Here's a thought as to how this might eventually work "out".

The listed fish have maximum impacts set. At least in recent years, most of the take is given to the tribes.

One of the reasons for going selective is so that more hatchery fish can be taken per dead listed fish. If all fisheries are selective, this is a good thing.

But, if the tribes persist in fishing non-selectively they will need more listed impact fish in order for them to harvest more hatchery fish. I doubt that the tribes would voluntarily give up harvest of hatchery fish.
