Round Goby
The round goby is currently angering anglers in Lake Michigan and the Bay of Green Bay. Anyone who has tried to ice fish in areas where there are round gobies knows what nasty, bait stealing fish they are.
The round goby is a bottom dwelling fish with a large head and can grow to be 10 inches. Round gobies are thriving in the Lake Michigan because they are aggressive, voracious feeders and can forage in total darkness. The round goby takes over prime spawning sites traditionally used by native species, competing with native fish for habitat and changing the balance of the ecosystem.
If you catch a round goby, DO NOT THROW IT BACK ALIVE.
