The mackerel, tuna, and bonito family, Scombridae, includes many of the most important and familiar food fishes. The family consists of 51 species in 15 genera and two subfamilies. All species are in the subfamily Scombrinae, except the butterfly kingfish, which is the sole member of subfamily Gasterochismatinae. [1]
Scombrids have two dorsal fins and a series of finlets behind the rear dorsal fin and anal fin. The caudal fin is strongly divided and rigid, with a slender, ridged base. The first (spiny) dorsal fin and the pelvic fins are normally retracted into body grooves. Species lengths vary from the 20 cm (7.9 in) of the island mackerel to the 4.58 m (15.0 ft) recorded for the immense Atlantic bluefin tuna.
Scombrids are generally predators of the open ocean, and are found worldwide in tropical and temperate waters. They are capable of considerable speed, due to a highly streamlined body and retractable fins. Some members of the family, in particular the tunas, are notable for being partially endothermic (warm-blooded), a feature that also helps them to maintain high speed and activity. Other adaptations include a large amount of red muscle, allowing them to maintain activity over long periods. Scombrids like the yellowfin tuna can reach speeds of 22 km/h (14 mph). [2]
Jordan, Evermann, and Clark (1930) divide these fishes into the four families: Cybiidae, Katsuwonidae, Scombridae, and Thunnidae, [3] but taxonomists later classified them all into a single family, the Scombridae. [4] [5]
The World Wildlife Fund and the Zoological Society of London jointly issued their "Living Blue Planet Report" on 16 September 2015 which states that a dramatic fall of 74% occurred in worldwide stocks of scombridae fish between 1970 and 2010, and the global overall "population sizes of mammals, birds, reptiles, amphibians and fish fell by half on average in just 40 years". [6]
The 51 extant species are in 15 genera and two subfamilies – with the subfamily Scombrinae further grouped into four tribes, as:
The following fossil genera are known: [7]
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.
Bonitos are a tribe of medium-sized, ray-finned predatory fish in the family Scombridae – a family it shares with the mackerel, tuna, and Spanish mackerel tribes, and also the butterfly kingfish. Also called the tribe Sardini, it consists of eight species across four genera; three of those four genera are monotypic, having a single species each. Bonitos closely resemble the skipjack tuna, which is often called a bonito, especially in Japanese contexts.
Scombroid food poisoning, also known as simply scombroid, is a foodborne illness that typically results from eating spoiled fish. Symptoms may include flushed skin, sweating, headache, itchiness, blurred vision, abdominal cramps and diarrhea. Onset of symptoms is typically 10 to 60 minutes after eating and can last for up to two days. Rarely, breathing problems, difficulty swallowing, redness of the mouth, or an irregular heartbeat may occur.
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 double-lined mackerel, is a species of Spanish mackerel in the family Scombridae. This species is sometimes also called the scad mackerel.
The dogtooth tuna, also known as white tuna, is a species of pelagic marine fish which belongs to the family Scombridae. Despite the name “tuna”, it is not actually a tuna. Instead, it is a bonito.
The Australian bonito, horse mackerel or little bonito, Sarda australis is a ray-finned fish of the family Scombridae and is found in eastern Australia and New Zealand. They swim at depths reaching depths of approximately 30 m (98 ft), in open water. Its length is commonly at around 40–45 centimetres (16–18 in) fork length and 1.8–2.3 kilograms (4.0–5.1 lb) weight. Its maximum length and weight are about 100 centimetres (39 in) and 9.4 kilograms (21 lb), respectively.
The butterfly kingfish is an ocean-dwelling ray-finned bony fish in the mackerel family, Scombridae – a family which it shares with the tunas, mackerels, Spanish mackerels, and bonitos. It, however, represents a lineage distinct from all other scombrids and has therefore been placed in its own genus Gasterochisma and subfamily Gasterochismatinae.
The Gempylidae are a family of scombriform ray-finned fishes commonly known as snake mackerels or escolars. The family includes about 25 species.
The Atlantic bonito is a large mackerel-like fish of the family Scombridae. It is common in shallow waters of the Atlantic Ocean, the Mediterranean Sea, and the Black Sea, where it is an important commercial and game fish.
Scomberomorini is a tribe of ray-finned saltwater bony fishes that is commonly known as the Spanish mackerels, seerfishes or seer fish. This tribe is a subset of the mackerel family (Scombridae) – a family that it shares with three sister tribes, the tunas, mackerels, and bonitos, and the butterfly kingfish. Scomberomorini comprises 21 species across three genera. They are pelagic fish, fast swimmers and predatory in nature, that fight vigorously when caught. They are mainly caught using hooks and lines.
The little tunny, also known as the bacora, little tuna, bonita, or erroneously as the blue bonito, is a species of tuna in the family Scombridae. It can be found in the Atlantic Ocean and the Mediterranean and Black seas; in the western Atlantic, it ranges from Brazil to the New England states. The little tunny is a pelagic fish that can be found regularly in both offshore and inshore waters, and it is classified as a highly migratory species. The little tunny is best identified by the "worm-like" markings on its back and the dark spots appearing between its pectoral and ventral fins.
Scombroidei is a suborder of the order Scombriformes. The suborder includes the tunas, mackerel and snake-mackerels. Regular scombrids are observed to have large heads, eyes, and mouths. In most cases, the second dorsal fin will develop before the development of the first.
Scomber is a genus of ray-finned fish in the family Scombridae living in the open ocean found in Atlantic, Indian and Pacific Ocean. The genus Scomber and the genus Rastrelliger comprise the tribe Scombrini, known as the "true mackerels". These fishes have an elongated body, highly streamlined, muscular and agile. The eyes are large, the head is elongated, with a big mouth provided with teeth. They have two triangular dorsal fins, with some stabilizing fins along the caudal peduncle. The basic color is blue-green with a silvery white belly and a darker back, usually black mottled.
Euzaphlegidae is a family of extinct escolar-like ray-finned fish closely related to the snake mackerels. Fossils of euzaphlegids are found from Paleocene to Late Miocene-aged marine strata of Europe, the Caucasus Mountains, India, Iran, Turkmenistan, Italy, and Southern California.
Aramichthys is an extinct genus of prehistoric marine scombrid fish that lived during the middle division of the Eocene epoch. It contains a single species, A. dammeseki from Syria. Its remains were recovered from a chalk-marl quarry in the vicinity of Dummar.
The leaping bonito is a species of saltwater finfish from the Scombridae (Mackerel) family. Scombridae includes such tribes as the mackerels, tunas, and bonitos – of the latter of which, the Sardini tribe, this fish is a member. It is the only member of the genus Cybiosarda, which is therefore called a monotypic taxon. Since the bonitos and tunas are close relatives, this fish has variously been referred to by such other common names as Australian tuna, striped bonito, and Watson's bonito.
The Scombrinae are a subfamily of ray-finned bony fishes in the family Scombridae. Of the 51 species in the Scombridae, 50 are in Scombrinae – with the sole exception being the butterfly kingfish, which is placed in the monospecific subfamily Gasterochismatinae.
Scombrini, commonly called the true mackerels, is a tribe of ray-finned bony fishes in the mackerel family, Scombridae – a family it shares with the Spanish mackerel, tuna and bonito tribes, plus the butterfly kingfish.
Scombriformes, also known as Pelagia and Pelagiaria, is an order of ray-finned fish within the clade Percomorpha. It contains 287 extant species in 16 families, most of which were previously classified under the suborders Scombroidei and Stromateoidei of the order Perciformes.
