How to catch Brassy trevally
Caranx papuensis Alleyne & MacLeay, 1877
About Brassy trevally fishing
The brassy trevally is a robust marine fish belonging to the jack family Carangidae, recognised by its oblong, compressed body, gently convex dorsal profile, and distinctive brassy to yellowish-green upper sides that fade to silvery white below. Adults display numerous small black spots scattered across the upper body and a prominent pale silvery-white spot near the upper edge of the opercle, alongside yellow to dusky fins featuring a characteristic narrow white border on the lower caudal lobe. Growing to a maximum length of 88 centimetres and a weight of 6.4 kilograms, this species inhabits both brackish and saltwater environments across a depth range of 1 to 50 metres, frequenting lagoon and seaward reefs as adults while utilising estuaries and mangrove creeks during juvenile stages. As active visual predators, they hunt primarily on small fish and crustaceans, moving either solitarily or in small groups through warm tropical and subtropical waters.

When to fish for Brassy trevally
How to catch Brassy trevally
Tips for catching Brassy trevally
Anglers target this aggressive predator by working coastal structures, drop-offs, and reef edges where strong currents bring small forage fish and crustaceans. Because these fish are active hunters that respond well to rapid movement, casting surface lures, stickbaits, or metal jigs on medium spinning tackle yields frequent strikes during early morning and late afternoon hours. When lure presentation is slow, presenting fresh cut fish or squid on a running sinker rig near the seabed around rocky outcrops or channel entrances increases success. Use abrasion-resistant leaders to prevent cut-offs against sharp coral and rock structures during their powerful, fast runs.
