One problem on the stopping of hatchery Chinook production is that it would vastly reduce the H+W mix in the salt which used to be called the "pool". This would result in a even higher % of Natural Origin ( NOR ) WA Chinook caught in AK & BC unless their harvest is greatly reduced.

Oh Oh my bad the AK & BC intercept is the issue. Remember only 3% of Chinook caught in SE AK originate from AK so the lower the hatchery fish numbers are the greater the NOR impacts in the intercept fisheries.
Dazed and confused.............the fog is closing in
