Great info - thanks for the link!
Prior to reading the study data, my "gut" told me that fish tend to inhale bait and that internal damage was the likely result. I can count on my two hands the number of times that I have deeply hooked fish using flies. When I did, I kept the fish. Nice to have my opinion backed up by science.
Now that the rivers have come down, it's time to do some, uh, "research!" My backyard river's looking sweet and the Animas in Durango looks mighty fishy. And the weekend is upon us...
