Common carp are benthic feeders and root in sediment for food items. Their barbels may help to feel for food embedded in the sediment, like plant tubers or annelids. [18] Carp pick up sediment by generating suction and mouth the content to identify and select food items by taste and size.

Fish used in this system include catla and silver carp (surface feeders), rohu (a column feeder), and mrigal and common carp (bottom feeders). Other fish also feed on the excreta of the common carp, and this helps contribute to the efficiency of the system which in optimal conditions produces 3000–6000 kg of fish per hectare per year. [36]
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 ...

Cyprinidae is the largest and most diverse fish family, and the largest vertebrate animal family overall, with about 3,000 species ; only 1,270 of these remain ...
Different species feed on different foods and occupy different niches in the ponds. In this way, the Chinese were able to simultaneously breed four different species of carp, the mud carp, which are bottom feeders, silver carp and bighead carp, which are midwater feeders, and grass carp which are top feeders.
Grass carp require long rivers for the survival of the eggs and very young fish, and the eggs are thought to die if they sink to the bottom. [ 6 ] Adult grass carps feed primarily on aquatic plants , both higher aquatic plants and submerged terrestrial vegetation, but may also eat detritus , insects and other invertebrates .
