GREEN BAY, Wis. (AP) — A Milwaukee-based researcher is trying to re-establish the historically plentiful amount of mayflies in the bay of Green Bay. Jerry Kaster of the University of Wisconsin-Milwaukee says the flies have played a crucial role in the health of the bay and have served as a major protein source for walleye and other fish. He says that restoring the insects could cause the bay to once again become a world-class fishery and boost the local economy. Although the lower portion of the bay hasn’t seen an overwhelming number of mayflies in decades due to poor water quality, Kaster believes conditions have improved enough to support a repopulation. For the past few years Kaster and student volunteers have been collecting mayfly eggs and placing them in the bay.
