Catostomidae
Bigmouth Buffalo
Ictiobus cyprinellus (Valenciennes), the bigmouth buffalo, was first reported
by Copes and Tubb (1966) and Tubb et al. (1965) from the lower reaches of the
Pembina, Forest, Maple, Sheyenne, and Wild Rice Rivers of North Dakota (Figure
A12). The species has been most common in the Red, Bois de Sioux, Rabbit,
and Otter Tail Rivers in the southern portion of the basin. The bigmouth buffalo
has been reported at 12% of stream sites sampled in the RRV ecoregion since
1962 (Table 4).
