Thank you Brian. It will be a hard pill for Salmo, eyefish, and fleaflick to swallow that they are wrong. I doubt that all three will admit it. Maybe Salmo but not the other two. They have been brainwashed by the department and have another agenda to promote.
Another study that could also be easily done in similar fashion to this one is the impact of winter hatchery steelhead on wild winter steelhead for the Nisqually and Puyallup Rivers since those hatcheries were shut down. The wild fish populations there have not come back. Neither have they on the Sauk.

Bottom line: I would argue that hatchery fish are not to blame for the decrease in wild fish. We just need some artificial selection taking place in the hatcheries to keep up with the wild natural selection taking place in the rivers.
