Issue
Genetic data indicate that it is a complex of species having apparently similar distribution ranges in the Indo-Pacific (Ref. 114224).
Environment: milieu / climate zone / kisaran kedalaman / distribution range
Ekologi
laut; air tawar; payau berasosiasi dengan karang; katadromus (ruaya dari air tawar ke laut) (Ref. 46888); kisaran kedalaman 0 - 3 m (Ref. 86942). Tropical; 35°N - 32°S, 28°E - 135°W
Indo-Pacific: Red Sea, south to Transkei, South Africa (Ref. 4393) and east to the Hawaiian and Marquesan islands, north to southern Japan, south to New Caledonia and Norfolk Island (Ref. 8879) and Tuamotu Islands (Ref. 90102).
Size / Weight / umur
Kematangan: Lm ? range ? - ? cm
Max length : 60.0 cm TL jantan/; (Ref. 9710); common length : 40.0 cm TL jantan/; (Ref. 5450); Berat maksimum terpublikasi: 8.0 kg (Ref. 37816)
Duri punggung (Keseluruhan (total)) : 5; duri punggung lunak (Keseluruhan (total)) : 8 - 9; Duri dubur: 3; Sirip dubur lunak: 9. 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).
