Fin's Fish Guide
The Grass carp (Ctenopharyngodon idella) is a freshwater fish of the family Cyprinidae that grows up to 150 cm.
Originally in the large rivers of East Asia, including China and the Amur basin.
Description
The grass carp is a large, plant-eating cyprinid of the family Cyprinidae that can reach about 150 cm and tens of kilograms. The elongate, fairly rounded body is grey-green with a silvery sheen and large scales with dark edges; the mouth is terminal and the fish lacks barbels. The species is native to the large rivers of East Asia but has been stocked worldwide because it eats large amounts of aquatic plants and can keep overgrown waters open. In many areas, including the Netherlands, it does not reproduce on its own and must be restocked. It grows fast and, by overgrazing water plants, can change ecosystems profoundly.
