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.
