Yellowtail scad
The yellowtail scad (''Atule mate'') (also known as the northern yellowtail scad, one-finlet scad, deep trevally and ''omaka''), is an abundant species of small inshore marine fish of the jack family, Carangidae. The species is widespread in the Indo-Pacific region from east Africa in the west to Hawaii in the east, extending north to Japan and south to Australia. The yellowtail scad is the only member of the monotypic genus ''Atule'' and is distinguished from similar species by a well-developed adipose eyelid and finlet-like extensions of the last rays of the dorsal and anal fins. It inhabits coastal areas such as bays and coral reefs, preying on small fishes and crustaceans. Spawning has been well studied in Hawaii, where fish enter bays to spawn, releasing up to 161,000 eggs each between March and October. The yellowtail scad is an important component of fisheries throughout its range, taken by a number of netting and hook-and-line methods. It is a prized food fish in some regions and is cooked or preserved by a variety of methods.
==Taxonomy and naming==
The yellowtail scad is the only member of the monotypic genus ''Atule'', one of 30 genera in the jack and horse mackerel family Carangidae. The Carangidae are perciform fish in the suborder Percoidei.
The yellowtail scad was first scientifically described by the French naturalist Georges Cuvier in 1833 based on a specimen taken from the Seychelles, which was designated to be the holotype.〔 〕 He named the species ''Caranx mate'', thereby placing the species in a genus with a number of larger, deeper bodied jacks. The species was subsequently redescribed and named many times, with most authors placing these "species" in other jack genera including ''Caranx'', ''Decapterus'' and ''Selar''. In 1906, Jordan and Seale produced one such name in the form of ''Decapterus lundini''. Jordan later re-examined this taxon and decided it warranted its own, separate genus and thus created ''Atule'', making ''Decapterus lundini'' the type species of the genus. With the taxonomic history of the species confused with numerous synonyms, it was not until 1953 that Herre concluded that ''D. lundini'' was a junior synonym of Cuvier's ''C. mate'', thus giving the latter priority and creating the currently accepted name of ''Atule mate''.〔
The wide distribution of the species has led to many common names being applied to the species. In English, the most common name is yellowtail scad or some variation of this. Occasionally this combination will be proceeded by a variety of words including "barred" and "northern".〔 Other names applied include one-finlet scad, deep trevally, the broad name of horse mackerel as well as the Hawaiian 'Omaka'.
