Shrimp scad
The shrimp scad (''Alepes djedaba'') (also known as the slender yellowtail kingfish), is a species of widespread tropical marine fish of the jack family, Carangidae. The shrimp scad is widely distributed in the tropical and subtropical western Indian Ocean and areas of the eastern Pacific Ocean, ranging from South Africa in the west to Hawaii in the east, including Japan and Australia to the north and south. The species is commonly found on inshore reefs and sandy substrates. It has the common body profile of a scad, and may be difficult to differentiate from others in the genus ''Alepes''. It is one of the larger scads, growing to 40 cm, but often is encountered at much smaller sizes. The shrimp scad often forms large schools, and is carnivorous, consuming a variety of crustaceans and small fish. It is of moderate importance to fisheries throughout its range.
==Taxonomy and naming==
The shrimp scad is one of five species of fish in the scad genus ''Alepes'', which itself is one of thirty genera in the jack family Carangidae. The Carangidae are Perciform fishes in the suborder Percoidei.
A molecular phylogenetic study has confirmed the genus ''Alepes'' is supported, at least between ''A. djedaba'' and ''A. kleinii'' which are closely related.
The shrimp scad was first scientifically described by Swedish naturalist Peter Forsskål from a specimen collected in the Red Sea in 1775, which was designated to be the holotype. He named the species ''Scomber djedaba'', placing it in the mackerel genus, a common practice with carangids at the time, as the family Carangidae was yet to be erected. A number of taxonomists have since tried to reclassify the species in a more parsimonious genus, with a number of carangid genera proposed including ''Selar'', ''Caranx'' and ''Atule''. To add to the confusion over the species, the species was redescribed twice after the first naming, once by Cuvier who named it ''Caranx kalla'', and once by Fowler who proposed ''Caranx microbrachium'' for the species. ''Caranx kalla'' was subsequently placed in the genus ''Atule'', but is now considered, along with ''Caranx microbrachium'' to be a junior synonym, unacceptable under the ICZN rules and has been discarded. The currently accepted name of ''Alepes djedaba'' was proposed by Gushiken in an extensive review of the carangidae of Japan, identifying a number of morphological features associating it with ''Alepes''. Due to the awkward species name, the species is often misspelt as ''djeddaba'' in the literature.
