Rich..that's exactly the problem though...humans have changed things over the centuries. We have rearranged what was here and we have screwed it up. What we are doing now is running around mitigat ing the damage we have done. The question about Sockeye not belonging in the Cedar is another debate. Now that they are here and are succeeding and their presence provides a viable fishery for 10's of thousands of people why not keep them? I think you are saying they harm wild fish...if not then what's wrong? The trout issue is a side argument to my original posting.
