Performance of Amur common carp breed in east Siang District of Arunachal Pradesh

Multilocational trials to study the growth performance of Amur common carp, Cyprinus carpio in East Siang District of Arunachal Pradesh were conducted for a period of 12 month. Amur common carp showed 20 per cent faster growth than the existing stock of common carp in polyculture system with three Indian major carps viz., Rohu (Labeo rohita), Catla (Catla catla), Mrigala (Cirrhinus mrigala) and two Chinese carps viz., Grass Carp (Ctenopharyngodon idella) and Silver carp (Hypophthalmichthys molitrix). Supplementary feeding of oil cake and rice bran with a mixing ratio of 1:1 was done. The pooled up average growth of the Amur common carp and locally available common carp from the experimental locations were recorded as 543.3g and 451.6g, respectively. Moreover 5.2 per cent higher slaughter value was observed in Amur carp as compared to locally available stock.
