I'm not sure if Transport would be the appropriate group.
DFO has hired a number of research scientists over the past decade explicitly to work on invasive species issues. Now I wouldn't say that it's their sole responsibility to go out and count samples like this, but very clearly if we had a national program, they could oversee the counting. Often what they're going to do is send it out to a company to do the actual counting and identification, but you would then have these scientists interpret that data to see whether or not there are new problems over time.
I would love to see that happen. I'd made a call for it years ago. I think it should be done. Invasive species are one of the odd issues that the more trade you have, the greater your exposure is to invaders. All of us want to see our economy grow, and because of that, our exposure to these invaders—primarily through shipping but also through airplanes—is going to increase in the future.
I think it would be smart to set up programs where you can try to.... What we do is we study the vectors of the so-called pathways that transmit those species. You're not going to be able to control all of those pathways, but if you focus on the major ones such as ballast water in ships, then you can try to figure out how you can mess up that vector so that it can't transmit the species, without interfering with the trade.
