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. Jordan, 1923 Tribe Epinephrine Sleeker, 1874 Aethaloperca Fowler, 1904 Affected Bloch & Schneider, 1801 Anyperodon Gunther, 1859 Cephalopods Bloch & Schneider, 1801 Chromites Swanson, 1839 Dermatologist Gill, 1861 Epimetheus Bloch, 1793 Gonioplectrus Gill, 1862 Graciela Randall, 1964 Hyporthodus Gill, 1861 Mycteroperca Gill, 1862 Paranoia Guillemot, 1868 Plectropomus Pen, 1817 Scotia J.L.B.

Smith, 1964 Trio Randall, Johnson & Lowe, 1989 Various Swanson, 1839 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.

Wiki source has the text of the 1905 New International Encyclopedia article Grouper “. These large fish are associated with hard structure such as reefs (both natural and artificial), rocks, and ledges.

It was easy for commercial and recreational fisherman to catch Nassau grouper and it soon became scarce. Because their range exceeds national borders, the best approach to their conservation is regional closed seasons.

Sampling of fish landed in the U.S. Virgin Islands and Puerto Rico during the 1970s and 1980s indicates that Nassau grouper were commonly caught, mostly from spawning aggregation sites. Currently, Nassau grouper are occasionally reported during underwater reef surveys at low density.

Coloration varies, but adult fish are generally light beige, with five dark brown vertical bars, a large black saddle blotch on top of the base of the tail, and a row of black spots below and behind each eye. They can be distinguished from other groupers by the vertical bars and dark saddle coloring along the dorsal part of the area preceding the tail.

Color pattern can change within minutes from almost white too bicolored to uniformly dark brown, according to the behavioral state of the fish. They take advantage of lower light levels at dawn and dusk, combined with the higher number of prey during changeover between diurnal and nocturnal fishes.

Nassau grouper are found in tropical and subtropical waters of the western North Atlantic. This includes Bermuda, Florida, Bahamas, the Yucatán Peninsula, and throughout the Caribbean to southern Brazil.

There has been one verified report of Nassau grouper in the Gulf of Mexico at Flower Gardens Bank. The Nassau grouper is considered a reef fish, but it transitions as it grows through a series of shifts in both habitat and diet.

As juveniles, they are found in nearshore shallow waters in macro algal and seagrass habitats. The main influences on where they live are not known, though water clarity, habitat, and bent hos (the community of organisms in the seabed) seem to be important.

Nassau grouper tend to spend a lot of time in one spot, often on a high-relief coral reefs or rocks in clear water. Larger fish tend to occupy deeper reef areas with greater vertical relief.

Nassau grouper pass through a juvenile bisexual phase, then mature directly as males or females. While adult Nassau groupers can change sex after hormone injection, natural sex-change has not been confirmed.

After 1 to 2 months of floating with the ocean currents, the larvae settle in nearshore shallow waters in macro algal and seagrass habitats. Adults are relatively solitary, living in areas that (patchily) overlap other groupers’ home ranges.

In some countries with protective regulations, there are too few enforcement officers to cover a large geographic area with many landing locations. Meanwhile, fish caught during closed season are held and later marketed as legal capture.
