The Great Lakes Fishery Commission was established in 1955 by the Canadian/U.S. Convention on Great Lakes Fisheries. The commission coordinates fisheries research, controls the invasive sea lamprey, and facilitates cooperative fishery management among the state, provincial, tribal, and federal management agencies.

Fishing, boating, scuba diving, and other recreational activities can spread aquatic nuisance species to new lakes, rivers, and streams. Nuisance species include zebra mussels, round gobies, spiny water fleas, whirling disease, rusty crayfish, Japanese shore crabs, sea lamprey, carp, ruffe, hydrilla, purple loosestrife, Asian clams, and other harmful aquatic plants or aquatic animals.

The Great Lakes Information Network (GLIN) is a partnership that provides one place online for people to find information relating to the binational Great Lakes-St. Lawrence region of North America. GLIN offers a wealth of data and information about the region's environment, economy, tourism, education and demographics.
