This is like an old boys forum where people follow blindly and are not open to change. I have yet to hear someone say that generating some natural selection in the hatcheries would be a bad thing.

Let me see if I can post some graphs demonstrating Hatchery returns being worse than native returns. Its limitation is that the native numbers are small so there is more room for error but it definitely shows the trend. The only one that it does not show it for is fall Chinook.
