Year Class Contribution of Genetically-marked Florida x Northern Largemouth Bass Stocked in Three Texas Reservoirs

Percent year class contribution was evaluated for genetically-marked Florida largemouth bass (Micropterus salmoides floridanus) x northern largemouth bass (A/. 5. salmoides) stocked in 3 Texas reservoirs. Electrofishing catch rate and size structure data were used to determine population characteristics of each study reservoir. Stocking rates of genetically-marked fingerlings ranged from 30 to 200 fish/ha. Post-stocking collections were made by electrofishing at permanent stations over a 4-year period. Town Reservoir, which had the highest largemouth densities and recruitment, had the...
