But surely, Dr. Taylor, you will make a distinction for non-native species that have been introduced into the Great Lakes that have actually benefited fisheries. I'm thinking of species like the steelhead trout and the Pacific salmon, both of which replaced lake trout and Atlantic salmon that had been extirpated. We're not talking about those kinds of species. They are clearly beneficial.
