If I can add to that, we have done some studies, and the Great Lakes Fishery Commission, with whom we work, doing the sea lamprey program...they have funding for research on some of these things to look at impacts on other species. The studies to date have shown very limited impacts. There are certain times of the year when some species might be more susceptible. When we're planning the activities, we'll try not to be doing the lampricide treatments at a time when a species might be sensitive, when a species is spawning. So we make every effort to make sure it isn't a time when they're sensitive. Also during the work, it's very carefully done, tracking what the concentration of lampricide is in the waterway to make sure it only gets to the level that's needed to eradicate the lamprey and doesn't get higher, where it might be a risk for other species.
