The groupers complex is not subject to overfishing based on 2019 catch data. Black grouper grow up to five feet long and can weigh up to 180 pounds.

Black grouper take advantage of other species’ reproductive aggregations for feeding. They are particularly associated with the southern Gulf of Mexico, Florida Keys, Cuba, the Bahamas, and throughout the Caribbean.

Annual catch limits are used for black grouper in the commercial and recreational fisheries. These fisheries are closed when their annual catch limit is projected to be met.

Both the commercial and recreational fisheries have size limits to reduce harvest of immature black grouper. The commercial and recreational fishing seasons are closed from January through April to protect black grouper during their peak spawning period.

Minimum size limits protect immature black grouper. Year-round and/or seasonal area closures for commercial and recreational sectors to protect spawning groupers.

Groupers are managed separately by commercial and recreational sector in Puerto Rico. Seasonal closure for black, red, tiger, yellow fin, and yellow edge groupers from February 1 through April 30.

Similar Species: Gag, M. microbes (spur on properly is serrated); and yellow fin grouper, M. Vanessa (pectoral fins trimmed in bright yellow) Adults are associated with rocky bottoms, reef, and drop off walls in water over 60 feet deep.

They are protogynous hermaphrodites, meaning that young predominantly female who transform into males as they grow larger. Larger individuals of this species are generally found in greater depths, and they feed on fish and squid.

The caudal fin is truncate to marginate, although it may be convex if spread widely. This species has an overall t’s an olive gray color and is marked with dark blotches and brassy hexagonal spots over the head and flanks.

This fish attains a maximum total length of 150 centimeters (59 in), although they are more common at around 70 centimeters (28 in) and a maximum published weight of 100 kilograms (220 lb). Mycteroperca Monaco occurs over rocky bottoms and coral reefs at depths of 10 to 30 meters (33 to 98 ft), however in the eastern Gulf of Mexico it is normally encountered at depths of more than 30 meters (98 ft).

It is usually a solitary species, the adults feeding mainly on fishes, such as grunts, snapper and herrings, and the juveniles feed on crustaceans. Black groupers have been recorded forming seasonal feeding aggregations along the outer continental shelf off Brazil, these coincide with spawning aggregations of some fish species the groupers prey on.

They are is a monastic protogynous hermaphrodites, and they form spawning aggregations and these have been reported from in the Gulf of Mexico and Caribbean Sea. Females attain sexual maturity at around 5years old and at a length of around 82.6 centimeters (32.5 in) and the change of sex to males occurs when they are around 15 years old and at a mean length of 121.4 centimeters (47.8 in).

It has an ob longed body shape and rounded margins on both the dorsal and anal fins. The preopercule is rounded without the presence of a notch, which distinguishes it from the gag grouper (Mycteroperca microbes).

The black grouper has olive or gray body coloration along with dark rectangular blotches and small hexagonal bronze spots on its head and lower side. Adult black grouper feed primarily on other smaller reef fishes, including grunts, snapper, and herrings.

The meat generates a fairly high price and is considered very good quality. Black groupers can reach up to 52 inches (133 cm) in length and can weigh up to 179 pounds (81 kg).

It is also present in the Gulf of Mexico and the Caribbean Sea, including the Florida Keys and Cuba. Black groupers typically have dark coloration, with olive, gray or brown bodies and irregular bronze-colored blotches and spots.

Spotted black groupers are large, territorial reef fishes that can reach 2 m in length and at least 80 kg, although most seen in New Zealand are considerably smaller than this. Spotted black grouper (Epimetheus Amelia) are known as black cod, saddled rock cod and saddle tail grouper in Australia.

Spotted black grouper are true groupers belonging to the family Serranidae, subfamily Epinephrine. Although commonly called ‘groper’ in New Zealand, the haiku (Poly prion oxygenate) and bass (P. Americans) are actually ‘wreck fishes’ belonging to the family Polyprionidae.

Spotted black grouper are only found in southeast Australia (Spencer Gulf to southern Queensland, excluding Tasmania), Elizabeth and Middleton Reefs, Lord Howe and Norfolk Islands, and northern New Zealand. In New Zealand the largest and possibly only breeding population is found in the Germanic Islands Marine Reserve.

Around mainland New Zealand spotted black grouper are relatively common on shallow reefs at Three Kings Islands and along Northland’s rocky east coast. Small juveniles have been recorded as far south as Dominika on the west coast, and Palmier Bay in the east.

Spotted black grouper inhabit rocky reefs in estuaries and on the open coast to at least 50 m depth. At the Germanic Islands small juvenile spotted black grouper are found in large intertidal rock pools as well as amongst boulders at 20 to 30 m depth.

Spotted black grouper appear to have had very little fishing pressure anywhere in New Zealand, however those in eastern Australia are considered to be heavily depleted by line, set net and spear fishers. Spotted black grouper are opportunistic predators of smaller reef fishes and crustaceans (shrimps, crabs and rock lobster).

Spotted black grouper are vulnerable to a variety of fishing methods due to their large size, territorial behavior and natural curiosity. Populations in eastern Australia are considered to be overfished and their estuaries nursery habitats are threatened by coastal development and pollution.

Spotted black groupers may suffer internal damage from hooks and over-expansion of their swim bladder if caught by accident. Like whales, large filter-feeding sharks and rays can accidentally ingest these, and all species suffer from entanglement in marine debris.

They also have teeth plates inside their throat that prevent prey from escaping after being swallowed. Species Habitat Black grouper are found in the western Atlantic Ocean with ranges extending from Massachusetts to Brazil.

Occurrences of the species north of Carolina's are considered to be rare and most likely due to larval transport in the Gulf Stream rather than migration. Juveniles can occur in seagrass and oyster rubble habitat in the Carolina's, and along reefs in the Florida Keys and in Brazil.

Adults prefer rocky bottoms, drop-off walls and ledges, caves, crevices, and coral and artificial reefs. While they are relatively sedentary and can remain in one particular site for some time, black grouper move to progressively deeper waters as they age.

They used passive acoustic recorders to monitor sound production indicative of spawning habitat use by groupers at Riley’s Hump in the Tortuga's South Ecological Reserve in Florida, the first known US spawning site for black grouper. This study illustrated the importance of the Tortuga's South Ecological Reserve and called for continued research in order to understand its role in the recovery and sustainability of managed fish populations.

Because of the vulnerability to overfishing associated with large aggregations and the biodiversity therein, it is important to consider spawning locations in the establishment of marine protected areas and seasonal closures. Limiting the number of available permits (both transferable and nontransferable) available to commercial fishers; Establishing annual catch limits for both commercial and recreational fishers; Establishing overall species quotas; Commercial and recreational size limits to reduce harvest of immature grouper ; Seasonal closures to protect spawning aggregations; Gear restrictions to protect habitat and reduce by catch; and, Eight deep-water marine protected areas closed to fishing and possession of snapper and grouper.

Established in 1984, the Reef Fish FMP and its amendments were designed to end historic overfishing for shallow water groupers and to rebuild populations. Establishes and allocates annual species-specific catch limits between commercial and recreational fishers for groupers and tile fish; Sets gear restrictions; Sets minimum size restrictions to protect immature grouper ; and, Establishes year round and seasonal area closures for both commercial and recreational fishers to protect spawning stock and essential fish habitat.

The If program allocates shares of the total commercial catch limit amongst individual fishers. Under the program, each fisher owns a share of the quota and can choose to fish it at anytime during the open season.

Strict commercial reporting requirements prevent fishers from harvesting more than their individual allocation. Red and black grouper are among the most important species caught in Mexico in terms of volume and economic value.

Most grouper, particularly those caught in the Mexican industrial bottom longline fishery, is imported to the US. Numerous entities are involved to some degree with creating, implementing, and enforcing fishery management strategies in Mexico.

Under SAGA RPA, the National Aquaculture and Fishing Commission (Coalesce) is charged with developing and carrying out fisheries management regulations. Wild Black grouper are found in the Atlantic from Massachusetts to Brazil, including the Gulf of Mexico.

Unlike red grouper, black grouper in the United States is considered to be one stock across both the South Atlantic and Gulf of Mexico regions. Grouper in generally are fairly long-lived and come together to spawn in large numbers, characteristics that make them vulnerable to fishing pressure.

A May 2014 Seafood Watch report stated that according to the most recent stock assessment in 2010, black grouper is not considered overfished. Grouper fisheries have high impacts on nontarget species, the Monterey Bay Aquarium reported.

The black grouper fisheries use hooking devices and circle hooks to reduce by catch. Venting tools are also employed to make it easier for reef fish to survive when released.

Management measures include permits, annual catch limits, fishing quotas, marine protected areas that are closed to fishing, seasonal closures, gear restrictions, minimum size limits, and data reporting requirements.
