Yes, I would say the club tunicate is one of hundreds of species Mr. Thompson already mentioned, and we did go to P.E.I. to have a look at that particular case. Our observations and recommendations are at a more global level, because there are, as I said, hundreds of these things. The green crab's another one, and we're all aware of zebra mussels. Each one of those species causes economic as well as social harm in the communities where they exist.
But we point to the Department of Fisheries and Oceans to tell us what precisely the risk is and what the response should be to that issue in terms of control and eradication at this point. I think we know from what we read in the background material, but once these organisms are established, it's very difficult, if not impossible, to eradicate them.
So the whole focus needs to be on prevention. Once they're here, it's a management issue. How do you control them, how do you minimize their negative impacts?
