Case Histories of Three Walleye Stocking Techniques with Cost-to-Benefit Considerations

Cost:benefit of 3 walleye fisheries were evaluated in 3 Texas reservoirs. Costs to establish walleye fisheries included expenses for equipment and for labor to procure and hatch eggs, to rear fry or fingerlings, and to stock reservoirs. Benefits of walleye fisheries were determined by multiplying the monetary value of a man-hour of recreational fishing by number of manhours of walleye fishing as determined by creel surveys. At Meredith Reservoir, where low densities of fry were stocked as the lake initially filled, costto- benefit of 1:89 was achieved in 3 years. At Greenbelt Reservoir, where fingerlings were stocked at low densities into an established fish community, it took 7 years to achieve a cost-to-benefit of only I :21. At White River, a reservoir which also had an established fish community, mass stocking (introducing large numbers of frys) achieved a cost-to-benefit of 1:42 in only 2 years. The technique of mass fry stocking is recommended for Texas waters because in this study it resulted in establishing a walleye fishery more quickly and more cost effectively than fingerling stockings, particularly in reservoirs with established fish communities and those where limited walleye reproduction is expected.
