COSEWIC status appraisal summary on the river redhorse, Moxostoma carinatum, in Canada

18 Feb 2016

'This freshwater fish species occurs in rivers in densely populated regions of Ontario and Quebec. Although collected at new locations in both Ontario and Quebec, the species has likely been extirpated from several rivers within its range. It comes close to meeting Threatened criteria due to a small area of occupancy and relatively few locations. Its persistence is limited by barriers to movement, altered flow regimes, turbidity, eutrophication and habitat deterioration from agriculture and industrial activities. The species may become Threatened if these threats are neither reversed nor managed with demonstrable effectiveness”--p. iii.
