Myctoperca Monaco has an oblong, literally compressed body with a standard length which is 3.3 to 3.5 times its depth. It has an evenly rounded properly with no incisions or lobes at its angle.
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).

U.S. wild-caught black grouper is a smart seafood choice because it is sustainably managed and responsibly harvested under U.S. regulations. Fishing gears used to harvest black grouper have minimal impacts on habitat.
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.
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.
The blacktop grouper (Epimetheus fascists), also known as the red banded grouper, blacktopped cod, black -tipped rock cod, footballer cod, red-barred cod, red-barred rock cod, scarlet rock-cod or weathered rock-cod, is a species of marine ray-finned fish, a grouper from the subfamilyEpinephelinae which is part of the familySerranidae, which also includes the antics and sea basses. It is found in the tropical Indo-Pacific region.
It is the type species of the genus Epimetheus. The blacktop grouper has a body which has a standard length which is around 2.8 to 3.3 times its depth.
The area between the yes is flat but the dorsal profile of the head is convex. The rounded properly has a finely serrated rear margin with he the lowest serrations slightly enlarged.
The upper edge of the gill cover is straight. The dorsal fin contains 11 spines and 15-17 soft rays while the anal fin has 3 spines and 8 soft rays.
The color is variable and ranges from pale greenish gray to pale reddish yellow to scarlet. They frequently have 5 or 6 faint dark bars, the final one being on the caudal peduncle.
The scales on the upper body have a pale center and dark rear margin, which creates am indistinct checked pattern. The outer membrane of the spiny part of the dorsal fin is black, or dark red in specimens from Western Australia and some from deep water.
There is a pale yellow or white spot to the rear of the tip of each of the dorsal fin spines. This species attains a maximum total length of 40 centimeters (16 in), although a more common length is around 22 centimeters (8.7 in), and a weight of 2.0 kilograms (4.4 lb).
This species may present simultaneous Hermaphroditus in smaller individuals, while the large individuals usually lose female function. Blacktop groupers are host of several parasites, including Pseudorhabdosynochus SPP.
The filmstrip nematode Philomath fascia ti is parasitic in the ovary of female fish; the adult female parasite is a red worm which can reach up to 40 centimeters in length, for a diameter of only 1.6 millimeter; the males are tiny. Raphidascaris (Ichthyascaris) fascia ti is a nematode parasitic in the intestine, 20 mm in length, described in 2020 and named after the fish.
