Todd -
Mark's study was in Oregon; it involved both coho and steelhead. Bottom line is that it is part of a growing body of evidence that using wild broodstock is not the "magic bullet" most hoped it would be. It confirms what has been suspect for 20 years - that is: using wild broodstock in many cases is counter productive. That is not to say that there aren't places that wild broodstock aren't helpful just that before embarking on such programs careful analysis is needed regarding the goals of the hatchery program and whether that is compatible with wild fish needs.
