As water temperatures go up, fish numbers are poised to go down -- at least certain types of fish in certain Minnesota lakes.
A new report by the National Wildlife Federation takes a closer look at how freshwater fish might be affected by climate change. Here in Minnesota the biggest threat may be to the cisco, a small fish that's a primary source of food for walleye and northern pike. The Associated Press reports a DNR expert doubts ciscoes will survive warmer temperatures in Mille Lacs or a majority of the other Minnesota lakes where they now live.
Trout streams could also suffer, according to the federation's report.
Some of the business owners who suffered from a dearth of tourist traffic this summer contend the stricter limits are what kept anglers away.
