I disagree with you regarding farmed fish and hatchery fish. Hatchery fish ARE wild fish. 
You folks have some other problem up there but it's not the fault of the hatchery fish because they are "wild" salmon. In Southeast, we have a number of hatcheries and we seem to be doing ok, recovering from the old days of Cannery fish traps and massive over fishing. Hatcheries release the fingerlings from the fertilized eggs of wild salmon. Then the fingerlings swim down the creek back into the ocean where their parents came from. Then they try to survive in the ocean until it's time to return back up the same creek they came from to spawn. Have you ever seen how tiny they are when released back to the ocean ?
