Fisheries committee In evaluating and monitoring, again, I'll bring this back. It's very coordinated. It requires everyone to be involved because we can't be everywhere all the time. We're always looking for new technologies, things such as this environmental DNA where we can go out and sample the e

Fisheries committee Again, just to help you understand, yes, the American eel is listed provincially, but federally its status is still being clarified. The United States is again torn, because in eastern Lake Ontario, in the St. Lawrence River, the American eel population used to support a very sig

Fisheries committee Careful control is done in evaluating the treatment options for things such as the sea lamprey program. Right now, they're moving away from chemical treatments. In the past they relied on using a chemical called TFM, which was a piscicide: it killed things. Now they're moving tow

Dr. Tim Johnson
Fisheries committee Yes. Without getting into detail, there's not much I can really add, other than to say that I think your point is very important. We need to understand the biology. On the question that came up earlier about predicting the next species, if we don't understand the basic biology,

Dr. Tim Johnson
Fisheries committee Yes. Again, I think it's a very good question. As Anne pointed out, I think we've made tremendous progress with ballast water, such that it's maybe not at the top of the list. I certainly would be very fearful if we backed off in any way or were seen to slide backwards, because

Fisheries committee An example is sea lamprey. When you say “success” you're inferring that we were able to eradicate and remove it. Regrettably, that doesn't happen. Most of these organisms are highly successful, so instead we are able to control them. Through an annual investment of about $25 mi

Dr. Tim Johnson
Fisheries committee Certainly. Again, as Anne has pointed out, I don't really see it as a change in definition. It's simply a matter of clarity that when people think about something like a non-native species, if there was a moniker, people were thinking everything was harmful and then they were fin

Fisheries committee Anne, I think that's an excellent point, really, and I'll say, maybe to the chagrin of my minister at times, that I probably work more closely with U.S. and federal colleagues on many of the research programs on the Great Lakes than I do with other people in the inland jurisdicti
May 7th, 2012Committee meeting
Dr. Tim Johnson
Fisheries committee Thanks, Anne. Basically, I think ballast water was historically a very significant source for invasive species, aquatic invasive species especially, and certainly foreign species that arrived. But I think, as Anne pointed out in her talk, subsequent to 2006, we haven't seen, or
