I've been reading on another post about the best ways to preserve/freeze tuna. We expect to catch some yft out of Venice next month, along with some wahoo. What's the consenses about whether to leave any skin on prior to freezing? When we received the wahoo fillets from Devlin back in January, he had left the skin on. A couple of years ago the guy cleaning our yft in Port A removed all the skin. So what's the bottom line: Leave or remove any skin?? Or does it depend upon the species?
