Research notes, Hawaii region
Ulua and papio support the most popular recreational fishery in the state (DAR). Fish stay in small home ranges in winter and travel up to 38 km along the coast during the summer spawning season, spawning February-September with a peak May-July just before full moons. Researchers have recommended protecting that peak. Regulatory: DAR sets minimum size and bag limits for ulua and papio; check current rules.
Seasons and limits in these notes are background. The regulations below and the regulator’s own page govern.

How and where it feeds
- Water temperature
- Feeds from 70°F to 88°F, best between 74°F and 82°F.
- Water depth
- 3 to 200 ft of water.
- Structure
- Point, ledge, reef, channel, jetty, beach and estuary, in that order of preference.
- Tide and current
- Prefers incoming tide and high tide, with moderate current.Shore anglers generally favor rising and high tides that push water and bait over ledges and reef flats. This rests on traditional practice and angler reports, not published studies.
- Light
- Bites best around dawn and dusk; feeds at night too.
- Pressure
- Little response to pressure changes.
- Wind and sea limits
- 20 kt of wind and 5 ft of sea. The Waterlands engine scores hours down as conditions pass them.
Tackle and technique
Ulua hunt reef edges, rocky points, harbor mouths and sand channels from the shoreline out to deep ledges. Shore anglers slide an eel, tako or crab down a heavy anchored line and fish through the night, while casters throw poppers and plugs over reef edges at dawn and dusk. The first run heads for the rocks, so use heavy line and a tight drag.
- Methods
- slide-bait fishing, whipping (casting plugs), shore casting, trolling, jigging
- Lures
- poppers, stickbaits, swimming plugs, metal jigs
- Bait
- eel (puhi), octopus (tako), crab, live reef fish, squid
