Lake Sturgeon Movement in Saint Croix River (WIDNRBASC)

Lake sturgeon are highly migratory and are currently managed as separate populations within tributaries of the Upper Mississippi River. Little is known regarding seasonal movements, habitat use and population connectivity within the UMR, especially within the Wisconsin tributaries. Therefore, adult lake sturgeon were tagged with acoustic transmitter tags within the Chippewa, St. Croix and Black rivers in Wisconsin and a receiver network was installed within each river system to track movements of fish. Specifically, within the St. Croix River, a total of 30 adult lake sturgeon were tagged in 2021-2023 and 3 receivers were installed throughout the Lower St. Croix River from St. Croix Falls to Prescott, WI.
