Well, it's an interesting thing that happened. The slate of scientists, the same ones we're talking about funding, discovered this. The alewife produce an enzyme. That enzyme, when the lake trout would eat it, would break down thiamine. Thiamine is needed in the lake trout's eggs.
We lost the great fishery of lake trout with the sea lamprey. Everyone expected as they got the sea lamprey under control and reduced it by 90% that the lake trout would come back, but it didn't. It came back very slowly.
A lot of stocking of lake trout has been done every year for years now by the Ministry of Natural Resources in trying to help it get back. When the alewife crashed, suddenly it wasn't there any more. They're finding that the lake trout are reproducing naturally again, the wild lake trout. We're starting to see that fishery come back, only because it was being kept down because of this invasive species. No one knew why it was happening.
