Growth, Survival, and Reproduction by Bluegill X Green F1 Hybrid Sunfish and Largemouth Bass Stocked in Three Small Lakes
Percy W. Laarman
Abstract.-Growth, survival, and reproduction were determined for male bluegill X female green sunfish F1 hybrids and largemouth bass stocked in three small lakes closed to public fishing. After 4.5 years in the lakes, growth and survival rates were satisfactory for the hybrids. Reproduction by F1 hybrids was extremely limited. Growth of largemouth bass was slower than the statewide average and survival of stocked bass was low. Reproduction of largemouth bass was evident, although survival of the progeny was low.
