Having been in salmon management, from the 70s WDF prioritized Chinook and Coho for recs with one huge exception. A net fishery can harvest a lot of fish, in a short time.

Could an orderly Skok River fishery take 10,000 adult Chinook? I doubt it. Not to say they couldn't, or that the recs shouldn't be allowed opportunity. But, if the recs can't get the fish, the hatchery gets too many. Or, the Tribe will claim foregone opportunity and take the surplus.

Terminal fishing, which is by far the ecologically and biologically most appropriate, also requires efficient removal of surplus. Nets are much more efficient than orderly hook and line.
