Salmo G is right on with his comments. I would like to add that fact that timing ends up being a really big problem because the tribes harvest with non-discriminate methods. They would want to harvest fish from the wild brood stock and due to the timing of the return would kill wild fish while harvesting those from the program. I for one don't want to see increased netting on the wild stocks. Now if the tribes would use a selective method of harvest I could see this working. I believe it would improve the strain of fish.
