Fish
(Diadromous, Freshwater, and Saltwater) - Fish, aquatic vertebrates which are covered in scales and equipped with fins (paired and unpaired), are found in all types of aquatic environments ranging from freshwater to saltwater. Diadromous fish are those that travel between fresh and saltwater (Pacific salmon, for example, which is an anadromous fish that breeds in freshwater but lives in the sea, mostly). Monitoring the abundances of the prey fish populations is critical to managing the lake ecosystem. Presently, salmonines are stocked into the lake to supplement and sustain their populations within the lake.

Black Salty: Implications of survival of non-native live salt-water bait
The black salty is simply a variety of goldfish. Goldfish are non-native fishes from Asia that can disrupt natural habitats by interfering with feeding and reproduction of native fishes. Non-native fishes may compete with the young of game species that use estuaries as nurseries. Once a population of non-native fish is introduced and reproducing in a natural habitat, they are very difficult or impossible to eliminate.

Development of Methods to Determine the Reproductive Status of Pallid Sturgeon in the Missouri River

Publisher: USGS | Science Center: Columbia Environmental Research Center (CERC, Columbia) | Format: URL

www.cerc.usgs.gov — This research project focuses on the endemic nature of the Pallid sturgeon (Scaphirhynchus albus) and shovelnose sturgeon (Scaphirhynchus platorynchus) and their reproductive status. Its objectives are to develop methods to use endoscopy and ultrasonic imagery to visually observe the gonads of adult and immature shovelnose and pallid sturgeon, as More...

Fish Health and Reproductive Studies at Lake Erie Areas of Concern

Publisher: USGS | Science Center: Leetown Science Center (LSC, Kearneysville) | Format: URL

www.lsc.usgs.gov — This is a research project whose primary objective is to assess the health of selected fish species (brown bullhead and largemouth bass) and compare these findings with historic information on fish health in the individual rivers and with concurrent samples collected at reference sites. A secondary objective is to compare and correlate the fish More...

Effects of estrogen and related contaminants on the expression of genes involved in the innate immune system of fish in rivers of the Chesapeake Bay Drainage

Publisher: USGS | Science Center: Leetown Science Center (LSC, Kearneysville) | Format: URL

www.lsc.usgs.gov — This research project measures the effects of estrogen and related contaminants on the expression of genes involved in the innate immune system of fish in rivers of the Chesapeake Bay Drainage. This project begs the question of whether or not hepcidin are expression and iNOS expression induced upon exposure to bacteria, and whether this induction More...

Development of a Bioassay to Quantify Vitellogenin in the Endangered Razorback Sucker followed by Annual Cycle Characterization of Vitellogenin and Steroid Hormones as a Measure of Reproductive Health

Publisher: USGS | Science Center: Columbia Environmental Research Center (CERC, Columbia) | Format: URL

www.cerc.usgs.gov — This research project objective is to measure vtg and steroid hormones in sexually mature, adult razorback sucker over one annual -estradiol,ß reproductive cycle. We will measure vtg and steroid hormones (17 11-ketotestosterone, and testosterone) in blood plasma of razorback suckers once a month for one year to document concentrations throughout More...

Investigation of Organic Chemicals Potentially Responsible for Mortality and Intersex in Fish of the North Fork of the Shenandoah River, Virginia, during Spring of 2007

2008 | Publisher: USGS | Format: URL

pubs.usgs.gov — This study determined that concentrations of persistent hydrophobic contaminants, such as polycyclic aromatic hydrocarbons (< picograms per liter), legacy pesticides (<10 picograms per liter), and polychlorinated biphenyls (<280 picograms per liter) were low and indicative of a largely agricultural area. Atrazine and simazine were the most More...

Relations between and among contaminant concentrations and biomarkers in black bass (Micropterus spp.) and common carp (Cyprinus carpio) from large U.S. rivers, 1995-2004

2008 | Publisher: Other (RSC Publishing, Journal of Environmental Monitoring) | Format: URL

www.rsc.org — Environmental contaminant and biomarker monitoring data from major U.S. river basins were summarized for black bass (Micropterus spp.) and common carp (Cyprinus carpio) sampled over a nine year period. Cumulative frequency distributions revealed taxon differences for many organochlorine residue concentrations, elemental contaminant concentrations, More...
