Catch it

Step by step, from first cast to landing.

Step-by-step: how to catch it

  1. Go where it lives: Sandy beaches and bays of Japan, Korea and China.
  2. Rig up: Long surf rods (13–14 ft) for nage-zuri casting, or a light boat rod. 3–5 lb monofilament snoods.
  3. Pick your bait: Sandworms (ishigokai and aoisome). Lures: Rarely used.
  4. Fish it: Cast a multi-hook worm rig far out over sand and drag it back very slowly to find the schools.
  5. Time it: Daylight hours, especially early morning and late afternoon. The rising tide and the top of the tide, when gutters and holes along the beach fill with water.
Fishing techniques

Cast a multi-hook worm rig far out over sand and drag it back very slowly to find the schools.

BigJoe's tip

When you get a bite, keep dragging slowly — kisu travel in schools, and more will bite on the same cast.

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: Japan's classic tempura fish.

6

Stay safe & legal

Safety, rules and taking care of the fishery.

Safety warnings

Harmless; watch for weever-like stingfish and jellyfish on summer beaches.

Regulations

No license at sea; local beach rules apply. Sea fishing in Japan and South Korea needs no license for visitors, but local fishery cooperatives set rules; rivers and lakes require a day or season ticket (in Japan, a yugyoken) from the local fishery cooperative, and many rivers have closed seasons.

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.
