MSU researcher leads innovative effort to protect lake whitefish using genetic markers

Jared Homola, an assistant professor in the MSU Department of Fisheries and Wildlife, is using advanced genetic modeling to help conserve Lake Michigan’s declining lake whitefish population and improve fishery management strategies.

Earlier this year, Jason Smith, a fisheries biologist with the Bay Mills Indian Community in Michigan’s Upper Peninsula, spoke with Interlochen Public Radio about an ominous trend threatening one of the Great Lakes’ most foundational and key fish species: lake whitefish.

“Even if we bring (commercial fishing) harvest to zero, the lakes are still headed toward extirpation,” Smith told IPR in January about the species.

Lake whitefish make up 89% of fish caught in the Great Lakes among Michigan-licensed anglers and 95% of sales for all Great Lakes fish, according to Michigan Sea Grant’s 2020 Status of Michigan Commercial Fisheries. They’re also culturally important and valuable for many fishers licensed by tribal nations around the Great Lakes.
