Of invasive species, okay. I know others may have different views on this. On sea lamprey, if I understand your question correctly, we have a lot of evidence that, if you cut back on control of sea lamprey, they shoot up in population extremely quickly. There's a strong correlation between increases in the population and impacts on fisheries. Unfortunately, we found that out the hard way. So the war on sea lamprey is really critical, and unfortunately it's ongoing, so that's critical.
Asian carp is obviously one that is very significant right now. Ninety per cent of the biomass in the Mississippi basin right now is Asian carp. They have simply taken over, so to think of that kind of thing happening in the Great Lakes is unconscionable. We have, as we said in our statement, 185 known invasive species in the Great Lakes. Over and above those there are zebra mussels, and we all know the story about how much consequence they've caused. There's been some success with some of those over the years, but I think there's sea lamprey, Asian carp, and then there's the rest, I would say.
Would you disagree with that, Dr. Goddard?
