A lot of the commercial Dungeness fisherman down here in Southeast use zincs on their pots and have all sorts of ideas/theories on how electrolysis on their pots change their fishing. They say that the crab can sense/feel the electrical current and can be deterred by it. They say that Dungeness are the most sensitive from it and it makes the most difference when fishing for them; and less so for Kings and Tanners. Any thoughts/Ideas on this? It's kind of like line voltage for salmon fishing...a bunch of black magic maybe?
