About the Ulua

The ultimate Big Island trophy fish. Giant Trevally are powerful, fast, and highly prized by spearfishers. They patrol reef edges, channel drop-offs, and open water. Require stealth and a well-placed shot — they will test your gear.

How we hunt them

Approach from down-current and use the reef structure as cover. Ulua are curious — a slow, deliberate approach often works better than chasing. Target the channel edges at dawn and dusk. Use a reel gun with 200+ lb shooting line for large fish.
