Above this size the larvae begin to exhibit the characteristic colouration of juveniles of this species - overall brown mottled markings with a white stripes running lengthwise along the head. At 3.5 mm the yolk sac is all but gone, fin rays are beginning to appear and the teeth are well developed. By the fifth day the yolk sac has been completely absorbed and by 8.5 mm the fins are fully developed. Growth rate is variable, but generally rapid. Diet A carnivore, feeding mainly on smaller fish as well as crustaceans.
Juveniles take smaller fish fry, smaller crustaceans and aquatic insects.
Angling An exciting and popular target for anglers in northern Australia, Barramundi responds well to lures either cast or trolled. Large minnow pattern lures are popular and productive when fished around snags, mangrove roots rocky outcrops, submerged timber and other heavy cover. Bright metallic gold or bronze a particularly popular lure colours for these feisty fellows. Often known for its spectacular leaps from the water during the fight, the Barramundi justifiably commands respect from those who seek it out. Whilst some excellent specimens have been taken on dead baits, it is not generally a recommended option.
