DNR electrofishing boats troll the St. Joseph River during a drill this week in Berrien County.

Stefan Tucker made a head-turning discovery when doing research for his senior undergrad thesis in the St. Mary’s River. Instead of finding the sturgeon he was looking for he found wild Atlantic salmon. Previously, the species was believed not to be reproducing in the upper Great Lakes. Tucker explained to us just what this discovery means and what questions it has now raised about the salmon’s presence in the Great Lakes.
