Cirrhinus molitorella
Cirrhinus molitorella (mud carp or dace) is a species of ray-finned fish in the genus Cirrhinus found mainly in southern China and Vietnam. HistoryThe mud carp is a native Asian freshwater fish with a broad distribution from the Mekong River to the Pearl River deltas, inhabiting lakes, rivers and reservoirs.[citation needed] Mud carp cultivation was introduced to China during the Tang dynasty (618–907 AD) as a substitute for common carp, as the common carp was forbidden to fish due to a ban.[2] Chinese aquaculture farmers adapted by raising mud carp, which were bottom feeders, in polyculture with top-feeding grass carp, while silver carp or bighead carp lived and fed in the middle depths.[3] HabitatMud carp is typically a subtropical fish.[4] The mud carp is found in the mud and Mekong River and Pearl River delta, as well as bodies of freshwater along these two rivers.[citation needed] In China's Guangdong province and Guangxi autonomous region, mud carp makes up about 30% of the freshwater fish population.[5] The fish has been introduced to Indonesia, Singapore, Japan, Taiwan, and Hong Kong.[2] Within China the fish is raised on fish farms.[citation needed] DispersionThe mud carp is native to Southern China and parts of Mainland Southeast Asia. It is present in major river systems such as the Pearl River, Red River (China/Vietnam), Mekong River, and Chao Phraya River.[2] DietMud carp is an omnivore and mainly consumes water plants or insects. Farm raised carp are fed pellets.[citation needed] Culinary useDue to low cost of production, the fish is mainly consumed by the poor and locally consumed; it is mostly sold live and eaten fresh, but can be dried and salted.[2] Increased fishing has threatened the population of mud carp.[1] The fish is sometimes canned (typically as fried dace with salted black beans) or processed as fish cakes, fish balls [6] or dumplings. They can be found for retail sale within China and throughout the Chinese diaspora.[2] Canned dace from China has periodically been found to carry traces of malachite green, a carcinogenic antimicrobial banned for use in food.[7][8][9] See alsoReferences
