Giant trevally

This is a regulated fish. See Recreational fishing rules in Queensland - Tidal waters for the current regulations.

Description

This species is the largest species of the Indo-Pacific region. It can grow up to 1.7m (60kg), but is generally caught at much smaller sizes. At maturity giant trevally are 5 years of age and 95-96cm in length. These fish are bluish-silver on the back, sometimes with a yellowish hue. Their sides are yellowish silver, and they have a small oval-shaped patch of tiny scales on the breast, right in front of the ventral fins. The giant trevally lacks any opercular spot behind the eye, and no black blotch appears at the base of the pectoral fin. The upper flanks may be covered by a scattering of small black dots.

Habitat/distribution

The giant trevally, or GT as it is often known, ranges through all Australian warmwaters, into the Northern Territory. It is a marine, pelagic fish, occurring over the tropical continental shelf, with some venturing further offshore into southern waters. Most individuals of this species aggregate in large schools. Larger individuals tend to be solitary, and prefer to feed at night.
