DescriptionThis specimen (15.2 cm or 6 inches in length) was caught in 1993 in Lake St. Clair by M. Bisson. He brought the live fish to the Ministry of Natural Resources in Wheatley, Ontario. It was kept alive for six months and thought to be an odd-looking Mottled Sculpin. When the fish died, it was sent to the ROM and identified as a Round Goby, an alien species thought to have arrived in North America from Europe in the ballasts of ocean-going ships. The Round Goby was first discovered in 1990 in the St. Clair River, and has since spread to all the Great Lakes. This aggressive fish, which is less than 25 cm in length, threatens to reduce populations of native bottom-dwelling species such as sculpins and darters. Anglers can help to stop the spread of this destructive intruder by removing it from the water and contacting Invading Species Hotline of the Ontario Federation of Anglers and Hunters at 1-800-563-7711.
