Groupers are generally a friendly species and can be found patrolling artificial and coral reefs alike, primarily in shallow tropical waters. Goliath groupers navigate to an annual spawning for breeding, the season and location varies depending on the population.

In Florida, hatchlings join their brethren in safe spaces near coastal mangrove estuaries and spend their first six years of life dining exclusively on fish, crabs, and shrimp before heading out to open waters. The Goliath grouper grows slowly, attaining maturity around age 20-25, which is why it is important to manage fishing of the species; they need the chance to reach adulthood to reproduce in order to create a sustainable fishery.

The Goliath grouper is a key species in Florida waters because their presence is an indicator of health for local coral reefs. This particular species feeds by swallowing their prey whole, creating negative pressure that quickly them to bring in whole invertebrates, fish, and even smaller sharks.

Many grouper, manatees, and turtles were found washed ashore on Southwest Florida beaches during the red tides in 2003 and 2005. The good news is that as of 2006 the Goliath grouper ’s population had improved and was considered to be on a recovery trajectory due to the careful protection by NOAA Fisheries.

Which, along with their size, made them a prime target for fishmongers and caused their population to drastically decrease, so much so that in 1990 the US had to put a harvest ban on the species with the Caribbean following suit in 1993, and Brazil in 2002. And while this means throughout most of the year the numbers of Goliath groupers sticking together in any one place is quite low, they are still easy targets due to the way they reproduce.

When the time to reproduce comes, Goliath groupers come together in large groups that are rarely made up of less than a hundred individuals. In other words, the Goliath groupers utilize the same few places and same few days a year to spawn, which makes them predictable, and thus, easy targets for fisherman looking to catch them.

You’ll only need fresh and cleaned grouper fillets, a lemon, and an Italian seasoning mix along with some salt and pepper. Put a generous amount of salt and pepper on both sides of the fish, lay the fillets out on the foil drizzled with olive oil, and sprinkle Italian seasoning on top.

Rub salt and pepper over the fillets, lightly dust with flour, and fry in butter and olive oil (yes, both) for 3-4 minutes on each side. Squeeze some lemon over it when you flip the fish (be careful because the juice will start bubbling when it hits the heat).

In the western Atlantic Ocean goliathgrouper are found from Florida to Brazil, including the Gulf of Mexico and the Caribbean Sea. In the Eastern Atlantic they occurred from Senegal south to the Congo; however, this population is believed to have been eliminated because no individuals have been observed there for many years.

The species has since been protected in Brazil (2002), Puerto Rico (2004) and the U.S. Virgin Islands (2004), but fishing continues in other parts of its range. Following the granting of protected species status, abundance in Florida has appeared to increase over the past two decades, but the extent of the recovery is not clearly understood.

Likewise, information on the perceived increase in abundance is limited, and it is difficult for fisheries managers to truly understand the extent to which the species has recovered throughout its geographic range. This perception is reinforced by the fact that goliathgrouper will opportunistically prey upon hooked or speared fish.

Many anglers and divers are now concerned that the goliathgrouper ’s protected status has resulted in abundance levels that do not represent a natural ecosystem balance. Adult Goliath groupers are generally sedentary and have small home ranges, making them more vulnerable to spearfishing.

The fact that they form predictable spawning aggregations further increases susceptibility to fishing pressure. Goliath grouper are dispersal spawners, meaning eggs and sperm are released and mixed in the water column during spawning.

Juveniles settle in shallow estuaries habitats, where they reside for several years before moving offshore. Juveniles remain in mangrove habitat for the first five to six years of life, and then move offshore when they reach about 3 feet.

Abundant food and shelter result in high survival and fairly rapid growth of 4.5-6 inches per year during the juvenile phase. As with juveniles, adult Goliath groupers also have a tendency to remain at one site for extended periods.

Juveniles moving out of mangrove habitat may disperse far and wide until they establish a more permanent home range. One juvenile tagged in the Ten A Thousand Islands was recaptured on the central east coast in the Indian River area.

To date, goliathgrouper stomach content analysis has documented that about 85% of their diet consists of crustaceans, mostly crabs. This measures the relative concentration of certain molecules like oxygen and carbon in body tissue to help scientists understand links in the marine food web.

Results show that Goliath groupers occupy a relatively low position on the food chain, about on the same level as the tiny pinkish, a common bait fish. However, the perception that goliathgrouper are consuming healthy groupers and snappers is not supported by scientific evidence.

Consequently, the number of goliathgrouper observed concentrated over structure during the day may not represent all that are actually present. Since protective measures were implemented in 1990, anecdotal accounts and directed research efforts indicate increasing abundance of goliathgrouper throughout Florida.

The most recent stock assessment (2004) indicated that goliathgrouper in Florida waters were recovering, but that the population may not experience full recovery until 2020 or later. Because the harvest of goliathgrouper is prohibited, the conclusions of the stock assessment were made in the absence of certain types of biological information (e.g., age structure, sex ratio) that are typically available for other species through the examination of harvested individuals.

Citizen volunteers have played an important role in assessing Goliath grouper abundance and locating spawning aggregations. Although useful, these data do not consistently include size distribution or standardized sampling throughout seasons.

Everglades National Park Angler Surveys: Detailed catch and effort data collected during volunteer dockside interviews of recreational anglers from within Everglades National Park show a substantial decline in abundance during the late 1970s and early 1980s. Since the moratorium in 1990, the abundance of juveniles within ENP, which includes critical nursery habitat for this species, has increased considerably.

Anglers and divers can provide valuable assistance by reporting observations of tagged Goliath grouper (see information below). Citizen volunteers have played an important role in helping scientists evaluate the recovery of goliathgrouper and also in identifying spawning aggregations.

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 goliathgrouper 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. This makes them particularly vulnerable to mass harvesting while breeding.

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 goliathgrouper 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 goliathgrouper 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.
