Growth experiments were conducted with bluegill, Lepomis macrochirus, for 102 days under three different photoperiods at 26 C. One daily photoperiod increased from 15.5 to 19.8 hours, another decreased from 15.5 to 12.3 hours, and a third was held constant at 15.5 hours. Growth, food consumption (mealworms, Tenebrio molitor), and food conversion efficiency were evaluated for bluegill under each set of conditions.Under the conditions used in this experiment there was no apparent effect of photoperiod on the growth of bluegill. This was true for all measurements of growth, food consumption, and food conversion efficiency. It was also true when males and females were compared for each of these measurements.
