The thing that bothers me about the process is that Feds can't evaluate the Tribal fishery separately from the NI. If there is no NI fishery (or Tribal) the run sizes are different due to lack of catch so the exploitations rates per day are different.

If they were to evaluate the Tribal fishery separately (as they apparently did a few years ago) it had to be in the absence of any other fishing./ Otherwise, that had to have approved some NI fishing.

I think snit has it rather well parsed out; the tribes are in charge of just about all the fishing in the state (see CT fishing in the Stilly). Pretty sure that oil WDFW opened up an extensive walleye fishery in Lake WA the Tribes would oppose it due to impacts to wild whatever's.
