When stocked at high densities in ponds and fed Purina Trout Chow, F 1 hybrids of male redear (Lepomis microlophus) X female green sunfish (L. cyanellus) used supplemental food poorly and growth was unsatisfactory. F 1 hybrids of male green sunfish X female bluegill (L. macrochirus) utilized supplemental food readily and produced populations that had high percentages of catchable fish at the end of the first year of feeding. Males of the latter hybrid grew at a significantly higher rate than did the females. Conversion values were comparable to those obtained in feeding channel catfish.
