I would never do this, erhm, because it is against some law about selling personal catch I'm sure, but I would imagine that once your freezer is full and your friends and family member's freezers are full, any extra seafood could be a welcome bartering tool. I have heard that one may be able to gift good seafood to others and find themselves gifted back with vegetables, sausages, physical labor, shoes, baby clothes, unwanted gift cards, etc...
