Round Goby.
 Engbretson, Eric, U.S. Fish and Wildlife Service

According to the Ohio Department of Natural Resource’s Ohio Field Guide to Aquatic Invasive Species, the Round Goby is a small bottom-dwelling fish with “very distinctive frog-like raised eyes.”

According to the United States Federal Aquatic Nuisance Task Force, control methods include electrical barrier use and the use of “ piscicides.”

It is illegal to “transport this species from Lake Erie under any circumstances,” according to the ODNR Division of Wildlife.

The Round Goby, says the ODNR Field Guide, is currently “thriving.” This fish eats the eggs of other fish, and competes against native species for food and living and spawning spaces.
