Distribution of Fishes in the Red River of the North Basin on Multivariate Environmental Gradients
Cyprinidae
Hornyhead Chub
Nocomis biguttatus (Kirtland), the hornyhead chub, was listed as Hybopsis kentuckiensis by Woolman (1896), who collected specimens from the Forest, Maple, Sheyenne, Otter Tail, Buffalo, and Red Lake Rivers (Figure A25). The species was also reported by Olson (1932), who collected 16 specimens from the Red Lake River near Crookston and 1 specimen each from the Lost (Clearwater River) and Wild Rice Rivers in Minnesota. The hornyhead chub has been taken primarily from eastern basin tributaries, except for collections made in the Forest River, where as many as 478 individuals were collected at a single site in 1994. The hornyhead chub has evidently been extirpated from the Sheyenne River. The species has been found at 47% of stream sites in the NCH and 35% of the sites in the NLF ecoregions since 1962 (Table 4). It has not been found in the reaches of the northern RRV or NMW ecoregions.
