Could be. When the hacteries started to pump out Chinook it probably increased the overall numbers. It is also possible that the delayed release progarm, which kept fish in the Sound and increased the toxin loads in the fish, may have increased the body burden in the whales.

Another thing to at least ponder is that, if we are rather unwilling to let the wild Chinook runs to increase to feed the whales we may have to use the hatchery fish for that.
