Habitat and season

Shallow sand and mud, notably in the Seto Inland Sea.

Recorded fishing season: Sep · Oct
Scientific name: Amphioctopus fangsiao
Japanese name: イイダコ

Months are a broad guide, not a current catch forecast. Region, water temperature and local closures can change the season.

Fishing methods

Octopus jig fishing

Bottom jigs are moved a short distance to attract an octopus. Local fishing rights and the boat’s rules must be checked first.
