Natural History Wanderings

WPR reported

The Wisconsin Department of Natural Resources is increasing monitoring in Lake Winnebago for invasive round gobies that can force out native bottom-dwelling fish.

In June, an angler caught a round goby in Lake Winnebago at the Bowen Street Fishing Pier in Oshkosh, the first known detection there. The invasive fish is about 3 to 6 inches long with bulging frog-like eyes and a fused fin on their bottom side that looks like a suction cup. They can outcompete bottom-dwelling fish and they’ve been known to gobble up eggs of walleye and bass.
