This debate always hits a nerve! Can a Senko type bait with a single hook be any worse than a lure full of trebles? To me treble hooks are brutal on a fish. I hate using them but sometimes forced to use that type of bait.
If people would just set the hook when they feel the fish there wouldn't be that problem! It's kind of like the guys I watch ice fishing that let the fish run with the shiner what seems like forever! Flag pops, feel fish, set hook! It's not complicated!
Like thelucky stated, a lot of the fish are swallowing baits that are thrown off the hook. I have watched bass swimming the shallows pick up a soft stick bait, drop it, pick it up again and swim away. I'm sure this happens with all scented soft plastics. It bothers me, but what can you do?
I am talking about plastics without a hook! Nothing you can do when the bait gets thrown off. I don't eat freshwater fish so I don't keep them. That is why I get concerned when a fish gets mangled by hooks. I crimp my barb on soft plastics so I have never had a problem with a deep hook.
