All sturgeon caught in the Detroit River must be released. Over-harvesting and habitat loss from dam construction are known reasons for the fish’s decline.Īnglers can keep one sturgeon per year, but only if the fish is a certain size and is caught in a few state waters. Lake sturgeon, a threatened species in Michigan and 18 other states, according to the Fish and Wildlife Service, are freshwater fish that are known to inhabit the bottoms of lakes, river basins and drainages including the Hudson Bay, the Great Lakes and the Mississippi River. “Imagine everything that fish has lived through and seen.” “She was tired out and didn’t fight us very much,” Wigren said.

The agency said it quickly released the fish back into the river after it was weighed and measured.
