Look what we have managed the fish into here in Washington state.

I have seen places on Kodiak mainland Alaska where the fish spawn ontop of each other. Species after species displacing the fertiized eggs from the ones before, because there are too many fish. We certainly dont get that with MSY/MSH, no we get one system after another to crash.

Why do you think that nature designed things the way they did. Why do you think that things evolved so that there was such an over abundance of fish, far too many for any given streams prime habitat that they had to spawn ontop of each other four or five times in a cycle.
