With the hundreds of millions of Chinook having been planted out of their basin of origin there is no question but the stocks in those rivers have been adulterated.

Further, it is NOAA/NMFS's goal to accomplish exactly what you have written - allow evolution to take its course on born in the gravel fish. Of course the final product with be a genetic stock adapted to the current habitat and we all know how significantly that has been altered.

If that is what we want then go for it recognizing how it will continue to impact our fisheries for generations here in the PNW.
