There are cases where significant habitat alteration can result in significantly increased fish production. For example, when you look at prairie reservoirs, a dam is constructed and a reservoir is made. The most popular fish in that neck of the woods is the walleye, and when a reservoir is made, the walleye population just booms. The productivity skyrockets. It's called the reservoir effect, as you well know. A single-minded focus on just habitat, habitat, habitat also has to reflect fish production, if you know what I mean. I'm not saying it quite as clearly as I should, perhaps.
Could you comment on that last point? Then I'll stop.
