There is a lot of factors at play. That's what makes managing these fish for MSY (Maximum Sustainable Yield, as per the Alaska Constitution) a very difficult task. The really odd thing is that the wild fish in most rivers are coming back on average a full 1 or 2 years earlier than previously assumed. Is it that the fishing fleet is hammering the later fish before they get in the river? Warmer ocean speeding maturity? Lack of feed? The what if's are limitless.It would be easy for me, as a commercial guy, to want to have the "ocean conditions" be the only reason (btw, "ocean conditions" is the catch-all for scientists to use when they just don't know). But I tend to agree with you - human interaction with the runs are causing this in some respect, but I don't know what it is. The wild runs being early and small as well suggests to me it is a bigger problem than hatchery management.
I don’t fault skillet or others for their profession. I appreciate those that can have an honest conversation and not simply regurgitate the party line.But, as skillet points out, fisheries politics has a lot more to do with money than honest science. Many of the problems are known and fixes exist. They aren’t fixed because there is too much money to be made. Trawlers harvest fish sticks and kill hundreds of thousands of kings (and halibut). Mixed stock troll fisheries are known to kill tons of bc and southern us fish. Stopping that would require a huge shift in Alaska’s approach and would necessarily cost ak and it’s fishers lots of money. And so it continues and we point fingers at tribes, habitat, unknown foreign harvesters and all the rest.Another thing that’s not talked about is how msy won’t allow us to increase spawning. If folks like skillet were forced to lay off our fish, we’d set seasons here in wa that would ensure we killed them once they got back. Any fish beyond he escapement goal, which is often artificially low to allow harvest, must show up in the planning model as a dead fish. If we improve habitat, the escapement goal stays the same and we kill all extra fish. The spawning population can’t and won’t grow because we make damn sure we kill every last possible harvestable fish. And usually more.
Ribka - netting the river is actually the best practice for controlling the amount of harvest. That’s not to say that the tribes always do so responsibly, but in theory it would be the best approach. Ak has lots of pretty closely managed terminal harvest designed to allow specific levels of escapement.Skillet - I’d be really interest in your pit tag data if you are willing to share.
