Distribution of Fishes in the Red River of the North Basin on Multivariate Environmental Gradients
Cyprinidae
Bluntnose Minnow
Pimephales notatus (Rafinesque), the bluntnose minnow, was collected by Woolman (1896) from the Goose, Sheyenne, Otter Tail, and Buffalo Rivers and Daugherty Creek, a tributary to Lake Traverse, where it was rare to common in the samples (Figure A40). Hankinson (1928) listed Hyborhynchus notatus from the Sheyenne River and described it as uncommon in North Dakota. Hubbs and Schultz also collected it from the Sheyenne River in 1926 (UMMZ 1994); and Olson (1932) listed the species from the Red Lake, Clearwater, and Wild Rice Rivers in Minnesota. The bluntnose minnow has been taken primarily from the Forest, Sheyenne, and Otter Tail Rivers, with scattered reports from several other streams. The species has been present at 13% of the stream sites sampled in the basin since 1962, but it has been most common in reaches of the NCH ecoregion, where it has occurred at 31% of sites. The bluntnose minnow has typically been common in samples, and as many as 125-150 individuals have been taken at sites west of Otter Tail Lake (Otter Tail River).
