Back when there was a reasonable run of LW sockeye there were few guys who had A10 dialed in for them. To my knowledge they never gave up the secret but checkers found them to be pretty successful.

Sockeye do bite in the salt. One year the Canadian trollers took almost all of the harvestable Chilko fish. Because of the way the treaty was written these fish did not count against the 50:50 sharing and the only thing that made it to Convention Waters was the escapement. The Canadians are much better trollers, if you goal is to catch fish, than the US guys. In addition to sockeye they could do pretty well on chum, too. Plus the occasional 1,000 coho day.
