At least the AK hatcheries that are providing those mega-inlet fisheries are paid for by the commercial users. They tax themselves to fund those facilities. Which is why, if memory serves, most are chum, pink, and sockeye. Net fish that are not highly sought after in the marine mixed-stock hook and line fisheries.

WA commercials (non-Tribal, anyway) could do the same. They may have tried it with the Hood Canal chum a few years back but not sure how that flew in the Leg.
