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).

Wiki source has the text of the 1905 New International Encyclopedia article Grouper “. “Adult gag grouper live in nearshore waters from coastal North Carolina south to Brazil and as well as in the Gulf of Mexico.
Smaller gag are a lot of lighter in coloring, and have numerous dark brown, or charcoal, kiss-like marks along their sides. “Young gag grouper will live in oyster reefs, estuaries and seagrass beds from Massachusetts to Cape Canaveral, Florida.
The coloration of red grouper helps to distinguish this species from gag with its head and body being dark reddish brown, shading pink or reddish or even pale pink along the lower part of its body,” Nash said. “In North Carolina, gag will typically spawn in February and have clear larvae, which then make their way into estuaries.
As water temperatures start to go down in the fall, juvenile gag will migrate from estuaries to offshore hard bottom habitat and larger members of their species,” said Seward. Seward noted that all grouper are considered protogynous intersex, “that is they start their lives as females, and a part of the population will morph, or make the change, to males as they get older.
Females start to reach sexual maturity when they are about 24 inches in total length and about 3 years old. They are voracious predators, and will feed on whatever they can capture including scad, snapper, grunt, sardines, crabs, porgies, shrimp and squid, said Seward.
Red grouper sitting on sand habitat 45 degrees to camera full body view mouth open. In addition to their color, red grouper can be distinguished from gag by the sloped, straight line of their spiny dorsal fin.
“The red grouper is also a protogynous intersex and females are sexually mature by the time they reach 4 years old,” Seward said. Females typically will let go an average of 1.5 million pelagic eggs that stay at the surface for between 30-40 days before finally settling down to the bottom.
“Red grouper may live to be as old as 25 years of age, with older specimens reaching a size of 32.5 inches and up to 25 pounds. They will feed on lobster, shrimp, octopus, crabs and fish that are found close to their preferred reef habitat,” Seward said.
Bottom fishing is the best way to catch gag grouper, using live bait, including squid and cigar minnows. Use a depth finder to find deep-water rock ledges, artificial reefs and shipwrecks, a gag grouper ’s favorite hiding place.
An annual shallow-water grouper spawning season closure runs Jan. 1-April 30 in federal waters off the coasts of North Carolina and South Carolina, except red grouper, for which the season remains closed until June 1. Recreational and commercial fishermen are required to use hooking tools when fishing for the snapper grouper species.
“This prohibition does not apply to fish harvested, landed and sold before the annual catch limit is reached and held in cold storage by a dealer,” said North Carolina Division of Marine Fisheries Executive Assistant to Councils Steve Poland, who is also a representative with the South Atlantic Fishery Management Council. A stock assessment update, Sedan 53, for red grouper was completed in February 2017 using data through 2015.
Therefore, on Sept. 27, 2017, NFS sent a letter to the council stating that the South Atlantic red grouper stock was not making adequate progress toward rebuilding. So, NFS took steps in 2018 to immediately end overfishing of red grouper by reducing the total commercial and recreational annual catch limits, based on the acceptable biological catch recommendation from the council’s Scientific and Statistical Committee.
Continued harvest at the levels specified in Abbreviated Framework Amendment 1 is expected to allow for rebuilding the red grouper stock within 10 years, but because the red grouper stock is not projected to fully rebuild by 2020 (Sedan 53), the council must also “For red grouper, this final rule extends the closure season formerly from January to April, to January through May of each year for the next ten years for the commercial and recreational portions off North and South Carolina, and establishes a commercial trip limit,” said Poland.
This final rule establishes a commercial trip limit for red grouper harvested in the South Atlantic EEA of 200 pounds, gutted weight. The trip limit is expected to help rebuild the red grouper stock by discouraging directed commercial fishing for the species, although it is not likely to substantially reduce the current level of commercial harvest of red grouper, according to the National Register.
“The council selected a commercial trip limit that in combination with extending the spawning season cloture for red grouper off North Carolina and South Carolina would help keep down harvest numbers to help rebuild the stock,” Poland said. You can help pay some cost by sponsoring a day on CRO for as little as $100 or by donating any amount you're comfortable with.
Groupers are a species of fish that belong to the Epinephrine subfamily of the family Serranidae. As telecasts, all types of grouper have a stout body and a large mouth and are weak swimmers.
Irrespective of the types of grouper you wish to target you can catch large ones with lures, live and dead bait. If you are casting in the shallows, use jerk bait and retrieve it erratically to lure the fish out in the open.
You will need heavy tackle, especially if there are a lot of rocks under the water where you are fishing and a braided line that can withstand the powerful pull of a caught grouper. If you are using spinning tackle, make sure that the reel is heavy enough to withstand an 80 to 100-pound test mainline and a low gear ratio to give you more control.
This tackle will come in handy when the panicking grouper fish tries to swim under a ledge to break the line. For live bait, use pinkish, grunts, blue runner, sardines, and mullet.

Its range includes the Florida Keys in the US, the Bahamas, most of the Caribbean and most of the Brazilian coast. On some occasions, it is caught off the coasts of the US states of New England off Maine and Massachusetts.
In the eastern Atlantic Ocean, it occurs from the Congo to Senegal. Young Atlantic Goliath groupers may live in brackish estuaries, oyster beds, canals, and mangrove swamps, which is unusual behavior among groupers.
They may reach extremely large sizes, growing to lengths up to 2.5 m (8.2 ft) and can weigh as much as 360 kg (790 lb). The world record for a hook-and-line-captured specimen is 308.44 kg (680.0 lb), caught off Fernanda Beach, Florida, in 1961.
Considered of fine food quality, Atlantic Goliath grouper were a highly sought-after quarry for fishermen. It is a relatively easy prey for spear fishermen because of the grouper's inquisitive and generally fearless nature.
They also tend to spawn in large aggregations, returning annually to the same locations. Until a harvest ban was placed on the species, its population was in rapid decline.
The fish is recognized as “vulnerable” globally and “endangered” in the Gulf of Mexico. The species' population has been recovering since the ban; with the fish's slow growth rate, however, some time will be needed for populations to return to their previous levels.
Goliath groupers are believed to be protogynous hermaphrodites, which refer to organisms that are born female and at some point in their lifespans change sex to male. Males can be sexually mature at about 115 centimeters (45 in), and ages 4–6 years.
In May 2015, the Atlantic Goliath grouper was successfully bred in captivity for the first time. Tidal pools act as nurseries for juvenile E. Tamara.
In tidal pools juvenile E.Tamara are able to utilize rocky crevices for shelter. Besides shelter, tidal pools provide E. Tamara with plenty of prey such as lobster and porcelain crab.
The Atlantic Goliath grouper has historically been referred to as the “Jewish”. It may have referred to the fish's status as inferior leading it to be declared only suitable for Jews, or the flesh having a “clean” taste comparable to kosher food ; it has also been suggested that this name is simply a corruption of jaw fish or the Italian word for “bottom fish “, Giuseppe.
In 2001, the American Fisheries Society stopped using the term because of complaints that it was culturally insensitive. Age, Growth, and Reproduction of Jewish Epimetheus Tamara in the Eastern Gulf of Mexico.

NOAA scientists from our Southeast Fisheries Science Center are monitoring the status and recovery of Goliath grouper. Its range includes the Gulf of Mexico and Florida Keys in the United States, the Bahamas, most of the Caribbean, and most of the Brazilian coast.
Scientists from our Southeast Fisheries Science Center are working to understand the changes that have occurred in coral reef ecosystems following the loss of top predators, such as groupers. From 1997-2005, our researchers collaborated with Florida State University's Institute for Fishery Resource Ecology (Dr. Chris Koenig and Dr. Felicia Coleman) to monitor the status and recovery of Goliath grouper.
This Goliath grouper research program investigated juvenile and adult Jewish abundance, distribution and migration patterns; their age and growth; and their habitat utilization. With the help of Don Maria we have tagged over 1,000 adult Jewish and have observed aggregations of Goliath grouper in both the Gulf of Mexico and more recently, the South Atlantic.
Posters created by the Center of Marine Conservation help disseminate information about our project and its requirements, highlighting our tagging study and the morphology of Goliath grouper. Given that these groupers were afforded protected status, researchers worked to utilize and develop novel non-lethal techniques to procure and analyze biological samples for life history information.
Researchers have also determined that soft dorsal rays hold promise for aging older fish (Marie et al., 2008). These casualties, resulting from red tide, gave our biologists a unique opportunity to collect a multitude of biological samples, without having to sacrifice healthy animals.
Tissue samples were also removed and sent to the Florida Marine Research Institute, so they could evaluate the level of red tide toxin. The sampling trip gave these biologists an opportunity to educate the curious beach goers about red tide and Goliath grouper (a few of which had been misidentified as baby manatees).
Attempts to evaluate the data needed to assess the status of these depleted stocks and develop rebuilding plans present unique challenges. In 2010, the Florida Fish and Wildlife Conservation Commission and NOAA Fisheries convened a benchmark Goliath grouper assessment for the continental U.S. population.
This project would not have been possible without ongoing collaboration with researchers from Florida State University, Everglades National Park, and the recreational fishing and SCUBA diving communities. Reading Time: 7minutesGroupers are some of Florida’s most iconic fish species.
From monster Goliath's to delicious Scamps, these big bottom-dwellers are a favorite on most Floridian fishing trips. In this article, you can learn all about the different types of Grouper in Florida.
The average catch in Florida is around half that length, weighing between 5 and 20 pounds. Black Grouper live around rocky bottoms and reefs on both sides of the Sunshine State.
They spend their summers spawning in much shallower seas, though, as little as 30 feet deep. Commonly known as “Grey Grouper,” these guys are a staple of reef fishing trips around the Gulf and up the Atlantic.
They don’t grow as big as Black Grouper, usually maxing out somewhere around 50 pounds. However, younger Gags can be found in estuaries and even seagrass beds, so don’t be surprised if you hook one while you’re on the hunt for Redfish and other inshore species.
Bigger fish hunt around muddy and rocky coastal waters. Young Goliath's will head right into estuaries and look for food around oyster bars.
Their huge size and fearless curiosity made them an easy target, and they were overfished almost to extinction in the late 20th century. Luckily, Goliath Grouper are strictly protected these days, and you can only fish for them on a catch-and-release basis.
From teaming up with other predators to catch their dinner to reportedly fanning bait out of traps for an easy snack, they’re far brighter than most people give them credit for. Sadly, this intelligence comes with the same natural curiosity that put Goliath Grouper in hot water.
If you come across one, count yourself lucky for the chance to meet it and make sure it swims off unharmed. Nothing says “reef fishing in Florida” like a boastful of big, tasty Red Grouper.
These deep-water hunters are the reason people bother to go offshore when there are so many fish in the shallows. The average Red Grouper weighs somewhere in the 5–10 lb range, and anything over 2 feet long is a rare catch.
They live around rocky bottom up to 1,000 feet down, so you may have to travel 20 miles or more to get to them. According to most people who have caught them, Scamp are the tastiest fish in the family.
You won’t come across them in much less than 100 feet of water, and you can easily find them in three or four times that depth. They also grow much bigger than Scamp, meaning you’re in for a real feast if you catch one.
If you’re set on landing a “Snowier,” get ready for a long ride. NOAA has declared Speckled Hind a Species of Concern, mainly because they have so little data on them.
If Goliath Grouper are the kings of the shallows, these guys dominate the deep. Add in the fact that they live several hundred feet down, where all fish taste great, and they become the dream catch of many deep dropping enthusiasts.
Their dappled, red body and bright yellow fins provide camouflage around the deep, rocky structure that they hunt around. Yellow fin’s scientific name, Mycteroperca Vanessa, roughly translates to “Poisonous Grouper.” This is because they tend to have very high levels of ciguatoxin.
They’re slightly smaller than Scamp on average, but many anglers say that they taste just as good. Yellow mouth Grouper are uncommon in the Gulf of Mexico, but you can bag yourself a colorful feast all along Florida’s Atlantic Coast.
Select fish and enter length in inches: This allows the pleasure of catching a fish, accurately determining its weight and then returning it to the ocean unharmed to live another day.
