LT -- Thanks for the apology. No problem now. I appreciate it.

Smalma -- You could add to the list of references a paper by Kostow, Marshall, and Phelps, 2003, Transactions of the American Fisheries Society, reporting on a study in the Clackamas basin wher hathcery summer steelhead spawning in the wild had much lower reproductive success than local native wild winter steelhead. The problem was that the offspring of the wild-spawning hatchery steelhead survived pretty well to the smolt stage. Apparently their poor survival was in the ocean. So they took up food, space, etc. in the river and thereby presumably diminished the survival of juvenile wild fish they were competing with. This study was comparing summer run hatchery fish with winter run wild fish so it might not have too much to say about using broodstock close to the wild fish in a hatchery program.

As far as those of us who have e-subscriptions to (some) journals sharing articles goes, I think this practice is usually prohibited. I'll look into it more and see if it's possible at all. I think there has been a very thoughtful exchange of ideas and information on this thread.
