Catch season

It becomes active as the water warms and turns up constantly in summer chonage sessions aimed at whiting. Below about 15 degrees it buries itself in the sand and stops feeding, so the season is confined to early summer through autumn.

About

A wrasse often caught over sandy ground near rocky shores. Males are blue-green and females reddish brown - a striking difference. At night it buries itself in the sand to sleep.

On the bottom, and specifically where sand meets rock or weed rather than on clean sand. Most bites come as the rig is dragged in towards the structure.

How to catch it

Fish it with a short cast and a slow drag over sand broken by rock and weed, with a piece of worm on the hook. It sits closer in than the whiting, near the structure. It feeds by day; after dark it buries itself and stops.

Chonage (short-cast bottom fishing) from a Breakwater / Pier

If these keep coming while you fish for whiting, your rig is passing close to rock or weed within the sand. Work the same line if you want numbers, or move the cast five metres along to find clean sand and get back to the whiting.

Areas: Osaka Bay

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

Surf casting from a Sandy beach

In surf fishing it comes from around isolated rock offshore, so if the bait keeps disappearing, cast away from the structure. Males are blue-green and females reddish brown, different enough to look like two species from the same patch of sand.

Handle with care

This fish is dangerous to handle bare-handed.

Sharp teeth Minor ・ Where: 口

Small but pointed teeth sit at the front of the mouth. It often swallows the bait and the hook with it; rather than dragging the hook back out, cut the leader and release the fish if the pliers cannot reach.

Eating

Eating quality 3/5 ★★★☆☆

Dismissed as a nuisance around Tokyo, it is valued as a summer fish in the Inland Sea and Kansai. The flesh is soft, which suits grilling, deep-frying, or a vinegar marinade.

Best eating: June–August
