What is needed is a market for them they are good eating, this side of the pond it is called "rock" A solid tube of sweet meat no bones kids love it.
Next time you get a 'rock', put it on a sheet of tinfoil and squeeze a lemon on it. The electric charge generated with make it squirm around. Saw it on youtube.
I've answered a few requests to skin them for eating, but you and I may be eating a different species, or something. All the ones I've 'cleaned', even immediately killed, have stunk to high heaven. Or maybe they use some chemical to process them.
