Crettke, Tom B has given you a good start on the hatchery vs wild stuff. There is a ton of literature out there on that. My library is at work, so I don't have specific papers/citations at hand, but suggest you look at the American Fisheries Society website for recent publications in Trans. Am. Fish. Soc. and in "Fisheries" from AFS. Look at Journal Table of Contents. There has been some very recent discussions in AFS publications about the role of hatcheries in either impacting or potentially aiding recovery of threatened populations. Can J Fish. Aqu. Sci. table of contents might also have some interesting stuff. Other sources would be a web search for "CRITFC AND Methow", and "USFWS AND Steelhead AND Methow". If this is for college/university, your library should have a literature search engine to allow you search the peer reviewed journals at no charge. The regs that prohibit taking fish out of the water before release just make physiological sense to reduce stress and post release mortality.
