Fishery Science Popularization - Grass Carp
English name: Grass carp
Local names: Huan fish, grass root
Taxonomic status: Cypriniformes, Cyprinidae, Ctenopharyngodon
Morphological characteristics: Elongated body, cylindrical in shape, rounded belly without a keel, tail laterally compressed. Top of head fairly broad. Snout short and bluntly rounded. Mouth terminal, no barbels. Scales fairly large, round. Dorsal fin iii-7; anal fin iii-8; lateral line scales 36~48. Body is tea-yellow, belly grayish-white, pectoral and pelvic fins slightly grayish-yellow. Other fins are darker in color.
Ecological habits: Prefers to inhabit the middle and lower layers of rivers, lakes and other waters, as well as nearshore areas with abundant aquatic plants. Lively in temperament, swims swiftly, often forages in groups, and grows quickly. A typical herbivorous fish; in artificial culture it can feed on compound feed. A river-lake migratory fish that produces floating eggs.
Geographical distribution: Native to the Yangtze River system. Introduced to Ningxia in the 1950s.
Economic value: One of the leading species in aquaculture, with very high economic value. However, in natural waters the stocking density should be controlled to avoid eutrophication of the water body.
