Character: Dorsal fin X, I, 26-30; anal fin II, 7; pectoral fin I, 15-16; pelvic fin I, 5; lateral-line scales 47-50; gill-rakers 6-7 + 12-14; A large, elongate and compressed species with an acute snout and a large terminal mouth, the jaws meeting evenly in front or the lower slightly longer. No canine teeth. 5 marginal pores, 3 rostral pores. Without barbel but with three pairs of mental pores(Fig. 1): the median pair rounded, the second oval or elongate, and third pair narrow slits, each pair progressively further apart. Gill rakers slender, shorter than gill filaments at angle of arch (Fig. 2). Lateral line with regularly sparkling scales along lateral line (Fig. 3). Caudal fin nearly truncate, biconcave. Sagitta morphology referred to as the Argyrosomus form(Fig. 4), moderately elongate and roughly triangular; ventral margin evenly rounded in smaller otoliths, becoming straighter with growth, with a bulge in the posterior third; margin of ventral bulge often denticulate; dorsal margin slightly convex; posterior margin generally straight and posterodorsal angle 90° or less; posteroventral angle becomes more acute with size; inner (medial) surface slightly convex with a tadpole-shaped impression, which head heart shaped, tail bended ventrally with a pointed tip(Fig. 5). Swim-bladder morphology referred to as the Argynosomus form, swim-bladder typically carrot-shaped with 21-31 pairs of arborescent appendages, branched in a fan manner; those along anterior half of bladder divided basally into dorsoposterior and lateroanterior limbs, but along posterior half of bladder, the lateroanterior limbs become ventroanteriorly orientated, and the branches arising from them are orientated posteriorly, lying against the bladder. As a result, the arborescent appendages of the posterior half of the swim-bladder are not clearly visible in ventral view. Disproportionate enlargement of 1-6 appendages occurs with increased size; None entering head, the posterior few very short, at right angles to the main bladder. 
Habitat: Adult fish found mainly near shore, occasionally going inshore. Juveniles exclusively found inshore. Juveniles recruit to estuaries at about 30 cm TL. 
Distribution: Southern China, northward to southern Jappan; South,Sau-luchu,Pon_Fu,West 
Utility: An important food fish.
