The black redhorse (Moxostoma duquesnei, also duquesnii, duquesni) is a species of freshwater fish endemic to Ontario and the eastern half of the United States, where it lives in streams and small to medium rivers. A bottom-feeder, it feeds on microcrustaceans, aquatic insects, detritus, and algae. The black redhorse spawns in the spring.
