Texas Parks and Wildlife Department stocks Toledo Bend Reservoir annually with fingerling Florida largemouth bass (Micropterus salmoides floridanus). Studies suggest that largemouth bass stockings often result in variable and low contributions to cohort abundance. We explored effects of aquatic vegetation on stocking success of fingerling Florida largemouth bass marked with a pelvic fin clip in three species of aquatic vegetation (hydrilla Hydrilla verticillata, coontail Ceratophyllum demersum, and Eurasian watermilfoil Myriophyllum spicatum) in Toledo Bend Reservoir.

Electrofishing the littoral zone of Lucchetti Reservoir, Puerto Rico, from 1992 through 1997 indicated dynamic changes in fish community structure, despite consistent annual water level regimes. Nine species of fish, including 2 cichlids, 2 centrarchids, and 2 ictalurids, were collected. Relative abundance varied significantly over seasons and years for most species. One species, the bigmouth sleeper (Gobiomorus dormitor), may have become extirpated during the period and 1 new species, armored catfish (Liposarcus multiradiatus), became established. Adult largemouth bass (Micropterus...
