50 CFR § 622.276 - Landing fish intact.
(a) Dolphin or wahoo in or from the Atlantic EEZ must be maintained with head and fins intact, except as specified in paragraph (b) of this section. Such fish may be eviscerated, gilled, and scaled, but must otherwise be maintained in a whole condition. The operator of a vessel that fishes in the EEZ is responsible for ensuring that fish on that vessel in the EEZ are maintained intact and, if taken from the EEZ, are maintained intact through offloading ashore, as specified in this section.
(b) In the Atlantic EEZ, dolphin or wahoo lawfully harvested in Bahamian waters are exempt from the requirement that they be maintained with head and fins intact, provided that the skin remains intact on the entire fillet of any dolphin or wahoo carcasses, valid Bahamian fishing and cruising permits are on board the vessel, each person on the vessel has a valid government passport with current stamps and dates from The Bahamas, and the vessel is in transit through the Atlantic EEZ with fishing gear appropriately stowed. For the purpose of this paragraph, a vessel is in transit through the Atlantic EEZ when it is on a direct and continuous course through the Atlantic EEZ and no one aboard the vessel fishes in the EEZ. For the purpose of this paragraph, fishing gear appropriately stowed means that terminal gear (i.e., hook, leader, sinker, flasher, or bait) used with an automatic reel, bandit gear, buoy gear, handline, or rod and reel must be disconnected and stowed separately from such fishing gear. Sinkers must be disconnected from the down rigger and stowed separately.
