I see no physiologic reason this should work. About the most you could expect from pouring 7-Up on a wound would be some weak antiseptic action and that is very unlikely. I also think you would have to observe the bass for a number of days to conclude it would really survive. Wound infections would not produce mortality this quickly, I am pretty sure, and I would think that starvation from inablilty to feed would also be a cause of death.The main cause of death you would rule out with 28 hr of observation would be hemorrhagic death.I fish barbless to avoid excess trauma in case of a deep hookup. That is, unless I plan on killing what I catch for a specific reason.
