On the growth of grass carp, Ctenopharyngodon idella Val. in composite fish culture at Kalyani,West Bengal (India)

The Central Inland Fisheries Research Institute, Barrackpore, under its “All India Co-ordinated Research Project on Composite Culture of Indian and Exotic fishes” has been conducting experiments since 1971 in different parts of India to develop formulae of species combination of fishes whereby fishes feeding in different zones of pond water are selected and cultured together to increase production in pond culture operations. These experiments have indicated that grass carp not only controls aquatic weeds but also at the same time grows very fast and thus it is one of the best culturable fish if its feeds are available.
