I think even if it is fairly low (the release mortality) it still has an impact.
5% mortality = 5 dead fish out of every 100. Do that enough days and you killed a fair number of fish. I agree that most of us handle the fish properly, but it wouldn't surprise me if the mortality rate on the fall blitzing fish (like the pic last week) is 30% or more.
This comes from a known carnivore (me) who has no problem killing fish, as long as they are legal and eaten, so I'm definetly not a C&R only guy, but leave the babies alone!
