The razorbelly scad (Alepes kleinii) (also known as the banded scad, golden scad and goggle-eye scad) is a small species of

fisheries
, where it is marketed fresh or dried.

Taxonomy and naming

The razorbelly scad is classified in the scad genus Alepes, which is part of the jack family, Carangidae. The Carangidae are part of the order Carangiformes.[3]

Like a number of other members of Alepes, the razorbelly scad suffers from a complicated

Fishbase, the species also is known as banded scad, goggle-eye scad and golden scad.[2]

Phylogeny

Although the species, including many of its synonyms, has been placed in the genus Alepes for some time, the nature of its teeth has made this placement controversial. Two authors have argued that the species should be reassigned to a new

molecular phylogenetic study of the Carangidae in which A. kleinii and A. djedaba (Shrimp scad) were included. The results confirmed the placement of A. kleinii in Alepes, with the authors arguing the two species were too closely related to warrant placement in a new genus.[8]

Description

vertebrae and a total of 38 to 44 gill rakers.[11]
It is a fairly small fish compared to most carangids, only known to reach 16 cm in length.

Whilst alive, the razorbelly scad is a bluish grey to greenish grey on the upper body, becoming lighter and more silvery ventrally. Dark vertical bands are sometimes present on the body above the lateral line, and a large black spot is present on the upper operculum and surrounding shoulder region. The fins are pale to hyaline with the exception of the caudal fin which is yellow to dusky in colour, with the upper lobe generally brighter and having a narrow dusky edge.[10]

Distribution and habitat

The razorbelly scad is broadly distributed over the tropical

South East Asian coasts, extending throughout Indonesia, Philippines, Taiwan, reaching as far north as Japan and as far south as northern Australia.[9] As Caranx kalla, the species was recorded at least once in the Mediterranean Sea, passing through the Suez Canal from the Red Sea as part of the Lessepsian migration.[12]
The species inhabits inshore
coastal environments, especially reef habitats.[2]

Biology and fishery

fish eggs taken.[13]

Reproduction and

pelagic, spherical and transparent, measuring 0.58 to 0.61 mm in diameter. Newly hatched larvae are 1.13 mm in diameter, and the developmental biology of the larvae has been well studied.[15] The fecundity of the species has been shown to be correlated with total length and body weight.[14]
The growth of razorbelly scad was also studied off the Indian coast near Mangalore. It was found the species grows to 83–84 mm in its first year, 131 mm in the second and 143 mm in the third year of its life.[16] From the data collected, the growth curve predicts a maximum size of 17.1 cm, although it would require a long lifespan.[16] Each sex reaches sexual maturity at a different size, in males it is 128.5 mm and 126.5 mm in females.[14]

The species is commonly taken as part of a number of

subsistence fishing gear.[9] Razorbelly scad is marketed
fresh and dried salted.
