Distribution of Fishes in the Red River of the North Basin on Multivariate Environmental Gradients

Cyprinidae

Longnose Dace

Rhinichthys cataractae (Valenciennes), the longnose dace, was collected by Woolman (1896) from the Pembina, Forest, Maple, Sheyenne, Buffalo, and Red Lake Rivers and Daugherty Creek, a tributary to Lake Traverse; at these sites it was often abundant in the samples (Figure A44). Hankinson (1928) found the longnose dace in the Red, Pembina, Park, and Sheyenne Rivers; and Wilson (1950) collected it from the Sheyenne River above Baldhill Creek. The longnose dace has been found in several streams in the basin. It has occurred at 16% of sites sampled since 1962 (Table 4). Where found, the species has usually been abundant in site collections, with 50 individuals in a sample not uncommon, and several hundred have been taken at sites on the Sheyenne, South Branch Wild Rice, and Clearwater Rivers in recent years. It has been found only once in the upper reaches of the Otter Tail River east of Fergus Falls, where the stream flows through many natural lakes.
