What to know about Scientific Research

Researchers from the University of Illinois, the Mille Lacs Band of Ojibwe, and the Great Lakes Indian Fish and Wildlife Commission identified six walleye spawning hotspots in Mille Lacs Lake. The study found that 96% of walleye exhibit site fidelity, suggesting that protecting specific undeveloped shoreline habitats is critical for the species' recovery.
