stocks of cutthroat trout Oncorhynchus clarki living in headwater streams, move often, sometimes over relatively long distances. Resident stream fishes likely move in response to various ecological constraints, including the need to garner enough scarce resources or find a critical resource, or because the habitat they occupy becomes suboptimal or unsuitable. This emerging paradigm shift has important implications for defining and managing ESUs of resident stream fishes. For example, timing of sampling may affect which of several different "populations" mobile individuals are chosen to represent. Isolating small populations of native fishes above barriers to prevent invasion by exotic species may trade this risk for other environmental, demographic, or genetic risks caused by eliminating dispersal. Moreover, isolating small population fragments via natural or anthropogenic disturbances, or management actions, may create artificial ESUs. Biologists must understand not only the genetics and taxonomy, but also the spatial and temporal dynamics of component populations of species if they are to accurately identify and wisely manage ESUs.

The effect of a high (6.5 m) and a very low obstacle (40 cm) on the fish fauna in two Swiss rivers was documented. A considerable loss of fish species was observed in stream reaches above the barriers. Surveys of small artificial barriers in several Swiss river systems demonstrate the density of these potential migration obstacles. Movements of brown trout Salmo trutta and rainbow trout Onchorhynchus mykiss were shown over diel, seasonal and an annual time scale using radio-telemetry. Non-salmonid fish species, typically thought of as resident, also undergo extensive movements and therefore depend on barrier-free streams to maintain their distribution. Like salmonids, cyprinids and small-sized fish species depend on an intact river corridor that allows migration, habitat shifts and survival of the population. In order to maintain and restore biodiversity, there is an urgent need to restore the longitudinal integrity of running waters.

In the southern coastal areas of New South Wales, a survey was undertaken to identify and document fish passage obstructions. The 254 obstructions documented included high dams, farm dams, fixed crest weirs, rock weirs, culverts, causeways, bridges and tidal floodgates, with causeways and culverts being the most common structures to obstruct fish passages. A fishway priority scheme was developed to provide a quantitative, objective basis to rank the priority of a fish passage restoration project for any obstruction, either by building a fishway or removing the obstruction. The evaluative criteria used include the size of the river system, location of the obstruction, presence of threatened species and the severity of the obstruction.N.S.W. Fish. Final Rep.

The complex had caused a significant reduction in the spawning area, with a deleterious effect on the reproductive cycle of the native species. An experimental model of a fish migration channel was installed, having a system of 'tank steps' at the foot of the dam, a sheet-metal ladder, a serpentine-style channel for the spawning of the fish, and two marginal lagoons for incubation of the eggs and growth of the larvae. The return migration of the hatchlings will be made through a trough linking the marginal lagoons directly to the Parana River. The first phase of the project is formed by a 56-m-long ladder. Preliminary data from the first phase has proved that fish (3000/day) of tropical climates can ascend ladders exceeding 8 m. The results of the first phase indicate the efficiency of the experimental project, with the entry and ascendancy of fish in a migration channel ladder. These data now provide the technical basis for implementation of the complementary spawning channel stage.International Water Power and Dam Construction IWPCDM, Vol. 45, No. 5, p 24-25, May 1993. 1 fig, 2 ref.

The results show that some species of fish can ascend the latter during the migratory period; the dam is non-selective with respect to species, but selective with respect to fish size as a result of the presence of reduced openings. The ladder was ascended by both scaly species from surface waters (agile movers) and by deep water species which were characterized by slow movements. An average of 2892 fish ascended the ladder each day. The weight and length of fish recorded ranged from 336.0 to 3676.0 g and from 30.2 to 71.3 cm, respectively. The largest group of migrating fish was the curimba Prochilodus scrofa. The high ratio of 72% of fish in the gonadal development stage, classified as "maturing", indicates that the species caught in the ladder were migrating for reproduction purposes.s , > 1994 Issn 0886-9375 English Journal Article Ecology Abstracts; ASFA 1: Biological Sciences & Living Resources; ASFA 3: Aquatic Pollution & Environmental Quality; Water Resources Abstractse  I    i P3)ap & 8 >@ C   L*h    + ^  h  :?

This two-day immersion in the status of Acipenseriformes left participants feeling cautiously hopeful about the future of North American sturgeons and paddlefish but also deeply pessimistic about the prospects for most of the Eurasian species. In the United States, interest appears high in conserving sturgeons and paddlefish, and each species is receiving federal protection or intensified state management. Most worrisome is the status of the extremely rare Alabama sturgeon Scaphirhynchus suttkusi, which only occurs in the Mobile River system. Also of concern is the scarce pallid sturgeon, which shows strong morphological indication of introgression with the shovelnose sturgeon Scaphirhynchus platorynchus, possibly due to habitat modifications in their native Mississippi River system. The situation in Europe and Asia is far more grim. European sea sturgeon Acipenser sturio once ranged widely along coastal Europe and Scandinavia; today, only marginal populations exist in the Gironde River, France, and possibly the Black Sea. Beluga Huso huso, which occurred in many of the major rivers and seas of eastern Europe and Russia, now has limited natural reproduction. Only a few adults of the Chinese paddlefish Psephurus gladius have been seen annually in the Yangtze River in recent years. Dabry's sturgeon Acipenser dabryanus, also limited to the Yangtze River; the Adriatic sturgeon Acipenser naccarii; and the Amu-Dar shovelnose sturgeon Psuedoscaphirhynchus kaufmanni of the Amu-Darya River are all in sharp decline or near extinction.t     ; K       K ]   1995 Issn 0363-2415 English Journal Article ASFA 1: Biological Sciences & Living Resources; ASFA 3: Aquatic Pollution & Environmental Qualityu{2rlBenke, A.

The importance of floodplains and the role of dissolved organic matter have not been adequately incorporated into our understanding of stream bioenergetics. We need to determine if some generally applicable organismal-environmental relationships can be used to predict energetic characteristics across streams. Major new initiatives are required to answer some of the larger scale questions. Several approaches are possible: (1) synoptic analysis of multiple streams to compare within-region variance with between-region variance, (2) experimental manipulation of entire streams or their catchments to test factors that control bioenergetics, (3) the use of batteries of experimental streams to help isolate cause-effect relationships, and (4) the further development of computer models that incorporate abiotic forcings and bioenergetics.

Walleyes Stizostedium vitreum vitreum dominate the sport fishery of the lake and migrate through the dam, providing a major tailwater fishery. Anglers caught 6042 walleyes from the lake and 8724 from the tailwater during a 1-year period. Walleye fishing success was higher in the tailwater than in the lake (0.56 vs. 0.32 caught per hour). Walleye fishing success was highest during the fall in the lake but during the spring in the tailwater. Tag returns indicated a 6% exploitation rate for lake walleyes during a 15-month period. Tailwater walleyes experienced a 25% exploitation rate during a 7-month period. Nine percent of walleyes tagged in the lake were caught by anglers in the tailwater from December through March. Age-0 and Age-1 walleyes migrated through the dam more readily than older walleyes. Walleye migration occurred during the winter, December through April, at times when the pool elevation was decreasing at a rate of at least 6-ft per 24 hours.9   Reservoir Fisheries Management: Strategies for the 80's.

High variability in counts within day and season required more intensive sampling than suggested by previous studies to estimate the population mean to within a given percent relative error. Stratification in some cases doubled or trebled the precision of the estimated mean relative to the mean obtained from simple random sampling, whereas systematic sampling produced no gain in precision. Stratification to reduce the number of sample units required for a given precision may reduce the power of a test to detect differences between annual estimates of population means, depending on their variances. The importance of these interrelated factors should be determined before a particular scheme and level of effort are chosen for sampling.e ! 5 1990 Issn 0275-5947 English Journal Article ASFA 1: Biological Sciences & Living Resources; Oceanic Abstracts; Ecology Abstracts Warren, M.L.

The United States harbors the most diverse temperate fish fauna in the world with about 790 species represented, about 90% of which are nongame fishes. From a state-by-state perspective, diversity of fishes in the United States is concentrated in the South, primarily in Alabama, Kentucky, Georgia, Mississippi, Tennessee, and Virginia, each of which supports at least 200 native fish species. Endemicity of fishes is high in both the South and West; in the latter region, up to 70% of the fishes in some drainages (e.g., Colorado River) are endemic. Imperilment apparently is not confined to particular taxonomic groups. Of the five most diverse fish families in the United States, total imperilment ranges from 7% in the Centrarchidae to 50% in nonanadromous salmonids and indicates widespread and pervasive degradation of aquatic habitats. Imperilment is most accute in areas of high diversity and / or endemicity (i.e., the southern and western states). States with 20 or more imperiled fishes include Alabama, Arizona, California, Georgia, Nevada, New Mexico, North Carolina, Oregon, Virginia, Tennessee, and Texas. Backlogs in listing species as federally threatened or endangered are most egregious (10 or more backlogged taxa) in Alabama, Georgia, Nevada, and Tennessee.HWatters, G.

On a large river system scale, the number of unionid species is directly related to the number of fish species present and, to a lesser extent, the drainage area. In small systems, such as headwater tributaries, the number of unionid species is related to the drainage basin area. Unionid diversity in systems intermediate in size may be related to both. This may be the result of transient fishes in small streams depositing glochidia. The overall distribution and diversity of unionids within the study area is dependent upon the distribution and diversity of their fish hosts.tm1992 Issn 0305-0270 English Journal Article Ecology Abstracts; ASFA 1: Biological Sciences & Living Resourcesvd <5Lubinski, K.

Research related to the development of water level management plans is being conducted under the Long Term Resource Monitoring Program. Research strategies include investigations of cause-and-effect relationships, spatial and temporal patterns of resource components, and alternative problem solutions. The principal hypothesis being tested states that water level fluctuations resulting from navigation dam operation create less than optimal conditions for the reproduction and growth of target aquatic macrophyte and fish species. Representative navigation pools have been selected to describe hydrologic, engineering, and legal constraints within which fish and wildlife objectives can be established.

The objective of the conference 'Sustaining the Ecological Integrity of Large Floodplain Rivers: Application of Ecological Knowledge to River Management', was to provide presentations of current ideas from the scientific community. To translate the many lessons learned on other river systems to operational decisions on the UMR, a companion workshop for managers and the general public was held immediately after the conference. Regardless of authority or responsibility, management agencies supported the conference and workshop for the purpose of providing state-of-the-science ecological guidance.

Radio telemetry was used to monitor the movements of 18 sturgeon. An additional 165 sturgeon, captured by gillnets, provided information on spawning site selection, sex ratio, and reproductive condition. For 3 years the mean water velocities during the spawning period ranged from 0.36 to 1.2 m sec-1 in the spawning area. Substrate was cobble and rubble. Sturgeon spawned over a short time period (3-5 days), during decreasing river discharge of 679 to 301 m3 sec-1 and rising water temperature between 11.5 to 14.0 oC. High river discharge over a prolonged period during the normal spawning season may preclude reproduction.n  G ]    y  z ~      Conference Symposium on Biology and Management of Sturgeon (at) 113.

Mark-recapture and radiotelemetry were used to assess attraction and fish passage. Movement of 85 radio-tagged fish was monitored continuously during spring and early summer of 1995 and 1996. Attraction and passage efficiencies of white suckers at the west fishway were approximately 50%, and 55%, respectively. Attraction efficiency of white suckers at the east fishway was approximately 59%, and passage efficiency was 38%. The attraction and passage efficiencies of smallmouth bass at the west fishway were approximately 82% and 36%, respectively. At the east fishway, attraction efficiency of smallmouth bass was approximately 55%, and passage efficiency was 33%. There was an exponential decline in the numbers of both species that used each fishway relative to water velocity. The maximum water velocity used by white suckers was 0.96 m/s and that used by smallmouth bass was 0.99 m/s. Distracting flows near the west fishway appeared to affect attraction. Both fishways passed equal numbers of smallmouth bass per year, and smallmouth bass that used the east fishway were significantly larger than individuals that used the west fishway. In contrast, more than twice as many white suckers used the west fishway, and these fish were significantly larger than those that used the east fishway. Differences in passage were related to burst and critical swimming speeds and the use of velocity refugia within the fishways.c     Aug 1999 Issn 0275-5947 English Journal Article ASFA 1: Biological Sciences & Living Resources; ASFA 3: Aquatic Pollution & Environmental QualityiOfOrJ Dominy, C.

The mean rate of passage of alewives from pool to pool within the fishway (37.59/min) was not significantly greater or less than the mean rate for either of the entrance weirs. Density tests at two intermediate fishway pools revealed that the relationship between alewife density and exit rate may be described by a curve that rises to a peak exit rate of 80/min at a density of 75m3 and then levels of to 70 /min at higher densities. It is concluded that crowding and delay is not likely to occur within the fishway at the peak of the alewife run. Values for substitution in the formula of Clay (1961) for calculating fishway capacity determined for the alewife show that this species does not require any more time per fishway pool than Pacific salmon and that the demands of alewives on water volume are about six times less than for Pacific salmon. These determinations permit more general application, by fisheries resource biologists and engineers, of the data presented on crowding, delay and capacity for alewives in a pool and weir fishway. 1 E      Duncan, R.

The primary objective of this survey was to quantitatively define the diversity and relative density of the mussel community in Pool 10 of the river. Pool 10 extends from Lock and Dam No. 9 near Lynxville, Wisconsin, to Lock and Dam No. 10 at Guttenberg, Iowa , a total of 32.8 river miles. Of the 309 sites sampled, mussels were found at 224 sites, or 72%. The East Channel near Prairie du Chien, Wisconsin had the richest mussel fauna with an average density of 2.964 mussels per square foot; and only 6% of the sites were nonproductive. The lower end of Pool 10 had the lowest mussel density at 0.655 per square foot and the highest percentage of nonproductive sites, 38%. The mussel density in the main channel border was two times greater than in the main channel and backwater. A total of 12,150 live specimens representing 31 species of freshwater mussels were collected from Pool 10; an additional 7 species were represented only by dead specimens. Threeridge, Amblema plicata, was by far the most abundant mussel species, comprising 52.9% of the catch and having an average density of 0.832 per square foot.  > M TMTechnical Bulletin No 139 1983. 14 p, 4 Fig, 2 Tab.

A 1984 law concerning freshwater fisheries requires that any obstruction in streams or parts thereof, in the list specified by decree, must include facilities to ensure the passage of migratory fish. As a result, more than 400 fish passes were built or improved, and significant advances in the design of upstream fish passage facilities have occurred during the last 15 years. This chapter provides an overview of the functional features and design parameters used in the different types of passage facilities: Denil fish passes, pool fish passes, fish elevators and natural bypass channels. The relative advantages and drawbacks of each type of fish pass are discussed, with reference to the requirements of specific migratory species and site-specific constraints. Emphasis is placed on the problem of maintenance. The various techniques used in France to evaluate the existing or newly constructed fish passes, as well as the topic of downstream migration at turbine intakes, are reviewed. Recent experiments have tested surface bypasses designed to provide a safe downstream route for smolts at small-scale hydroelectric plants. The efficiency of such bypasses is evaluated by radio telemetry and release-recapture tests. Results from some field studies are outlined. The effect of mercury lights to increase bypass attraction is discussed. The behaviour of fish in relation to the hydraulic flow patterns at the intake should be considered when designing a downstream bypass system. In conclusion, the author presents his view on the priorities for future research on fish passage facilities, insisting on the need for close collaboration between engineers and biologists, in particular fish behaviourists. Some priorities include the use of radio-telemetry to track Atlantic salmon Salmo salar on the migratory rivers, and research aimed at gaining a better understanding of downstream migration of salmon, brown trout S. trutta, and European eel Anguilla anguilla. q |    ' Conference Fish Migration and Fish Bypass Channels Symp., Vienna (Austria), 24-27 Sep 1996 Fish Migration and Fish Bypasses, Fishing News Books, 1998, pp. 127-146 Price: pound sterling 65.

A. Slaney, P. A. Fisheries2211 16-24Marine nutrients and carbon transported by adult salmon are important to the productivity of the oligotrophic lakes and streams in which salmon spawn. Reduced carcass availability results in a decline in nutrient and carbon sources for stream-rearing salmonids. We examined 42 years of escapement records for five species of Pacific salmon for Georgia Strait, the west coast of Vancouver Island, and the mainland coast of British Columbia to estimate the status of this nutrient source. Salmon stocks from enhanced streams frequently dominated the total escapement of entire regions. As a result, most of the influx of marine nutrients is focused toward a few large stream systems already undergoing significant salmon enhancement, while nutrient influx to the more-numerous unenhanced streams is declining. In the large number of streams with smaller salmon escapements, stream-rearing species already in decline may decrease further from oligotrophication. Risk-averse escapement targets for wild salmon stocks need to include sufficient spawners to provide the nutrient influx linked to the maintenance of stream productivity. Declining trends in nutrient influx to wild salmon streams in most regions are a cause for concern and more intensive examination. 1997ztNutrients (mineral); Carcasses; Anadromous species; Isotopes; Tracers; Biological production; Energy flow; Canada, British Columbia; nutrient concentrations; Salmonidae; Canada, British Columbia marine-derived nutrient influx; Salmonids Marine; Freshwater Q1 01482 Ecosystems and energetics; O 1070 Ecology/Community Studies; Q2 02185 Organic compounds; D 04700 ManagementNov 1997 Issn 0363-2415 English Journal Article ASFA 1: Biological Sciences & Living Resources; Oceanic Abstracts; ASFA 2: Ocean Technology Policy & Non-Living Resources; Ecology Abstracts[2 June, F.

The onset of vitellogenesis varied within species (up to 2 months). Maturation of the ova took from 7 . 5 to 10 months, depending on species. Annual variations in the mean date of peak spawning of individual species during 1964-71 were usually less than a week. There was little overlap of the annual mean peak spawning dates of the 17 species, and an established sequence of spawning among species was shown. A relatively high incidence of atresia in the shovelnose sturgeon, northern pike, and carp indicated that these species had apparently not yet adapted to the altered and variable spawning conditions in this reservoir. Regularity of spawning would seem to provide the best chance for spawning success in variable environments such as Lake Oahe.pjUsing Smart Source Parsing English Journal Article ASFA 1: Biological Sciences & Living Resources 20001231 Jungwirth, M. 1996ZSBypass channels at weirs as appropriate aids for fish migration in rhithral rivers.0)Regulated Rivers: Research and Management12483-49281weirs fishways fish passage bypass fish migrationi:In most cases, the design of currently deployed migration aids is based on technical concepts, e.g fish ladders, fish lifts, etc. These systems meet the swimming and migratory requirements of commercially interesting species such as salmonids, but not of a smaller fish species and/or juvenile stages. In this context, bypass channels designed to resemble natural stream channels-with a comparatively flat gradient and a high morphological, current and substrate diversity-are a viable alternative. The utility of such systems, in compensating for the interrupted river course and in supporting migrations of various rhithral fish species, has been demonstrated in an investigation of a bypass channel on the Mur River in Styria, Austria. This 200 m long system with a total of 30 pools and riffle-like connections was successfully navigated by all seven existing fish species and was additionally used by juvenile fish as habitat. During the main spawning periods April - June and September-December, a total of 3,658 fish ascended the bypass, 94% of which did so in the spring. In the 5.5 km stretch of river below the weir, the grayling Thymallus thymallus was the dominant species. From an estimated population of 13300 adults, 17% migrated through the pass. {   Jungwirth, M. 1998|vRiver continuum and fish migration- going beyond the longitudinal river corridor in understanding ecological integrity *#Jungwirth, M.

Restoring previously interrupted migratory pathways of fishes using bypass systems is one potential approach, but simply passing fish generally tends to overestimate the 'feasibility' and ultimate success of amelioration strategies in the framework of river revitalisation projects. This chapter attempts to show that running waters are far more than mere longitudinal river corridors. Modern concepts of ecology describe running waters as complex, four-dimensional systems. While longitudinal river corridors represent an important dimension, they are merely one of numerous factors whose interactions define ecological integrity. The long-term preservation and sustainable utilisation of running water ecosystems can therefore only be achieved by fully considering all four dimensions that contribute to overall ecological integrity.Conference Fish Migration and Fish Bypass Channels Symp., Vienna (Austria), 24-27 Sep 1996 Fish Migration and Fish Bypasses, Fishing News Books, 1998, pp. 19-32 Price: pound sterling 65.

The meeting was attended by a diverse group of engineers and biologists primarily involved in various aspects of fish passage design and evaluation, river restoration or the study of migratory fish. This publication contains the majority of the oral presentations in article format, together with some poster material extended into articles. Since the publication of Charles Clay's The Design of Fishyways and Fishpass Facilities in 1961, the joint efforts of hydraulic engineers and fishery biologists have led to tremendous improvements in the technical design and efficiency of a whole array of fish passage facilities, together with an increased understanding, at least for a handful of well-researched species such as anadromous salmonids, of the complexities of fish migration and behaviour important to fish passage. This research has reached perhaps its zenith in cost, scale and complexity with the passage facilities on a series of dams on the Columbia River in the north-western United States. Here, one can boast of passing adult salmon through a staircase of concrete and metal baffles, orifices and louvres with an elevation gain of 35 m across 1300 m of length in under 4 hours (Williams, Chapter 13).PIConference Fish Migration and Fish Bypass Channels Symp., Vienna (Austria), 24-27 Sep 1996 Fishing News Books, 1998, 438 pp Price: pound sterling 65.

A Denil fish pass on the Ampsin-Neuville dam was controlled 251 times in 1989-1993. The most striking feature is the almost complete absence of barbel. Most captures of barbel in the fish pass in 1989 were clumped and related with spawning migrations. The variables involved in the attractivity condition set refer indirectly to the influence of water catchment by a hydroelectric plant and to the relative importance of the flow in the pass. The study concludes that this additional condition set significantly interfere with the natural environmental stimuli triggering spawning migrations in barbel and questions the effectiveness of the thermally related reproductive strategy of the species.e a n 1994 Issn 0990-7740 English Journal Article ASFA 3: Aquatic Pollution & Environmental Quality; ASFA 1: Biological Sciences & Living Resources <6Barekyan, A.

To eliminate negative aspects of the operation of existing fishways, research and development studies were carried out to develop new promising designs and technological schemes of attracting, holding, and conveying spawners from the lower to the upper pool of a hydrologic development. The realization of these designs will make it possible to increase the number of fishes being passed to spawning grounds, to reduce injury during their conveyance from the lower to the upper pool, and to reduce the number of downstream migrants that pass into the upper pool. The main group of developments is aimed at increasing the duration of active attraction of fishes, i.e., attraction at speeds close to the optimal, by changing the technology of releasing fish into the upper pool. One of the possible ways of increasing the productivity of a fishway is to continuously attract fish with a constant current speed at the exit of the fish-holding chute. Also effective is to replace the exiting stimulating devices with netting requiring a reduction of the current speed in the fish-holding chutes during its movement by devices using an electrical field for fish stimulation. Use of these fishway designs will make it possible to increase the passage of spawners to spawning grounds and thereby to increase the number of valuable commercial fish species in inland water bodies.Hydrotechnical Construction HYCOAR Vol. 22, No. 7, p 384-388, January 1989. 5 fig, 7 ref.

The method of probit analysis, commonly used in dealing with bioassay data, was found to be suitable for determining times to 50% fatigue and in providing a measure of variance despite the presence of some erratic behaviour. For sockeye acclimated to 15 oC (mean length = 13.6 cm) the velocity at which 50% fatigued was 54.4 cm/sec of 4.0 lengths/sec (L/sec). The 5% and 95% fatigue velocities were 3.1 and 4.8 L/sec, respectively. Larger fish required longer exposure times for determining maximum sustained speeds, extending from approximately 120 min for fingerlings to 500 min for adults. Using the method of increasing velocity steps the effect of temperatures from 5 to 27.5 oC was examined. When acclimated to 15 oC fingerling sockeye exhibited only a 4% reduction in swimming speed at 10 and 20 oC. Temperatures above the lethal level caused a rapid decline in swimming ability approaching the extinction point at 27.5 oC.

The very turbulent nature of the flow in the fishways is described and extensive velocity measurements are presented. Velocity profiles in the centerline of Denil 1 and 2 are distinct and display characteristic shapes amenable to similarity analysis, while velocity profiles for Denil 3 are inconclusive in this respect. Depth averaged velocities through the fishways are found to be only 11% to 14% of the average velocities expected in rectangular channels of the same dimensions. Energy dissipation in the three fishways is high. For slopes of 20% or more the fishways are more efficient than a hydraulic jump in dissipating flow energy. At lower slopes, the fishways create flow resistance conditions that are similar to those of boulder-filled headwater streams. A semi-empirical method is developed for the design of Denil fishways involving a fluid friction coefficient.CAN. TECH. REP. FISH. AQUAT. SCI., no. 1145, 1983, 189 pp Incl. computer data.

Weir baffles without slots would be less expensive to build than slotted-weir baffles and would resemble a pool-weir fishway. Baffles with heights equal to 0.15 and 0.1 times the diameter (D) of the culvert were studied with longitudinal spacings of 0.5D and 1.2D. Equations were developed to describe the relation between the discharge, slope, diameter, and the depth of flow. Using these equations it was possible to predict the barrier velocity that would exist at the baffles. The performance of the weir baffles was found to be as good as that of the slotted-weir baffles or slightly better by producing larger depths for smaller flow rates. A spacing of 0.6D was very effective, whereas a spacing of 1.2D appeared to be somewhat too large. During low flows, sediment may settle in the pools, but this might be eroded and transported by larger flows. A certain amount of maintenance of the culvert may be needed.

The discharge of the fishway was modifiable. Most of the fish ascended in the smallest test discharge. Improper energy dissipation, high drops between pools (20-30 cm), high velocities (over 1.4 m/s) and swirling of the water in the pools delayed or prevented the passage of vendace and whitefish. Water velocity at the most favourable resting areas corresponded to 1/2-1 fish body lengths per second (Bls-1), but even areas with a velocity of 2-4 Bls-1 were used. Although the pool dimensions were similar, there were differences in the flow characteristics of the pools and slots. Certain pools seemed to be popular at each discharge rate, in some pools the flow conditions changed remarkably between discharge rates affecting the behaviour of the fish. Learning played an important role as the fish ascended the fishway.d  * 8 D F R T ` t  k  m    1990 Issn 0356-7133 English Journal Article ASFA 1: Biological Sciences & Living Resources; ASFA 3: Aquatic Pollution & Environmental QualityoH & De Carvalho, J.

In the lower Tocantins, Brazil, two species of migratory fish dominate the captures: the mapara Hypophthalmus marginatus and the curimata Prochilodus nigricans. These species were studied before the damming of this river by the Tucurui hydroelectric dam as part of a larger study of commercial fisheries encompassing the Tocantins basin from the mouth to Maraba (Para). Based principally on landing records, this study describes the migration cycles of the two species. A classical and simple pattern of migration can be recognized: an upstream movement of immature forms and adults in the upper part of the distribution area, and the reverse or downstream movement of larvae and adults in a dispersion phase. The main difference between these two species lies in the size of the distribution area. The mapara is limited to part of the river downstream from the dam, and so would not be affected by its presence. The curimata has a much larger geographic range in the Tocantins basin. The part of the population living downstream will probably be profoundly perturbed by the dam due to the blockage of its migratory route.      vpAmazoniana Vol. 9, No. 4, p 595-607, June 1986. 8 fig, 5 tab, 18 ref.

No effects of dams on genetic variability were apparent in most places; this may be explained either by the permeability of dams to fish dispersal, by recent dates of isolation, and/or by the fact that the populations were large enough for genetic drift not to take place. However, a change in genotype structure caused by the dams may be suspected in the Lower Rhone. The chub and roach populations of the reservoirs and residual flow stretches show affinity with upstream lentic populations and not with upstream lotic populations as would be expected according to the mean gradient of their habitats. They are unstable populations in which extinction and colonisation from lentic upstream habitats presumably determine genetic structure.

Numerous studies have supported the restricted movement paradigm, but nearly all have relied on the recapture of marked fish from the same areas in which they were released, an approach we believe is biased against detecting movement. Substantial movement was found of trout in streams in Colorado and Wyoming using two-way weirs and radio telemetry. A review of the research on Lawrence Creek, Wisconsin, also showed that movement was important in the response of the trout population to habitat enhancement.

The round goby now has access to the Mississippi River system via the Grand Calumet River. Tubenose gobies (a small fish <120 mm) have only been found in the St. Clair River and Lake St. Clair, and maintain small to rare populations there. The round goby is much larger (up to 300 mm), is a multiple spawner, feeds almost exclusively on a relatively unutilized resource, zebra mussels, when it is >60 mm, and occupies depths to 10 m, but prefers nearshore areas. It has decimated populations of mottled sculpin and apparently depressed those of logperch in the St. Clair River, probably by driving competing species from prime feeding, security, and spawning sites. Many piscine predators eat gobies. Gobies are ideally suited for freighter transport because: (1) they can feed in the dark, (2) prefer holes or crevices, and (3) can tolerate degraded water quality conditions. We expect them to continue to spread and severely disrupt benthic fish communities in rocky, cobble, and vegetated areas, with the potential to also affect deepwater sculpin.kConference 38.

Because exotic species may be favored, a field experiment was designed to test differences in fish abundance in riprap, sand, and macrophyte-dominated substrate. A 3-m long seine was used to sample areas of sand, riprap and aquatic macrophytes three times during 1994 in the St. Clair River near Algonac, Michigan. Diversity was high, with 24 species of fish collected. Round gobies Neogobius melanostomus were most often collected in riprap and macrophyte habitat, with riprap habitat having a significantly greater mean catch on 16 August. On the other two dates, mean catches were not significantly different between macrophyte and riprap habitat, but both were significantly greater than the mean catch in sandy areas. Densities of tubenose gobies Proterorhinus marmoratus were similar between sandy and macrophyte habitats, but significantly greater in riprap habitat. Gizzard shad Dorosoma cepedianum, alewife Alosa pseudoharengus, and white perch Morone americana were mostly associated with open water sandy habitat.

A recent study by Mills et al. (1995) lists 139 species that have made a substantial impact on Great Lakes ecosystems and they include organisms from bacteria, such as furunculosis, through purple loosestrife Lythrum salicaria and Eurasian watermilfoil Myriophyllum spicatum, to fish. The transfer of these organisms was brought dramatically to the attention of businesses and the public with the discovery of zebra mussels Dreissena polymorpha in 1986 (Herbert et al. 1986) as water intakes became clogged, power plant pipes became plugged, and boats and motors became covered with this species. The homogenization of our aquatic communities, loss of biodiversity, and amalgamation of our gene pools because of the introduction of exotic species is a worldwide problem of which the round goby Neogobius melanostomus is just another symptom. The round goby Proterorhinus marmoratus, are our latest uninvited piscine immigrants joining Great Lakes fish communities. These fish are cyberfish, because they came from a distant universe and have the unusual ability to attain high abundances in optimal rocky substrate areas in the face of native fish communities and they also are able to disperse rapidly using Great Lakes freighters as transport vectors.  v    M a     tmApr 1997 English Journal Article ASFA 3: Aquatic Pollution & Environmental Quality; Water Resources Abstractsof F@Lucas, M.

The use of an automated flat-bed passive integrated transponder (PIT) antenna array to study the behaviour of fish at a Denil pass on the Yorkshire Derwent, North East England, is described. The array comprised four flat PIT antennae, each connected to a detector unit. Two antennae were positioned at the downstream end of the fish pass, and two at the upstream end. Each detector unit sent interrogation signals, received transponded signals from tags, and stored the data in a memory chip. Efficiency of the upstream detectors was validated as near 100% using tagged brown trout Salmo trutta introduced below the detectors and observed to swim past them. Between 22 May 1998 and 23 June 1998 a total of 284 fish, comprising 11 species with a combined length range of 9-95 cm, were PIT tagged and released downstream of the fish pass. Continuous recording between 23 May 1998 and 31 August 1998 demonstrated the effectiveness of the PIT array at this site, for recording entry to, and successful exit from the pass. A total of 160 separate entires from 36 different fish were recorded at the downstream detectors, and six fish successfully exited from the top of the pass, giving a pass efficiency of 16.7%, based on the proportion of different fish which passed. Overall 12.7% of tagged fish entered the pass, comprising chub Leuciscus cephalus, dace Leuciscus leuciscus, roach Rutilus rutilus, perch Perca fluviatilis, bleak Alburnus alburnus and brown trout.b            % - > d^Dec 1999 Issn 0165-7836 English Journal Article ASFA 1: Biological Sciences & Living Resources0*Lupton, C.

The physiological basis for the classification of swimming speeds is briefly explained with regard to burst, prolonged, cruising speed, and the velocity which is critical to fish. The protocols of fixed (fatigue) velocity tests and increased (incremental) velocity tests are reviewed. The experiments carried out by different authors are compared with respect to their methodological approaches, the main focus being on the different time intervals and velocity increments employed. From the comparison, it appears that time intervals between 2 and 75 min have been employed. Yet, it is shown that there is agreement that time intervals of longer than 15-20 min are not necessary if the critical velocity alone is needed. The dependency of the critical swimming speed (CSS) on factors such as race and population, size, season and temperature, sex, pollutants, light, food, training, and ambient gas content is outlined. The comparison shows that only the influence of pollutants and training on the CSS have been investigated in more detail, making further comparative studies on the dependence of the critical velocity on these factors necessary. Evaluation: since the CSS of fish depends on all these factors, it would appear to be a very sensitive measure for environmental or physiological factors. However, it is difficult to compare even intraspecific studies because of the individual variability and the dependence of swimming performance on the stock, population, gender and precondition level, making the calibration of the tests very complicated. It is shown that little is known about the mechanistic influence of internal or external factors on the CSS. Therefore, the CSS is of less interest for the physiologist than for the ecologist. Tests on the critical velocity have been successfully employed as an alternative to LD50 tests, although, once again, it is difficult to standardize the tests, and environmental factors, such as pollutants, may themselves influence the swimming performance since the metabolism can, in turn, in some cases depend upon the level of swimming performance itself.s t @v |u1995 Issn 0300-9629 English Journal Article; Review ASFA 1: Biological Sciences & Living Resources; Oceanic AbstractsHarden-Jones, F.R. 1968Fish Migration London (England) $Edward Arnold Publishers, Ltd. ???The author pursues a treatment of the biological aspects of migration in this early classical book on migration in fishes. Treatment is provided both environmental factors affecting migration as well as physiological adaptations that permit and aid fish migration. Means by which to study migration in fishes are presented and elucidated fully. The author then provides several "case history" examples of migration in fishes by discussing Salmonid, Anguillid, and Clupeid migrational strategies as anadromous examples. Two Gadiid examples, the cods and the plaice, are presented as examples of oceanic migration. Reactions to external stimuli, including temperature, current, chemical, and light, are presented based on findings from many scientific studies, both lab and field-based.cHaro, A.

American shad ascended and descended the fishway exclusively by surface weirs, while sea lampreys used both surface weirs and submerged orifices. Upstream movement of American shad during the day was higher than at night at both lower and middle fishway observation sites. Peak downstream movement of American shad at both locations was associated with decreasing light levels in the evening. Sea lampreys moved primarily at night at the lower and middle fishway sites. Mean daily passage efficiency was low (1% for American shad, -2% for sea lamprey) at the lower fishway surface weir, but passage efficiency at the middle fishway surface weir was moderate (70% for American shad, 35% for sea lamprey). High water velocity, air entrainment, and turbulence of the modified Ice Harbor fishway design appeared to inhibit American shad and sea lamprey passage by disrupting upstream migratory motivation and visual and rheotactic orientation.m - > O a Nov 1997 Issn 0275-5947 English Journal Article ASFA 1: Biological Sciences & Living Resources; Oceanic Abstracts; Ecology Abstracts; Animal Behavior Abstracts<C l6/Haro, A.

Percent of American shad passed per unit time (percent passage) increased with temperature, while time required to ascend from the fishway entrance to the exit (transit time) decreased with increasing temperature for both species. Increasing fishway slope decreased percent passage of American shad, regardless of fishway type. Higher fishway slope decreased percent passage of blueback herring in the steeppass fishway only. Low headpond enhanced percent passage of American shad in the Denil fishway, but decreased percent passage of American shad in the steeppass fishway. Headpond level had no effect on percent passage of blueback herring in either fishway. Because headpond level in the steeppass fishway affected percent passage of American shad but not the smaller blueback herring, the relatively small cross-sectional area of the steeppass fishway operated at low headpond may inhibit passage of larger species such as American shad. Transit time of American shad decreased with both increasing slope and high headpond, and American shad increased through-water swimming speed under these conditions. American shad appeared to regulate their swimming speed through Denil-type fishways below maximal values. Blueback herring ascended the fishways at speeds comparable to those of American shad. Shorter transit times were not associated with increased percent passage. Turbulence and air entrainment may influence percent passage of American shad more than longitudinal water velocity.

The results indicated that fish passage in about half of the aquatic habitat of Australia's south-eastern coastal drainages has been obstructed by dams, weirs and other man-made physical barriers. Migratory patterns of the region's fish species were reviewed. Ways in which impoundments affect the 26 species that were identified as migratory are discussed in relation to the ability of fish to bypass barriers, the nature of their migrations, and the role of flooding. The presence of about eight catadromous species in the region creates a special problem in fish passage. It is concluded that there is cause for concern over the status of the region's fish populations and that there is a need for a much greater awareness of the nature and extent of this problem.1984 Issn 0067-2238 English Journal Article Ecology Abstracts; ASFA 1: Biological Sciences & Living Resources; ASFA Aquaculture Abstractsl Harris, J.

Only 9.2% of 293 dams and weirs and 23 causeways surveyed had provision for fish passage. Among 37 fish species native to the study area, about 70% require passage within river systems, either for survival or for maintenance of population abundance and distribution. Despite this need for fish passage, the behavioural responses and physiological limits of Australian fish that control their use of fishways are poorly known. Of the 29 fishways recorded, 18 were of two metres or less in height, and none was higher than eight metres. Design, maintenance and water flow deficiencies resulted in 23 fishways failing to provide suitable conditions for fish passage at the time of the survey.tm1984 Issn 0067-2238 English Journal Article Ecology Abstracts; ASFA 1: Biological Sciences & Living Resourcesv \Kynard, B.

The purpose of the bypass was to enable downstream migrants that enter the canal to exit and avoid death due to delay or passage through hydroelectric turbines at water use facilities. The bypass system had the following elements: (1) an underwater AC electrical or acoustic barrier to prevent American shad from leaving the bypass area, (2) an underwater DC electrical field to immobilize fish for collection, and (3) a collection box with transfer pipe to carry fish to the river below the dam. During studies of the bypass system from 1979 to 1983, we found that the fish barriers were ineffective, the collection system was partially effective for American shad but not for anadromous species that passed through trashracks, and American shad could be immobilized and transported at high velocity through a pipe and have only low mortality (4-9%). Radio-tagged American shad, unwilling to pass through trashracks at water exits on the canal, behaved like trapped fish and were delayed an average of two or more days before dying or exiting the canal. An estimated 10 of 47 (21%) of the radio-tagged fish were passed. In 1980, when the greatest number of American shad were passed, an estimated 142,000 (37% of the fish lifted at the dam) survived spawning and used the bypass. After several years of operation, it was evident that, even with major improvements, the bypass could not pass the available American shad, and it was not useful for protecting other anadromous migrants that did not avoid trashracks. / @ 1993 Issn 0275-5947 English Journal Article ASFA 1: Biological Sciences & Living Resources; Ecology Abstracts; Water Resources AbstractsX,"Jowett, I.

Water depths and velocities were measured in each sampling lane. Fish were most abundant along the river margins less than 0.25 m deep, both during the flood and in normal flows. Two days after the flood, these shallow areas, that had been occupied by fish during the flood, were dry again. This suggests that the edge-dwelling fish species in these rivers respond quickly to flow changes, moving with the river margins to minimise any change in depth. Response to changes in velocity were less apparent and the water velocity in the areas occupied by edge-dwelling fish during the food was sub-optimal in terms of normal habitat preference. The response of fish to flow and habitat change and the use of sub-optimal habitat for short periods of time highlights the difficulty of interpreting a time series of weighted usable area.1994 Issn 0028-8330 English Journal Article ASFA 1: Biological Sciences & Living Resources; Ecology Abstracts; Water Resources Abstracts,&Jude, D.

Attention is directed to the status of the survival of each species. Wherever possible, suggestions have been made of immediate protection of individual species. However, the actual, modern conservation has to be based on the protection of species communities and their environments. It is hoped this publication will stimulate the effort to overcome the existing gaps in the knowledge of the fish communities in rivers, and particularly of their dynamics in artificially modified environments. Past experience has proved that exaggerated attention to a few "useful" species influences the remaining fish community negatively. A separation of the "utilitarian" and "conservation" usages of the aquatic environment and its fish fauna is thus called for.THE FRESHWATER FISHES OF EUROPE., vol. 9, AULA-VERLAG, WIESBADEN (FRG) , 1987, 343 pp Incl. 140 ref.

The sites, which included all stream orders from I-VI, were divided into three categories: natural, modified and moderately polluted. In lower order streams, river channel modifications had a negative influence on fish species diversity and the population density and the standing crop of lithophilous species. In modified, higher order streams these indices of fish population dynamics increased probably because of an increase in fish refuges along the banks, where the latter were reinforced with large stones and tree branches.

Seven designs previously studied in 1986 were further examined (designs 1-7) and 11 more designs (numbered 8-18) were tested. The vertical slope fishway models were installed in a plexiglass flume having nine pools, at a scale of 1:8. Slopes of 0.05, 0.10, and 0.15 were used, and the flow rate was measured by means of a magnetic flow meter installed in the supply line. Designs 8-13 were tested mainly to determine how sensitive the standard length of ten times the width of the slot and the standard width of eight times the width of the slot are for satisfactory performance of the vertical slot fishway. Designs 14-18 were simplified versions of the standard design (design 1). For all 18 designs, the dimensionless discharge was found to vary linearly with the relative depth of flow, with the straight line passing approximately through the origin on most of the designs. The results showed that a width of eight times the width of the slot and a length of ten times the width of the slot for the pools are satisfactory, and minor variations can be made to these dimensions without affecting their satisfactory performance. The performance rating curves were essentially the same for one group including designs 3, 5, 6, and 7 and for another group including designs 1,2, 14, 16, 17, and 18. Design 6 in the first group and designs 16 and 18 in the second group are recommended for practical use because of their ease of construction.Canadian Journal of Civil Engineering CJCEB8, Vol. 19, No. 3, p 402-414, June 1992. 5 fig, 2 tab, 7 ref.

Velocity measurements were made with a 10-mm impeller minicurrent meter, and velocity profiles were calculated. The velocity profiles obtained in the field studies have confirmed the measurements made in the laboratory on scale models and have enhanced the general picture, particularly for the vertical slot fishways. A routine inspection and maintenance program would be helpful in ensuring that the fishways in Alberta operate at maximum efficiency. The design of the fish entrance is very important in determining the success of a fishway. Where the flow at the water outlet is not strong enough, the use of auxiliary attraction water should be considered. The standard Denil fishway provides a strong flow at the water outlet and therefore effectively supplies attraction water. One exception to this is a high tailwater condition, where the velocity of flow can be significantly reduced. All fishways should be equipped with trash racks at the water inlet to prevent fishway blockage by debris. The field measurements on standard Denil fishways in Alberta were found to agree reasonably well with the laboratory results. The field measurements on vertical slot fishways, in addition to supporting laboratory measurements, have also provided more information on the circulation in the pools and should be useful in building a better understanding of the hydraulics of the vertical slot fishway.Canadian Journal of Civil Engineering CJCEB8, Vol. 19, No. 4, p 627-638, August 1992. 18 fig, 10 ref.

To test this hypothesis, sample sites of similar mussel density and diversity were chosen from Pools 15, 16, 18, 19, 26 of the Mississippi River, and one site from the Illinois River. Electrophoretic analysis indicated gene flow among the mapleleaf populations tended to be higher within pools and lower between pools separated by lock and dam systems. Catfish populations exhibited relatively low levels of genetic variability, particularly in Pool 19, where episodes of pollutant stress may have been a factor. P. olivaris appears to have a direct effect on the genetic structure of Q. quadrula. Analyses of systematic relationships among populations of both species showed some parallelism of population structure between the two species. A previous study on Amblena plicata did not produce a similarity in that species population structure with P. olivaris. Therefore, the data suggest that the flathead catfish is the predominant host fish with mapleleaf mussel's glochidia.

The study was started in the fall of 1982 to evaluate the fishing pressure and catch of anadromous fish. Visual counts were made at each fish ladder in spring and fall on a random around-the-clock basis to measure the number of salmonids moving upstream. Spring floods appeared to aid steelhead migration but hindered fishing. Returns of stocked salmonids to the Grand River fishery were roughly estimated by comparing average number stocked to average number harvested. Returns were about 2.8% for coho, 3.4% for chinook, and 2.2% for steelhead.@,(!Smiley, P. C., Jr. Parsons, G.

We studied the effects of five photoperiods, designated 24L:0D (24 h light:0 h dark), 16L:8D, 12L:12D, 8L:16D, 0L:24D, and three temperatures (5, 15, and 25 oC) on the swimming performance of white crappie Pomoxis annularis (5-11 cm in standard length) in a swim tunnel with propeller-driven flow. Two-factor analysis of variance (alpha = 0.05) indicated that both photoperiod and temperature significantly affected fish swimming performance but the interaction of photoperiod and temperature did not. At all temperatures, the 8L:16D photoperiod resulted in the highest mean swimming speeds. In addition, the temperature effect was consistent at all photoperiods. The mean swimming speed at 5 oC was significantly slower than at 15 oC or 25 oC; however there was no significant difference between swimming speeds at 15 oC and 25 oC. Our documentation of a photoperiod effect on fish provide further confirmation of the importance of this environmental variable on swimming performance. j  k                    May 1997 Issn 0002-8487 English Journal Article ASFA 1: Biological Sciences & Living Resources; Ecology Abstracts; Animal Behavior Abstracts ~Kynard, B.

Groups of 5-29 fish were exposed to combinations of two bypass exits (wide-shallow and vertical-slot sharp-crested weirs) and two louver arrays (7.6- and 15.2-cm slat spacing) oriented 20 degree to water flow direction. Underwater video observations showed fish responded to louvers as a physical barrier during the day, when they stayed 30-55 cm (1.3 cm/5 klx) away from and oriented parallel to louvers, and as a behavioral barrier at night, when they moved closer to louvers and oriented into the current. Both louver arrays guided fish effectively, (i.e., prevented fish from passing through the slats) 100% for narrow spacing and 97% for wide spacing. Adults avoided moving closer than 0.5 m to either exit type; instead, fish remained 0.8-1.4 bodylengths upstream, depending on light intensity (farther upstream during daytime, similar to behavior at louvers). At exits, water velocity increased from 0.4 m/s to 0.8 m/s or more in a distance of 0.9 m (rate of velocity increase, 0.44 m/s per meter). This rapid velocity increase elicited an avoidance response by fish that resulted in few fish (5%) passing. Our results provide behavioral explanations for the efficient guidance of adult American shad by louvers and for the fishes' avoidance of the exit at the Holyoke Dam. From this, we provide suggestions on how to prevent fish avoidance of exits.0 " 3 Aug 1997 Issn 0275-5947 English Journal Article ASFA 1: Biological Sciences & Living Resources; ASFA 3: Aquatic Pollution & Environmental Quality; Oceanic Abstracts; Water Resources Abstracts; Ecology Abstracts; Animal Behavior AbstractsiBBanneheka, S.

The technique includes refinements and additions to one developed by the International Pacific Salmon Fisheries Commission to estimate sockeye Oncorhynchus nerka and pink salmon Oncorhynchus gorbuscha migrations in the Fraser River. The estimator is independent of the actual shape of the effective acoustic beam and the distribution of target strengths when the same hydroacoustic equipment and settings are used for both types of soundings. Thus, the method shares with the duration-in-beam method the advantages that equipment calibration requirements are minimal and that estimates remain valid when fish sizes vary over a wide range. We also provide formulae for the variance of the abundance estimate and illustrate the methods with example calculations of daily fish passage in the Fraser River at Mission, British Columbia. A correction procedure is proposed to compensate for bias arising from violation of the assumption that fish speed is negligible relative to boat speed.  ) : P 1995 Issn 0706-652x English Journal Article Ecology Abstracts; Animal Behavior Abstracts; ASFA 1: Biological Sciences & Living Resources; Oceanic Abstracts; Water Resources Abstracts xLucas, M.

Barbel exhibited substantial movements, ranging from 2 to nearly 20 km. Four fish are known to have moved between the Nidd and the Ouse, demonstrating that at least a part of the barbel population utilize the Nidd and Ouse at different times of the year. Range of upstream movement was restricted by the presence and nature of several weirs, including Skip Bridge flow-gauging weir. Low levels of spawning downstream of Skip Bridge weir appear to have been due to a lack of suitable spawning habitat. Movements followed a seasonal pattern, with males and females migrating upstream in spring to spawn on gravel beds. Females moved downstream more quickly than males over the summer months. Both sexes moved downstream in autumn and winter. Day length and water temperature were the best predictors in relation to distance moved up the River Nidd. Descriptive models, relating movement to water temperature and day length, are provided. For both sexes, localized activity varied greatly on both diel and seasonal scales, and was mainly associated with foraging. During summer there was typically a bimodal pattern of diel activity with peaks usually in early morning and late evening. In winter, mean daily activity was less than 20% of peak summer levels and fish were relatively dormant. In winter, diel activity patterns exhibited a single peak towards dusk. Mean daily activity levels for each month were linearly correlated with mean monthly water temperatures, even during the months where movement to and on the spawning sites occurred. The importance of natural migrations and seasonal activity patterns for barbel, and likewise many other riverine cyprinids, has probably been underestimated for a wide variety of river systems. As major components of riverine fish communities, the importance of seasonal movements of mobile cyprinid species should be considered when constructing weirs and other obstructions. Greater consideration should be given to ways of mitigating effects of existing barriers to movement of non-salmonid species.

Most upstream movement occurred during May. Fifteen of the 23 fish tracked attempted to pass the weir, and of these six were successful. Barbel tended to approach the weir around dusk and dawn, reflecting observed patterns of localized activity, or at night, but crossed the weir only at night. Those fish which crossed the weir moved substantial distances upstream to spawn, while those that were unsuccessful moved downstream. The weir delayed the net upstream progress of all adult barbel. Successful traversal was not closely related to flow or water temperature conditions. The study emphasizes the impact of relatively minor obstructions on the natural migrations of barbel.

Although total mussel abundance varied significantly as a function of sediment and current (P <= 0.05), abundance could be predicted in only 44% of sites by discriminant analysis models. Accurate prediction of abundance for most species also was poor. Species showed little discrimination in choosing main channel habitats, but could be broadly classified into species preferring fine to medium-fine sands (e.g., Truncilla truncata and Potamilus alatus) or coarser sands (e.g., Lampsilis cardium and Truncilla donaciformis). The endangered Lampsilis higginsi was found in a broad range of habitats similar to those occupied by many of the more common species, suggesting factors other than loss of adult habitat for the rarity of this species.          ! 3 `Z1990 Issn 0887-3593 English Journal Article ASFA 1: Biological Sciences & Living ResourcesDf Klinge, M. 1994d]Fish migration via the shipping lock at the Hagestein barrage: Results of an indicative study Van de Kraats, J.

Because of intensive shipping these works are always combined with big shipping locks. Until recently no data were available concerning fish migration via this locks. This was studied in the river Lek at the Hagestein barrage. Due to the short length of the study period and few recaptured salmonids (salmon, sea trout, rainbow trout) no conclusive evidence about the effects of the shipping lock on salmonid migration was obtained. However, the results do suggest that the Hagestein barrage complex forms a serious barrier for upstream migration of salmonids. Several other fish species on other hand were observed to migrate through the lock. Therefore, depending on target species and management goals, the presence of shipping locks should be taken into account when considering improving fish migration possibilities.Conference International Conference on Rehabilitation of the River Rhine, Arnhem (Netherlands), 15-19 Mar 1993 REHABILITATION OF THE RIVER RHINE., ELSEVIER SCIENCE, TARRYTOWN, NY 10591-5153 (USA), 1994, pp. 357-361, Water Science and Technology [WATER SCI.

To test this hypothesis, the critical swimming speeds (Ucrit) of fish laboratory acclimated to 5, 10, 15, or 19 oC, and seasonally consistent or 12:12 light-dark photoperiods, were compared to that of field-acclimatized bass. In early winter the Ucrit of largemouth bass laboratory acclimated to 5 oC and a 12:12 light-dark photoperiod was significantly reduced relative to that of fish field acclimatized to 5 oC but was not significantly different when compared to that of fish acclimated to 5 oC and a seasonally consistent 9:15 light-dark photoperiod. In early summer the Ucrit of largemouth bass laboratory acclimated to 10 oC and a 12:12 light-dark photoperiod was significantly reduced relative to the Ucrit of fish either acclimated to 10 oC and a seasonally consistent 15:9 light-dark photoperiod or field acclimatized to 10 oC.f q   @ F  G  @    q  r     @ K  L  @       |u1991 Issn 0045-8511 English Journal Article Animal Behavior Abstracts; ASFA 1: Biological Sciences & Living Resourcesn H  Miller, A.

Twenty-three species and 4,768 freshwater mussels were obtained in 287 qualitative collections. The bivalve fauna was dominated by two thick-shelled species, Amblema plicata (39.43 percent) and Fusconaia ebena (39.41 percent). Six species comprised 1 to 10% of the collection, and 15 species made up less than 1% of the collection. No Federally listed endangered species were found. Species diversity was moderate, and evenness was low Unionid density at six sites in the area to be dredged ranged from 9.2 to 128.0 individuals per square meter. Corbicula fluminea density ranged from 6.0 to 26.4 individuals per square meter, which was considerably less than values reported in this river reach in 1969. The total commercial value of four species (A. plicata, Megalonaias nervosa, F. ebena, and Quadrula quadrula) within the area the will be dredged was estimated at $101,707. Total density of snails ranged from 8.0 to 86.8 individuals per square meter; the fauna was dominated by Pleurocera canaliculatum , with lesser numbers of Lithasia armigera and L. verrucosa . Impacts due to construction and operation of the second lock can be partially offset by creating submerged habitats with dredged materials along an eroding bank downriver of the lock and dam.   ) 8   T }   > V p    TECH.

The presence of juveniles and adults in the collections makes it appear that grass carp are reproducing in the Illinois River, and their larvae are finding suitable nursery areas in backwaters.

Seventeen paddlefish were tracked in two pools (12 and 13) of the Upper Mississippi River during the summer of 1980 and spring and summer of 1981. Interpool movement occurred during spring high water periods when dam gates were lifted to create a free-flowing river. Habitat use varied by season. Selection was greatest for tailwater and channel habitats, although strong association with one backwater slough was evident. Even when backwaters are not directly utilized, invertebrate drift from these areas may be important. Paddlefish often congregated near man-made structures that created eddies and reduced current velocities.Transactions of the American Fisheries Society Vol. 113, No. 2, p 123-131, March, 1984. 3 Fig, 4 Tab, 31 Ref.

The importance of large river floodplain ecosystems in providing diverse and rich habitats for aquatic and terrestrial species is discussed. Anthropogenic impacts on large floodplain rivers are reported to be extensive and to have profound consequences in system function. Most salient are issues of connectivity. The goals of ecosystem management are defined to be the maintenance or recovery of biological integrity of the ecosystem. Biological integrity is argued to comprise not just the full range of species present prior to anthropogenic impacts, but more importantly, all of the variability and processes that comprise the system. To define a reference point from which to manage from, the author suggests that the predisturbed ecosystem should be the appropriate benchmark. Restoration of the floodplain, the annual flood pulse, and the long-term variability in the system are forwarded as management policies to restore large river floodplain ecosystems.$Stamhuis, E. J.

Successive video images, recorded perpendicular to a light sheet parallel to the main stream, were digitized and processed to map the flow velocity in two-dimensional planes. In particle tracking velocimetry (PTV), displacements of single particles in two subsequent images were determined semi-automatically, resulting in flow diagrams consisting of non-uniformly distributed velocity vectors. Application of grid-cell averaging resulted in flow field diagrams with uniform vector distribution. In sub-image correlation PIV (SCPIV), repetitive convolution filtering of small sub-areas of two subsequent images resulted in automatic determination of cross-correlation peaks, yielding flow field diagrams with regularly spaced velocity vectors. In both PTV and SCPIV, missing values, caused by incomplete particle displacement information in some areas of the images or due to rejection of some erroneous vectors by the vector validation procedure, were interpolated using a two-dimensional spline interpolation technique. The resultant vector flow fields were used to study the spatial distribution of velocity, spatial acceleration, vorticity, strain and shear. These flow fields could also be used to test for flow in the third dimension by studying the divergence, and to detect the presence and location of vortices. The results offer detailed quantitative descriptions of the flow morphology and can be used to assess dissipated energy. The versatile character of the technique makes it applicable to a wide range of fluid mechanical subjects within biological research. So far it has been successfully applied to map the flow around swimming copepods, fish larvae and juvenile fish and the ventilation current of a tube-living shrimp.1995 Issn 0022-0949 English Journal Article ASFA 1: Biological Sciences & Living Resources; ASFA 2: Ocean Technology Policy & Non-Living Resources.(Stanford, J.

Stemming from these efforts, four relatively large fish passes were built between 1984 and 1989 on the Garonne and Dordogne rivers in south-west France. Two are pool-type fish passes (one with a double vertical slot at Bergerac on the Dordogne River, and the other with a single vertical slot at Le Bazacle on the Garonne River); the other two are fish elevators (Golfech on the Garonne River and Tuilieres on the Dordogne River). This chapter describes the characteristics and operating constraints of each installation. Since construction, operations have been monitored on a more or less (dependent on site) constant basis using a semi-automated video counting device which provides precise data on the quantity and timing of fish passage. The four installations have enabled passage of some 30 fish species, including migratory diadromous populations of Atlantic salmon Salmo salar, sea-run brown trout Salmo trutta, allice shad Alosa alosa, European eel Anguilla anguilla, sea lamprey Petromyzon marinus, and a number of so-called 'sedentary' species such as roach Rutilus rutilus, bream Abramis brama, and barbel Barbus barbus for which very clear migration rhythms have been nonetheless observed. Passage of allice shad, which has often been difficult to achieve over traditional fish passes, has been found satisfactory in both the pool and elevator installations, with annual passage of several tens of thousands of individuals (80 000 to 86 000 shad at the Tuilieres and Golfech fish elevators in 1995). The relative effectiveness of each type of pass is discussed in relation to the various migratory species. Finally, the main results concerning the seasonal and daily migratory rhythms of various diadromous and resident species are presented..    & 4 ?

Young-of-the-year fish were caught in 1992 and 1994, which suggests that the species is able to reproduce in the Mississippi River and may become established. Because H. nobilis is a low level filter feeder, its presence may affect other filter feeding fishes such as the paddlefish Polyodon spathula, bigmouth buffalo Ictiobus cyrinellus, and gizzard shad Dorosoma cepedianum. Further research is needed to confirm that the species is established and what its biological impact will be.  4 N    + > Q d w JD, Aug 1997, 10 pp. Report: LTRMP97-R014.

At present the ichthyofauna totals 153 species belonging to 19 families, including 13 species which have been introduced. Because Minnesota was covered by glacial ice until at least late Wisconsinan time, species that migrated into the state from the periglacial region could have been derived from three refugia: unglaciated Alaska, the Atlantic refugium, and the lower Mississippi River refugium. The routes followed in their dispersal were dependent upon the drainage connections that existed during late Pleistocene and early Holocene time. Fish migration paths were largely determined by the formation of large glacial lakes such as Lake Agassiz, Lake Koochiching, Lake Duluth, and Lake Ontonagon. Advances and retreats of various glacial lobes controlled the size and drainage directions of the glacial lakes, allowing migration of fishes from different refugia at different times. The geologic evidence for Holocene drainage is more conjectural, and the present distribution of species can be used to infer changes in drainage during this period of time.Journal of the Minnesota Academy of Science JMNAAC Vol. 55, No. 1, p 32-37, Fall 1989. 1 tab, 34 ref.

One factor affecting the magnitude of the lift force is the area of the propulsor. Resistance to cruising and sprints is mainly due to drag, but inertia is important during maneuvers when animals accelerate or turn. The inertia of the body and entrained water, which is proportional to body volume, resists acceleration. Because a thrust that is proportional to surface area is used to maneuver a resistance that is proportional to volume, acceleration performance and maneuverability are expected to decline with increasing size. This trend is ameliorated to some extent by the high swimming speeds attainable by warm-bodied vertebrates and the reduced resistance to acceleration characteristic of the skeletons of dolphins and ichthyosaurs. Maneuvers are essential for capture of elusive prey and avoidance of predators. As they increase in size, aquatic vertebrates use various means to ensure that their prey are less maneuverable than they.F?Conference From Environment to Fish to Fisheries: A Tribute to F.E.J.

The body was similarly flexed by both species during fast-starts and steady swimming. Therefore, the heavy integument of the gar did not affect flexibility during swimming. Distance traveled in a given elapsed time during fast-starts was lower for the gar, which averaged 65% of the work done by the musky. On the basis of differences in muscle mass, gars would be expected to perform 72% of the work of muskies during a fast-start. The heavier integument of the gar was estimated to contribute about 90% to the reduced fast-start performance. In steady swimming, mechanical power requirements at a given speed were similar for both gar and musky. Therefore, steady swimming costs do not appear to be affected by armor. The critical swimming speed of gars was 1.9 body lengths/s compared with 3.4 body lengths/s for muskies, but the difference could not be attributed to differences in armoring. The slip speed at which gars first began to swim was 1.21 body lengths/s compared with 0.75 body lengths/s for muskies. Higher station-holding performance is probably not important to modern gars and esocids, but may have been advantageous during the early radiation of fishes.

As a result, physiological studies pertinent to swimming are legion, necessitating discussion of only a few selected topics in this chapter, which focuses on the nature and properties of the propulsion system. This is comprised of a propulsor that transfers momentum from the fish to the water, thereby generating thrust, and the muscles that drive those propulsors. Neural control systems are not discussed. Swimming energetics are discussed because driving the propulsors is a major expense affecting design criteria for many other physiological systems as well as the impact of fish on their ecological resource base. In addition, the amount of energy available for swimming is often constrained by environmental factors. Scale effects are omitted.THE PHYSIOLOGY OF FISHES., CRC PRESS, BOCA RATON, FL (USA), 1993, pp. 47-74 English Book Monograph ASFA 1: Biological Sciences & Living Resourcess2+Webb, P. W. LaLiberte, G.

Obstacles were vertical and horizontal rectangular slits of different widths, for which width was defined as the minimum dimension of a slit irrespective of slit orientation. Performance was measured as the smallest slit width traversed. Three species with different body and fin patterns were induced to swim through slits. Species tested were: goldfish Carassius auratus with a fusiform body, anterio-ventral pectoral fins and posterio-ventral pelvic fins; silver dollars Metynnis hypsauchen with the same fin configurations but a gibbose body; angelfish Pterophyllum scalare with a gibbose body and anterio-lateral pectoral fins. Minimum slit widths negotiated were normalized with the length of various body dimensions: total length, maximum width, span at the pectoral fins, and volume super(1/3) (numerically equal to mass super(1 /3)). Goldfish had the poorest performance, requiring the largest slit widths relative to these body dimensions. No consistent patterns in performance were found for silver dollars vs. angelfish. There were no differences among species in the ratio of minimum vertical slit width negotiated to that for horizontal slits, indicating fish were equally able to control posture while swimming on their sides. There were also no consistent patterns in the times taken to transit slits. Although the deep-bodied fish were able to maneuver through smaller slits, the most striking result is the similarity of minimum slit widths traversed in spite of the large variation in body form. Body form and fin plan may be more important for maneuvering and posture control during sub-maximum routine activities.e`Z1996 Issn 0378-1909 English Journal Article ASFA 1: Biological Sciences & Living Resources4.(Jones, D.R.

In five species the relation between fatigue time and swimming speed was investigated. Critical velocity data from 10 species were analyzed by solving the regression equation V = KLe (where V = critical velocity in cm/s, L = fork length, K = constant, e = exponent). Neither acclimation to different temperatures nor temperature shock over a range of +/- 7 oC from acclimation temperature had a significant impact on critical velocity. Intraspecific variation was found to be unrelated to maturity, sex, or condition factor. From a graphical presentation of body length vs. maximum flow rate allowable in a 100 m culvert, it appears that culvert flow rates should be kept below 30-40 cm/s to allow successful passage of the majority of mature individuals of migratory species.    o  p  Jonsson, N. 1991PJInfluence of water flow, temperature and light on fish migration in rivers,%Nordic Journal of Freshwater Research66 20-35water flow; water temperature; light; Pisces; migration; rheotropism; river outflow; temperature effects; light effects freshwater fish; rivers Freshwater Q1 01422 Environmental effects; D 04668 Fish; Y 25655 FishoWater flow, water temperature and light are environmental variables that influence when fish migrate and the intensity of the migration itself. These variables apply both to up- and downstream migration, but their effects may among rivers and species. During the ontogeny, migratory fish in different life history stages are transported downstream by the water flow. Changes in water flow may influence when the fish migrate. To be carried downstream, the fish must position themselves within the water column and actively swim of out sloughs and backwaters. High water discharge may stimulate the river ascent. Water temperature is an important factor initiating up- and downstream migrations of several fish species. In particular, this may be the case in rivers where freshets do not regularly occur at the time when the environmental shift is favourable. Migrations of juveniles and adults are mainly nocturnal, but sometimes diurnal. When the migration occurs during dark hours this is expected to be an adaptation to avoid visual predators.1991 Issn 1100-4096 English Journal Article ASFA 1: Biological Sciences & Living Resources; Ecology Abstracts; Animal Behavior Abstractsd$McIninch, S.

The elevator has a pair of parallel tubular passageways having one set of identical corresponding transverse dimensions and a second set of different corresponding dimensions. Endless chains are arranged in parallel reaches with one reach extending along the mid-point of the adjacent side of one of the passageways and the other reach of the chain extending midway along the adjacent side of the other passageway. Corresponding reaches of the chains have partitions secured between them. The partitions are mounted so as to be slightly oscillatable and held in tight sliding engagement with the associated passageways. The elevator works somewhat in the manner of an undershot waterwheel with means provided to admit fish to be elevated to the higher level or lowered to the lower level into the compartments between adjacent partitions.U.s. patent no. 3,783,623, 4 p, 9 fig, 7 ref; official gazette of the united states patent office, vol 918, no 2, p 577, january 8, 1974.

This gradient should elicit a series of responses within the constituent populations resulting in a continuum of biotic adjustments and consistent patterns of loading, transport, utilization, and storage of organic matter along the length of a river. Based on the energy equilibrium theory of fluvial geomorphologists, we hypothesize that the structural and functional characteristics of stream communities are adapted to conform to the most probable position of mean state of the physical system. We reason that producer and consumer communities characteristic of a given river reach become established in harmony with the dynamic physical conditions of the channel. In natural stream systems, biological communities can be characterized as forming a temporal continuum of synchronized species replacements. This continuous replacement functions to distribute the utilization of energy inputs over time. Thus, the biological system moves towards a balance between a tendency for efficient use of energy inputs through resource partitioning (food, substrate, etc.) and an opposing tendency for a uniform rate of energy processing through the year. We theorize that biological communities developed in natural streams assume processing strategies involving minimum loss of energy. Downstream communities are fashioned to capitalize on upstream processing inefficiencies. Both the upstream inefficiency (leakage) and the downstream adjustments seem predictable. We propose that this River Continuum Concept provides a framework for integrating predictible and observable biological features of lotic systems. Implications of the concept in the areas of structure, function, and stability of riverine ecosystems are discussed.."Vaughn, C. C. Taylor, C.

Q5 01521 Mechanical and natural changes; SW 4070 Ecological impact of water development; D 04705 Conservation .(One major factor leading to the imperilment of freshwater mussels (Bivalvia, Unionidae) has been the large-scale impoundment of rivers. We examined the distribution and abundance of mussels at 37 sites along a 240-km length of the Little River in southeastern Oklahoma, U.S.A., which is affected by both mainstem and tributary reservoirs. We observed a mussel extinction gradient downstream from impoundments in this river: with increasing distance from the mainstem reservoir there was a gradual, linear increase in mussel species richness and abundance. Mussel species distributions were significantly nested, with only sites furthest from the impoundment containing relatively rare species. Below the confluence with the inflow from the second reservoir these same trends were apparent but much weaker, and overall mussel abundance was greatly reduced. Our results suggest that considerable stream lengths are necessary to overcome the effects of impoundment on mussel populations, and such information should be considered in conservation and management plans.Aug 1999 Issn 0888-8892 English Journal Article ASFA 3: Aquatic Pollution & Environmental Quality; Water Resources Abstracts; Ecology Abstracts2,Vehanen, T.

Both lakes are regulated for hydroelectric purposes. In both rivers, two sonar stations with stationary up- and down-looking transducers were used to collect data for one year. The fish migration rate in the River Oulujoki was greater than in the River Paatsjoki. In the River Oulujoki, the fish migrated mainly downstream and in the River Paatsjoki both down- and upstream. In the River Paatsjoki, larger fish showed active migration in the spring and autumn, whereas in the River Oulujoki the increase in the migration occurred simultaneously in all size groups. The different species composition and the different nature of the lakes, together with the different regulation practices, were considered to be responsible for the varying migration patterns. It was concluded that no barriers to fish migration should be built on these rivers.Apr 1998 Issn 0969-997x English Journal Article Water Resources Abstracts; Ecology Abstracts; ASFA 1: Biological Sciences & Living ResourcesVideler, J.

Most swimming bouts consist of a single tail flick and a coasting phase, during which the fish keeps its body straight. When visualising the flow in a horizontal section through the wake, the effects of the flow regime become apparent in the structure of the wake. In a two-dimensional, medio-frontal view of the flow, larvae and adults shed two vortices at the tail during the burst phase. These vortices resemble a cross section through a large-core vortex ring: two vortex cores packed close together with the central flow directed away from the fish. This flow pattern can be observed in larvae (body length approximately 4 mm) at Reynolds numbers below 100 as well as in adult fish (body length approximately 35 mm) at Reynolds numbers above 1000. Larval vortices differ from those of adult zebra danios mainly in their relatively wider vortex cores (higher ratio of core radius to ring radius) and their lower vortex circulation. Both effects result from the increased importance of viscosity on larval flows. During the coasting phase, larval and adult flows again differ because of the changing importance of viscosity. The high viscosity of the water causes large vortical flows adjacent to the larva's body. These regions of high vorticity represent the huge body of water dragged along by the larva, and they cause the larva to stop almost immediately after thrust generation ceases. No such areas of high vorticity are visible adjacent to adult zebra danios performing a comparable swimming manoeuvre. The rapid decrease in vortex circulation and the severe reduction in the coasting distance due to viscous drag contribute to the high cost that larvae - unlike adult fish - face when using a burst-and-coast swimming style.1   d^Jan 2000 Issn 0022-0949 English Journal Article ASFA 1: Biological Sciences & Living Resourcess RrP  Grady, J.M.

Although peripheral range has dwindled, paddlefish still occur over most of their historic range and are still found in 22 states. Populations are currently increasing in 3 states, stable in 14, declining in 2, unknown in 3, and extirpated in 4. Sport harvests presently occur in 14 states, however two states with traditionally important sport fisheries report decreased recruitment into the population and are planning more restrictive regulations. Commercial fisheries are reported in only six states. During the past 10 years, five states have removed paddlefish from their commercial list primarily because of declines in adult stocks due to overfishing or illegal fishing. Ten states are currently stocking paddlefish to supplement existing populations or to recover paddlefish populations in the periphery of its native range.n  , lf1997 Issn 0378-1909 English Journal Article; Conference ASFA 1: Biological Sciences & Living ResourcesGrande, R.

The power plant, with a 6 m-high dam, is located on the upper portion of the waterhall. The fishway consists of a pool-and-weir pass in the lower part of the waterfall, linked to a pressure-chamber fishway (a kind of fish lock) in the dam. Between the dam and the powerhouse downstream, there is a 2 km-long residual flow stretch. Fishways were also built at three weirs within this residual flow stretch. The pressure-chamber fishway is new for Norway. Fish swim into a chamber at the base of the dam and when a sufficient number have entered, a diffuser closes and the pressure is increased to equal that found upstream of the dam. Another diffuser opens giving the fish access to a duct leading to the river above the waterfall. The system was constructed to take Atlantic salmon Salmo salar and sea-run brown trout S. trutta past the dam. Four years of trials have given positive results. This chapter describes the construction of this pressure-chamber fishway, how it works and our operating experience so far.Conference Fish Migration and Fish Bypass Channels Symp., Vienna (Austria), 24-27 Sep 1996 Fish Migration and Fish Bypasses, Fishing News Books, 1998, pp. 236-245 Price: pound sterling 65.

The revision of The Watercourse Act gave balanced priority to drainage of water and environmental quality, focusing on an ecologically more appropriate maintenance practice and giving special provisions for stream restoration activities. Different measures of single structure restoration have been used, the most common being replacement of weirs, dams or other obstacles by rapids, establishment of salmonid spawning grounds, and installation of new or improved fish ladders. The most common stream channel restoration method is integrated use of a number of single structure measures. Establishment of a two-stage channel and re-opening of small piped streams have also been used. Stream valley restoration includes restoration of old meanders or establishment of a new sinuous channel and involves the adjacent riparian areas. The changed stream maintenance practice involves a new strategy for dredging and cutting of weeds and bank vegetation in order to minimize the ecological damage caused by keeping a reasonable discharge capacity. In 1990, environmentally acceptable weed-cutting was performed in 37% of all municipal streams and the bank vegetation was left uncut in a third of the streams. Similarly, more than half of the county streams were maintained using hand scythes and in 74% of the streams the bank vegetation was left uncut. Quantitatively, stream restoration has contributed little to the general improvement of Danish streams compared with changed maintenance practice. Stream restoration projects create public interest in the environmental quality of streams, but major improvements in the physical properties of Danish streams depend on future maintenance practice. Due to major changes predicted in Danish agriculture many riparian areas and wetlands will reappear and the natural or semi-natural physical properties of streams will be re-established by natural processes or changed in maintenance practice. However, there will still be large areas with intensive agriculture, where environmental and agricultural interests must be balanced. The Danish experience has shown that this is possible.1993 Issn 1052-7613 English Journal Article Ecology Abstracts; Pollution Abstracts; ASFA 3: Aquatic Pollution & Environmental Quality; Water Resources Abstractsd]Jackson, G.

Data on the status and distribution of paddlefish populations in the Upper Mississippi River needed to respond to the petition data were scarce or lacking. Thus, a mail survey was conducted to assess the distribution and status of paddlefish populations in the upper river. During the summer of 1990, 705 questionnaires were mailed to fishery scientists and commercial fishermen from the five states bordering the Upper Mississippi. Thirty seven percent of the questionnaires (260 of 705) were completed and returned. A significant portion of the respondents (59%) indicated that they have caught paddlefish in the Upper Mississippi River. Of those, about half had caught paddlefish rarely, and one-third had commonly or frequently caught paddlefish. Most paddlefish were found in navigation Pools 8, 10, 13, and 19. Fishery classification status ranged from commercial to protected for the five states surveyed. The results of this survey suggest that paddlefish populations in the Upper Mississippi River still occupy much of their historic range. Moreover, many of the fishery biologists surveyed believed that paddlefish populations in the Upper mississippi River are stable and may be increasing. X i $Jennings, C. A. Wilson, D.

Design characteristics of UMR navigation dams allow both upstream and downstream fish passage. Upstream fish passage is dependent upon hydraulic conditions at the dam, fish behavior, and swimming performance. Physical hydraulic modeling of current patterns through UMR dam gates and analysis of swimming performance of several UMR fish species indicate that opportunity for upstream fish passage occurs at lock and dam 8 during most water years. Operation of hydropower units at UMR dams may decrease opportunity for upstream fish passage.Conference Ecological Society of America and American Society of Limnology and Oceanography Joint Annual Meeting, Minneapolis, MN (USA), 17-21 Jun 1985.

This constitutes 28% of the known fauna. The status of fishes and their habitats continues to decline, especially in the arid regions of western U.S.A. and northern Mexico. The Endangered Species Act is the most powerful tool currently available to protect rare fishes. While many fishes probably have been saved from extinction by this act, surprisingly few have improved enough to be removed from under its protection.

D. Warren, M. L., Jr. Cummings, K. S. Harris, J. L. Neves, R. J.  Fisheries 189 6-22The American Fisheries Society (AFS) herein provides a list of all native freshwater mussels (families Margaritiferidae and Unionidae) in the United States and Canada. This report also provides state and provincial distributions; a comprehensive review of the conservation status of all taxa; and references on biology, conservation, and distribution of freshwater mussels. The list includes 297 native freshwater mussels, of which 213 taxa (71.7%) are considered endangered, threatened, or of special concern. Twenty-one taxa (7.1%) are listed as endangered but possibly extinct, 77 (20.6%) as endangered but extant, 43 (14.5%) as threatened, 72 (24.2%) as of special concern, 14 (4.7%) as undetermined, and only 70 (23.6%) as currently stable. The primary reasons for the decline of freshwater mussels are habitat destruction from dams, channel modification, siltation, and the introduction of nonindigenous mollusks. The high numbers of imperiled freshwater mussels in the United States and Canada, which harbor the most diverse fauna in the world, portend a trajectory toward an extinction crisis that, if unchecked, will severely impoverish one of our richest components of aquatic biodiversity. 1993<5freshwater molluscs; rare species; USA; Canada; geographical distribution; population number; Margaritiferidae; Unionidae; species diversity; conservation conservation status Freshwater Q1 01263 Taxonomy and morphology; Q5 01523 Conservation, wildlife management and recreation; D 04705 Conservation; Molluscs 1993 Issn 0363-2415 English Journal Article ASFA 1: Biological Sciences & Living Resources; ASFA 3: Aquatic Pollution & Environmental Quality; Ecology Abstracts0*Willson, M.

In addition, we suggest that the presence of a seasonally abundant food resource has helped to shape the evolution of aquatic and terrestrial consumers and that predators have probably exerted reciprocal evolutionary pressures on their prey, potentially influencing the life history and morphology of these fishes. Finally, we suggest that anadromous and inshore-spawning fishes constitute such an important prey base for terrestrial wildlife that conventional ecological and management dogmas need to be revised. Interactions between anadromous fishes and wildlife have been recognized as having some general ecological importance, but only recently have the ramifications of these interactions and their potential magnitude begun to be explored. Because many of the nuts and bolts of the ecological links still need to be described and quantified, we concentrate on sketching an outline of the interactions, documenting the effects where possible but also noting effects that seem probable, subject to future research.syJun 1998 Issn 0006-3568 English Journal Article; Review Ecology Abstracts; ASFA 1: Biological Sciences & Living Resourcesr$Winemiller, K.

Data were gathered for 216 North American fish species (57 families) to explore relationships among variables and to ordinate species. Multivariate tests, performed on freshwater, marine, and combined data matrices, repeatedly identified a gradient associating later-maturing fishes with higher fecundity, small eggs, and few bouts of reproduction during a short spawning season and the opposite suite of traits with small fishes. A second strong gradient indicated positive associations between parental care, egg size, and extended breeding seasons. Phylogeny affected each variable, and some higher taxonomic groupings were associated with particular life-history strategies.tm1992 Issn 0706-652x English Journal Article ASFA 1: Biological Sciences & Living Resources; Oceanic AbstractsH`.'Allendorf, F.

Despite harvest restrictions, lake sturgeon are still considered uncommon or rare in the Upper Mississippi River and are listed as endangered or a species of concern by four of five states bordering the Upper Mississippi River. Recovery of lake sturgeon populations in the Upper Mississippi River may be hindered due to system modifications, including the construction of low-head dams in the 1930's to accommodate commercial navigation. Moreover, recent proposals to further modify the Upper Mississippi River to accommodate increased commercial navigation has raised concern for remaining lake sturgeon populations. We are conducting a biotelemetry study to identify and describe inportant seasonal habitats of lake sturgeon in the Upper Mississippi River and to determine the effects of commercial navigation on lake sturgeon movements and habitat use. We tagged 23 lake sturgeon in the Upper Mississippi River with radio and ultrasonic transmitters during summer and fall, 1997. Twelve fish were tagged in the East Channel in Navigation Pool 10 near Prairie du Chien, WI and 11 fish were tagged in Polander Lake, an off-channel area in Navigation Pool 5A near Winona, MN. We attempted to obtain weekly locations and habitat use data on all fish, recording a total of 376 locations. Many lake sturgeon have moved considerable distances in 1997. Five fish tagged in Pool 10 moved up the Wisconsin River about 120 km to Prairie du Sac, five fish remained in Pool 10, and one fish moved 40 km upstream into Pool 9. One tagged lake sturgeon was harvested in the Wisconsin River by an angler in early September. Six fish tagged in Pool 5A remained in that pool and five fish moved up to 62 km to downstream pools. Preliminary analyses of data indicated that habitat use by lake sturgeon was similar between summer and fall. For fish tagged in Pool 10, 97% of the locations in the Mississippi River occurred in channel habitats, and 3 percent in off-channel habitats. In contrast, 57% of the locations of fish tagged in Pool 5A occurred in off-channel habitats. Mean depth and current velocity at fish locations in the Upper Mississippi River were 5.0 m and 22 cm/s, respectively. About 60% of fish locations occurred over sand, and 25% occurred over silt. We plan to continue tracking these tagged lake sturgeon until November 1998. # 7   F@Hove, M.C. Engelking, R.A. Long, E.M. Peteler, M.E.

Juvenile Ligumia recta were collected from only two (largemouth bass and walleye) of thirteen fish species tested. Suitable fish hosts identified for C. tuberculata and Lasmigona costata were previously unknown.

Management of rare unionids frequently demands knowledge of their fish host(s). Studies were conducted in 1994 to determine suitable fish hosts of the following unionids: purple wartyback Cyclonaias tuberculata, creek heelsplitter Lasmigona compressa, fluted-shell L. costata, black sandshell Ligumia recta, cylindrical papershell Anodontoides ferussacianus, and squawfoot Strophitus undulatus. Suitable fish hosts were determined by artificially exposing fish to mussel glochidia and determining if they facilitated glochidia metamorphosis to the juvenile stage. Six fish species were infested with C. tuberculata glochidia, but only the yellow bullhead Ameiurus natalis served as a suitable host. Four of ten fish species tested were found to be suitable hosts for Lasmigona compressa: spotfin shiner Cyprinella spiloptera, slimy sculpin Cottus cognatus, black crappie Pomoxis nigromaculatus, and yellow perch Perca flavescens. Juvenile Lasmigona costata were collected from one (slimy sculpin) of four fish species tested. Of eight fish species tested, Ligumia recta glochidia completely metamorphosed only on bluegill Lepomis macrochirus. Six of eleven species tested were found to be suitable hosts for S. undulatus glochidia: spotfin shiner, fathead minnow Pimephales promelas, bluegill, largemouth bass Micropterus salmoides, yellow bullhead, and black bullhead Ameiurus melas. Juvenile Anodontoides ferussacianus were collected from aquaria holding spotfin shiner and black crappie. Stuidies in 1994 combined with earlier studies at the University of Minnesota have identified several previously unknown suitable fish hosts for a variety of unionids.+ ' = R e t ~            m           ,     ) 6 b u       (!Hoxmeier, R.

Freshwater Q1 01604 Stock assessment and management; D 04668 Fish]The Alabama waters of the Tennessee River have historically contained abundant populations of paddlefish Polyodon spathula. During the later half of this century, overexploitation has reduced the number of paddlefish in the Tennessee River. We attempted to determine whether paddlefish populations in the Tennessee River within Alabama had recovered from this overexploitation since the implementation of a statewide moratorium in 1988. We failed to collect paddlefish after an effort of 346 gill-net-hours and 20 h of electrofishing pedal time from November 1993 through June 1994. Low abundance of paddlefish in the Tennessee River is likely the result of a combination of continuing commercial harvest in bordering states, loss of habitat, and slow recruitment due to a relatively old age at maturity. Recovery may require additional time, stocking, or both.n i z xqNov 1996 Issn 0275-5947 English Journal Article ASFA 1: Biological Sciences & Living Resources; Ecology Abstracts~/0*Kariba: The dubious benefits of large dams Balon, E. K. 1978 Ambioi7R2o 40-48b[The ecological consequences of dam building extend far beyond the common cost-benefit analysis. On the Zambezi River for example, a unique and stable ecological system, which took millenia to develop, was rapidly changed by dams into less productive lakes. The process was accompanied by widespread destruction and misery. The production of the electricity required for a more profitable export of mineral resources rendered the local inhabitants dependent on external sources of food, water, etc, where they had formerly been self-sufficient. The surface of the lake reflects more solar energy than the old terrestrial system. As a consequence, fish production is lower than the lost production of plants and game. Species diversity may be increased by natural invasion and artificial introduction, but the production limits of the system can not be changed.Freshwater environmental effects; dams; Africa, Kariba Dam ecosystems; Africa; Kariba Dam; human impact; effects on; freshwater ecosystems Q1 08482 Ecosystems and energeticshaUsing Smart Source Parsing English Journal Article ASFA 1: Biological Sciences & Living Resources,&Balon, E.

Forty-two species - 8 of them new for this part of the Danube - and 6 cyprinid hybrids were identified. Two distinct regions, above and below Ulm, were recognized for the upper Danube on the basis of both abiotic (distance from source, elevation, river gradient) and biotic (species richness, species distribution) characters of the localities. Nine species were distributed over most of the upper Danube, while 10 and 23 species were limited mostly to the upriver and downriver sections, respectively. A factor analysis of ecomorphological attributes for 28 dominant species revealed a generalist-specialist pattern among their swimming behavior and feeding modes.`Z1986 Issn 0378-1909 English Journal Article ASFA 1: Biological Sciences & Living Resourcesd]On the relations between hydrography and the ranges of freshwater fish species and subspeciesPBanarescu, P. M. Italian Journal of Zoology65 87-93eLFRanges of freshwater fish species depend on river basins. However, most species are confined to a limited area of a basin. Some limited distributions are determined by the ecology of the species, most have historical grounds. Many species are endemic to a restricted area of a river basin (e.g., 7 in the River Danube; more than 80 in the Mississippi river basin). Most non-endemics confined to a sector of a river basin also live in one or more adjacent basins. Cases are known of conspecific subspecies inhabiting distinct areas within a river basin, some of them being also present in a neighbouring basin. Restricted distributions are determined by the fact that river captures usually involve tributaries, not the main rivers and the inhabitants of the upper and middle reaches of the river do not disperse through the lower reaches. 1998Endemic species; Freshwater fish; Hydrology; Geomorphology; Biogeography; Pisces geographical distribution Freshwater Q1 01463 Habitat community studiesConference 9.

Marked changes in the community structure were identified. The most obvious were a decline in species diversity and a shift in species composition from a community with a preponderance of Alestes lateralis (Boulenger) (Characidae), to one dominated by cichlids. These changes were primarily due to members of the families Cyprinidae, Mormyridae and Schilbeidae being unable to adapt to the new environmental conditions, such as spawning and feeding grounds, and their inability to cope with fluctuating water levels in the lake. It was suggested that a sound fishery data collection system be implemented to provide reliable information on which to base management policy.   1 1991 Issn 0022-1112 English Journal Article ASFA 1: Biological Sciences & Living Resources; ASFA 3: Aquatic Pollution & Environmental Quality; Ecology AbstractsyV Ward, J.

Upstream-downstream interactions constitute the longitudinal dimension. The lateral dimension includes interactions between the channel and riparian/floodplain systems. Significant interactions also occur between the channel and contiguous groundwater, the vertical dimension. The fourth dimension, time, provides the temporal scale. Lotic ecosystems have developed in response to dynamic patterns and processes occurring along these four dimensions. An holistic approach that employs a spatio-temporal framework, and that perceives disturbances as forces disrupting major interactive pathways, should lead to a more complete understanding of the dynamic and hierarchical structure of natural and altered lotic ecosystems. 1989 Issn 0887-3593 English Journal Article ASFA 1: Biological Sciences & Living Resources; ASFA 2: Ocean Technology Policy & Non-Living Resourcesy>D>Regier, H.

Hatchlings (<1-day embryos) were positively rheotactic, photonegative, benthic, and vigorously sought cover. If denied cover, they exhibited vertical swim-up and drift behavior until cover was found. Older 1-8 day embryos exhibited the same behaviors as hatchlings; except when denied cover, they searched along the bottom until cover was found. The photonegative and cover seeking behaviors are adaptations that enable embryos to complete development while concealed under structure at a spawning site. Larvae 9-16 days old left cover and were positively rheotactic and photopositive. An estimated 75% of 9-14 day larvae left bottom cover and swam in the water column, suggesting that larvae, not embryos, initiate the downstream migration from a spawning site. Larvae were most active at night and preferred deep water and silt substrate. Most 43-66 day juveniles were benthic swimmers and, like larvae, positively rheotactic, photopositive, and nocturnally active. Behavior of embryos and larvae suggests shortnose sturgeon should be classified in the lithophil reproductive guild, not the litho-pelagophil guild.  ; Q 1995 Issn 0045-8511 English Journal Article Animal Behavior Abstracts; ASFA 1: Biological Sciences & Living Resources; Oceanic Abstracts,&Roe, K.

American shad, chinook salmon Oncorhynchus tshawytscha , sockeye salmon O. nerka and steelhead O. mykiss (formerly Salmo gairdneri) were counted and timed through various weir designs at different heads. American shad oriented toward surface flows, tending to reject submerged orifices as shallow as 2 m. The amount of time spent in the ladder by American shad depended on the head between pools. The species of salmonids tested were not significantly impeded by any of the weir designs or head differentials.            1989 Issn 0275-5947 English Journal Article ASFA 1: Biological Sciences & Living Resources; ASFA Aquaculture Abstracts; Oceanic Abstracts; Ecology Abstracts; Animal Behavior Abstractse Moring, J.

Fortunately, fisheries managers have numerous tools at their disposal. Fish culture has been an important component of management plans since the mid-1800s, but refinements in diet, disease control, growth, and survival are still needed. A critical concern for anadromous species is fish passage: maximizing survival for upstream and downstream-migrating fish. Computerized modelling exercises suggest that new techniques for diverting downstream fry, smolts, and spent adults may have a significant effect on survival, overall run numbers, and production. Genetic selection and improvements in stream habitat are also options available to fisheries managers to improve survival of wild and hatchery-produced fish. Further management options include some of the more innovative techniques, such as delayed release programs to promote localized sport fisheries. Fisheries managers must then decide how resources should be allocated. Along with this comes questions such as What is the optimal size of fish and time at release? How can the public become involved in habitat improvement and other restoration and enhancement programs? How can fisheries be improved through interagency and other types of cooperative management? These are the challenges in anadromous fish management.INLAND FISHERIES MANAGEMENT IN NORTH AMERICA., AMERICAN FISHERIES SOCIETY, BETHESDA, MD (USA), 1993, pp. 553-580 English Book Monograph ASFA 1: Biological Sciences & Living Resources Kynard, B. 1997`Life history, latitudinal patterns, and status of the shortnose sturgeon, Acipenser brevirostrum J &Environmental Biology of Fishesd48 1-46319-334sD=Life history; Acclimatization; Spawning; Migrations; Dams; Behaviour; Anadromous species; Acipenser brevirostrum; USA Marine; Brackish; Freshwater Q1 01342 Geographical distribution; Q1 01344 Reproduction and development; Q1 01604 Stock assessment and management; O 1050 Vertebrates, Urochordates and Cephalochordatesd]Historically, shortnose sturgeon inhabited most major rivers on the Atlantic coast of North America south of the Saint John River, Canada. Today, only 16 populations may remain. Major anthropogenic impacts on shortnose sturgeon are blockage of spawning runs by dams, harvest of adults (bycatch and poaching), dredging of fresh /saltwater riverine reaches, regulation of river flows, and pollution. The pattern of anadromy (adult use of salt water) varies with latitude. The pattern may reflect bioenergetic adaptations to latitudinal differences between fresh and salt water habitats for thermal and foraging suitability. The greater adult abundance in northern and north-central populations likely reflects a historical difference with southern populations that is currently accentuated by increased anthropogenic impacts on southern populations. Adult abundance is less than the minimum estimated viable population abundance of 1000 adults for 5 of 11 surveyed populations, and all natural southern populations. Across the latitudinal range, spawning adults typically travel to about river km200 or farther upstream. Dams built downstream of spawning reaches block spawning runs, and can divide amphidromous populations into up- and downstream segments. Conservation efforts should correct environmental and harvest impacts, not stock cultured fish into wild populations.9y1997 Issn 0378-1909 English Journal Article; Conference ASFA 1: Biological Sciences & Living Resources; Oceanic Abstractsd  Kynard, B. 1998tmTwenty-two years of passing shortnose sturgeon in fish lifts on the Connecticut River: what has been learned? *#Jungwirth, M.

Some lower river pre-spawning adults annually migrate to the dam, enter fish lifts and are passed upriver. I examined the passage pattern of 97 migrants lifted from 1975 to 1996. The annual number of fish passed was 0-16 (mean = 4.4, SE = 0.86, mode and median = 4 ind/yr). There was no trend in annual abundance during the 22 year period. Most fish (N = 67) were lifted individually during a day. Adults were passed each month that the lift operated (April-October). Fish were lifted at water temperatures of 10 to 27 oC, with 86% lifted between 12 and 23 oC. River discharge may affect when fish migrate upstream, or enter the lift, or both, e.g. 60 of 71 dates that fish passed were within 23 days (mean -8.5 days, 95% CI = 6.9-10.2 days) following a river discharge > 600 m3/s. Most fish entered during decreasing discharge of 200-450 m3/s (mean = 312 m3/s). Fish were passed by the spillway lift where water depth at the entrance is more shallow than at the tailrace lift entrance. Shortnose sturgeon passage can be enhanced by improving the approach route to the spillway lift, lifting migrants during late May-October when fish are in good physiological condition, increasing lift frequency and attraction flow during summer and fall, and increasing efforts to pass fish within 10 days following natural discharge that exceeds 600 m3/s.r  -                    Conference Fish Migration and Fish Bypass Channels Symp., Vienna (Austria), 24-27 Sep 1996 Fish Migration and Fish Bypasses, Fishing News Books, 1998, pp. 255-266 Price: pound sterling 65.

For a fish ladder to be effective, migrating fish must be attracted to the fishway entrance. To attract fish, a large volume of "attraction" flow is added to the relatively small fishway flow just inside the fishway entrance, and the combined flow discharges to the tailrace as a plume, which attracts upstream-migration fish such as Atlantic salmon Salmo salar and American Shad Alosa sapidissima . The common methods of providing attraction flow are pumped flow lifted to the fishway from the tailrace and gravity flow dropping from the forebay pond. Both options are net users of power, since pumps consume electric power and gravity flow uses water which has the potential to generate electricity. At Wilder Dam, a 17-m head had to be dissipated. Two options were studied: energy-dissipating valves and chambers; and a small hydroturbine. Both did the job; however, the energy-dissipating valve is an energy waster, whereas the hydroturbine drives a 3,200-kW hydroelectric generator, producing economic benefits that offset its cost. The fishway turbine-generator has the additional benefits of providing year-round low-flow augmentation at peak generating efficiency and increased base-load generation during high-flow periods.

The River Continuum Concept (RCC) represents a synthesis of these ideas. Suggestions are made for clarifying, expanding, and refining the RCC to encompass broader spatial and temporal scales. Factors important in this regard include climate and geology, tributaries, location-specific lithology and geomorphology, and long-term changes imposed by man. It appears that most riverine ecosystems can be accommodated within this expanded conceptual framework and that the RCC continues to represent a useful paradigm for understanding and comparing the ecology of streams and rivers. 1985 Issn 0706-652x Incl. bibliogr.: 134 ref.

Since 1970 A. implicata has increased its range upstream in the Connecticut River to Bellows Falls, Vermont. This rapid range expansion appears to be correlated with chronological episodes of clupeid fish restoration above successive dams in the Connecticut River. Anodonta implicata, therefore, can be used as an indicator of success of clupeid fish restoration.        RK1985 English Journal Article ASFA 1: Biological Sciences & Living Resources LESoloman, R.

Construction of locks and dams supplemented by dredging and bank stabilization was required to maintain the 9-ft depth, particularly during periods of low flow. An investigation was performed by Colorado State University to evaluate the river reaches before and after man-made changes and overall changes in geomorphology. Additionally, trends of future geomorphic changes that could result from existing and potential future developements were addressed with the aid of a mathematical simulation model. Vegetation and vegetative successional patterns of the floodplain were characterized by the Missouri Botanical Gardens. Vegetation maps were produced delineating vegetational communities adjacent to the rivers and on islands. An inventory of the animals and their habitats was conducted by Southern Illinois University. Seven habitats were distinguished in the unprotected floodplain. Based on literature, 49 species of mammals, 286 species of birds, and 81 species and subspecies of amphibians and reptiles were expected to occur in the study area. Members of the Waterways Experiment Sttion study team collected water and sediment samples for chemical and physical analysis and biological samples from four habitat types. The data were subjected to various statistical analyses to determine if there were differences between habitats and sampling dates. Fish samples were collected from the Illinois River by the Illinois Natural History Survey and results were compared with literature to determine temporal and spatial changes in distribution. The overall impacts of operation and maintainance of the 9-ft channel were discussed relative to the effects on the biological, chemical, and physical system in the study area. Recommendations were made for further studies that are needed to define impact more adequately.Available from the National Technical Information Serivce, Springfield VA 22161 as AD-A017 865, Price codes: A05 in paper copy, A01 in microfiche.

Paddlefish movement and habitat use were investigated by radio-telemetry. Fish were surgically implanted with 49 MHz radio transmitters and released at capture site in Pool 13. Radio-tagged fish measured 68 to 96 cm, eye to fork length, and weighed 4 to 18 kg. Seven paddlefish were monitored during the summer of 1980, and 10 fish were tracked through the spring and into the summer of 1981. Tracking was conducted primarily by boat, with a single search by aircraft for lost fish 1981. Physical characteristics of the habitat measured at telemetry location sites were: water depth, current velocity, water temperature, bottom contour, and proximity to navigation improvement structures. Paddlefish exhibited great mobility, especially during the spring months. Individual linear range varied from 12.5 to 104.6 km during the study period. Interpool movement through navigation dams was observed. Group movement upstream through Lock and Dam 12 occurred when dam gates were raised during a high water period in the spring, 1981. Movement downstream through Lock and Dam 12 was accomplished when dam gates were partially closed. Movement from and subsequent return to specific areas suggested recognition of particular habitats. Main channel border and tailwater habitats were utilized most frequently, although telemetry locations were also made in backwater, main channel, and side channel habitats. Association with wing dams was observed.

An experimental device caught 6 276 eels for 180,5 hours. The range size of eels varied from 120 to 395 mm (mean length: 223 mm) which is smaller than range size of eels caught by a neighbouring fish ladder. This result seems to show the selectivity of usual fishways. Various configurations of the experimental device allowed to test some selectivity factors. Slope and substrate factors seem to influence the efficiency. For a given slope, the eel size distribution depends on the substrate, more dense brushes involve a smaller average length of migrants. Selectivity also changes according to gradients. Slight slopes (15-30 degree ) should be recommended for such devices and the substrate should be adapted to size distribution of eels in migration.n N _ Original Title Note technique -- etude de quelques facteurs de selectivite de passes a anguilles 1992 Issn 0767-2861 French Journal Article ASFA 1: Biological Sciences & Living Resources Lein, G.

Tagging studies, characterization of spawning migrations, and comparative analyses of catches suggested that paddlefish in the Tallapoosa and Cahaba rivers represented functionally discrete populations that reside in the adjacent reservoirs. Variation in population characteristics appeared to be related to differences in the hydrologic and thermal regimes of the two study rivers and to differences in historical exploitation of populations in the two resident reservoirs. Growth (calculated via back-calculated body length at age) differed between populations in the upper and lower Alabama River, probably reflecting the relatively lentic (upper) and lotic (lower) nature of habitats in these two reaches. Life history characteristics of paddlefish in the Alabama River drainage differed from fish in the Mississippi River drainage. Growth, fecundity, spawning frequency, and age at maturity all were advanced for Alabama River fish relative to Mississippi River fish, whereas maximum age and size of Alabama River fish were less than had been previously reported for populations in the Mississippi River drainage. Differences between populations in the two drainages may reflect geographic variation in biotic and abiotic variables as well as long-term geographic and reproductive isolation.u    xqMay 1998 Issn 0002-8487 English Journal Article Ecology Abstracts; ASFA 1: Biological Sciences & Living Resourcesi+4.Katopodis, C.

For the standard design of the simple Denil, an equation has been developed between the dimensionless discharge Q* and the relative depth of flow d/b for d/b as large as 5.5. The normalized velocity distributions in the centerplane of the Denil were found to have certain shapes depending upon the d/b ratio. For the nonstandard designs of the Denil fishway, based on the results of about 660 experiments, a method has been found to predict not only the relation between Q* and d/b but also the normalized velocity profiles in the centerplane of the Denil. The coefficient of friction between the central stream in the Denil and the circulating water on the sides as well as the bottom has been evaluated along with the equivalent Manning's n for the Denil fishway. These results are believed to be important in extending the depth range of the standard Denils as well as making changes to the standard Denil for passing different species of fish.i  @ J @K Jul 1997 Issn 0733-9429 English Journal Article Water Resources Abstracts; ASFA 2: Ocean Technology Policy & Non-Living Resourcesn$Keenlyne, K.

Six measurements were made on 89 pallid and 204 shovelnose sturgeons. Means of several morphometric characteristics were statistically different between populations of both species. Pallid sturgeon means showed proportional trends relative to location on the river. Toward the headwaters, relative head and interrostral lengths were progressively shorter and outer barbel length relatively longer. The only trend observed for the shovelnose sturgeon was that relative head length became longer upriver. This was the opposite of the trend observed for the pallid sturgeon. Morphometric ratios commonly used to differentiate the two species were useful measures for live fish from isolated populations of Missouri River sturgeon but not for the overall sturgeon population. The exclusivity of morphometric ratios currently used to distinguish between the two species did not hold for our larger fish and large sample size. A cumulative morphometric characteristic index is described to aid managers in comparing individual fish within a composite sturgeon population, and the finding of three possible hybrids is discussed.

Three fishes each were held at 4.5, 10, and 15.5 oC; five fish were held at 21 oC. By 64 days, metamorphosed juveniles were found in the 15.5 and 21 oC trials but not in the 5.5 and 10 oC trials, indicating that the lower threshold temperature for metamorphosis was between 10 and 15.5 oC for the duration. In a second experiment, largemouth bass were infected with glochidia of L. cardium and held at 10 oC. A sample of fishes was removed monthly and brought to 21 oC. Numbers of glochidia that metamorphosed after being warmed were compared to the number that metamorphosed without warming. The percentage that metamorphosed after warming decreased linearly with time. At one month, 100% of the glochidia metamorphosed after warming. This decreased to 80% by two months, to 30% by four months and 3% by six months. Although this post-warming percentage decreased with time, the total percentage of metamorphosed juveniles (at all temperatures) was not correlated with time. Controls kept at 21 oC required three weeks to reach peak metamorphosis, but test subjects subjected to 10 oC required less than nine days to metamorphose once warmed. Many overwintering glochidia therefore complete a portion of their development on the host at winter temperatures, but stop short of excystment. Some glochidia metamorphosed without being warmed, but this phenomenon is not understood. This study confirms that glochidia may overwinter on hosts, with some glochidia persisting for more than six months before metamorphosing when warmer conditions return.

These inflection points travel down the body at the speed of the running wave of bending. In movements with increasing amplitudes, the body rotates around the inflection points, inducing semicircular flows in the adjacent water on both sides of the body that together form proto-vortices. Like the inflection points, the proto-vortices travel towards the end of the tail. In the experiments described here, the phase relationship between the tailbeat cycle and the inflection point cycle can be used as a first approximation of the phase between the proto-vortex and the tailbeat cycle. Proto-vortices are shed at the tail as body vortices at roughly the same time as the inflection points reach the tail tip. Thus, the phase between proto-vortex shedding and tailbeat cycle determines the interaction between body and tail vortices, which are shed when the tail changes direction. The shape of the body wave is under the control of the fish and determines the position of vortex shedding relative to the mean path of motion. This, in turn, determines whether and how the body vortex interacts with the tail vortex. The shape of the wake and the contribution of the body to thrust depend on this interaction between body vortex and tail vortex. So far, we have been able to describe two types of wake. One has two vortices per tailbeat where each vortex consists of a tail vortex enhanced by a body vortex. A second, more variable, type of wake has four vortices per tailbeat: two tail vortices and two body vortices shed from the tail tip while it is moving from one extreme position to the next. The function of the second type is still enigmatic.id^Dec 1999 Issn 0022-0949 English Journal Article ASFA 1: Biological Sciences & Living Resources$Von Oettingen, S.

This faunal group has been characterized as 6 percent extinct, 19 percent threatened or endangered, and 23 percent as potentially warranting federal protection. No other widespread group of animals in North America approaches this level of faunal collapse. At an April 1995 meeting of representatives from several federal and state natural resources agencies and the commercial mussel industry, the magnitude and the immediacy of threats, nationwide, to our native freshwater mussel fauna was recognized. The group agreed that a coordinated effort of national scope was needed to prevent further mussel extinctions and population losses. To address these needs, the group decided to: 1) draft a national strategy for the conservation of native freshwater mussels; and 2) establish a national ad hoc committee with broad based representation from state, tribal and federal agencies, the mussel industry, private conservation groups, and the academic community to help implement mussel conservation at the national level. A draft national strategy was presented in October 1995 at a national mussel symposium in St. Louis, Missouri. I will discuss the strategy and the results of the first ad hoc committee meeting scheduled for February 1997.ujdConference 89.

Ucrit60 (the highest speed maintainable for 60 min) values ranged from 0.30 to 0.73 m/s and increased significantly with length and temperature. Ucrit10 (the highest speed maintainable for 10 min) values ranged from 0.43 to 1.14 m/s and also increased significantly with fish length and water temperature. When startled, walleye were able to attain higher speeds (1.60-2.60 m/s) during short (temperature-independent) bursts of swimming activity. The relatively low Ucrit60 values suggest that walleye possess a narrow scope for aerobic activity compared with other species, which may account for their poor performance in fishways. However, the small differences between Ucrit60 and Ucrit10 values and the large differences between Ucrit10and fast-start performance suggest that low passage efficiency may be caused by a behavioural disinclination to switch from low to high intensity activity. ! 5     @  @  @  @  @  @ Sep 2000 Issn 0008-4301 English Journal Article Ecology Abstracts; Animal Behavior Abstracts; ASFA 1: Biological Sciences & Living Resources "Pearson, W.D.

Three native fishes (Acipenser fulvescens, Alosa alabamae, and Ammocrypta asprella) have apparently been eliminated from the river. The Ohio River fish community was severely affected by the siltation of clean gravel substrates, and the inundation of those substrates by the canalization of the river before 1927. In the past 20-30 years, populations of many species have increased, particularly in the upper third of the river. Some pollution-intolerant species which had disappeared from the upper reaches of the river between 1900 and 1950 have been returning since 1970 (e.g. Polyodon spathula, Hiodon tergisus, and Carpiodes velifer). A few pollution-tolerant species have declined in abundance since 1970 (e.g. bullheads and Ictalurus catus). The most abundant fishes in the lock chamber samples of 1957-87 were Notropis atherinoides, Dorosoma cepedianum, Aplodinotus grunniens, Notropis volucellus, and Ictalurus punctatus. The ongoing recovery of the Ohio River fish community should encourage us to take additional steps to protect the river from catastrophic spills of toxic materials and to reintroduce eliminated native fishes. ~            D S            xqOhio Journal of Science OJSCA9 Vol. 89, No. 5, p 181-187, December 1989. 3 tab, 46 ref.

Freshwater Q1 01421 Migrations and rhythms; Q1 01344 Reproduction and development; Q1 01604 Stock assessment and management; SW 5040 Data acquisitionaSince 1979, abundances of sauger Stizostedion canadense have declined in the Tennessee River system. Reasons for this decline may include overharvest, loss of spawning habitat, and low recruitment due to extreme flows. The purpose of this study was to investigate the movements of saugers following winter concentration below Pickwick Dam, Tennessee. Thirty-seven saugers were implanted with radio transmitters directly below Pickwick Dam and were tracked between December 1992 and June 1993. Four saugers moved upstream through the locks at Pickwick Dam; the remaining fish stayed within the first 30 km of the tailwater throughout the spawning season. Three areas below Pickwick Dam were identified as possible March prespawn staging sites. After April 1, saugers in the tailwater area began a rapid downstream migration to the main basin of Kentucky Lake. Some fish moved downstream more than 200 km in less than 10 d in this semiclosed system. Movements encompassed four states (Kentucky, Tennessee, Mississippi, and Alabama) along the Tennessee River system, underscoring the need for interjurisdictional management.t ! 7 yAug 1997 Issn 0275-5947 English Journal Article ASFA 1: Biological Sciences & Living Resources; Water Resources AbstractstH D*$Junk, W.L. Bayley, P.B. Sparks, R.E. 1989:3The flood pulse concept in river-floodplain systemst  Dodge, D.P.<6Proceedings of the International Large River Symposium D>Canadian Special Publication of Fisheries and Aquatic Sciences 106 110-127JDflood pulse concept paradigms regulated rivers management ideologies The principal driving force responsible for the existence, productivity, and interactions of the major biota in river-floodplain systems is the flood pulse. A spectrum of geomorphological and hydrological conditions produces flood pulses, which range from unpredictable to predictable and from short to long duration. Short and generally unpredictable pulses occur in low-order streams or heavily modified systems with floodplains that have been levied and drained by man. Because low-order stream pulses are brief and unpredictable, organisms have limited adaptations for directly utilizing the aquatic/terrestrial transition zone (ATTZ), although aquatic organisms benefit indirectly from transport of resources into the lotic environment. Conversely, a predictable pulse of long duration engenders organismic adaptations and strategies that efficiently utilize attributes of the ATTZ. This pulse is coupled with a dynamic edge effect, which extends a "moving littoral" throughout the ATTZ. The moving littoral prevents prolonged stagnation and allows rapid recycling of organic matter and nutrients, thereby resulting in higher productivity. Primary production associated with the ATTZ is much higher than that of permanent water bodies in unmodified systems. Fish yields and production are strongly related to the extent of accessible floodplain, whereas the main river is used as a migration route by most of the fishes. In temperate regions, light and/or temperature variations may modify the effects of the pulse, and anthropogenic influences on the flood pulse or floodplain frequently limit production. A local floodplain, however, can develop by sedimentation in a river stretch modified by a low head dam. Borders of slowly flowing rivers turn into floodplain habitats, becoming separated from the main channel by levees. The flood pulse is a "batch" process and is distinct from concepts that emphasize the continuous processes in flowing water environments, such as the river continuum concept. Floodplains are distinct because they do not depend on upstream processing inefficiencies of organic matter, although their nutrient pool is influenced by periodic lateral exchange of water and sediments with the main channel. The pulse concept is distinct because the position of a floodplain within the river network is not a primary determinant of the processes that occur. The pulse concept requires an approach other than the traditional limnological paradigms used in lotic or lentic systems. Junk, W.J. 1999HBThe flood pulse concept of large rivers: learning from the tropics Large Rivers113261-280River-floodplain systems are specific ecosystems with very complex land-water interactions and a highly adapted flora and fauna. In temperate zones, they have been intensively modified by man for many decades, and only small areas are left in a relatively undisturbed condition. Furthermore, the impact of the flood pulse is often camoflagued by the annual temperature/light pulse. In the humid tropics there are still large undisturbed river-floodplain systems, where the impact of the flood pulse can be studied without the interference of the temperature/light pulse. The flood pulse concept is presented and its implications for temperate river-floodplain systems are discussed." 5P4  Coker, R.E. 1929B;Keokuk dam and the fisheries of the Upper Mississippi River.

To calculate swimming speed, distance moved and time elapsed were measured with a digital spectrum processor using near real-time spectrum analysis. This device was designed to be used in a coprocessing arrangement with a receiver, thereby providing pulse position code discrimination, verification and continuous data storage. Radio-tagged adults (48.3 to 54.8 cm long) voluntarily swam against water velocities, ranging from 1.32 to 2.85 m s-1, in an 18 m long flume at a mean water temperature of 10.1 plus or minus 1.6 oC. At water velocities of 1.32-1.55 m s-1, individuals successfully ascended the flume at swimming speeds of 1.61-2.55 m s-1, or 3.30-4.79 body lengths per second (l s-1), respectively. At high water velocities ranging from 1.92 to 2.85 m s-1, individual swimming speeds increased from 2.55 to 3.60 m s-1, or 4.94-7.27 l s-1, respectively. However, above a threshold value of 1.92 m s-1, individuals traversed shorter distances and were unable to ascend the flume. The highest swimming speed observed was 4.13 m s-1, or 8.35 l s-1. The results of this study indicate that in addition to its applicability in the determination of burst swimming speeds, digital telemetry could prove a useful tool in the design and evaluation of future fishways and culvert installations. . 9 >  @            6  8                   Feb 1998 Issn 0886-9375 English Journal Article Water Resources Abstracts; ASFA 1: Biological Sciences & Living Resources; Animal Behavior Abstracts Colt, J.
