Evaluation of Walleye Fingerling Stocking in Three West-Central Minnesota Lakes

摘要

Three years of high density walleye fingerling stocking from 1986 through 1988 intwo west central Minnesota lakes, Mary and Ida, yielded mixed results in improving the walleye fisheries. Lake Miltona was stocked at normal densities as a reference lake during the same years. Walleye from each stocking survived and appeared in the angler's catch from 1989 through 1991. Naturally hatched walleye of the 1986-1988 cohorts also appeared in the angler's catch. One of the six high density stockings established a strong year class that improved walleye fishing for two years in one lake.
