Abstract

1. 1.|A 1°C increase in constant acclimation temperature over a range of 6.5 to 33.1°C increased the critical thermal maximum (CTM) by 0.47°C for both starved and satiated hybrid bass; however, the CTM of starved fish averaged 0.35°C lower than satiated fish. 2. 2.|If the mean daily temperature was at least 24°C, diel oscillating temperatures of ±4°C amplitude increased the CTM. 3. 3.|With a mean daily temperature of 20°C, oscillating temperatures had no effect on the CTM for satiated fish and the CTM for starved fish was reduced. 4. 4.|Photoperiod had no discernible effect on CTM.
