I saw an evening news show documentary on the Copper River Sockeye and they contended that the Copper River fish aren't really any better than the other cold water sockeye. As I recall local markets/restaraunts tapped into the Copper River market some years ago when the fish were flown in quickly from the fishing grounds. Every year a big deal is made of the arrival of the Copper River Sockeye and thus created the high demand for the fish. No doubt... Sockeye's the best.
