I think the threat from these Asian carp that they have known about for years and that shipping canal in Chicago and the slow response from both sides of the border is "a day late & a dollar short ". It's just a matter of time and our fisheries as we know them now won't exist .... Not good that's for sure

Do grass carp explode in numbers like those asian carp?

 

No , that is the Silver Carp. Grass Carp eat vegetation , the ones that really screw things up are the filter feeders like the Silver and Bighead Carp that eat plankton, the same thing the fry of our gamefish eat. There have been a few grass carp caught over the last few years, think there was actually sterile ones for sale at one time for vegetation control.

So these grass carp arent much an issue?

 

That remains to be seen. If they are not sterile and their population grows, they may eat large amounts of vegetation and negatively affect the fisheries.

The Erie grass carp was sterile. I don't recall reading whether or not the five caught in Toronto were sterile or not.

You can still legally buy Grass Carp for weed control in Canada, just not in Ontario. The various gov'ts need to get their crap together.
