Round Goby invade Great Lakes

Canadian scientists uncover alarming invasion of round goby into Great Lakes tributaries: impact on endangered fishes likely to be serious

A team of scientists from the University of Toronto, the Ontario Ministry of Natural Resources and the University of Guelph has identified a drastic invasion of round goby into many Great Lakes tributaries, including several areas of the Thames, Sydenham, Ausable and Grand Rivers. A number of the affected areas are known as "species-at-risk" hot spots.

"This invasion poses many potential threats for native species of fish and mussels," says Mark Poos, a PhD Candidate in U of T's Department of Ecology and Evolutionary Biology. Poos is lead author of the study published recently in the international journal Biological Invasions. Up to 89 per cent of fish species and 17 per cent of mussel species are either known or suspected to be affected by the goby invasion. Of particular concern is the impact on species that have a conservation designation, including such endangered species as the small eastern sand darter fish and mussels such as the wavy rayed lampmussel.

The Great Lakes and its tributaries are Canada's most diverse aquatic ecosystems, but are also the most fragile, notes Poos. Several of these rivers hold species found nowhere else in Canada, including 11 endangered species and two threatened species. Furthermore, the round goby, an aggressive ground-feeder, is a threat to three globally rare species: the rayed bean, northern riffleshell and snuffbox mussels.
