Argyrosomus japonicus is a silvery to bronze-green colored fish, a member of the family Sciaenidae, which may grow up to 2 m (6 ft 7 in) in length.

[3] Argyrosomus japonicus has an Indo-Pacific distribution occurring in coastal waters surrounding Australia, Africa, India, Pakistan, China and Japan.

[citation needed] Later in 2018, NSW Minister for Primary Industries, Niall Blair commented:[7] Despite efforts by fishers, a recent scientific review showed Mulloway are still overfished.

In order for stocks to recover, the review recommended that more action needed to be taken.Recreational bag limits were further reduced to just one fish over 70 cm.

[8] Mulloway or jewfish can be found from the brackish water up the top of estuaries down to the mouths, bays, rocks and beaches all the way out to offshore reefs.

They can be found under deep water marinas, boat moorings, bridges and jetties even shelving rocks and caves.

[11] Kob that are less than 110cm total length are commonly targeted by estuarine and surf-zone anglers, while adults are caught mainly while recreational deep sea fishing.
