BigJoe's tip

Golden trevally follow feeding stingrays: cast just ahead of the ray and you'll often hook the trevally behind it.

Catch and release

Catch and release: wet your hands, keep the fish in the water when you can, and release it quickly. Use circle hooks and a dehooker.

Clean & cook

Is it good to eat, and how to prepare it.

Edibility

Good eating when fresh.

Cleaning

Bleed and ice it right away. Fillet, then remove the skin and any dark bloodline.

Cooking suggestions

Good when bled: firm, white-pink meat for sashimi or grilling.

6

Stay safe & legal

Safety, rules and taking care of the fishery.

Safety warnings

Sharp scutes near the tail; ciguatera risk from big reef fish in some islands. Watch for stingrays when wading.

Regulations

Bag and size limits in Australian states and Hawaii (where it's called ulua pa'opa'o and papio when small). Check current rules. Licenses and rules differ by country across the Indo-Pacific: Australia's states, Asian countries and the Pacific islands all set their own bag limits, size limits and marine park zones. Check the local rules or fish with a licensed charter.

Conservation

Keep only what you'll eat and release the big breeders; wet your hands, support the fish's belly and get it back in the water fast.
