Mycept,
You made the comment about low voltage current in the water during transport, Question I have is what would it need to be? Would a 9 volt or couple of them together do the trick for a small livewell? A 6 volt lantern battery? If the study shows that it helps I'm all for rigging up something that could attach to the underside of my live well hatch and running metal rods down to the water on each side. Heck I might even be able to invent something I could mass sell and turn some coin at it as well as help prevent mortality loss at tourneys.
