Although some populations are below target levels, U.S. wild-caught red grouper is still a smart seafood choice because it is sustainably managed and responsibly harvested under U.S. regulations. Fishing gear used to catch red grouper rarely contacts the ocean bottom and has minimal impacts on habitat.

They engulf prey whole by opening their large mouths, dilating their gill covers, rapidly drawing in a current of water, and inhaling the food. Large sharks and carnivorous marine mammals prey on adult red grouper.

Red grouper are found in the western Atlantic Ocean from Massachusetts through the Gulf of Mexico and south to Brazil. Annual catch limits are used for red grouper in the commercial and recreational fisheries.

Both the commercial and recreational fisheries have size limits to reduce harvest of immature red grouper. The commercial and recreational fishing seasons are closed from January through April to protect red grouper during their peak spawning period.

To reduce by catch, there are restrictions on the type of gear fishermen may use and where they can fish. Minimum size limits protect immature red grouper.

Year-round and/or seasonal area closures for commercial and recreational sectors to protect spawning groupers. Red grouper is available year-round with peak catches in the Atlantic and Gulf of Mexico occurring during the summer and fall.

Red grouper flesh is white and lean with a notable lack of bones, and is very forgiving when cooked as it remains moist, firm, and has large flakes. Red grouper is considered the best tasting grouper with a distinct shellfish finish due to its diet.

Red grouper are protogynous hermaphrodites, meaning they all begin life as a female and eventually some may transform into males. Red grouper have large mouths with a slight under-bite, which allows them to eat their prey whole by dilating their gill covers and rapidly inhaling.

They also frequent areas with live bottom structures such as sponges, corals, and sea squirts. Red grouper act as “marine engineers” in their ecosystem by hollowing out flat-bottomed areas to create their home and attract mates.

This process provides habitat to other species such as spiny lobster, black grouper, red porgy, and vermilion snapper. Their grouper habitat utilization investigation looks at seasonal movement patterns in an attempt to improve populations and fishery management.

The If program allocates shares of the total commercial catch limit amongst individual fishers. Under the program, each fisher owns a share of the quota and can choose to fish it at anytime during the open season.

Strict commercial reporting requirements prevent fishers from harvesting more than their individual allocation. The Reef Fish FMP has been a success in allowing red grouper populations to bounce back from overfishing that had occurred on and off in the Gulf since the 1970s.

They are fairly long-lived and come together to spawn in large numbers, characteristics that make them vulnerable to fishing pressure. The Gulf of Mexico population in the was declared overfished in 2000 and then was rebuilt to target levels in 2007, according to the U.S. National Marine Fisheries Service.

The South Atlantic stock is no longer overfished, but a 2010 assessment showed it hasn’t been fully rebuilt. Grouper fisheries have high impacts on nontarget species, the Monterey Bay Aquarium reported.

Venting tools are also employed to make it easier for reef fish to survive when released. In the United States, red grouper management measures include permits, annual catch limits, fishing quotas, marine protected areas that are closed to fishing, seasonal closures, gear restrictions, minimum size limits, and data reporting requirements.

Prefer water temperatures between 66 and 77 degrees F. Like many other grouper, red grouper undergo a sex reversal, young individual females becoming males as they age. Grouper Malabar grouper, Epimetheus malarious Scientific classification Kingdom: Animalia Phylum: Chordata Class: Actinopterygii Order: Performed Family: Serranidae Subfamily: EpinephelinaeBleeker, 1874 Tribes and genera Not all errands are called 'groupers'; the family also includes the sea basses.

The common name grouper is usually given to fish in one of two large genera : Epimetheus and Mycteroperca. In addition, the species classified in the small genera Hyperion, Completes, Dermatologist, Graciela, Scotia, and Trio are also called 'groupers'.

However, some hamlets (genus Affected), the hinds (genus Cephalopods), the lyre tails (genus Various) and some other small genera (Gonioplectrus, Nippon, Paranoia) are also in this subfamily, and occasional species in other serrated genera have common names involving the word grouper “. Nonetheless, the word grouper on its own is usually taken as meaning the subfamily Epinephrine.

Groupers are Telecasts, typically having a stout body and a large mouth. They can be quite large, and lengths over a meter and the largest is the Atlantic Goliath grouper (Epimetheus Tamara) which has been weighed at 399 kilograms (880 pounds) and a length of 2.43 m (7 ft 11 1 2 in), though in such a large group, species vary considerably.

They do not have many teeth on the edges of their jaws, but they have heavy crushing tooth plates inside the pharynx. They habitually eat fish, octopuses, and crustaceans.

Reports of fatal attacks on humans by the largest species, such as the giant grouper (Epimetheus lanceolatus) are unconfirmed. They also use their mouths to dig into sand to form their shelters under big rocks, jetting it out through their gills.

The word grouper is from the Portuguese name, group, which has been speculated to come from an indigenous South American language. In New Zealand, “groper” refers to a type of wreck fish, Poly prion oxygenate, which goes by the Mori name haiku.

In the Middle East, the fish is known as hammer ', and is widely eaten, especially in the Persian Gulf region. The species in the tribes Grammistini and Diploprionini secrete a mucus like toxin in their skin called Rammstein and when they are confined in a restricted space and subjected to stress the mucus produces a foam which is toxic to nearby fish, these fishes are often called soap fishes.

The largest males often control harems containing three to 15 females. Groupers often pair spawn, which enables large males to competitively exclude smaller males from reproducing.

As such, if a small female grouper were to change sex before it could control a harem as a male, its fitness would decrease. If no male is available, the largest female that can increase fitness by changing sex will do so.

Gonochorism, or a reproductive strategy with two distinct sexes, has evolved independently in groupers at least five times. The evolution of gonochorism is linked to group spawning high amounts of habitat cover.

Both group spawning and habitat cover increase the likelihood of a smaller male to reproduce in the presence of large males. Fitness of male groupers in environments where competitive exclusion of smaller males is not possible is correlated with sperm production and thus testicle size.

Gonochoristic groupers have larger testes than protogynous groupers (10% of body mass compared to 1% of body mass), indicating the evolution of gonochorism increased male grouper fitness in environments where large males were unable to competitively exclude small males from reproducing. Many groupers are important food fish, and some of them are now farmed.

Unlike most other fish species which are chilled or frozen, groupers are usually sold live in markets. Groupers are commonly reported as a source of Ciguatera fish poisoning.

DNA barcoding of grouper species might help in controlling Ciguatera fish poisoning since fish are easily identified, even from meal remnants, with molecular tools. In September 2010, a Costa Rican newspaper reported a 2.3 m (7 ft 7 in) grouper in Cieneguita, Limón.

The weight of the fish was 250 kg (550 lb) and it was lured using one kilogram of bait. In November 2013, a 310 kg (680 lb) grouper had been caught and sold to a hotel in Dong yuan, China.
