Ictiobus niger (Rafinesque, 1819)

The black buffalo (Ictiobus niger) is a North American species of freshwater fish in the Catostomidae or sucker family.I. niger is found in the Mississippi Basin and southern Great Lakes. I. niger was first discovered in Canada in the western end of Lake Erie and has been reported from Boston Creek. The Tennessee distribution ranges from rivers and streams in the Cumberland Mountains, a few rivers in middle Tennessee, and in west Tennessee along the Mississippi River. The ecology of the species is quite similar to that of I. bubalus. I. niger has a ventrally positioned mouth, making the species’ diet benthic-oriented.I. niger has a distinct shape that mocks I. bubalus and I. cyprinellus considering it a hybrid between the two species.

I. niger is found in large and small rivers in eastern North America from the Mississippi Basin to Canada. In Canada, the species was first described in Lake Erie. In the United States, the species is found in both small and large rivers in the basins of the Mississippi, Missouri, and Ohio as well as in southern Lake Michigan and Lake Erie. Among others, I. niger is native to Iowa, South Dakota and Minnesota; more southern states include eastern Texas and Oklahoma.
