| Abstract | Juvenile bluegills, Lepomis macrochirus (initial weight, 1.8-8.0 g), were individually marked and fed to excess during a 30-day constant temperature test; day length was 16 h. Fish were tested at temperature intervals of 2 degrees from 20 to 36C. The highest specific growth rate occurred at 30C (2.35%/day); however, growth rates of only the groups held at 20 and 36C were statistically different from the rate for the group held at 30C. |
