Abstract

Returns from mature lake trout (Salvelinus namaycush) tagged in western Lake Superior in 1959 and 1962-65 described here suggest that trout disperse widely from the spawning grounds after spawning and return in subsequent years. Although the data were not extensive, returns from lake trout tagged near Keweenaw Point in 1950 and off Marquette, Michigan, in 1952 suggested similar movement. Loftus stated that river-spawning lake trout of eastern Lake Superior returned annually to the same spawning streams. Movements of lake trout must be understood to manage and evaluate the rehabilitation of lake trout stocks in Lake Superior, especially when the trout move across interstate and international boundaries and are subject to different fishing regulations and fishing pressures.
