Scientists are still trying to figure out how a changing climate affects walleye and other species of fish. Most don’t expect the walleye to be a winner. As global climate change continues delivering warmer temperatures and heavier rains to Minnesota, lakes and their inhabitants will feel it. “One of the places you expect climate change to make a big difference is in changing the mix of species that do best in a lake,” said John Magnuson, director emeritus of the Center for Limnology — the study of inland waters — at the University of Wisconsin-Madison.
