If, in fact, it is the goal of NOAA to stop the Killer Whale decline then closing the northern interceptions is the best and fastest was yo do it. It will provide fish in Year-1. The hatchery proposal, even if works, will take 3 years from first egg-take to show a benefit, if the interceptions in ALL fisheries of the new production are held to 0. Which is faster than the benefit from any habitat work.

Which leads me to conclude that the Killer Whales can just go die.
