Amberjacks are Atlantic and Pacific fish in the genus Seriola of the family Carangidae. They are widely consumed across the world in various cultures, most notably for Pacific amberjacks in Japanese cuisine; they are most often found in the warmer parts of the oceans. There are many variations of amberjack, including greater amberjack (Atlantic), lesser amberjack (Atlantic), Almaco jack (Pacific), yellowtail (Pacific), and the banded rudderfish (Atlantic). Though most of the Seriola species are considered "amberjacks", the species Seriola hippos is not.
Fish migration is mass relocation by fish from one area or body of water to another. Many types of fish migrate on a regular basis, on time scales ranging from daily to annually or longer, and over distances ranging from a few metres to thousands of kilometres. Such migrations are usually done for better feeding or to reproduce, but in other cases the reasons are unclear.
The albacore, known also as the longfin tuna, is a species of tuna of the order Scombriformes. It is found in temperate and tropical waters across the globe in the epipelagic and mesopelagic zones. There are six distinct stocks known globally in the Atlantic, Pacific, and Indian oceans, as well as the Mediterranean Sea. The albacore has an elongate, fusiform body with a conical snout, large eyes, and remarkably long pectoral fins. Its body is a deep blue dorsally and shades of silvery white ventrally. Individuals can reach up to 1.4 m in length.
The yellowfin tuna is a species of tuna found in pelagic waters of tropical and subtropical oceans worldwide.
Lancetfishes are large oceanic predatory fishes in the genus Alepisaurus in the monogeneric family Alepisauridae.
Pelagic fish live in the pelagic zone of ocean or lake waters—being neither close to the bottom nor near the shore—in contrast with demersal fish that live on or near the bottom, and reef fish that are associated with coral reefs.
A fish aggregatingdevice (FAD) is a man-made object used to attract pelagic fish such as marlin, tuna and mahi-mahi. They usually consist of buoys or floats tethered to the ocean floor. FADs attract fish for reasons that vary by species.
The bigeye tuna is a species of true tuna of the genus Thunnus, belonging to the wider mackerel family Scombridae. In Hawaiian, it is one of two species known as ʻahi, the other being the yellowfin tuna. Bigeye tuna are found in the open waters of all tropical and temperate oceans, but not in the Mediterranean Sea.
The Atlantic pomfret, also known as Ray's bream, is a species of marine ray-finned fish, a pomfret of the family Bramidae. It is found in the Atlantic, Indian, and South Pacific Oceans, at depths down to 1,000 m (3,300 ft).
Thunnus is a genus of ocean-dwelling, ray-finned bony fish from the mackerel family, Scombridae. More specifically, Thunnus is one of five genera which make up the tribe Thunnini – a tribe that is collectively known as the tunas. Also called the true tunas or real tunas, Thunnus consists of eight species of tuna, divided into two subgenera.
The rainbow runner, also known as the rainbow yellowtail, Spanish jack and Hawaiian salmon, is a common species of pelagic marine fish of the jack family, Carangidae. The species is widespread throughout the tropical and subtropical waters of the world, inhabiting both coastal and offshore areas. The species is the only member of the genus Elagatis, which was created 15 years after its initial description, and is closely related to the amberjacks. The rainbow runner is easily distinguished by its body shape, and the brilliant colouration which gives the fish its name. It is a fast-swimming predator, taking small fish, cephalopods, and a wide variety of planktonic crustaceans. The species reaches sexual maturity around 60 cm (24 in), and spawning takes place at different times, with some populations spawning year round, while others only spawn at certain times of the year. The species is a well known game fish, taken by a variety of fishing methods, and is a well-regarded table fish. Large numbers of the species are taken as bycatch in tuna- and shark-fishing operations and marketed.
Cross Seamount is a seamount far southwest of the Hawaii archipelago, about equidistant from the cities of Honolulu and Kona. It is one of the numerous seamounts surrounding Hawaii, although unrelated to the Hawaiian hotspot. It is notable for being one of the best studied of the numerous seamounts surrounding Hawaii, as it has been included in numerous biological surveys, most recently in 2007. It is also a site of offshore fishing, for its abundant tuna. The fishery management problems at Cross Seamount are typical of management problems in many fisheries, and its small size makes it a scientifically useful model for the analysis of fishery management.
Brama is a genus of marine ray-finned fishes from the family Bramidae, the pomfrets. Currently, there are 8 species within the genus.
Taractes is a genus of marine ray-finned fishes from the family Bramidae, the pomfrets. Taractes can be distinguished from other bramid genera but having a flat, or slightly curved profile, between the eyes and by having scales on both the dorsal and anal fins.
The Republic of the Marshall Islands has a commercial fishery that targets bigeye and yellowfin tuna using pelagic longline fishing gear. There were 55 longline vessels licensed to fish in the Republic of the Marshall Islands Exclusive Economic Zone (EEZ) in 2011, of which 4 were Marshall Islands-flagged and 51 were foreign-licensed vessels, including 22 Chinese-flagged, 16 Japanese-flagged, 11 Federated States of Micronesia-flagged, and 2 Taiwan-flagged. The Japanese-flagged longliners land their catch in Japan; the other 39 vessels were domestically-based. In 2011, the Marshall Islands longline fleet had reported landings of principal market species of 259 mt of bigeye tuna, 99 mt of yellowfin tuna, 37 mt of blue marlin, 7 mt of black marlin, 4 mt of albacore tuna, and 3 mt of broadbill swordfish. Fresh chilled bigeye and yellowfin tuna is exported primarily to markets in the U.S., China and Canada, and frozen tuna and incidental market species are exported to China and marketed locally.
Taractichthys steindachneri, the sickle pomfret, is a species of marine ray-finned fish, a pomfret of the family Bramidae. It is found in the Indian and Pacific Oceans.
Brama australis, the Southern Ray's bream or Pacific pomfret, is a species of marine ray-finned fish from the family Bramidae, the pomfrets. It is found in the southern Oceans.
Brama japonica, the Pacific pomfret, is a species of marine ray-finned fish, a pomfret of the family Bramidae. B. japonica is closely related, and quite similar, to Brama brama, but can be distinguished by possessing a greater number of anal fin rays and a higher number of gill rakers.
Taractes rubescens, the pomfret, keeltail pomfret, knifetail pomfret or black pomfret, is a species of marine ray-finned fish, a pomfret of the family Bramidae. T. rubescens is closely related, and quite similar, to Taractes asper, but adults can most easily be distinguished by the bony keel present on the caudal peduncle. In fact, this bony keel is unique to Taractes rubescens and will distinguish it from all other bramids.
Brama caribbea, the Caribbean pomfret, is a species of marine ray-finned fish, a pomfret of the family Bramidae. It is found in the Western Atlantic Ocean.
