A statistical analysis of new and published laboratory data revealed strong geographic similarities in acute (up to 4‐hour) temperature preferences for several freshwater fishes. Regression models developed from our laboratory studies predicted acute temperature preferences of species from other geographic areas. Species within a family (three cyprinids, two ictalurids, and six centrarchids were tested) have similar acute preferenda, except that white crappie (Pomoxis annularis) differs from other centrarchids. For the species analyzed, acclimation temperature is the only significant variable affecting acute preferenda and accounted for up to 82% of the total variation. These emerging generalities should minimize the need for further site‐specific studies of acute temperature preference for individual species and thus should result in substantial savings in money and time.
