Evaluation of Walleye Introductions into Lake Burton and Seed
Project number: F-25
To establish and maintain a walleye population and fishery by stocking and to document any measurable impact of these introductions on both forage and game species. To compare the effects of stocking on forage abundance at two different population densities of yellow perch.
Over 12 million walleye fry were introduced into Lake Burton in 1990 and 1991 to supplement limited natural reproduction in the existing low density population. One million walleye fry and 41,373 walleye fingerlings, ranging from 50 mm to 179 mm total length (TL), were introduced into Lake Seed from 1990 to 1995 in order to establish a walleye population and fishery. Fry stockings were not successful in Lake Burton. Limiting factors implicated in this unsuccessful effort included high latent mortality immediately after stocking due to poor water quality in the hauling media, insufficient food availability shortly after stocking, and predation. Walleye introductions were moderately successful in Lake Seed. Survival from all fry and fingerling stockings was documented in fall gill net samples. The primary factor which hindered stocking success in Lake Seed was two dramatic flood events in 1994 and 1995, which displaced significant numbers of stocked walleye into the neighboring downstream reservoir (Lake Rabun). As a result, a moderate-density walleye population and minor fishery was subsequently established in Lake Rabun.
