New River shiners Notropis scabriceps (Cope) from the East Fork of Greenbrier River, West Virginia were acclimated to temperatures of 6, 12, 18, 24, 30, and 33 C and exposed to a 16–18 C horizontal gradient. Fish preferred temperatures higher than their acclimation temperatures of 6, 12, or 18 C, but lower than their acclimation temperatures of 24, 30, or 33 C. Preferred (P) and acclimation (A) temperatures were related by P = 1.12A −0.018A 2 + 4.28. The final preferendum was calculated to be 19.3 C.
