Pithing the fish and immediately poking a hole in the heart provides excellent bleed-out. fish on the Scat Cat are typically installed head-first into a RSW slurry in a 50g plastic barrel. (lots of us call it the tuna margarita, bloody water sprays everywhere!) once rigored, they are packed in ice. once home, before I open the fish I rinse slime and loose scales off with the hose (FW). Loin out the fish with the skin side down keeping meat out of contact with the wet table. DO NOT RINSE, PERIOD!!! I don't vacuum-bag. I hand out almost everything to friends and neighbors and eat the rest as fast as possible !!! Steaks are always beautiful ruby red and irridescent. OP should throw deckhand overboard immediately if caught near his tuna with a knife and waterhose, LoL !!!
