At least in the past, WDFW concerned itself only with the bio/political issues surrounding conservation fish. Open/close seasons. There were times when toxic algae blooms occurred that WDFW left the fishery open since there was no conservation reason to close it; it was up to DOH to rule on eating safety.

As to the Atlantics, WDFW sees they need to be removed (and you need a license). DOH will rule on food safety.

As has been alluded to here, the PS-resident Chinook and coho (hatchery reared specifically to remain) are quite hot for toxins. WDFW still stocks them as they support a desired fishery. The catching is their concern, the eating is DOH's.
