Project Details
Throughout the Great Lakes Basin, remnant stocks of lake sturgeon exist at low abundance. Traditional fish sampling and assessment methods are marginally effective for these populations and can lead to fish mortality. Lake sturgeon congregate each spring when they spawn in large rivers. Nonlethal hydroacoustic technology, successfully used to count salmon in Pacific Northwest river systems, was used to evaluate the lake sturgeon population in the Sturgeon River, Michigan, and then applied to evaluation of the Muskegon River population.
