Three More Invasive Asian Grass Carp Found in Toronto, Totalling Five

CBC

Five invasive Asian grass carp have been found in Toronto to date. The ecological impact is yet unknown.

Earlier this week, officers with the Toronto and Region Conservation (TRCA) caught three Asian grass carp in the waters around the Toronto Islands Marina off Lake Ontario, bringing the total now to five.

The latter two were discovered in July in Tommy Thompson Park. Carp are not native to Ontario and the TRCA have no idea how the fish got into the province.


Grass carp feed extensively on aquatic vegetation, often uprooting large areas of vegetation, thus depleting other native fish populations.

The largest fish caught so far was a 36-pound specimen. All fish have been sent to a Fisheries and Oceans Canada laboratory in Burlington for further testing.

If you spot an Asian carp, you are asked to call the Invading Species hotline at 1-800-563-7711.
