Max length : 60.0 cm TL hane/ej könsbestämd; (Ref. 9710); common length : 40.0 cm TL hane/ej könsbestämd; (Ref. 5450); publicerad maxvikt: 8.0 kg (Ref. 37816)

Diagnosis: Characterized by having membranous, digitate posterior margin on scales; snout shorter than eye diameter; slender maxilla and weakly curved ventrally at posterior tip, partially or completely concealed; poorly developed adipose eyelid as rim around eye; preorbital weakly concave on anteroventral edge (Ref. 90102).
Body shape (shape guide): fusiform / normal; Cross section: oval.
Found in coastal waters but enters estuaries and rivers where they feed on microalgae, filamentous algae, forams, diatoms, and detritus associated with sand and mud (Ref. 9812). Form schools. Oviparous, eggs are pelagic and non-adhesive (Ref. 205). Also caught using stakenets, barrier nets, and pouch nets during spawning; also taken as bycatch (Ref. 9812). Marketed fresh and perhaps salted, boiled (Thailand), canned or frozen (Australia); roe salted (Ref. 9812).
