There is a question about if they want to save money or cause pain. As alluded to, Chinook fingerlings, pink, and chum are by far the cheapest salmon to produce. Short rearing, little foods and so on. Cutting coho, steelhead, and yearling Chinook saves much more money.

Same with trout. The legals are expensive, the kokanee are cheap as are all the fingerling trout. The devil will be in the details, and the devil is making the choices.
