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. They take stealth and a well-placed shot, and 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.

Rules & regulations

Minimum size 10 inches (16 inches to sell). Bag limit 20 per person per day, all ulua and pāpio species combined, including ʻōmilu. In the Kailua Bay FMA, spearing is allowed only in Zone B, not the inner Zone A by the pier.
