I've lived next to two different reservations in WA state and I can confirm the fantastic equipment.
Also, on a random tour of the Leavenworth fish hatchery, we stumbled upon a fishery-management-sanctioned culling of "excess" fish at the Leavenworth fish hatchery into large blue food grade containers as part of tribes "share".
The whole story of where the fish are going is useful, even if it contradicts your preconceptions.
