All fins, including the tail, must remain naturally attached to the shark through offloading, except under the conditions specified in paragraph (c)(5) of this section. While on the vessel, fins may be sliced so that the fin can be folded along the carcass for storage purposes as long as the fin remains naturally attached to the carcass via at least a small portion of uncut skin.
