What special fishing regulations apply at Hilo Bay?

Hilo Bay carries 4 special-regulation overlays that override Hawaii's statewide 2026 rules, covering Bonefish (ʻōʻio), Giant trevally (ulua / papio), and Moi (Pacific threadfin). One of them reads: "Big Island east windward; mixed reef + nearshore pelagic; papio + ulua + bonefish (ʻōʻio) + mountain stream mouths; HAR Title 13 marine rules apply; Wailoa Sampan Basin charter base." Every overlay on this water body is listed in full above.

Do I need a fishing license to fish Hilo Bay?

Yes. Hilo Bay is in Hawaii, so a valid Hawaii fishing license is required just as it is anywhere else in the state, issued by Hawaiʻi Department of Land and Natural Resources (DLNR) — Division of Aquatic Resources (DAR). The special regulations on this page change the bag, size, slot, or gear rules for Hilo Bay; they do not waive the license requirement. Free-fishing days and youth exemptions follow the statewide Hawaii rules.

Do Hilo Bay's special rules replace Hawaii's statewide limits?

Only where they conflict. Hawaii's statewide 2026 regulations apply on Hilo Bay by default; the overlays above replace the matching statewide rules for the species or gear they name, while everything not specifically overridden still follows the statewide rule. When a water-body rule and the statewide rule disagree, the water-body rule wins.

Which species have special rules on Hilo Bay?

Bonefish (ʻōʻio), Giant trevally (ulua / papio), and Moi (Pacific threadfin) have a water-body-specific rule on Hilo Bay, each linking to its full Hawaii regulations above. Species not listed here follow the statewide Hawaii limits.
