Todd's point, shared by others, is that the total harvest is limited by the take of ESA fish. If 10 ESA fish is the limit, then when they die the fishery is done. It doesn't matter where or how they die. It doesn't matter who kills them; 10 will die.

The harvest of hatchery fish is limited now by number of listed fish. So, one can reduce the number of hatchery fish so that a non-selective fishery can proceed. Or, one can fish selectively, kill the listed fish at a slower rate, and take more hatchery fish. That is my understanding of the goal of making the gillnetters go selective; access to more hatchery fish at the same cost in listeds.
