Summary:
A green to bluish-green trevally becoming silver below, with or without small golden to dark orange spots (usually less than 30) scattered on the sides, olive green dorsal, anal, caudal and pelvic fins, and often white tips on the soft dorsal and anal fins. Juveniles to 200 mm are silver to silvery-green with a few scattered golden spots on the side, and a dark line running obliquely through the eye that fades with age.

This species is often misidentified as Carangoides fulvoguttatus.

More Info


Distribution

Widespread in northern Australia, from Coral Bay, Western Australia, to Moreton Bay, Queensland. Elsewhere the species occurs in the tropical, Indo-west Pacific from South Africa to New Caledonia, and north to the Ryukyu Islands, Japan. Adults usually inhabit deeper offshore reefs in depths to 100 m.

Features

Dorsal fin VIII + I, 28-33; Anal fin ll + I, 24-27; Gill rakers 8-9 + 19-22 = 28-31.
Naked area on breast extending up to, but not above, pectoral fin base; head profile relatively steep in small juveniles (less than 150 mm LCF) becoming less steep with age, large adults elongate with very shallow head profile (angle of head with the horizontal axis of the body 33-42°). Curved portion of lateral line gently to moderately arched.

Colour

Juveniles to 200 mm are silver to silvery-green with a few scattered golden spots on the side, and a dark line running obliquely through the eye, fading with age. Larger individuals are green to bluish-green above, silver below, with or without gold to golden brown spots (usually less than 30) scattered on the sides, olive green dorsal, anal, caudal and pelvic fins, and often white tips on the soft dorsal and anal fins. 

Feeding

Feeds on mostly on crustaceans, and also consumes smaller fishes.

Fisheries

Taken in artisanal fisheries and by recreational fishers throughout its range.
