You can do all the things you outlined above as 'tweaks' or improvements to the conservation process, but moving forward with rivers restoration has to take place as a continuous process. Personally, I am of the opinion that genetics are not some stasis condition, but they are constantly in flux, adapting to diet, climate, and whatever other influences that improve survivability. Purity doesn't matter. Improvement does. I submit to you that the genes of stocked brown trout in Valley Creek today are not the same as those from the hatchery put in the stream in 1979. Same is true of brook trout in Colorado streams, etc... I'm not sure how many generations it takes for a hatchery fish to improve its genetic structure, but they do, and those fish have adapted quite well, at the expense of natives in the same watersheds. That's why I want to improve streams as the major contributor to restoring natives. Chasing genetic purity takes our eye off the ball, in my humble, poorly informed, but instinctual position. The original post was asking about unanimity of purpose. I submit that watershed restoration is the road we must travel together.
