Know it

Spot it, size it up and learn its habits.

Identification

A long, torpedo-shaped snapper, gray-green to blue-gray all over, with a big mouth with prominent canine teeth, a deeply forked tail and a groove in front of the eye. Called uku in Hawaii.

Typical size

5–20 lb.

Maximum size

About 3½ ft and 34 lb (15.4 kg).

Diet

Fish, squid, shrimp and crabs.

Behavior

More of a mid-water hunter than most snappers: cruises over reef edges, ledges and sand channels, and will chase lures up off the bottom. Can live over 30 years.

Find it

Where, when and how deep to look.

Where to find it

Found from Hawaii, Guam & Northern Mariana Islands, American Samoa, South Pacific Islands & Papua New Guinea, Queensland & the Great Barrier Reef, Northern Territory & Western Australia, Indonesia (Bali, Komodo, Raja Ampat, Sulawesi), Philippines, Japan & South Korea, East Africa & Indian Ocean Islands and Red Sea & Arabian Gulf (Egypt, Oman, UAE). Reef slopes, banks, channels and lagoons throughout the Indo-Pacific; Hawaii's Penguin Bank and the Guam banks are well known.

Habitat

Reef slopes, banks, channels and lagoons throughout the Indo-Pacific; Hawaii's Penguin Bank and the Guam banks are well known.

Depth

Surface to 600 ft; mostly 30–300 ft.

Fishing depth

60–250 ft.

Best season

All year; spring and summer (May–August) is peak in Hawaii.

Best time

Daylight hours, especially early morning and late afternoon.

Best tides

Moving water: the hours around the tide change, when current pushes over the reef edges and bait gets swept along.

Best weather / conditions

Calm to moderate seas; light wind against the current stirs up bait. Watch for storms and cyclone season.

3

Bait & gear

What to tie on and what to throw.

Best bait

Live or whole dead small fish (opelu, akule), squid and cut bait, with chum.

Best artificial lures

Slow-pitch and speed jigs, soft plastics and deep-trolled plugs.

Tackle setup

Medium-heavy jigging or conventional rod (30–50 lb).

Hook size

5/0–8/0 circle hooks.

Line

40–65 lb braid.

Leader

50–80 lb fluorocarbon.

Catch it

Step by step, from first cast to landing.

Step-by-step: how to catch it

  1. Go where it lives: Reef slopes, banks, channels and lagoons throughout the Indo-Pacific; Hawaii's Penguin Bank and the Guam banks are well known.
  2. Rig up: Medium-heavy jigging or conventional rod (30–50 lb). 50–80 lb fluorocarbon.
  3. Pick your bait: Live or whole dead small fish (opelu, akule), squid and cut bait, with chum. Lures: Slow-pitch and speed jigs, soft plastics and deep-trolled plugs.
  4. Fish it: Drift or anchor over ledges and drop-offs with chum, and work jigs or baits from the bottom up through mid-water.
  5. Time it: Daylight hours, especially early morning and late afternoon. Moving water: the hours around the tide change, when current pushes over the reef edges and bait gets swept along.
Fishing techniques

Drift or anchor over ledges and drop-offs with chum, and work jigs or baits from the bottom up through mid-water.

BigJoe's tip

Uku are line-shy in clear water: drop down to a lighter fluorocarbon leader if the bites stop.

Catch and release

Catch and release: wet your hands, keep the fish in the water when you can, and release it quickly. Use circle hooks and a dehooker.

Clean & cook

Is it good to eat, and how to prepare it.

Edibility

Excellent eating — one of the best-tasting fish in its range.

Cleaning

Bleed and ice it right away. Fillet, then remove the skin and any dark bloodline.

Cooking suggestions

Excellent: firm white meat, great as sashimi, fried, steamed or grilled.

6

Stay safe & legal

Safety, rules and taking care of the fishery.

Safety warnings

Big reef fish from some tropical areas can carry ciguatera (a fish poison that cooking doesn't destroy); ask locals which fish and sizes are safe to eat. Sharp spines and gill covers — handle with a towel or gloves.

Regulations

Hawaii has a minimum size for uku; other islands and countries set their own rules. Check current rules. Rules differ by island: Hawaii, Guam, the Northern Marianas and American Samoa need no license for recreational saltwater fishing, but size and bag limits, closed seasons and marine preserves apply; other Pacific nations require permits, and many reefs belong to villages, so ask permission.

Conservation

Keep only what you'll eat and release the big breeders; wet your hands, support the fish's belly and get it back in the water fast.
