Good question Dave,
According to one of the Quinalts, the humptulips is netted solely for the income...

Over the past few years and the dismal commercial market for fish their profit has been between a few hundred to a few thousand. I would think that a buyout of commercial fishing rights may be accomplished somehow. (just talking the commercial not the ceremonial)

Perhaps it would be possible to let them fill that market with the hatchery surpluses instead of netting the wild runs.
