Culturing more White River springs could probably help. They too have become smaller, but increasing the supply of PS and Salish Sea Chinook certainly won't hurt the orcas.

I should point out that the PSF presentation linked in "the truth" thread, indicates that if the Harrison and SF Thompson Chinook, mainstays of SRKW forage, don't rebound, the SRKWs may be screwed, regardless of any other actions taken by any state or provincial or federal authority.


We'll never achieve a substantive increase in the large fish phenotype without curtailing the rape of the nursery in the northern killing fields. The fish genetically programmed to become older larger chinook never get there because they are disproportionately exploited by the marine harvest machine.
