Abstract
In the absence of a predator, small bluegill (Lepomis macrochirus) had a mean upper avoidance temperature of 30.0 °C as compared with 29.8 °C for large bluegill. In the presence of a predator (Micropterus salmoides), bluegill upper avoidance temperatures were significantly higher; however, predator size did not influence this relationship. In the presence of a small and large bass, small bluegill had a mean upper avoidance temperature of 34.0 and 33.9 °C, respectively, while large bluegill had a mean upper avoidance temperature of 33.8 and 33.1 °C. The preferred temperatures of large bluegill [Formula: see text] were statistically higher than that of small bluegill [Formula: see text]. There was no significant difference in the preferred temperatures for bluegill from heated and normothermic sites.
