SOUTH HAVEN, MI – From the sunny beaches here this weekend, it appears the harsh winter of 2013-2014 is well behind us.

But the winter is expected to take a heavy toll on the alewife population of Lake Michigan in coming weeks, a Michigan State University Extension educator said.

No need to panic. Even with the large die-off that’s expected, there won’t be the massive mountains of fish washing ashore from Benton Harbor to Chicago that occurred in 1967, said Dan O’Keefe, a scientist with Extension’s Great Lakes Fisheries Education and Management. There are far fewer alewives in Lake Michigan now than there were then, he said.
