The Catch: Whitefish recruitment

The Catch: Whitefish recruitment
August 8, 2022 GLN Editor

Broadcasting in our monthly PBS television program, The Catch is a Great Lakes Now series that brings you more news about the lakes you love. Go beyond the headlines with reporters from around the region who cover the lakes and drinking water issues. Find all the work HERE.

This month, The Catch features a look at how scientists are studying how well whitefish are surviving to adulthood in the Great Lakes.

Kurt Williams of Great Lakes Echo explains why lake whitefish, a native species in the Great Lakes, is experiencing what is known in the world of fisheries biology as a “recruitment problem.” This recruitment issue means that fewer young whitefish are making it to adulthood. Williams explains that the likely culprits are invasive species like zebra and quagga mussels.

When it comes to combating invasive mussels, Williams said from his view, there’s not much that can be done.

“I have seen stories about efforts to control them, but really I think that horse left the barn. There are hundreds and trillions,” he said. “They dominate the ecosystem.”

    I’m a Michigan girl [Deckerville in Sanilac county & Saginaw] living in Tennessee since 1979. Foolish move. I still miss Michigan, Tennessee is not the same. One thing I miss a lot is Friday night fish-fry dinners at local establishments along Lakeshore Road such as those in Forester . Great Lake’s Whitefish has always been my favorite; Mom and Dad favored Perch. Naw….Whitefish! I am distressed hearing about the Zebra mussel (I take it they are not edible) and wish there was something I could do.
