Description

The asp is a large, slender predatory cyprinid of the family Cyprinidae reaching about 1.2 metres. The silvery, streamlined body has a large, obliquely upturned mouth; unlike true predators the asp lacks jaw teeth and seizes prey with a powerful, sucking gulp. The species lives in large rivers, lakes and reservoirs of central and eastern Europe, including slightly brackish water. Young fish eat insects and school, but large fish hunt actively and often solitarily in open water for small schooling fish such as bleak and roach, sometimes with spectacular surface strikes. In spring it spawns over gravel. The asp is a valued, sporting predator for angling.
