Catch season

A child can catch it in the shallows of a river mouth or harbour with one rod and some worm. The fish grow through autumn, then drop into deeper water for winter.

About

A bottom-dweller that rests on the muddy sand of river mouths, usually around 15 cm but sometimes reaching 30 cm. Its pelvic fins are fused into a sucking disc and its tail fin carries rows of dark spots. It feeds on worms and crustaceans and normally lives just one year. A staple of Edo-style tempura, and autumn goby fishing is a seasonal tradition.

How to catch it

A familiar catch in estuaries and canals. Work the bottom with a pole rig or a light casting rig baited with bloodworm. Late summer through November is when the numbers come.

Chonage (short-cast bottom fishing) from a River mouth

Cut the bait to about a centimetre; anything longer and the fish cannot take it in, so it just strips the hook. In summer they are in the shallows at your feet, and by autumn they have moved a little deeper.

Areas: Tokyo Bay

Waters: Sea of Japan, Northern Pacific coast, Southern Pacific coast, Seto Inland Sea, East China Sea & western Kyushu

Rules

At a river mouth, inland-water rules may apply. Check whether the area falls under a fishery cooperative.
