(d) Seasonal closure of the recreational sector for shallow-water grouper (SWG). The recreational sector for SWG, in or from the Gulf EEZ, is closed each year from February 1 through March 31, in the portion of the Gulf EEZ seaward of rhumb lines connecting, in order, the points in the following table. During the closure, the bag and possession limit for SWG in or from the Gulf EEZ seaward of the following rhumb lines is zero.
|Combined stock ACL black grouper, scamp, yellowfin grouper, and yellowmouth grouper – 710,000 pounds|

Yellowmouth grouper is found in the western Atlantic from the Gulf of Mexico, south to the Bahamas, Antilles and Brazil. It is most common off southern Florida. This fish has a pale tan to brownish body with small scattered, but close-set, brown spots on its back and sides. Yellowmouth grouper is aptly named as its distinctive feature is the prominent yellow coloration at the corners and inside of the mouth. The spiny dorsal fin margin is also a yellowish color. These features can help distinguish the yellowmouth from scamp. Juveniles are tricolored but become blotchy with age. The pattern on the body of juveniles mimics that of the juvenile clown wrasse. Interestingly, the juvenile yellowmouth may mimic juvenile clown wrasse behavior in order to approach unsuspecting prey.1
Maximum observed age: 28 years (Gulf of Mexico)2; 41 years (Trinidad and Tobago)2
Age at maturity: 3 years3
Maximum weight: 22.49 pounds (10.20 kilograms)4
Maximum length: 33.07 inches (84 centimeters)5
Life History and Distribution
Within its range, yellowmouth grouper prefers coral reefs and rocky bottoms up to approximately 490 feet (149 meters). Not much is known about its reproductive behavior or spawning aggregations. This species of grouper is a protogynous hermaphrodite: fish are born as females and transition to males at some point in their adult life. In the Gulf of Mexico, yellowmouth grouper appears to spawn year-round with peak spawning in April and May.
