Relatively quickly, I'd just tell you again that I think the fundamental mechanism that regulates all salmon, all species throughout their distribution, is that when they enter the ocean, they survive better if they grow faster and quicker.
Remember that even in the best years, 5% of chinook salmon in the Strait of Georgia in the 1970s provided all the fish that everybody wanted. There were 95% that died, but no one really worried about that. Now 99% die, or 99.9%. You need to understand the natural mechanisms that have increased that mortality.
Again, the collapse of the commercial fishery all around the Pacific last year has to be a common mechanism. To all scientists, it is key that we understand that mechanism if we're going to understand the future of Pacific salmon.
