A highly prized open-water and reef-edge species. Uku are fast, powerful, and excellent eating. They school in mid-water above reef structures and drop-offs. One of the most sought-after spearfishing targets on the Big Island.
Uku school in mid-water and are best approached with a slow, patient descent. They are curious and will often circle a stationary diver. Use a long gun (110cm+) and aim for the head. Best hunted at deeper reef edges and channel mouths.
No statewide size or bag limit. Ka'ūpūlehu Marine Reserve: Uku may be taken by hook-and-line seaward of 20 fathoms only.
Non-residents age 15+ also need the Hawaiʻi nonresident marine fishing license (HAR 13-74-11) — buy online or see our regulations guide.
