Plunker, interesting to note that the "largest run on record" in the Columbia that the author talked about did not mention how many of those fish were wild and how many were hatchery.

If you are prepared to put your faith in hatchery fish that are raised by the government, then I've got some bottom land that I'd like to show you. I am not as confident as you. I'm also not prepared to recommend the breaching of the Snake River dams. I am waiting for some good science to show me the way. I would submit that going to some of the links that the Center for Global Food Studies has on their site did not fill me with confidence that they posess good unbiased science.
