42-829: Seriola is a genus of ray-finned fish , with many species commonly known as amberjacks . Nine extant species are currently recognized, although these were formerly split into many more. Also, several species are currently placed in several other genera of the Carangidae that were originally described under Seriola . They are a large, carnivorous finfish popularly known for the firm texture and rich flavour of their flesh, which make them an ideal fish for aquaculture . Because specimens caught can weigh up to 100 kg (220 lb), and are powerful swimmers and hunters, they are also highly prized by sport fisherman. Most Seriola species are either benthic , demersal , or pelagic , and can be found down to 200 m. All 9 species cover most of
84-535: A desirable restaurant dish, pushing the need for aquaculture. Species of Seriola have been grown in aquaculture around the world for decades and will likely soon develop on the west coast of the United States . This fish is prime for aquaculture sexual maturity is reached early in their lives, between 2 and 3 years. Quick maturity is ideal for aquaculture, as it allows rapid population growth since it doesn’t take long for individuals to reproduce. Seriola dorsalis
126-464: A distinct species from the yellowtail amberjack ( S. lalandi ). The California yellowtail is differentiated from yellowtail amberjack as they differ in range. The yellowtail amberjack is found farther south in the Pacific Ocean . The California yellowtail can be recognized by its fusiform body plan, which tapers at both the anterior and posterior ends, a bulbous shaped head slightly swelled above
168-459: A free-swimming larval stage. However other patterns of ontogeny exist, with one of the commonest being sequential hermaphroditism . In most cases this involves protogyny , fish starting life as females and converting to males at some stage, triggered by some internal or external factor. Protandry , where a fish converts from male to female, is much less common than protogyny. Most families use external rather than internal fertilization . Of
210-726: A trait still present in Holostei ( bowfins and gars ). In some fish like the arapaima , the swim bladder has been modified for breathing air again, and in other lineages it have been completely lost. The teleosts have urinary and reproductive tracts that are fully separated, while the Chondrostei have common urogenital ducts, and partially connected ducts are found in Cladistia and Holostei. Ray-finned fishes have many different types of scales ; but all teleosts have leptoid scales . The outer part of these scales fan out with bony ridges, while
252-587: Is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called lepidotrichia , as opposed to the bulkier, fleshy lobed fins of the sister class Sarcopterygii (lobe-finned fish). Resembling folding fans , the actinopterygian fins can easily change shape and wetted area , providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to
294-451: Is a highly popular game fish that is caught with live bait on hook and line for both recreation and sports fishing . The recreational catch is often found to be much higher than the commercial catch, according to reports on the NOAA fisheries website. In 2021, the total commercial catch was 39.291 lbs., while the recreational catch was 209,131 lbs. In 2022, the total commercial catch
336-400: Is deep forked, with lobes of equal size and short length. The shape of the yellowtail’s tail is ideal for its fast and long-distance travel swimming needs, as it is streamlined and propels the fish forward. The California yellowtail, like most other fish, has a lateral line that gives the fish an awareness of its surroundings in the water, allowing it to sense water movement nearby. It runs above
378-540: Is divided into the infraclasses Holostei and Teleostei . During the Mesozoic ( Triassic , Jurassic , Cretaceous ) and Cenozoic the teleosts in particular diversified widely. As a result, 96% of living fish species are teleosts (40% of all fish species belong to the teleost subgroup Acanthomorpha ), while all other groups of actinopterygians represent depauperate lineages. The classification of ray-finned fishes can be summarized as follows: The cladogram below shows
420-590: Is known to have a range of habitats, as they are both nearshore pelagic. The California yellowtail can be found in the shallows, feeding on the edges of rocky points or in kelp forests , and is typically found just below the surface. Differences in habitat have been found based on the life history and size of the fish, smaller fish are more prevalent offshore, and were also found to travel farther offshore than large individuals found nearshore. Nearshore habitats are usually associated with kelp beds, where California yellowtails are also known to spawn and attach their eggs to
462-571: Is open to all stakeholders, including producers and other members of the supply chain, researchers, nongovernmental and governmental organizations, and investors. The standards (finalised late 2011) will be adopted by the Aquaculture Stewardship Council , which will then work with independent, third-party entities to certify farms that are in compliance with the standards. Nine recognized species are placed in this genus: Fishbase includes populations of fish similar to S. lalandi in

#1733202668536504-432: Is relatively rare and is found in about 6% of living teleost species; male care is far more common than female care. Male territoriality "preadapts" a species for evolving male parental care. There are a few examples of fish that self-fertilise. The mangrove rivulus is an amphibious, simultaneous hermaphrodite, producing both eggs and spawn and having internal fertilisation. This mode of reproduction may be related to
546-461: The California yellowtail is a species of ray-finned fish of the family Carangidae . This species is also known by several alternate names, such as yellowtail jack amberjack, forktail, mossback, white salmon and yellowtail tunis or tuna or by its Spanish name jurel. Although previously thought to belong to S. lalandi , recent genetic analysis distinguished California yellowtail ( S. dorsalis ) as
588-500: The Cyprinidae (in goldfish and common carp as recently as 14 million years ago). Ray-finned fish vary in size and shape, in their feeding specializations, and in the number and arrangement of their ray-fins. In nearly all ray-finned fish, the sexes are separate, and in most species the females spawn eggs that are fertilized externally, typically with the male inseminating the eggs after they are laid. Development then proceeds with
630-587: The deep sea to subterranean waters to the highest mountain streams . Extant species can range in size from Paedocypris , at 8 mm (0.3 in); to the massive ocean sunfish , at 2,300 kg (5,070 lb); and to the giant oarfish , at 11 m (36 ft). The largest ever known ray-finned fish, the extinct Leedsichthys from the Jurassic , has been estimated to have grown to 16.5 m (54 ft). Ray-finned fishes occur in many variant forms. The main features of typical ray-finned fish are shown in
672-481: The oviparous teleosts, most (79%) do not provide parental care. Viviparity , ovoviviparity , or some form of parental care for eggs, whether by the male, the female, or both parents is seen in a significant fraction (21%) of the 422 teleost families; no care is likely the ancestral condition. The oldest case of viviparity in ray-finned fish is found in Middle Triassic species of † Saurichthys . Viviparity
714-651: The sister lineage of all other actinopterygians, the Acipenseriformes (sturgeons and paddlefishes) are the sister lineage of Neopterygii, and Holostei (bowfin and gars) are the sister lineage of teleosts. The Elopomorpha ( eels and tarpons ) appear to be the most basal teleosts. The earliest known fossil actinopterygian is Andreolepis hedei , dating back 420 million years ( Late Silurian ), remains of which have been found in Russia , Sweden , and Estonia . Crown group actinopterygians most likely originated near
756-1036: The type species of the genus, the greater amberjack . Though most of the Seriola species are considered "amberjacks", the species Seriola hippos (samson fish) is not. More than 150,000 tonnes of Seriola are produced through aquaculture per year. The majority is produced in Japan and Korea ( Seriola quinqueradiata , Seriola dumerili , and Seriola lalandi ), with smaller contributions from New Zealand / Australia ( Seriola lalandi ) and America ( Seriola rivoliana ). Japanese yellowtail ( Seriola quinqueradiata ) accounts for more than 80% of global annual production. These cultured species are increasingly used in raw sushi , where they are known as hamachi , buri , kampachi , and hiramasa . Several trials are underway for land-based Seriola culture, but currently, most Seriola fish are produced in cages, either in nearshore pens or in high-technology, submersible cages out in
