I wasn't referring to any sort of "emotional" stress. If a fish on the end of a line has a "fight or flight" response than how does that compare to someone jogging, unless a grizzly is after their behind?
I agree, a C&R fish is more likely to live than one that's caught and kept, but one that's left alone completely also has a higher chance of living than one that's been handled purely for "sport".
I'm not trying to call you out Ter, it just irks me that a lot of the people who have issues about disrespecting fish and all that jazz are purely C&R anglers who often angle many more fish in the name of sport than someone who goes out and keeps a few, enjoys the resource and then goes home.
