Anglers key to stopping round gobies

The Ministry of Natural Resources reminds anglers and the baitfish industry it is illegal to use the round goby as bait in Ontario waters because of the significant negative impact they have.
Gobies are voracious eaters of young fish and reproduce often, which can lead to a sharp drop in the number of native species in a lake.
Round gobies are now found in all five Great Lakes as well as two inland locations—one below the lock at Hastings on the Trent Severn Waterway near Peterborough and the other in the Pefferlaw River south of Highway 48 near Sutton.
The MNR and Ontario Federation of Anglers and Hunters, partners in the Invading Species Awareness program, are working with other partners to monitor goby populations at both those locations.
The goal is to stop the goby spread to the Kawartha Lakes and Lake Simcoe.
In southern Ontario, there already are high numbers of gobies in Lake St. Clair, Lake Erie, and much of Lake Ontario, where they already are having negative impacts on fish populations.
The MNR is expanding its enforcement efforts in southern Ontario to try to educate anglers and further stop the spread of this invasive species.
If you believe you have found round gobies or any other invading species in a new location in Ontario, call the Invading Species Hotline at 1-800-563-7711 or visit
The public is encouraged to help protect Ontario’s natural resources by reporting violations to their local MNR office or anonymously to Crime Stoppers at 1-800-222-TIPS (8477).
