I think I understand the rationale. The rationale appears to be based on desired fishing. That is only logical if all parts of the natural environment are equally suited to the desired outcome. We know that they aren't. That's why I think the management plan is at cross purposes with what the respective WB tributaries can deliver. Case in point: North River NOR Chinook goals. If ever there was a river - a large creek actually - less suited to natural Chinook production, the North would be high on the list. Except that in WB, most streams are high on the list because they are not well suited to any significant amount of Chinook productivity.
As long as NOR Chinook are a WB priority, ultimately the NI gillnet fishery has to go. And if public funds were being expended responsibly, most WB hatchery Chinook production would have to stop.
