Biology & Habitat

Appearance

Red grouper have robust bodies with small scales. Their head and body are dark reddish brown, shading pink or reddish below with occasional white spots on the sides and black spots on the cheeks. They have large mouths with a lower jaw that often projects slightly beyond their upper jaw, with bands of slender, sharp teeth, and usually a few stout, fixed canines. Their large mouths allow them to eat their prey whole.

Biology

Red grouper grow slowly, up to almost 50 inches long and more than 50 pounds. The oldest recorded red grouper in the South Atlantic was 26 years old and the oldest recorded in the Gulf of America was 29 years old. They are protogynous hermaphrodites—they begin life as females and sexually mature when they reach 4 to 6 years of age. Some later transform into males, most often between the ages of 7 and 15.

Where They Live

Range Red grouper are found in the western Atlantic Ocean from Massachusetts through the Gulf of America and south to Brazil. Habitat Red grouper are referred to as shallow-water grouper because they’re common in waters 10 to 60 feet deep. Juveniles prefer grass beds, rock formations, and reefs in shallow, nearshore waters. They move offshore as they mature.

Commercial Fishery & Harvest

Commercial fishery: In 2024, commercial landings of red grouper totaled 2.8 million pounds and were valued at $16 million, according to the NOAA Fisheries commercial fishing landings database . Gear types, habitat impacts, and bycatch: Commercial fishermen mainly use hook-and-line gear, including longlines and handlines, to harvest red grouper. Trawl gear, fish traps, and bottom longlines are prohibited in some areas to reduce bycatch. Several areas are closed to all fishing to protect snappers and groupers, including red grouper. Sea turtles and other reef fishes, such as snappers and groupers, can be incidentally caught while fishing for red grouper.
