That's flawed logic. Escapements are only one consideration for our hatchery fish as well... if we send them out they are actively competing with wild fish in estuary/marine/offshore environements. More survivors = more competition, again it's directly related. If we don't show a proficiency in harvesting the fish we are asking to be put out, they will pull the permits to do so. NMFS has made this pretty clear in the past.
