The stillaguamish hatchery program is small and limited by the number of natural-origin fish they can collect for broodstock. PSC exploitation rate indicator tag groups need to be 200K tags for statistical robustness. That means just about the whole program is tagged and because of the prior mentioned sampling in northern fisheries being clip only sampling, the releases are ad clip and cwt. If the program was larger - at least 400k, the could release the double index tag group that OncyT was referring to.
