I've seen this story in a few places recently. I tracked down the abstract at PNAS but you have to pay for the full study, or wait until 6 months after it's published.
Hood River steel study making the news

LOL!
It actually takes a full scientific study to determine what I would figure to be common sense?
"Research shows that fish raised in hatcheries don’t do as well as wild fish, once they're released."
Genius!

Well that is true, but as I'm sure it's been said before...
The amount of common sense in a decision is inversely proportional to the size of the group making the decision.
What I'm most curious about is how they are framing that statement. From the abstract it looks like the hatchery descendant fish are returning in better numbers. So, from the get to sea, thrive and return standpoint they are doing well. The interesting info, such as how the following generations do after spawning outside the hatchery, or success of hatchery descendant wild spawning is hopefully included in the full study. I'm just not 10 bucks worth of curious to find out.

Man, ain't that the truth...especially in our "fisheries departments". Ph.D. does NOT always equal any amount of common sense. I've met with (and worked with) many folks at that educational level. They are good in their chose fields of expertise. But, they often lack any footing with the common world.

I don't have access to the full study, but Mark Christie gave a guest lecture about his Hood River study for my ichthyology class. What they found was that F1 fish that had good returns had poor F2 returns, and fish that F1 fish that had poor returns, had good F2 returns.
F1 fish are hatchery raised from wild broodstock, and F2 fish are then the wild spawned offspring of those F1 fish.
I like how you're making broad generalizations. The study performed was to track genetic adaptation to captivity. Make your own assumptions about "wild vs. hatchery".
