Aori-ika (Bigfin Reef Squid): A One-Year Life and Two Eging Seasons

Aori-ika (bigfin reef squid, Sepioteuthis lessoniana) is called the “king of squid” in Japan: delicious, hard-pulling, and catchable on lures (egi). Those three together created a whole genre — eging — with dedicated rods and reels. And few targets reward understanding their biology more, because this squid lives only about one year.

Basic data

A one-year life explains everything

Hatched in spring to early summer → grows fast in summer → reaches catchable size in autumn → grows large over winter → spawns and dies the next spring. That gives eging two completely different seasons.

Because there are no “come back next year bigger” squid, taking too many small autumn squid means fewer adults next spring. Many anglers release squid with a mantle of 15 cm or less.

Three types

• Shiro-ika type: the most common; most squid caught are this.
• Aka-ika type: grows larger; found on coasts facing the open ocean.
• Kua-ika type: small; more common in southern waters.

You rarely need to tell them apart, but they explain why unusually large squid sometimes turn up.

Hugging, not biting

Unlike fish, aori-ika do not “eat” the egi — they grab it with their long tentacles and hug it with their arms. So the bite is subtle: slack line suddenly stops, the line moves sideways, or just weight. And they grab it on the fall. Jerks make the squid notice the egi; the fall makes it hug. Understand that, and long pauses after jerking make sense. Softer rods give a more stable fall and fewer lost squid.

Landing, ink and the jig spikes

1. Swinging heavy squid up tears them off — the egi’s spike rings only hook the arms. Use a net for squid over about 300 g, and never forget it in spring.
2. Let it ink first — squid squirt ink and water when landed. Do not point it at your face; let it ink at the surface first.
3. The spikes have no barbs — easy to remove, but easy to stick in your finger with a struggling squid. Wait until it calms down.

Tackle

For one setup for both seasons: 8.6 ft, PE 0.6 and an egi-3.5-rated rod. Eging from beaches is another option — fewer people and good-sized squid.

Eating

Aori-ika is considered in a class of its own: thick, sweet flesh with a unique sticky texture as sashimi.

• Dispatch on the spot — spike between the eyes; the body turns white instantly when done right.
• Remove the ink to avoid an inky cooler.
• Keep fresh water off it — ice in bags or bottles.
• Rest a day for sweetness — crunchy on the day, sweet and sticky the next.
