Jack mackerels or saurels [2] are marine ray-finned fish in the genus Trachurus of the family Carangidae. The name of the genus derives from the Greek words trachys ("rough") and oura ("tail"). Some species, such as T. murphyi, are harvested in purse seine nets, and overfishing (harvesting beyond sustainable levels) has sometimes occurred. [5]
It is often used in Japanese cuisine, where it is called aji, in Turkish cuisine, where it is called istavrit, and in Portuguese Cuisine, where it is called carapau.
The genus Trachurus was defined in 1810 by Constantine Samuel Rafinesque-Schmaltz, who called the type species Trachurus saurus. Taxonomists later determined that T. saurus was in fact the same species as one described earlier as Scomber trachurus, defined in 1758 by Carl Linnaeus. Under the rules of binomial nomenclature, that species is now known as Trachurus trachurus , commonly known as the Atlantic horse mackerel.
The currently recognized species in this genus are: [6]

Mackerel is a common name applied to a number of different species of pelagic fish, mostly from the family Scombridae. They are found in both temperate and tropical seas, mostly living along the coast or offshore in the oceanic environment.
Horse mackerel is a vague vernacular term for a range of species of fish throughout the English-speaking world. It is commonly applied to pelagic fishes, especially of the Carangidae family, most commonly those of the genera Trachurus or Caranx. Species known as "horse mackerel" in one English dialect or another include:
The Carangidae are a family of ray-finned fish that includes the jacks, pompanos, jack mackerels, runners, trevallies, and scads. It is the largest of the six families included within the order Carangiformes. Some authorities classify it as the only family within that order but molecular and anatomical studies indicate that there is a close relationship between this family and the five former Perciform families which make up the Carangiformes.
The Atlantic horse mackerel, also known as the European horse mackerel or common scad, is a species of jack mackerel in the family Carangidae, which includes the jacks, pompanos and trevallies. It is found in the eastern Atlantic Ocean off Europe and Africa and into the south-eastern Indian Ocean. It is an important species in commercial fisheries and is listed as a Vulnerable species on The IUCN Red List of Threatened Species.
The leatherjacket fish, also known as leather jack, is a species of jack in the family Carangidae. Leather jack may also refer to other members of the Carangidae, such as the pilot fish. The largest are about a foot long.
The Pacific jack mackerel, also known as the Californian jack mackerel or simply jack mackerel, is an abundant species of pelagic marine fish in the jack family, Carangidae. It is distributed along the western coast of North America, ranging from Alaska in the north to the Gulf of California in the south, inhabiting both offshore and inshore environments. The Pacific jack mackerel is a moderately large fish, growing to a maximum recorded length of 81 cm, although commonly seen below 55 cm. It is very similar in appearance to other members of its genus, Trachurus, especially T. murphyi, which was once thought to be a subspecies of T. symmetricus, and inhabits waters further south. Pacific jack mackerel travel in large schools, ranging up to 600 miles offshore and to depths of 400 m, generally moving through the upper part of the water column.
Alectis is a genus of fish in the family Carangidae containing three extant species, all of which are large marine fishes. They are commonly known as threadfish, diamond trevallies or pompanos, although they have no close affiliation with the true pompano genus.
Alepes is a genus containing five extant species of tropical marine fishes in the jack family, Carangidae. They are commonly known as scads, a term applied to many genera of carangid fishes. Their body form, however, differs from these other scads by being much more ovate in shape, more similar to the larger jacks taken as game fish, although scads are generally much smaller. They are found in coastal waters throughout the Indo-West Pacific region.
The yellowtail scad, is an abundant species of small inshore marine fish of the jack family, Carangidae. The species is widespread in the Indo-Pacific region from east Africa in the west to Hawaii in the east, extending north to Japan and south to Australia. The yellowtail scad is the only member of the monotypic genus Atule and is distinguished from similar species by a well-developed adipose eyelid and finlet-like extensions of the last rays of the dorsal and anal fins. It inhabits coastal areas such as bays and coral reefs, preying on small fishes and crustaceans. Spawning has been well studied in Hawaii, where fish enter bays to spawn, releasing up to 161,000 eggs each between March and October. The yellowtail scad is an important component of fisheries throughout its range, taken by a number of netting and hook-and-line methods. It is a prized food fish in some regions and is cooked or preserved by a variety of methods.
Carangoides is a genus of tropical to subtropical marine fishes in the jack family, Carangidae. They are small- to large-sized, deep-bodied fish characterised by a certain gill raker and jaw morphology, often appearing very similar to jacks in the genus Caranx. They inhabit the subtropical and tropical regions of the Indian, Pacific, and Atlantic Oceans, often occupying coastal areas, including reefs, bays, and estuaries, rarely venturing far offshore. They are all predatory fishes, taking a variety of smaller fishes, crustaceans and cephalopods as prey. The genus was first erected in 1851 by Pieter Bleeker for an unknown taxon and currently contains 20 species. Many make up significant proportions of various fisheries, although a number of ciguatera cases have been attributed to them.
The false scad, also known as the spotfin scad, ten-finned horse mackerel and yellow horse mackerel, is a species of medium-sized marine fish classified in the jack family Carangidae. The false scad is distributed throughout the tropical and temperate waters of the eastern Atlantic Ocean from Namibia in the south to Spain and throughout most of the Mediterranean in the north. The species has an atypical body form compared to other species of Caranx, and can be distinguished from these on its elongate 'scad-like' body shape alone. Distinguishing the species from members of Decapterus and Trachurus is more difficult, requiring detailed anatomical analysis. The false scad is known to grow to a length of 60 cm and a weight of 1 kg. The species lives both pelagically and demersally in continental shelf waters, ranging from depths of 15 to 200 m. It is a predatory fish, taking small fishes, crustaceans including euphausiids and shrimps, and cephalopods as its main prey, with significant dietary shifts as it ages. The false scad reaches sexual maturity at 2 years of age, with spawning occurring between April and July in shallow inshore waters, where the juveniles remain. The species is of major importance to fisheries throughout its range, but particularly from Morocco to Senegal, with annual catches ranging from 500 to 19000 t. The species is caught using trawls, seine nets and gill nets and sold fresh, frozen or salted.
The Mediterranean horse mackerel, also known as the Black Sea horse mackerel, horse mackerel, Mediterranean scad, common scad, or simply scad, is a species of mackerel in the family Carangidae found in the eastern Atlantic from Bay of Biscay to Mauritania, including the Mediterranean Sea. It is a benthopelagic, subtropical, marine fish that can reach up to 60 cm (24 in) in length. In the countries near the Mediterranean and Black Seas, it makes up a significant portion of fish catch, 54% of fish caught in the latter. Despite overfishing in the 1980s, catch numbers have leveled out and it is listed as least concern by the International Union for Conservation of Nature.
The Chilean jack mackerel, sometimes called the Jurel, Inca scad or Peruvian jack mackerel, is a species of jack mackerel in the genus Trachurus of the family Carangidae. Since the 1970s, it has become one of the world's more important commercial fish species. High volumes have been harvested, but the fishery may now be in danger of collapsing.
The Japanese jack mackerel, also known as the Japanese horse mackerel or Japanese scad, is a species named after its resemblance to mackerel but which is in the family Carangidae, the jacks, pompanos, trevallies and scads. Their maximum reported length is 50 cm (20 in) with a common length of 35 cm (14 in). They have a maximum reported weight of 0.66 kg (1.5 lb) and a maximum reported age of 12 years. They are found around the coast of Japan, except Okinawa Island, usually on sandy bottoms of 50–275 m (164–902 ft) deep. They feed mainly on small crustaceans such as copepods, as well as shrimp and small fish. They are similar to the yellowtail horse mackerel around New Zealand and Australia, apart from having more gill rakers and larger eyes.
The blue jack mackerel is a species of mackerel-like fish in the family Carangidae. Their maximum reported length is 60 cm, with a common length of 25 cm. They are coastal fish found at depths to 370 m off the Bay of Biscay to south Morocco and the western Mediterranean.
The yellowstripe scad, also known as the yellowstripe trevally, yellow-banded trevally, smooth-tailed trevally, slender-scaled trevally and slender trevally, is a species of small inshore fish in the jack and horse mackerel family Carangidae, and the only member of the genus Selaroides. The yellowstripe trevally is distributed throughout the tropical waters of the Indo-West Pacific region, ranging from the Persian Gulf in the west to Vanuatu and New Caledonia in the east. The species is distinguished by its prominent lateral yellow band, and differs from the scads of the genus Selar in having a smaller eye and different dentition. Although the yellowstripe scad reaches a maximum recorded length of 22 cm, it is normally encountered at sizes less than 15 cm. Phylogenetic studies indicate the yellowstripe scad is closely related to the scads of the genus Selar, although its exact placement in the family Carangidae is less well agreed upon.
Trachurus lathami is a species of fish in the family Carangidae and the genus Trachurus, the jack mackerels. Common names include rough scad and horse mackerel in English, as well as chinchard frappeur (French), chicharro garretón (Spanish), jurel, and carapau, garaçuma, surel, and xixarro. It is native to parts of the western Atlantic Ocean, including seas off the eastern coasts of North and South America and the Gulf of Mexico.
Pseudaxine trachuri is a species of monogenean, parasitic on the gills of a marine fish. It belongs to the family Gastrocotylidae.
Allogastrocotyle bivaginalis is a species of monogenean flatworm, which is parasitic on the gills of a marine fish. It belongs to the family Gastrocotylidae.
The Arabian scad is a species of jack mackerel from the family Carangidae which is found in the Western Indian Ocean.
