Recovery Strategy and Action Plan for the Black Redhorse (Moxostoma duquesnei) in Canada

The Black Redhorse is a member of the sucker family (Catostomidae) and is one of seven redhorse species found in Canada. Black Redhorse typically grows to an average length of 40 cm, making it one of the smaller redhorse species found in Canada. The species has an olive, gold or brassy dorsal surface with paler sides and a silver or white ventral surface. Its range is limited to eastern North America, where it is found in the Mississippi and Great Lakes basins. In Canada, the species is restricted to southwestern Ontario, specifically, tributaries of Lake Huron (Sauble, Saugeen, Maitland, Bayfield, and Ausable rivers), Lake St. Clair (Thames River), and Lake Erie (Grand River). The Black Redhorse plays a role in benthic-pelagic coupling as it transfers energy from the benthic food web where it feeds, to the pelagic food web where it is preyed upon by piscivorous fishes.
