Abstract Bioassay experiments were conducted to determine thermal tolerance of early life history stages of bluegill sunfish. Bluegill eggs hatched at temperatures from 18 to 36C during two incubation tests. Maximal hatch occurred at 22.2 and 23.9C. Lower TL50 temperature for hatch or normal fry was 21.9C and upper TL50 temperature was 33.8C. Juvenile bluegills acclimated to 12.1C had a lower 96-hour TL50 of 3.2C and an upper 96-hour TL50 of 27.5C. Juveniles acclimated to 32.9C has a lower 96-hour TL50 of 15.3C and an upper 96-hour TL50 of 37.3C. TL50 increased with increasing temperature of acclimation. For juveniles acclimated to a given temperature, upper TL50 decreased with longer exposure. A preliminary test determined ranges of thermal tolerance for sac-fry and swim-up fry. In another preliminary test, juvenile bluegills were acclimated to 12.1, 19.0, 26.0 or 32.9C, and reared at a series of test temperatures for three to six wks. to define optimal temperature ranges for growth and survival.
