50 CFR § 622.33 - Prohibited species.
(a) General. The harvest and possession restrictions of this section apply without regard to whether the species is harvested by a vessel operating under a commercial vessel permit. The operator of a vessel that fishes in the EEZ is responsible for the limit applicable to that vessel. (Note: Nassau grouper in the Gulf EEZ may not be harvested or possessed, as specified in § 622.181(b)(1).)
(d) Gulf reef fish exhibiting trap rash. Possession of Gulf reef fish in or from the Gulf EEZ that exhibit trap rash is prima facie evidence of illegal trap use and is prohibited. For the purpose of this paragraph, trap rash is defined as physical damage to fish that characteristically results from contact with wire fish traps. Such damage includes, but is not limited to, broken fin spines, fin rays, or teeth; visually obvious loss of scales; and cuts or abrasions on the body of the fish, particularly on the head, snout, or mouth.
