“Steelhead turned out by hatcheries quickly evolve into a kind of swimming livestock with a poor chance of surviving in the wild and may carry their inferior traits into wild populations that biologists are trying to save, a new study of fish in Oregon’s Hood River has found.”

This is hardly a surprise. Even with this research nothing will really change for Idaho unless there is a drastic change of values which I find unlikely. It has long been known that hatchery fish are vastly inferior to wild fish and, with steelhead in the upper Salmon, vastly outnumber the wild fish. I assume that it would be very difficult to find a place where wild fish would not breed with hatchery fish because the numbers are so skewed towards hatchery fish that swim up every tributary where wild fish would spawn. I think that the idea that there are any truly wild steelhead, meaning no hatchery influence at any point, in the upper Salmon drainage to be rather far fetched.
