A changing climate could bring one piece of good news for walleye fishermen. 

A study out of the University of Wisconsin-Madison says increasing temperatures in Lake Superior will expand habitat for fish that thrive in slightly warmer water, like walleye, Chinook salmon and lean lake trout.  Researcher Jim Kitchell says that means populations of certain fish in Lake Superior could increase in coming years.
