Seriola

Seriola is a genus of bony fish, commonly known as amberjacks. Nine extant species are currently recognized, although these were formerly split into many more.[1] Also, several species are currently placed in several other genera of 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 41 kg (90 lb), and are powerful swimmers and hunters, they are also highly prized by sport fisherman.[2]

Most Seriola species are either benthic, demersal or pelagic, and can be found down to 200 m in depth. All 9 species cover most of the globe in terms of distribution, usually in coastal waters. Most are shown to be pelagic spawners, releasing eggs into the open ocean habitat until hatching, and they do this through dioecious, external reproduction. Most Seriola species are found in schools, and have diets consisting of fish, squid and other invertebrates.

Culture[edit]

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 that 80% of global annual production. These cultured species are increasingly used in raw sushi, where they are known as hamachi, buri, kampachi and hiramasa.[3]

Several trials are underway for land-based Seriola culture,[2] but currently most Seriola fish are produced in cages, either in nearshore pens or in high-technology, submersible cages out in the open ocean. They are fed a range of diets, from trash fish to basic compound feeds to complex, formulated, compound feeds.[3]

As is the case with the majority of aquaculture species, the farming of Seriola has associated environmental or other impacts.[2][3]

  • Capture of wild stocks for culture (juveniles/broodstock for hatcheries) can have direct impacts on associated populations and ecosystems.
  • There are environmental concerns over certain feeds used (fishmeal, oils, trash fish, etc.) for cultured carnivorous or piscivorous species.
  • Disease is always of great concern within cultured species in terms of introduction and/or amplification of pathogens and parasites and subsequent infection of wild fish, as well as between farms.
  • Escape of cultured fish is also a concern, which can have effects on wild stocks in terms of competition, predation and genetic alterations, depending on vulnerability and robustness.
  • There is always a risk of pollution and habitat effects via nutrient losses and chemical additives, which can cause problems depending on habitat vulnerability and where the farms are in relation to the coast.

With effective management of regulations and good farming practices, these problems can be avoided.[3] To address these impacts, the WWF is creating the Seriola and Cobia Aquaculture Dialogue (SCAD). The purpose of the SCAD is to create standards that will minimize the key impacts of Seriola/Cobia aquaculture and move producers towards better performance. This will be done by identifying the key environmental and social impacts associated with the farming of three types of Seriola (S. rivoliana, S. quinqueradiata and S. lalandi) and cobia, and principles established for addressing each impact.[2] Then criteria will be developed to provide direction on how to reduce each impact. It is open to all stakeholders, including producers and other members of the supply chain, researchers, NGOs, government officials and investors. The standards (to be 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.[4]

Species[edit]

There are currently nine recognized species in this genus:[5]

Amberjack

Amberjack (or simply jack) is an Atlantic fish of the Carangidae family (genus Seriola). There are three main types of amberjacks: the greater, the lesser and the banded rudderfish.

Types[edit]

Greater amberjacks[edit]

Main article: Greater amberjack

Greater amberjacks, Seriola dumerili, are the largest of the jacks. They usually have dark stripes extending from nose to in front of their dorsal fins. They have no scutes and soft dorsal bases less than twice the length of the anal fin bases. They are usually 18 kg (40 pounds) or less, and are found associated with rocky reefs, debris, and wrecks, typically in 20 to 75 m (10 to 40 fathoms).

Lesser amberjacks[edit]

Lesser amberjacks, Seriola fasciata, have proportionately larger eyes and deeper bodies than greater amberjacks. They are olive green or brownish-black with silver sides, and usually have a dark band extending upward from their eyes. Juveniles have split or wavy bars on their sides. The adults are usually under 5 kg (10 lbs). They are found deeper than other jacks, commonly 50 to 130 m (30 to 70 fathoms).

Amberjacks are voracious predators, which feed on squid, fish, and crustaceans, and are thought to spawn offshore throughout most of the year.

Juveniles can be caught in about 25 feet (7.6 m) of water, near floating objects.

Banded rudderfish[edit]

Banded rudderfish, Seriola zonata, is the second-smallest amberjack. This jack can be distinguished from the pilot fish by the presence of a first dorsal fin. Juveniles are banded vertically like pilotfish, and follow large objects or animals. Large individuals (over 10 inches) have no bands. This fish, though commonly caught, is rarely identified. Large ones, with a raccoon-stripe on the eye and an iridescent gold stripe on the side, are usually called amberjacks when caught, and juveniles are called pilotfish. They are found as far north as Nova Scotia. They are less dependent on sharks, etc., than pilotfish. They can be caught on shrimp, silversides, lures (e.g. spoons) and flies.

Others[edit]

Other species exist in other parts of the world, such as: yellowtail amberjack (including the Asian yellowtail, the California yellowtail, and yellowtail kingfish or southern yellowtail), flat amberjack, and Japanese amberjack (five-ray yellowtail).
