Ocean conditions dictate overall abundance, habitat dictates abundance during poor ocean conditions.
Yet we don't have any recovery even during good ocean conditions, just look at the steelhead populations, good ocean conditions and bad ocean conditions yet stocks fail to recover, in spite of decades of no retention.
Steelhead have failed to recover even with the no take policy, harvest reform hasn't help recover any stocks, anywhere from northern Calif. to the Canadian border, with or without Tribal influence.
Calling for more of the same just seems like making the same mistakes over and over, but expecting different results.
