Fishing methods

Sabiki fishing

A multi-hook rig imitates tiny prey while a bait basket releases a small trail of shrimp. Fish vertically at a permitted pier rather than swinging exposed hooks through a crowd.

Ajing — light lures for horse mackerel

Small jigheads and soft plastics let you search for horse mackerel at a precise depth. Current and fall time matter as much as lure colour.

Detailed Japanese species notes

マアジより細長く丸い断面の体。尾の直前にある小離鰭が決め手で、背側・腹側の両方を確認します。ゼイゴがあるだけではマアジと区別できません。

魚を針から外すときはひれとゼイゴに注意。赤身魚なので釣ったら早く冷やし、常温に置かない。
