The removal of gizzard shad (Dorosoma cepedianum) had a positive but short‐term effect on the largemouth bass (Micropterus salmoides) and bluegill (Lepomis macrochirus) populations in Chambers County Public Fishing Lake, Alabama. There was a favorable shift in community structure of the sport fishes 1 and 2 years after elimination of gizzard shad. The number of young‐of‐year largemouth bass and bluegill increased following gizzard shad removal and the survival of young largemouth bass increased considerably. Young‐of‐year largemouth bass and bluegills subsequently declined 2 to 3 years after gizzard shad removal to levels encountered when gizzard shad were present, indicating that species of fish other than gizzard shad may be effective in competing with largemouth bass and bluegill.
