Way back when WDF would restrict fisheries in the ocean in order meet escapement needs. Then, if anywhere on the coast escapement was exceeded there was hell to pay because those surplus fish were wasted and could have been caught.

In the long run, mixed stock fisheries of any kind are hard to manage. Mixed as in hatchery/wild or (say) chum/steelhead in Nisqually. Whatever you do, one run gets under fished and one gets overfished.
