Sillaginidae (Smelt-whitings)
Etymology: Sillago: From a locality in Australia .
Environment: milieu / climate zone / depth range / distribution range
البيئة
بحري القاع; محيطية (Ref. 51243); نطاق العمق 1 - 180 m (Ref. 6205), usually ? - 80 m (Ref. 27575). Temperate; 25°S - 44°S, 132°E - 154°E
Western Pacific: southern Queensland to Anxious Bay, South Australia, and the east coast of Tasmania.
Length at first maturity / الحجم / وزن / العمر
Maturity: Lm 14.5, range 14 - 16 cm
Max length : 32.0 cm TL ذكر/ مختلط الجنس; (Ref. 6335); العمر: 7 سنين (Ref. 27578)
الأشواك الظهرية (المجموع) : 12; الأشعة الظهرية الناعمة (المجموع) : 16 - 18; شوكة شرجية: 2; أشعه شرجية لينه: 18 - 20; فقرات: 32 - 34. Coloration is very similar to S. bassensis. No dark spot at the base of the pectoral fin; a series of oblique rusty brown bars on back and upper sides, with a longitudinal row of rusty brown blotches along the midlateral silver stripe.
Live close to the sea bed over sandy substrates. They normally inhabit depths from the surf zone to 80 m (Ref. 27575), although small catches have been taken from deeper water (Ref. 6335). Juveniles congregate in shallow water where they may be taken by line in large quantities. Feed mainly on crustaceans, amphipods, decapods, mysids and copepods. Juveniles consume mostly copepods (Ref. 6223). Oviparous (Ref. 205). Spawn from October to March in southern New South Wales but spawn in winter in southeast Queensland and northern New South Wales (Ref. 6205).
It is likely that this species spawn more than once during the spawning period, and that some eggs are resorbed by females at the end of the spawning season (Ref. 27577).
