Actually, they eat Dyes Inlet chum. It is necessary to look at the whale's migration patterns to fire what they want when. Historically, I doubt that Puget Sound was really great for Chinook except the Skagit. Modest numbers, but nothing like Fraser and Columbia. Makes sense to focus there.

Just how much, in the name of conservation, have we cut back on Chinook production in the Columbia? Any and every cut in hatchery production shifts predation to wild fish. Couple that with increased pinniped and bird populations and most idiots could figure out that the wild fish would suffer.

Nothing is going to be done to Alaska unless it forced onto them by the Federal Courts. Since nothing is done to them, BC will take WA fish to make up for what AK takes. And they will take WA fish in trade for the sockeye. Wilkerson pretty much tied Fraser sockeye to PS coho.
