Sharpbelly

Hemiculter leucisculus

The sharpbelly — the baitiao — is China's most ubiquitous small target fish, found in lakes and reservoirs almost nationwide. It is often confused with a juvenile topmouth culter, but the sharpbelly is much smaller, with a shallower body, a less strongly upturned mouth and no culter-style hump behind the head. A perfect first fish on micro tackle and a classic live-bait species.

Blue-grey back, bright silver sides, no hump behind the head
Complete lateral line curving down along the flank

Habits

A staple forage fish for culter, bass and mandarin fish

How to catch them

Small-hook float fishing mid-water Lake

Rig: Light float rig with fine line and a size 14-18 hook, bait set mid-water over open lake water

Bait/lure: Tiny dough pellets, maggots, small worm pieces

Key tip: Chum lightly with bran or rice and keep the bait moving slowly — sharpbelly lose interest in a static bait.

Micro spoon lure fishing Lake

Rig: Ultralight rod, 2-4 lb line and a 1-2 g spoon retrieved steadily just under the surface

Bait/lure: 1-2 g spoons, tiny spinners

Key tip: Cast to dimpling schools at dawn; a fast, shallow retrieve draws instant strikes.
