Aha! Because hatchery fish cannot have any affect other than negative on wild fish, the hatchery program that is the "best fit" is either isolated from wild populations or is an integrated program where the hatchery fish are significantly outnumbered by the wild fish population so that the negative affects remain negligible.

By this standard, the Snider Ck program may fit, but due to lack of monitoring it is impossible to know.
