Abstract Increased feeding frequency has been used in aquaculture to increase growth and food conversion efficiency, and recent laboratory studies have indicated that feeding frequency could be used to reduce the size variation within groups of hybrid bluegills (F 1 : Male bluegill Lepomis macrochirus × female green sunfish L. cyanellus ). Our experiment evaluated the growth of pond‐reared hybrid bluegills fed equal amounts of food either once or four times per day. We were particularly interested in reducing the size variation and increasing the percentage of harvestable‐size fish (≥110 g). After 194 d, there was no significant effect of feeding frequency on growth, food conversion efficiency, size variation, or percentage of harvestable‐size fish.
