MM, you've hit on one of the reasons for developing integrated programs. That is, where the straying of hatchery fish cannot be controlled (perhaps one should say WILL NOT be controlled), there is a far lower negative effect (at the same rate of spawning), with those strays being from hatchery fish derived from natural spawners versus Chambers Creek, Big Creek, Skamania stock, or any other pure hatchery population.

Todd is absolutely wrong in his absolute view of the results. If you want to find out the real science behind this and the real results of monitoring of numerous integrated programs (meaning places where people HAVE LOOKED), do not accept the "facts" that you read on BB's like this, but look into the literature and reports of real scientific groups like the HSRG, or the Independent Scientific Review Panel (ISRP) on the Columbia River. Their reports and summaries will provide different results than the simplistic dogma that you have in this thread.
