Grass Carp (Ctenopharyngodon idella) Model


SKU: N/A Categories: ,


The Grass Carp (Ctenopharyngodon idella) is a large herbivorous freshwater carp species native to eastern Asia, with an original range from northern Vietnam to the Amur River on the Siberia-China border. This Asian carp is the only species of the genus Ctenopharyngodon. Grass Carp, together with Bighead, Silver, and Black Carps, make up the culturally important “four famous domestic fishes” used in polyculture in China for over a thousand years, and known as “Asian carp” in the United States.

Grass Carp are cultivated in China for food, but they were also introduced to the southern United States in the late 1960s and 1970s for use as biological control in aquaculture facilities. They have since become one of four invasive Asian carp species threatening to invade the Great Lakes in North America. The other three are bighead carp, black carp and silver carp.
