I agree that you seem well intentioned Cichlidfish. Many that lurk here are not.
There are a few of us about that even under the threat of banishment from the site, say what we mean and mean what we say. There are also many milksops about who form an opinion based upon what the soup of the day is and even then have no solid conviction about it.
I will be the first to admit that it pains me to see black bass on a stringer. Sometimes it does cause anger and other times I just shrug it off. It pisses me off especially when I see them coming out of small ponds. I love catching black bass a thousand more times than I ever would eating them. Even if black bass tasted like king crab, I would still turn 'em loose.
In regards to injuring fish badly that you have no intention of keeping - sh*t happens! I have been fishing long enough to know that no matter how careful you are when catching and handling fish, what you would like to happen doesn't always pan out.
I am sure that of the hundreds of bass I have caught, photographed and released, some didn't make it. Perhaps some of the fish that swam away looking no worse for the wear didn't make it either. I will never know but I still do do my best to handle good fish as delicately as possible. Bass are a tough breed like a few folks on here (unlike the pansy trouts and their fans) but they still have their limits. :P
The other day I had to leave a couple of tubes in nice fish because they choked it and I figured they'd have a better chance of the hook rusting out than me doing some hillbilly surgery trying to get my bait back. Who knows if they made it but there's always the chance they might have.
I throw crankbaits a lot and there are few feelings as good as a good crankbait bite when they fish hits your plug so hard it puts a foot of slack in your line. At the same time I cringe because I know how nasty treble hooks can be when the fish takes them deep.
Sorry for the long drawn out response but I do care about protecting our resources and do what I can to help in a way that suits me and who I am.
