18. Lake trout restoration For over 40 years the GLSC has worked closely with the Great Lakes Fishery Commission and its cooperating U.S. and Canadian Federal agencies, the eight Great Lakes states, the Province of Ontario, and Tribal fishery management agencies to restore lake trout populations in all of the Great Lakes.For over 40 years the GLSC has worked closely with the Great Lakes Fishery Commission and its cooperating U.S. and Canadian Federal agencies, the eight Great Lakes states, the Province of Ontario, and Tribal fishery management agencies to restore lake trout populations in all of the Great Lakes.
