COSEWIC Assessment and Status Report on the River Darter Percina shumardi - Saskatchewan – Nelson River populations Southern Hudson Bay – James Bay populations - Great Lakes-Upper St. Lawrence populations in Canada (2017)River Darter (Percina shumardi) is a small, elongated fish that can be distinguished from other darters by scaled cheeks and operculum and a well-marked dark spot on the upper anterior and lower posterior corners of the spiny dorsal fin. The breast is scaleless, and there are 46-62 lateral line scales. The anal fin of males is enlarged reaching almost to the caudal fin. River Darter is a little known species and has no direct economic importance; however, it can be numerous in larger rivers and near the shore of larger lakes in Manitoba and northwestern Ontario and likely plays an important ecological role where abundant. It is ranked as Critically Imperilled in portions of its distribution in the United States.
