Abstract Seasonal depth distribution of landlocked alewives, Alosa pseudoharengus (Wilson), was determined in a shallow eutrophic lake. In spring they were concentrated in the deepest and coldest water, or less commonly near the warmer surface waters. During summer, alewives were evenly distributed above the anoxic hypolimnion. Their fall and winter actions were pelagic being characterized by avoidance of both surface and bottom waters.
