Why not reduce the limit on wild fish as a first step? And then in addition, what about reducing the number of wild fish a person can keep per year from these rivers that still have "strong populations"?

I personally don't keep any wild fish, period. However, that doesn't mean that I don't "take" wild fish. A fish that is hooked and released (fly caught or otherwise) is worse off for the experience.

And by the way, does anyone out there know of any studies showing that CnR is less lethal with a single barbless hook that a barbed treble? Other than what I consider common sense, I do not know of any studies supporting this. On the contrary, there have been some studies that explored this question, but many of the folks on this forum wouldn't be happy with the data.
