Reefs are considered healthier if you see one of us swimming around because we help maintain balance in the ecosystem. I use my large mouth to suck in whole fish or invertebrates, then swallow them right away.

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.

Müller & Trochee, 1848 Serra nus guava Play, 1860 Promiscuous one Ehrenberg, 1915 Promiscuous ditto Roux & Collision, 1954 The Atlantic goliathgrouper 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 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.

Wikimedia Commons has media related to Epimetheus Tamara. The giant of the grouper family, the Goliath (formerly called Jewish) has brown or yellow mottling with small black spots on the head and fins, a large mouth with jawbones that extend well past its small eyes, and a rounded tail.

The skeletal structure of large Goliath grouper cannot adequately support their weight out of the water without some type of damage. If a large Goliath is brought on-board a vessel or out of the water, it is likely to sustain some form of internal injury and therefore be considered harvested.

Goliath grouper populations declined throughout their range during the 1970s and 1980s due to increased fishing pressure from commercial and recreational fishers and divers. At their July 2014 meeting in Key Largo, this committee reviewed the most up-to-date scientific information on goliathgrouper and recommended a new stock assessment for this species.

As a result, the most recent stock assessment, conducted by the FCC was completed in June 2016 (Sedan 47). The stock assessment indicates abundance in south Florida has greatly increased since the fishery closed in 1990.

However, in the final step of the review process, the assessment was rejected by an independent panel of scientists for use in federal management due to a lack of reliable indicators of abundance outside south Florida. Goliath are also susceptible to large scale mortality events such as cold temperatures and red tide blooms.

When not feeding or spawning, adult Goliath groupers are generally solitary, sedentary and territorial. Before the goliathgrouper reaches full-size it is preyed upon by barracuda, king mackerel and moray eels, as well as sandbar and hammerhead sharks.

Calico crabs make up the majority of their diet, with other invertebrate species and fish filling in the rest. Reproductive maturity first occurs in fish 5 or 6 years of age (about 36 inches in length) due to their slow growth rate.

Males mature at a smaller size (about 42 inches) and slightly younger age than females. These groups occur at consistent sites such as wrecks, rock ledges and isolated patch reefs during July, August and September.

Studies have shown fish may move up to 62 miles (100 km) from inshore reefs to these spawning sites. In southwest Florida, presumed courtship behavior has been observed during the full moons in August and September.

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.
