Ambiente: milieu / zona climatica / distribuzione batimetrica / gamma di distribuzione
Ecologia
marino; salmastro demersale; non migratori; distribuzione batimetrica 0 - 50 m (Ref. 6205). Subtropical; 12°S - 39°S, 143°E - 157°E (Ref. 6205)
Western Pacific: endemic to Australia. Records of this species from western Australia or northern Australia refer to Sillago burrus. Also very similar to Sillago aeolus from southeast Asia (Sunda Shelf). Occurrence in Tanzania (Ref. 2871) is probably a misidentification.
Lunghezza alla prima maturità / Dimensione / Peso / Età
Maturità: Lm 19.0  range ? - ? cm
Max length : 30.0 cm TL maschio/sesso non determinato; (Ref. 6205); common length : 25.0 cm SL maschio/sesso non determinato; (Ref. 9679)
Spine dorsali (totale) : 12 - 13; Raggi dorsali molli (totale) : 19 - 21; Spine anali: 2; Raggi anali molli: 19 - 20; Vertebre: 34 - 36. Anterolateral extensions of swim bladder recurved posteriorly to reach level of vent. Base of pectoral fin with black spot, back and sides with dark blotches. The upper and lower blotches are frequently joined, at least posteriorly, the upper blotches are generally larger; the opercle is dull or with an inner dark blotch showing through. Coloration is similar to S. burrus and S. aeolus.
Body shape (shape guide): elongated; Cross section: circular.
Occur on silty and muddy substrates in the deeper water of bays, but also frequenting the mouths of rivers, estuaries, and mangrove creeks. Juveniles abound in estuaries and shallow water during summer, moving deeper as they mature. Diet of juveniles consist largely of small crustaceans and that of the adult fish consist mainly of polychaete worms and bivalve mollusks. Oviparous (Ref. 205). Spawn throughout the year with peaks in Dec.-Feb. (Ref. 6390). Marketed fresh (Ref. 9987) and chilled (Ref. 6390).
They spawn several times each year (Ref. 26745).
