In the early 1990's, about 200,000 fingerling striped bass were stocked in West Point Lake, Georgia to establish a put-and-take fishery. These fish were stocked at lower-than-normal densities because of the predation threat they pose to the trout fishery in the upper Chattahoochee River. This study was conducted to assess that threat and to make recommendations to Georgia Department of Natural Resources regarding the striped bass and trout stocking programs. Our objectives were to estimate the number of striped bass in the trout waters (via a mark and recapture study) and to determine their food habits. Sixty-two striped bass (range = 534-1066 mm total length) were sampled with a boat-mounted electrofisher and marked with Floy tags. Five fish were recaptured later. Over half the 67 stomachs examined were empty, and the remaining stomachs contained a variety of prey including crayfish, shad, and trout. Crayfish and shad were the most abundant prey; trout were among the least abundant and were in 8% of the stomachs that contained prey. Striped bass predation on trout in the upper Chattahoochee River has been confirmed, but the potential effect(s) to the trout fishery are unknown. These results are preliminary, and data analysis are on going.
