Red Snapper & Largemouth Bass Fish Tag-Recapture Study
Red snapper fish are being tagged as part of a collaborative study being conducted by Auburn University, the Dauphin Island Sea Lab and the University of South Alabama, and funded by the Alabama Department of Conservation and Natural Resources Marine Resources Division to examine recreational fisheries management in the northern Gulf of Mexico.
Largemouth bass fish are also being tagged at several lakes in northern Alabama.

EVALUATING THE INFLUENCE OF THREADFIN SHAD ON LARGEMOUTH BASS & BLUEGILL POPULATIONS IN SMALL IMPOUNDMENTS
The two-species fish community consisting of largemouth bass (Micropterus salmoides) and bluegill (Lepomis machrochirus), which was popularized via research by Homer Swingle and others at Auburn University, has provided the foundation for small impoundment fish stocking and management efforts since the mid-1900s. This species combination is commonly enhanced with additional prey species to provide alternative forage for largemouth bass with the goal of increasing growth and condition of these predators. Threadfin shad (Dorosoma petenense), a native fish of the herring (Clupeidae) family, are often added to small impoundments as a forage enhancement. Threadfin shad potentially provide an energy-rich food source for largemouth bass because they attain a relatively small adult body size and are therefore vulnerable to predation by a wide range of sizes of largemouth bass. However, threadfin shad may compete with juvenile bluegill for zooplankton, which could reduce bluegill growth, survival and condition. Investigations of threadfin shad introductions on largemouth bass and bluegill populations have been mixed, with some indication for negative effects on bluegill and positive effects on largemouth bass growth. Many of these studies have been conducted in large lakes and reservoirs. Surprisingly little work has addressed the influence of threadfin shad on fish communities in small impoundments. Our study combines an experimental stocking of threadfin shad in ponds at Auburn University’s E.W. Shell Fisheries Experiment Station with a survey of privately-owned established ponds. We are assessing differences in largemouth bass and bluegill growth, condition, and food habits between ponds with and without threadfin shad. We will also assess differences in zooplankton communities and temporal patterns of larval fish occurrence to assess potential mechanisms for interactions between threadfin shad, largemouth bass and bluegill. The findings of this research will have important implications for small impoundment management in the southeastern US and beyond.
