Mulloway, Argyrosomus japonicus (Temminck & Schlegel 1844)

More Info


Distribution

Yeppoon, Queensland, around southern Australia, to Exmouth Gulf, Western Australia, including Tasmania. Elsewhere the species occurs in South Africa and the north-west Pacific.
Small juveniles inhabit estuaries and inshore coastal waters. Adults and subadults are found along surf beaches, around rocky headlands and in deeper areas offshore. Individuals also form schools in the lower parts of estuaries and around river mouths during flood periods. The species undertakes seasonal movements along the coast as well as in and out of estuaries. 

Features

Dorsal fin X + I,26-29; Anal fin II,7; Caudal fin 17; Pectoral fin 18-19; Pelvic fin V I,5; Lateral-line scales 46-52. 
Body moderately depth (26-30% SL), slightly elongate, compressed; caudal peduncle of moderate depth. Head moderately small (28-34% SL); eyes moderately small (14-22% HL); mouth of moderate size (upper jaw length 38-45% HL); slightly oblique, maxillae extending nearly to below posterior edge of eyes; teeth pointed, in two series in each jaw; upper jaw with narrow inner band of small teeth, outer composed of irregularly spaced large canines; lower jaw with a row of small teeth outside, though in some places between row of large canines; each operculum with two weak spines.
Scales small, finely ctenoid, covering all of body and head except tip of snout, only single row at base of dorsal and anal fins; lateral line nearly straight, extending to tip of tail. 
Dorsal fin deeply notched dividing fin into short anterior spinous portion and elongate slightly lower posterior portion;  anal fin with short base; caudal fin pointed in young, rear edge becoming S shaped or slightly concave in adults. Pelvic fins arising below and slightly behind pectoral fins.  

Size

Reaches a length of over 2 m and a weight of nearly 60 kg.

Colour

Greyish green to steel blue above, silvery grey below, with darker oblique bands following scale rows in small individuals; inside of mouth and opercula bright orange; fins slightly yellowish; prominent black spot at base of each pectoral fin. 

Feeding

Carnivores, preying on a variety of fishes, crustaceans and squid. Juveniles feed mostly on crustaceans.

Biology

Mulloway spawn just outside of the surf zone, and the eggs and larvae are pelagic.

Fisheries

The mulloway is a popular game and commercial fish with excellent quality flesh. Large individuals provide exciting sport to the angler with their powerful long runs. Those sold in markets are usually taken by net in estuarine areas. 

Remarks

The common name Mulloway is an aboriginal word meaning ‘the greatest one’. Other common names such as jew, jewfish, silver jew, school jew, arose from the term 'jewel fish', referring to the Mulloway's very large otoliths or earbones that were collected for use as jewellery.

Etymology

The specific name refers to the type locality: near Nagasaki, Japan.
