If my memory serves me right, during the 5 years I lived in the beautiful State of Oregon, the fish hatcheries more than replenish the salmon population, and their spirit will live on to balance the fish markets with them as well assure that for generations there will be an abundance of them. As long as Oregon State U. Is open, the Salmon will keep on keeping on. I was a student there back when, and their professors were great supporters of both current marketing and in nature, replenishing their species of healthy fish for the future. I confess, however that was a long time ago, and I live half a continent away from ,Corvallis, home of the OSU Beavers.
