Evidence That Sea Lamprey Control Led to Recovery of the Burbot Population in Lake Erie
Abstract Between 1987 and 2003, the abundance of burbot Lota lota in eastern Lake Erie increased significantly, especially in Ontario waters. We considered four hypotheses to explain this increase: (1) reduced competition with lake trout Salvelinus namaycush , the other major coldwater piscivore in...
