Kajikia Audax
The striped marlin (''Kajikia audax'') is a species of marlin found in tropical to temperate Indo-Pacific oceans not far from the surface. It is a desirable commercial and game fish. The striped marlin is a predator that hunts during the day in the top 100 m or so of the water column, often near the surface. One of their chief prey is sardines. Description The Striped Marlin consists of 42-48 rays on its tall first dorsal fin that is almost the same or longer than its body depth while the second dorsal fin is much smaller. They have torpedo-like and compressed bodies. They have around 10-20 clear, visible bluish stripes on the sides of their bodies even after death. The color of their bodies is dark blue or black above and silvery-white on the bottom. Striped Marlin has an average length of and a maximum length of and can weight up to . Life Cycle Striped Marlin reached sexual maturity at a age of 1-2 years or for males and 1.5-2.5 years or for females. They can live up ...

The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ...

Mahi-Mahi
The mahi-mahi () or common dolphinfish (''Coryphaena hippurus'') is a surface-dwelling ray-finned fish found in off-shore temperate, tropical, and subtropical waters worldwide. Also widely called dorado (not to be confused with ''Salminus brasiliensis'', a fresh water fish) and dolphin, it is one of two members of the family Coryphaenidae, the other being the pompano dolphinfish. These fish are most commonly found in the waters around the Gulf of Mexico, Costa Rica, Hawaii and the Indian Ocean. Nomenclature The name mahi-mahi comes from the Hawaiian language and means "very strong", through the process of reduplication. However in Māori, a sister language of Hawaiian, "mahimahi" almost exclusively refers to the verb meaning to have sex. By chance in Persian, mahi (ماهی) means fish, but the word mahi in Hawaiian has nothing to do with the Persian language. Though the species is also referred to as the common dolphinfish, the use of "dolphin" can be misleading as they are ...

Fisheries Capture Of Tetrapturus Audax
Fishery can mean either the enterprise of raising or harvesting fish and other aquatic life; or more commonly, the site where such enterprise takes place ( a.k.a. fishing ground). Commercial fisheries include wild fisheries and fish farms, both in freshwater waterbodies (about 10% of all catch) and the oceans (about 90%). About 500 million people worldwide are economically dependent on fisheries. 171 million tonnes of fish were produced in 2016, but overfishing is an increasing problem — causing declines in some populations. Because of their economic and social importance, fisheries are governed by complex fisheries management practices and legal regimes that vary widely across countries. Historically, fisheries were treated with a " first-come, first-served " approach, but recent threats by human overfishing and environmental issues have required increased regulation of fisheries to prevent conflict and increase profitable economic activity on the fishery. Modern jurisdictio ...

Jumbo Squid
The Humboldt squid (''Dosidicus gigas''), also known as jumbo squid or jumbo flying squid (EN), and Pota in Peru or Jibia in Chile (ES) is a large, predatory squid living in the eastern Pacific Ocean. It is the only known species of the genus ''Dosidicus'' of the subfamily Ommastrephinae, family Ommastrephidae. Humboldt squid typically reach a mantle length of , making the species the largest member of its family. They are the most important squid worldwide for commercial fisheries, with the catch predominantly landed in Chile, Peru and Mexico, however, a 2015 warming waters fishery collapse in the Gulf of California remains unrecovered. Like other members of the subfamily Ommastrephinae, they possess chromatophores which enable them to quickly change body coloration, known as 'metachrosis’ which is the rapid flash of their skin from red to white. They have a relatively short lifespan of just 1–2 years. They have a reputation for aggression toward humans, although this beha ...

Squid
True squid are molluscs with an elongated soft body, large eyes, eight arms, and two tentacles in the superorder Decapodiformes, though many other molluscs within the broader Neocoleoidea are also called squid despite not strictly fitting these criteria. Like all other cephalopods, squid have a distinct head, bilateral symmetry, and a mantle. They are mainly soft-bodied, like octopuses, but have a small internal skeleton in the form of a rod-like gladius (cephalopod), gladius or pen, made of chitin. Squid diverged from other cephalopods during the Jurassic and occupy a similar role to teleost fish as open water predators of similar size and behaviour. They play an important role in the open water food web. The two long tentacles are used to grab prey and the eight arms to hold and control it. The beak then cuts the food into suitable size chunks for swallowing. Squid are rapid swimmers, moving by Aquatic locomotion#Jet propulsion, jet propulsion, and largely locate their ...

Sardinops Caeruleus
''Sardinops'' is a monotypic genus of sardines of the family Clupeidae. The only member of the genus is ''Sardinops sagax''. It is found in the Indo-Pacific and East Pacific oceans. Its length is up to . It has numerous common or vernacular names, some of which more appropriately refer to subspecies, including blue pilchard, Australian pilchard (''S. s. neopilchardus''), blue-bait, Californian pilchard (''S. s. caeruleus''), Peruvian Pacific sardine (''S. s. sagax''), South American pilchard, Chilean sardine (''S. s. sagax''), Japanese pilchard (''S. s. melanostictus''), Pacific sardine, and Southern African pilchard (''S. s. ocellatus''). South Australian sardine fishery The South Australian sardine fishery targets ''Sardinops sagax'' and is the highest yielding single species fishery in Australia by volume. The fishery employs the technique of purse seining. Schools of sardines are encircled by a net up to 1 kilometre in length which is then drawn closed at the bottom. The ca ...

Etrumeus Sadina
''Etrumeus sadina'', the red-eye round herring, is a species of fish belonging to the family Dussumieriidae, a family notable for their rounded bellies. Description The red-eye round herring has a very slim rounded body. Its anal and pelvic fins are small, and its scales are large and thin. Because of this, they often become dislodged when being caught. Its side and underside are silvery in color, and its back is a murky green. Distribution and habitat Round herrings are found in the northwestern Atlantic Ocean, from the Bay of Fundy to Florida and the Gulf of Mexico The Gulf of Mexico ( es, Golfo de México) is an oceanic basin, ocean basin and a marginal sea of the Atlantic Ocean, largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of .... It can be found inshore during the summer in the northern sections of its occurring range, but in the southern half of its range, it is found farther from the sh ...

Chub Mackerel
The chub mackerel, Pacific mackerel, or Pacific chub mackerel (''Scomber japonicus'') is a species of fish in the tuna and mackerel family, Scombridae. This species of mackerel closely resembles the Atlantic chub mackerel. Characteristics The chub mackerel has a well-developed swim bladder attached with the esophagus, which the "true mackerels" in the genus ''Scomber'' lack, and a characteristic color difference is seen between the chub and the Atlantic chub, the latter being silvery-sided below the midline, whereas the lower part of the sides of the chub (otherwise colored somewhat like the Atlantic) are mottled with small dusky blotches, and the chub has a larger eye than the Atlantic. Less obvious differences are that the dorsal fins are closer together in the chub and only 9 or 10 spines are in its first dorsal fin instead of 11 or more, which is the usual count in the Atlantic mackerel. In most species, the mackerel is known to travel in large schools. It is a smaller fish tha ...

Cephalopod
A cephalopod is any member of the molluscan class Cephalopoda (Greek plural , ; "head-feet") such as a squid, octopus, cuttlefish, or nautilus. These exclusively marine animals are characterized by bilateral body symmetry, a prominent head, and a set of arms or tentacles (muscular hydrostats) modified from the primitive molluscan foot. Fishers sometimes call cephalopods "inkfish", referring to their common ability to squirt ink. The study of cephalopods is a branch of malacology known as teuthology. Cephalopods became dominant during the Ordovician period, represented by primitive nautiloids. The class now contains two, only distantly related, extant subclasses: Coleoidea, which includes octopuses, squid, and cuttlefish; and Nautiloidea, represented by ''Nautilus'' and ''Allonautilus''. In the Coleoidea, the molluscan shell has been internalized or is absent, whereas in the Nautiloidea, the external shell remains. About 800 living species of cephalopods have been ident ...

Tuna
A tuna is a saltwater fish that belongs to the tribe Thunnini, a subgrouping of the Scombridae (mackerel) family. The Thunnini comprise 15 species across five genera, the sizes of which vary greatly, ranging from the bullet tuna (max length: , weight: ) up to the Atlantic bluefin tuna (max length: , weight: ), which averages and is believed to live up to 50 years. Tuna, opah and mackerel sharks are the only species of fish that can maintain a body temperature higher than that of the surrounding water. An active and agile predator, the tuna has a sleek, streamlined body, and is among the fastest-swimming pelagic fish – the yellowfin tuna, for example, is capable of speeds of up to . Greatly inflated speeds can be found in early scientific reports and are still widely reported in the popular literature. Found in warm seas, the tuna is commercially fished extensively as a food fish, and is popular as a bluewater game fish. As a result of overfishing, some tuna species, s ...
