No, the middle lakes: Lake Michigan, Lake Huron, and Georgian Bay. The charts presented show the biomass, the amount of energy in the lakes. What you see is this drop that took place around 2003, the big change that went down, and since then those lakes have been running at the same biomass level as Lake Superior’s. It's quite surprising. That was not the tradition. These lakes had a lot of biomass, had a lot of fish in them. What you're seeing is you take the food source out and you have this break in the food chain. But if you remove the filter, if you start to take the microscopic plants and the microscopic animals out of it, you start to lose that biomass. That's what we have right now, that change.
Can you still have a fishery? Yes, Lake Superior still has a fishery. But it's a very different kind of fishery from what we had in the past in those middle lakes.
