Preferred temperatures were determined in a laboratory temperature gradient for the common shiner Notropis cornutus (Mitchill). Preferred temperature was correlated with age, size, season, and nutritional state. Preferred temperatures were higher than, and positively related to acclimation temperatures in all groups. Age, size, and starvation did not significantly affect the preferred temperature. Significant seasonal differences in preferred temperature were observed with springcollected fish preferring higher temperatures than autumn-collected fish kept at the same ambient water temperature.
