The knobbed porgy (Calamus nodosus) is an ocean-going species of gamefish of the bream/porgy family, Sparidae. They are only found in the western portion of the tropical Atlantic Ocean, where they are often caught with trawling nets or by angling, and used as food. [2] The knobbed porgy was named by John Randall and David K. Caldwell as part of a 1966 review of the genus Calamus, which was published in the academic journal Science . [3] Randall and Caldwell also described three other species of Calamus in the paper. [3]
Knobbed porgies have a fairly deep body with a steep profile, and a nape that projects noticeably in larger adults, later developing into a humped 'forehead'. [4] They are similar in coloration to the littlehead porgy, with silver to brass bodies with a rosy cast and violet snouts and cheeks. Knobbed porgies can be distinguished by blue lines present on a yellowish under color. [4]
The longest knobbed porgy ever caught was recorded at 54.4 cm, [5] though adults on average will grow to around 35 cm. [6] Able to live as long as 17 years, [5] Knobbed porgies have been recorded to weigh up to 2.63 kg. [7] Like many other members of the Teleost infraclass, knobbed porgies are sequential hermaphrodites—they are born female, and become males over their lifetimes. [5] In this case, knobbed porgies experience sex change when they reach mature lengths of 30–50 cm. [5]
In the western Atlantic Ocean, the knobbed porgy is known from the coast of North Carolina south to eastern Florida and the entire Gulf of Mexico including the coast of Cuba and the Campeche bank. [8] It is found over hard bottoms at depths from 7 to 90m, and can also be associated with ledges, coral reefs, [2] and near-by areas of gravel, grass or sand. [4] Knobbed porgies are carnivorous, and feed primarily on mollusks, polychaetes, crabs, and sea urchins. [5]
Calamus is a genus of marine ray-finned fishes belonging to the family Sparidae, the seabreams and porgies. Most of the species in this genus are found in the Western Atlantic Ocean, with 2 species occurring in the Eastern Pacific Ocean.
The gafftopsail catfish is a species of marine catfish found in the waters of the western central Atlantic Ocean, as well as the Gulf of Mexico and the Caribbean Sea. It has long, venomous spines which can cause painful wounds. It feeds on crustaceans and other fish. The male of the species fertilizes the eggs of the female, and broods them in his mouth until they hatch. The gafftopsail feeds throughout the water column. This fish is a common catch in the Southeastern US, although it may be found as far north as New York. They are considered strong fighters by anglers. They are taken from piers, jetties, reefs, and the surf, as well as bottom fishing or flats fishing. They are caught with hard lures as well as soft plastics, cut bait, and live or dead shrimp. Some fishermen use traps for catfish, a method regulated by some states.
The yellowfin grouper is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It is found in the warmer waters of the western Atlantic Ocean.
The slippery dick is a species of wrasse native to shallow, tropical waters of the western Atlantic Ocean.
Caranx lugubris, the black jack, black trevally, black kingfish, coal fish or black ulua, is a species of large ocean fish in the jack family Carangidae. The species has a circumtropical distribution, found in oceanic, offshore waters of the tropical zones of the Pacific, Atlantic and Indian Oceans. The species is particularly prevalent around offshore islands such as the Caribbean islands in the Atlantic, Hawaii and French Polynesia in the Pacific and the Seychelles and Maldives in the Indian Ocean. Black jack are rare in shallow waters, preferring deep reefs, ledges and seamounts in clear waters. The species is easily distinguished by its black to grey fins and jet black scutes, with the head having a steep profile near the snout. The largest recorded length is 1 m and weight of 17.9 kg. The black jack lives either individually or in small schools, and is known to school with other species. It is a predatory fish, taking a variety of fish, crustaceans and molluscs as prey. Sexual maturity is reached at 34.6 cm in females and 38.2 cm in males, with spawning taking place between February and September in the Caribbean. The early life history of the species is very poorly understood. Black jack are of high importance to many island fisheries, but are rarely encountered in most continental fisheries. The species has a reputation as a gamefish, and is variably considered a terrible or excellent food fish, although several cases of ciguatera poisoning have been attributed to the species. The species was initially named Caranx ascensionis by Georges Cuvier, however several issues with the use of this name have seen Felipe Poey's name Caranx lugubris become the valid scientific name.
Trachinotus goodei, the palometa, is an ocean-going game fish of the family Carangidae. Other common names include banner pompano, camade fish, cobbler, gafftopsail, great pompano, joefish, longfin pompano, old wife, sand mackerel, streamers jack, wireback. This fish is native to the western Atlantic Ocean from Massachusetts to Bermuda to Argentina. It can be found in the Gulf of Mexico and the Caribbean Sea.
The lookdown is a species of game fish in the family Carangidae. It was first described in 1758 by Carl Linnaeus, in the 10th edition of Systema Naturae.
The sheepshead porgy, also known as the littlemouth porgy or speckled porgy, is a species of marine ray-finned fish belonging to the family Sparidae, the seabreams and porgies. This species is found in the Western Atlantic Ocean.
Gymnothorax miliaris, the goldentail moray, bastard eel, or conger moray, is a species of marine fish in the family Muraenidae.
The flat needlefish, or barred longtom, the only known member of the genus Ablennes, is a marine fish of the family Belonidae. Flat needlefish are considered gamefish, frequently caught with the help of artificial lights, but are not often eaten because of their green-colored flesh.
Haemulon vittatum, the boga, is an ocean-going species of grunt native to the western Atlantic Ocean. Bogas are also known as the snit in Jamaica, and bonnetmouth in the Bahamas. It was first described by Cuban zoologist Felipe Poey. This species used to be classified as Inermia vittata, but genetic data revealed that it belongs to the genus Haemulon.
Emmelichthyops atlanticus, the bonnetmouth, is a marine fish species of grunt native to the western Atlantic Ocean, where it occurs from Florida and the Bahamas to northern South America. This species is the only known member of its genus.
Western Atlantic seabream is an ocean-going species of fish in the family, Sparidae. It was first described in 1758 by the "father of modern taxonomy," Carl Linnaeus, in the 10th edition of his book, Systema Naturae. Within their native range, Western Atlantic seabream are also known as the seabream, brim, tropical sheepshead, chopa amarilla, or salema. Although they are eaten, and have been described as pan fish, Western Atlantic seabream have not gained the popularity as a gamefish that their relative, the sheepshead has.
The saucereye porgy is an ocean-going species of fish in the family Sparidae. In Bermuda, they are also known as the goat's head porgy. In Jamaica, they are known as the Porgi grunt and the sugareye porgy. They may also be known simply by the name Porgy in several other Caribbean islands. Saucereye porgies are considered to be minor gamefishes and when caught are marketed both fresh and frozen.
