Abstract

In 1992, the U.S. Fish and Wildlife Service began research on the life history, population dynamics, and stock delineation of siscowet lake trout, Salvelinus namaycush siscowet, in Lake Superior. Siscowet were captured with gill nets in 80-150 m of water on 23-26 April 1992 north of the Apostle Islands in western Lake Superior. Of 91 captured siscowets, one male had fully developed testes in nearly ripe condition and one female had eggs running from the vent. This observation represents the earliest dates that lake trout of any morphotype have been found in spawning or near-spawning condition.
