Flame me for this, or set me straight, but:
I used to fish, but I no longer do. I would fish if it were necessary for me to do so. As a sport, absolutely not. I think driving a hook through a fish's mouth is cruel and painful to the fish. I admit, I do buy it fresh from local markets, but I don't have to actually see the fish being "drowned" and hooked. I figure if I can't bait a puppy on a pole, I might as well not do it to a fish.
If it is fact that the fish doesn't experience pain in the sense that we as humans perceive it, then, yea, I'll grab a few beers and sit out on the pier and fish.
