Osmerus mordax   (Mitchill 1814)

Common Name: rainbow smelt

Taxonomy: available through ITIS logo

Identification: Scott and Crossman (1973); Becker (1983); Smith (1985); Page and Burr (1991).  

Size: 33 cm.

Native Range: Atlantic drainages from Lake Melville, Newfoundland, to Delaware River, and Pennsylvania; Arctic and Pacific drainages from Bathurst Inlet, Northwest Territories, to Vancouver Island, British Columbia. Also, Pacific drainages of Asia (Page and Burr 1991). The origin of Osmerus mordax in Lake Ontario is disputed, as they are thought to be either native or introduced from the Atlantic through the Erie Canal (Mills et al. 1993). Another alternative is that O. mordax migrated downstream from the upper Great Lakes, where it is considered nonindigenous

Established in Lake Superior at Thunder Bay, Ontario, Canada (Yule, personal communication 2005).
 

Means of Introduction:

The earliest known record is from 1912, when eggs were stocked in Crystal Lake, Michigan, which drains into Lake Michigan (Van Oosten 1937). Fish escaped into Lake Michigan and spread quickly throughout the Great Lakes and their tributaries (Creaser 1926; Gerking 1945; Hubbs and Lagler 1947; Nelson and Gerking 1968; Christie 1974; Eddy and Underhill 1974; Smith 1979; Morrow 1980; Phillips et al. 1982; Cooper 1983; Emery 1985). Early records documenting the smelt's range expansion in the Great Lakes include Lake Michigan, 1923 (Christie 1974; Emery 1985), Lake Erie, 1935 (Cooper 1983; Smith 1985), Lake Huron, 1925 (Christie 1974; Eddy and Underhill 1974), Lake Ontario, 1929 (Christie 1974; Smith 1985), and Lake Superior, 1923 (Emery 1985). The Lake Ontario population may be either native to this lake or migrated downstream, possibly through the Welland Canal. (Emery 1985; Smith 1985). Another possibility is that the species was introduced from the Finger Lakes via the Seneca-Cayuga, Erie and Oswego canals (Smith1985).

Two means have been proposed to explain the introduction of rainbow smelt into the Missouri and Mississippi rivers. It may have spread from Lake Michigan via the Chicago sanitary canal to the Illinois River and then to the Mississippi and Missouri rivers (Burr and Mayden 1980). Alternatively, the species may have gained access to these rivers as a result of a stocking at Lake Sakakawea, North Dakota, in 1971 (Bouc 1987; Mayden et al. 1987; Holton 1990). The second explanation seems more plausible because of a lack of records from the Illinois River. Records of first occurances in other areas include the Mississippi River, Illinois and Kentucky, 1978; Mississippi River, Louisiana, 1979; Mississippi River, Tennessee and Arkansas, 1980; Missouri River, Missouri, 1980; Missouri River, Kansas, 1982 (Mayden et al. 1987). Mayden et al (1987) provided a map of the species' distribution, dates of first observation in new areas, and possible introduction pathways. The species was originally introduced into Lake Sakakawea, North Dakota, as a forage for salmonids (Mayden et al. 1987).

Status: Introduced populations of this species have been very successful and the rainbow smelt is now established in the Great Lakes and in most rivers and lakes where introduced. This species has done so well in the Great Lakes that a commercial fishery targeting smelt has been operating there for many years (Smith 1985). It is the most abundant fish in some samples taken from the Mississippi River (Pflieger 1997). Nevertheless, no adults of the rainbow smelt have been found in either Missouri (Pflieger 1997) or Tennessee (Etnier and Starnes 1993). As such, Pflieger (1997) concluded that populations in Missouri are maintained by continued escape of fish from upstream reservoirs on the Missouri River. As of 1987, only one specimen had been taken from the Ohio River (Mayden et al. 1987). It is considered extirpated in Georgia; the species has not been observed in that state since its release (Dahlberg and Scott 1971b). 

Impact of Introduction: In the Great Lakes, rainbow smelt compete with lake herring Coregonus artedii for food (Becker 1983). Christie (1974) supplied some evidence to support this, correlating lake herring decline with smelt increases in most of the lakes. Todd (1986b) also reported that smelt may be partially responsible for the decline of whitefish Coregonus spp. in the Great Lakes. Havey (1973) reported increased growth of landlocked Atlantic salmon following the introduction of smelt as a forage species in a lake in Maine. Hrabik et al. (1998) found evidence of competition for food between introduced rainbow smelt and native yellow perch Perca flavescens in Wisconsin lake habitats. Stedman and Argyle (1985) found the diet of O. mordax to include young-of-the-year fish. The species that were consumed by O. mordax depended upon the prey availability (Stedman and Argyle 1985). Stedman and Argyle (1885) discovered that in Lake Michigan in late October of 1982, O. mordax consumed bloaters (Coregonus hoyi) and alewives (Alosa pseudoharegus). The authors also noted that although O. mordax does not appear to have had an impact on bloater populations in the last five years, future impact is possible. A study on nighttime consumption of O. mordax in Lake Ontario revealed their primary food source to be slimy sculpin (Cottus cognatus) and opossum shrimp (Mysis relicta) (Brandt and Madon 1986). Juvenile lake trout (Salvelinus namaycush) rely heavily on C. cognatus, competing directly with O. mordax, while adult S. namaycush consume O. mordax (Brandt and Madon 1986). The authors point out that S. namaycush may be a keystone predator in the relationship between O. mordax and C. cognatus.

Remarks: This species is eaten by humans and used as bait for salmonids and walleye (Pflieger 1997).
