Economic feasibility of composite fish culture (CFC) in East Siang district, Arunachal Pradesh

An investigation was carried out to evaluate growth performance, yield and economic analysis of Composite Fish Culture (CFC) during 2016–2018 by conducting four multi-locational trials at farmers’ field. Six species of carps viz. Rohu (Labeo rohita), Catla (Catla catla), Mrigala (Cirrhinus mrigala), Grass Carp (Ctenopharyngodon idella), Common carp (Cyprinus carpio) and Silver carp (Hypophthalmichthys molitrix) were stocked in a ratio 2 Catla: 2 Rohu: 1.5 Mrigal: 2 Silver carp: 1 Grass carp: 1.5 Common carp in the rate of 7000 numbers per hectare. The recommended best management practices for CFC were applied during the trial. The average productivity of the fishes from experimental locations were recorded as 19.4 q, 20.2 q and 19.9 q respectively whereas the average total cost of production per hectare was Rs. 1, 46,667. The benefit-cost ratio of 2.16 reflected the adoption of good management practices in production of fishes resulting CFC as a profitable venture.
