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.

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.

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.

From these decomposing carcasses, biologists were able to record length for use in an age/length relationship, and were able to extract monoliths and remove dorsal spines and rays for comparison of hard parts in age and growth analysis. 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.

I learned about it from a buddy diver who excitedly told me to go diving with him upon a prompt from a classmate in high school who happened to be the mayor of that town. Probably, I am lucky that the Goliath grouper (Epimetheus quinquefasciatus) I encountered several minutes when I plunged into the water was still a juvenile.

I brought with me my automatic Nikon camera encased in a plastic casing to make it water-resistant as taking pictures is a pleasure for me each time I travel. I grabbed the camera hanging by a tough nylon string around my wrist, and took a video of the Goliath grouper following my buddy.

Despite the huge size of the Goliath grouper, they seem to be docile fishes although there are reports that they do attack humans. I saw one video that says so but analyzing the situation, I thought the reason was mainly to feed, not really to attack.

The moving fins attracted the grouper thinking probably that it was its prey and snapped on it. When the juveniles are older, they migrate to the coral reefs and stay there for more than 40 years.

After being hunted to endangered status, Goliath grouper have been one of the biggest headaches for anglers with their aggressive nature and hungry appetite eating hook fish on popular spots. Florida's anglers fishing larger structures like shipwrecks, artificial reefs or natural sinkholes are well aware that Goliath prowl below.

Goliath's have recently been targeted for catch and release by anglers inside Tampa Bay around the Sunshine Skyway and markers. His 8500 Penn Spin fisher and 12-foot surf rod were loaded with 65-pound Power Pro and heavy 125-pound leader ready for a toothy shark.

Then I felt a tap like it was free, and I slammed the hook and horsed her out while she kept trying to run back to the structure!” After a brief tug of war Ruse saw the shadow through the water and realized it was a smaller Goliath grouper, a true surprise to him and where he was fishing.

He removed the hook and took a few brief pictures while leaving the grouper in the water which was made easier by the slope of the beach.
