Nearshore has not changed that much. The nearshore fishery, which would be made up of largemouth and smallmouth bass, you'll find that at certain times of the year all the walleye will be in the nearshore. That has not changed a lot.
The biggest change in the Great Lakes has been the offshore, where the big fish are, where the big predators are, where the commercial fishing takes place. That's where the quagga mussels are.
The nearshore is a very small ring. If you take the edge of the Great Lakes and go 30 feet deep and you look at it, it's a very small ring. The vast body of the lakes is really offshore, but that's where you start to see the big change. Quagga mussels have now gone into the deeper water and have been doing the filtering process there.
The loss of the tiny shrimp, the diporeia, was big for the whitefish. Whitefish struggle. They're hanging in there, but they lost a lot of their weight. They lost a lot of their oils. A lot of the commercial fishermen were struggling. They weren't getting the same kind of quality product they were getting before, because the whitefish ate the diporeia as well.
Alewife also, their main food source was the diporeia.
