Lake trout Salvelinus namaycush historically were the keystone predator and supported a valuable commercial fishery in the Laurentian Great Lakes until the extirpation of most populations by the 1950s. Lake trout have been stocked throughout the Great Lakes since the 1970s, but aside from local progress in restoration in Lake Huron, rehabilitation has occurred only in Lake Superior. Recently, ecosystem changes in Lake Huron have resulted in the lakewide recruitment of wild adult lake trout. The USGS GLSC works cooperatively with a variety of agencies (MDNR, OMNR, CORA, USFWS) to conduct long-term gill net surveys to assess the population status of lake trout in Lake Huron. Assessment of long-lived fish such as lake trout can only be achieved through long-term population surveys.
