Description

The piscivorous chub is a slender, predatory cyprinid of the family Xenocyprididae reaching about 44 cm. Unlike most cyprinids it has a large mouth with wavy jaw edges that interlock, with which it holds prey. Outside the breeding season it is silvery with faint vertical bars, but breeding males colour up vividly with blue-green and red-orange tints and develop tubercles. The species comes from East Asia and lives in schools in clear rivers and lakes with flowing water. It hunts small fish, insects and crustaceans. It is a valued small sport and food fish and an unusual fish-eater among the cyprinids.
