WFRV Local 5OSHKOSH, Wis. (WFRV) — The Wisconsin Department of Natural Resources (DNR) is ramping up monitoring efforts after confirming the presence of the invasive round goby in Lake Winnebago for the first time.
An angler first reported catching a round goby near the Bowen Street Fishing Pier in June. Since then, DNR crews have confirmed at least 10 additional round gobies from the same location.
“This is a small invasive fish that actually originates in the Black and Caspian Seas,” Patrick Siwula, an Aquatic and Invasive Species Biologist for the DNR, said. “They were first found in the Great Lakes outside Detroit in the late 1990s.”
The round goby has since spread throughout Lake Michigan and tributaries such as the Fox River, despite lock closures and dams designed to slow their movement. In
