Status of the Golden Redhorse, Moxostoma erythrurum, in Canada

Abstract

The Golden Redhorse, Moxostoma erythrurum , is known from the Lake Huron, Lake St. Clair, and Lake Erie drainages in southwestern Ontario. Recent records from the Niagara River in Ontario and the Red River in Manitoba, indicate that its range is either expanding or more extensive than had previously been thought. This species is difficult to identify and is often overlooked or misidentified. Three other species of Moxostoma are either threatened or rare in Canada. Canadian populations are contiguous with those in the United States, but at the northern limit of the range of the species. Little is known of its biology in Canada, but it does not appear to be in great jeopardy at this time
