When you go to Court, the decision is made based on case law. Which, in the case of Boldt, would mean sharing is 50:50. When you sit down and "negotiate", you can agree to anything.

Oncy is right about intentional over harvest of wild stocks. WDFW and the Tribes agreed to a management plan for PS. One of the foundations was that every stream would have at least one (1) species managed as wild. This was to ensure that habitat was protected. (ok, that was th concept). Skagit and Stilly/Snoh were all wild, the rest had as few as one.

Interestingly, the Green was managed for wild Chinook. Hatchery coho and there were no chum and pink. Then, because of the presence of unmarked hatchery fish, the escapement was lowered because they couldn't hit the initial one. And called it MSY.
