Common name: Redside Dace
available through www.itis.gov
Identification: Page and Burr (1991).
Size: 12 cm.
Native Range: Upper Susquehanna drainage, New York and Pennsylvania; Great Lakes (except Lake Superior) and Mississippi River basins from New York and southern Ontario to Minnesota and south to West Virginia, northern Kentucky, Indiana, Wisconsin, and Iowa (Page and Burr 1991).
Hendricks et al. (1979) reported the collection of a single specimen of the Redside Dace Clinostomus elongatus in Bear Creek, a tributary of the Youghiogheny River (Monongahela River drainage) in Maryland. Although these authors noted that the species is native to the drainage, they stated that the Maryland specimen may represent a bait bucket introduction. One of several reasons given was that the site, Bear Creek, is a popular fishing stream stocked with trout. Lee et al. (1980 et seq.) apparently considered the Maryland site to represent part of the native range of C. elongatus.

† Populations may not be currently present.
Means of Introduction: Probable bait release.
Status: Reported in Maryland.
Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
