Experiments were conducted to determine the effect of aquarium volume and feeding regimen on growth in length and weight and on food conversion efficiency by bluegill fed rations of mealworms. Two 30 day periods were utilized for each study. Part one, which examined the effect of aquarium volume on growth extended from January 20 to February 18 and from March 27 to April 25, 1972. Part two, which examined the effect of multiple feedings compared with single feedings on growth, ran from May 30 to June 28 and from July 1 to July 30, 1972. The studies were conducted in a controlled environment aquarium. Food consumption, growth and food conversion by individual fish in each experiment were monitored closely. All conditions with the exception of the testable variable were held as constant as possible. Water quality was monitored and judged to be within acceptable limits for fish culture.Aquarium volumes of 5, 10 and 15 liters did not affect growth in length and weight or food conversion efficiency of individually held bluegill.A 30 day daily regimen of one feeding compared with three feedings of a constant ration of mealworms resulted in significantly greater length, weight and conversion efficiency for multiple-fed male bluegill. After 60 days length and weight were not significantly different but conversion efficiency was significantly greater for multiple-fed male bluegill.
