Spring, summer and fall lake trout surveys are conducted throughout Keweenaw Bay and western Lake Superior following protocols established by GLIFWC and the Lake Superior Technical Committee. These survey efforts are shared and compared with agencies and datasets across the Lake Superior Basin as a means of gauging lake trout abundance and health on a broad spatial scale, and are critical in providing fisheries data from the Keweenaw Bay region. Fish are measured, weighed, assessed for sea lamprey attacks, disease, overall condition/ health, tags and fin clips (indicating hatchery fish), etc. 

Ultimately, the goal of Keweenaw Bay’s tribal hatchery is to rear native fish (lake and brook trout and walleye) for stocking into Lake Superior and adjacent streams to provide a self-sustaining fishery on the reservation and 1842 ceded waters. Our current production goal is 50,000 lake trout yearlings (6″ fish), 40,000 brook trout yearlings, 30,000 coaster brook trout and 50,000 walleye fry annually.
