Grass Carp

Grass CarpThe grass carp, Ctenopharyngodon idella, also known as the white amur, was imported into Alabama and Arkansas, from eastern Asia in 1963 to control aquatic vegetation. The grass carp has been reported to eat 45 kg (99.2 lbs) of vegetation a day! In Asia, grass carp usually occupy large rivers, but also thrive in ponds and rice fields. Although some say the flavor of the flesh of the grass carp has a strong algal flavor, the market for the fish as food is high in some areas. Grass carp are known to compete for food with invertebrates such as crayfish, and other fish species, and causes significant changes in phytoplankton, invertebrate communities, interfere with reproduction of other fish, modify habitat by destroying vegetation and water quality, and much more. Grass carp can grow to be about 4 ft. and 40-50 pounds.
