I believe it is important to know what criteria is being applied so as to be able to properly understand what constraints are at play.

Your "Is this (segregated) hatchery population still essential for recovery?" question is succinct and leads to further ask if it is any more essential than other hatchery origin Chinook stocks in Puget Sound. If not, then why not clip or simply discontinue raising those as hatchery fish? Those are rhetorical; next step will be to ask WDFW.

Again, thanks for your insight.
