How to Rig for Giant Trevally (GT)

Caranx ignobilis

Giant trevally are the heavyweight of the trevally family, hunting reef edges, channels, and flats across tropical Australia and the Pacific, including Hawaii. They are famous for smashing surface poppers and for brutal first runs toward the reef, so very heavy tackle and locked drags are used. Most GTs are released, since big fish can carry ciguatera and are valued far more as a sport fish.

Heavy Live Bait Rig

advancedboat · jetty

A big non-offset circle hook is bridled through the nose or eye sockets of a live mackerel, scad, or small tuna with floss, so the bait swims freely and the hook stays clear to set in the corner of the jaw. Fished on heavy line from boats or rocks, it targets marlin, bluefin, kingfish, and giant trevally.
