Taxonomic CommentsApparently introgressed in past with N. micropogon in Monongahela drainage (Lee et al. 1980). Regarded as a subspecies of N. micropogon by Page and Burr (1991), retained as a full species by Mayden et al. (1992) and in the 1991 AFS checklist (Robins et al. 1991). Morphological and reproductive-behavioral data indicate that the genus Nocomis is monophyletic (Maurakis et al. 1991).

Ecology & Habitat
Habitat
Medium- to large-sized tributaries of main channel New River, with moderate gradient, warm, usually clear water, and gravel to boulder substrates. In swift water and pools. In West Virginia: in late summer, only in riffles and adjacent runs; avoids shallowest depths; stays near substrate (Lobb and Orth 1988). Spawns over gravel mound nest made by male. In West Virginia, constructs spawning mounds in areas of small to large gravel, shallow water (0.15-0.75 m), and moderate water velocity (0.05-0.69 m/sec) (Lobb and Orth 1988).
Reproduction
Gravel mound nests made in May and June.
