Scientists estimate that historical overfishing decreased our numbers by about 80%, and it’s been a long road to recovery. After they’re fertilized, the eggs drift around in the currents until they finally hatch.
The Atlantic Goliath grouper or Tamara (Epimetheus Tamara), also known as the Jewish, is a large saltwater fish of the grouper family found primarily in shallow tropical waters among coral and artificial reefs at depths from 5 to 50 m (16 to 164 ft). 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 goliathgroupers 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.
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.

However, during reproduction (immediately after the full moons between June and December), they come together in groups of at least 100 individuals. These groups are known as spawning aggregations, and they form at relatively few places throughout the species’ range.
Though they were likely naturally rare, scientists believe that destructive fishing practices have reduced the numbers of the Atlantic goliathgroupers by at least 80% and that the species is now critically endangered. These fish utilize the same, few locations and same, few days for spawning every year, so their presence is quite predictable.
Furthermore, a total lack of fear of people makes them an easy target for spear fishers. Finally, the Atlantic Goliath grouper’s large size, slow growth, and ease of capture all contribute to slow its recovery, even where laws have been put in place to give it some or complete legal protection from fishing (e.g., in the USA and Brazil).
It is important to continue to monitor Atlantic Goliath grouper population trends in order to determine whether the species is recovering or if stronger legal protection may be required. Scientists only recently divided the species into two, based on their slightly different genetic makeup.
The two species are similar in both appearance and behavior, but little is known about the population trends or conservation status of the Pacific Goliath grouper. Somewhere in the warm waters off the Florida Keys lives a fish named Sylvia.
Fabien Cousteau named the distinctive Atlantic Goliath grouper after famed ocean scientist Sylvia Earle when the curious fish and her larger companion repeatedly visited Cousteau during his expedition in the undersea laboratory Aquarius off-Key Largo in 2014. “As ocean icons, it seemed normal that two beautiful goliathgroupers we saw almost every day would be named after my grandfather and Sylvia,” Cousteau says.
The arguments may sound plausible on the docks, but do not add up in the science lab, says Chris Koenig, a retired University of Florida marine biologist who has studied Goliath for decades. Koenig, whose fascination with goliathgroupers dates to his boyhood when the fish was considered worthless, and his wife, Florida State University scientist Felicia Coleman, posted a “fact or fiction” paper online to refute false claims and clarifying the groupers dining habits and biology.
Koenig says the push to lift the ban on catching Goliath grouper has more to do with sport than anything else. Among trophy fish caught in the Florida Keys, the Goliath grouper has long held special distinction.
None of the counts convinced officials to reopen the Goliath grouper fishery so far. “We don’t really know how low the population got right before the closure,” says Amanda Valley, the commission’s spokesperson.
Valley adds the commission has no plans on the horizon to the reconsider grouper’s status. Dan Maria, a commercial diver who used to hunt Goliath with a spear when they were plentiful, now thinks they are worth more alive than dead.
The experience becomes even more exotic during mating season, when Goliath migrate north to cooler waters just off Palm Beach, Florida, and gather in groups of 50. “Nowhere else in the world can you swim up to a fish that is the size of a small Volkswagen and pet it on the face and see about 30 of them around you,” he says.
He's finalizing a new analysis of the behemoth, in which he lays out a plan for reopening the juvenile Goliath grouper to fishing on a limited, sustainable basis. His data suggests this type of fishery may better protect the Goliath in the end.
Growing to lengths of 8.2 feet (2.5 m), this grouper can weigh as much as 800 pounds (363 kg). In Florida, the largest hook and line captured specimen weighed 680 pounds (309 kg).
And since they’re illegal to keep, not many people want to tug on a 500-pound fish for upward of an hour just to release it. They are relatively slow growing and take five to seven years to reach sexual maturity.
Large groupers in the Caribbean are linked to increased risk of Cautery poisoning. Growing to lengths of 8.2 feet (2.5 m), this grouper can weigh as much as 800 pounds (363 kg).
In Florida, the largest hook and line captured specimen weighed 680 pounds (309 kg). Since 1990, it has been illegal to capture or kill the Goliath in federal and state waters.
However, for several years, fishermen in Florida have contested that the grouper are back, and are eating much of their catch. The mysterious animal that had killed and eaten the 9-foot great white shark and had stumped scientists turned out to be a super predator feared by even apex predators like the great white shark.
Grouper is a lean, moist fish with a distinctive yet mild flavor, large flakes and a firm texture. Grouper’s flavor profile is like a cross between Bass and Halibut.
Goliath groupers eat crustaceans, other fish, octopuses, young sea turtles, sharks, and barracudas. The Goliath grouper, which, according to BMNH, has been known to stalk humans and “conduct unsuccessful ambushes,” took off with Saber’s spear and gun trailing behind.
“ Goliath grouper teeth are small and recurred,” Koenig said. “They are designed to hold the fish within the mouth cavity, not to cut it in pieces.
In most all cases, these Goliath Grouper are even more aggressive eaters than sharks when they attack prey. And this video by Blackish is pretty clear evidence of just how quick and aggressive these large GoliathGroupers are when it comes to getting a meal.
Chimeras, also called ghost sharks or catfish, belong to the Elasmobranchii family but are more distantly related to the rest of the group. Shook meat is white with a medium firmness, not as delicate as trout but not as dense as swordfish.
All young yellow mouth groupers (Mycteroperca interstitial is) are born females, but as they grow larger they change into males. Only small percentages survive long enough to become a male, thus ensuring the greater majority are egg-laying females.
White perch is a favorite for its flaky textured meat. 6 of the Healthiest Fish to Eat (And 6 to Avoid) It’s both delicious and nutritious, as fish are a source of lean protein and omega-3 fatty acids that benefit your heart and brain.
Good choices are safe to eat one serving a week. Fish to avoid shouldn’t be eaten at all because they have the highest mercury levels.
They include King mackerel, marlin, shark, and swordfish. Salmon farming is significant in Chile, Norway, Scotland, Canada and the Fare Islands; it is the source for most salmon consumed in the United States and Europe.
Atlantic salmon are also, in very small volumes, farmed in Russia and Tasmania, Australia. Only one percent of the world fishing fleet is larger than 100 gross tons (longer than 24 meters).
