If you've gone fishing you've heard about them before - Asian Carp.
The province is trying to prevent the spread of invasive species like the fish, which is threatening to come into Ontario via the northern end of the Mississippi River.
Minister of Natural Resources David Orazietti says the province stopped 39,000 lbs of Asian Carp at the border.
The fish has been known to overcrowd lakes and eat the food supply of native fish.
The province is planning to introduce legislation that would be able to help officials deal with invasive species like this by ways of regulation and fines. While Orazietti says there are a list of rules out there already, it doesn't give the province enough power to deal with this issue.
