Only one hatchery in SE produces pinks.
Hatcheries don't produce kings because they lose money on them, it costs too much to raise them vs what they make back when they return. Unfortunately no hatchery will produce just coho/kings without some outside support from a hatchery that produces pinks/chums or government funding (Little Port Walter).
There is a guy that keeps trying to start a king hatchery at Baranof warm springs, he wants to do something like 100 million kings. Keeps getting rejected and gets a lot of opposition from locals because "they don't want to look at a hatchery". It is a good spot for a hatchery and it could be successful.
Port Armstrong is doing something groundbreaking with their coho production. They send half their production to saltwater before the fish smolt, at around 5 grams. The limiting factor for raising coho is freshwater rearing space. If they return well, it could mean that hatcheries could ramp up their coho production without changing their freshwater rearing space. This will be the first year for a return from about a 2.5 million smolt release of these fish so it will be interesting to see how they return.
