Back in the day the winter black mouth fishery hammered Puget Sound Spring Chinook. But there were so few springers relative to the black mouth that it "it made no sense" to sacrifice so much much catch and opportunity to save so few fish.
I do remember DOF in the mid 80's closed the Blackmouth fishery in area 11. If I remember right, it closed in Feb to protect the White River Spring Chinook returning to the Minter Crk. Hatchery. They wanted to preserve the genes in a hatchery environment. No hatchery on the White then. Now the Muckleshoot hatchery produces them in decent numbers. Wish we could get a chance at em in the river, but the salt guys catch our share up North.
