Teraglin, Atractoscion atelodus (Günther 1867)

More Info


Endemic to eastern Australia, from southern Queensland, to off Port Hacking, Sydney, New South Wales. While juveniles inhabit inshore waters including deeper estuaries, adults form schools offshore.


Dorsal fin XI, 31–34; Anal fin A II, 9; Pectoral fin 18–19; Pelvic fin I, 5; Caudal fin 9 + 5; Gill rakers 7 + 1 + 7–9; Vertebrae 25; Lateral line 70–73 pored scales; no canines in adults; caudal fin emarginate.


Teraglin are taken by commercial line fishers in the Ocean Trap and Line Fishery, and significant numbers are taken by recreational fishers. The flesh is reportedly good eating. In New South Wales there is a recreational bag limit of 5 Teraglin,with a minimum legal length of 38 cm total length.

Similar Species

Differs from the similar Mulloway, Argyrosomus japonicus, in having a crescent-shaped tail and yellow inside the mouth and under the gill cover, vs. a rounded tail and no yellow pigment in the mouth or beneath the gill cover in Mulloway.
