A start to save king salmon would be to stop killing them in the ocean by the 10s of thousands and dumping them overboard as by-catch. As you eluded to, we can have the best habitat and no fish in it... The trawl fishery in the Bering Sea kills more salmon dumps them overboard, than are harvested in Alaska by other means. Same goes for many other species. Its sickening... They dump nearly and equal value of fish over as they keep. All so we can eat those cheap McFish sandwiches.
Bumping this for anyone who is not tracking
