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.
In November 2013, a 310 kg (680 lb) grouper had been caught and sold to a hotel in Dong yuan, China. ^ a b c d e Richard van der Loan; William N. Scholar & Ronald Cricket (2014).

Entries are added and mistakes corrected by a team of kind volunteers from around the world. It might be called grouper or sole on the menu, but if you test your dinner’s DNA, there’s a decent chance you’ll find that you’re actually eating farm-raised Vietnamese catfish.
According to a 2015 study, a diner would have to eat between 100 and 300 kilograms (220 to 660 pounds) at one sitting to get sick from antibiotic, pesticide or preservative residues. Monterey Bay Aquarium’s Seafood Watch program ranks fantasies in its lowest category, ‘avoid,’ for two big reasons.
Adding to this are concerns that freshwater fish farming in the Mekong has slashed wetland habitat for endangered otters, birds and turtles. Additional Asian countries are adopting fantasies farming, and demand has fallen in Europe and North America as governments and buyers step up calls for better hygiene and food safety.

The properly is subangular with the serrations at its angle being slightly enlarged and the upper edge of the gill cover is straight. The They are dark reddish brown on the upper part of the head and body, shading to paler pink on the underparts, they are marked with lighter spots and blotches across their body and there are darker margins to the fins.
This species has a maximum published total length of 125 centimeters (49 in), although they a more commonly found at lengths around 50 centimeters (20 in), and a maximum published weight of 23 kilograms (51 lb). The red grouper's typical range is coastal areas in the western Atlantic, stretching from southern Brazil to North Carolina in the US and including the Gulf of Mexico and Bermuda.
Spawning occurs offshore between January and June, peaking in May. While primarily eating benthic invertebrates, the red grouper is an opportunistic feeder in the reef community.
The diet commonly includes mantid and portend crabs, juvenile spiny lobster, and snapping shrimp, with the occasional fish. The red grouper is of moderate size, about 125 cm and weighs 23 kg or more.
When aggravated (they are highly territorial) or involved in spawning activities, these fish can very rapidly change coloration patterns, with the head or other parts of the body turning completely white, and the white spots appearing more intense. Red grouper (Epimetheus Mario) on an excavated site on Pulley Ridges on the West Florida Shelf Red grouper actively excavate pits in the seafloor.
They start digging in the sediment from the time they settle out of the plankton and continue throughout their lifetime. They use their caudal fin and their mouths to remove debris and sediment from rocks, creating exposed surfaces on which sessile organisms actively settle (e.g., sponges, soft corals, algae).
The exposure of structure also attracts a myriad of other species, including mobile invertebrates and a remarkable diversity of other fishes, from bodies and butterfly fish to grunts and snapper. The lionfish Steroid Holsteins started invading red grouper habitat by 2008, from Florida Bay to the Florida Keys and offshore to Pulley Ridge, a despotic coral reef on the West Florida Shelf west of the Dry Tortugas.
Known for being extremely capable predators on small reef fish, scientists are very interested in determining the extent to which their invasion changes the functional dynamics of associated communities. IUCN Red List of Threatened Species.
Spotted Coral Grouper /Coral Trout Plectropomus maculate (Bloch, 1790) Mandarin: (Shi ban you), (QI XING ban), (Tai XING ban) Malay: Iran Seraph sun oh pi sang, Seraph Bar Teacher/Tolkien: Ang Gas, Groupers are highly prized food fish especially at seafood restaurants where they are often seen swimming in tanks.
My wallet had its first brush with a live grouper almost 20 years ago when I just graduated from medical school. After I got my first pay-check, I treated my family to a seafood dinner at one of the Cantonese restaurants in Sydney.
Others maintain that it is because the fish gropes around the nooks and crannies in the coral reefs looking for food. In Singapore, you will frequently find table sized groupers swimming in tanks in live seafood restaurants.
Magnate Tailpiece are generally two types of red groupers seen at the wet market. Their colors can range from olive green to reddish brown depending on where the fish are caught.
The bluish spots on the Coral Trout, p lectropomus maculate are larger and oval. There is also a blue ring around the eye and the tail fin is described as marginate meaning that it is con caved in shaped but not definitely forked.
The ones from Indonesia tend to be more intensely orange-red while the ones from the local waters are pale orange. Olive colored coral leopard grouper These fish can grow to a length of 120 cm but the larger specimens are usually around 70 cm at the market.
Larger sized fish are usually cheaper and their meat is usually sliced and used for soups and stir fries. The cross-section of the body is also rounder than the similarly spotted relate and dusky tail groupers which means that the flesh tends to be thicker.

It is a superb eating fish and is highly prized in Hong Kong and is second only to the Sew Ma or Napoleon Wrasse. The color ranges from greenish white to light greenish brown with large widely spaced black polka dots all over the body, and so they are sometimes also known as Polka dot cod.
Giant Grouper, Giant Sea bass Epimetheus lanceolatus (Bloch, 1790) Mandarin: (Long Dan) Malay :Iran Erlang, Seraph Per tang Teacher/Tolkien/Cantonese: Long Dan Young specimens such as the one above have dark brown backs and light yellow undersides.
The owner of Grouper King, Johnny Tan was the one who is believed to have started the trend of eating the giants back in the 1990’s. The value of the fish lies in the large amount of collagen found in its skin, head and fins.
This grouper is almost entirely covered by large hexagonal patches of dark reddish-brown color in a honeycomb pattern. There are oblique dark bands just below and slightly in front of pectoral fin base and these are characteristic of this grouper.
Six bar grouper /Six band rock cod Epimetheus sexfasciatus Malay: Seraph been Tolkien: Kay key Cantonese: Deck pan This is a small grouper that grows to 26 cm and distinguished by combination of bars on sides and spotted tail.
This fish is similar in shape to the Leopard Grouper but not as commonly found in the wet market. The color is whitish beige to pale gray with numerous blue spots with dark edges on head, body and fins.
This photo was taken at a live seafood restaurant and is a fish that has been caught in local waters. But as I have delved more into the tremendous varieties of fresh seafood that the Hong Kong local wet markets make available I have realized that some fish are not small.
Hume... I'm thinking this image doesn't do justice to this giant of the seas. Let me show you a video of the Giant Grouper that snatched a shark from a fisherman.
Check out this cool giant fish on shark action! I guess the longer they live (and the more sharks they eat) the bigger they get.
Directions: Soak dried tangerine peel in warm water for 15 minutes or until soft enough to slice through. Scrap off the white pith on the inside of the peel with a spoon.
Place tangerine peel and ginger evenly over the top. Steam over high heat for 5-8 minutes, or until the meat is cooked through, flakes easily and is no longer translucent.
