Carp-tilapia polyculture integration with pigs- “enhancing benefits to uplift the economic status of small scaled farmers of Nepal

Abstract

Pig cum fish farming practice with proper management techniques helps to uplift the living standard of Nepalese people. Culture of carp-tilapia polyculture in integration with the pig was conducted for 120 days in 580 m2. The stocking density of fish species was 10,000 fish/ha. The ratio of fish stocked was 5:2:4:1:3:5 (Labeo rohita: Cirrhinus mrigala: Cyprinus carpio: Hypophthalmichthys nobilis: Ctenopharyngodon idella: Oreochromis niloticus), integrated with two pigs. The total weight of fishes was 83.7 kg with a stocking weight of 18.75 kg. The mean harvest weight of L. rohita, C. mrigala, C. carpio, H. nobilis, C. idella, and O. niloticus was 197.3±9.0, 157.4±29.9, 402.2±102.6, 394.3±13.8, 121.5±36.8, and 139.4±20.1 g/fish. The extrapolated GFY and NFY for L. rohita, C. mrigala, C. carpio, H. nobilis, C. idella and O. niloticus was 0.97, 0.19, 1.73, 0.57, 0.27, 0.65 t/ha/yr, and 0.76, 0.15, 1.58, 0.39, 0.20 and 0.30 t/ha/yr respectively. Overall, extrapolated GFY, NFY, survival rate and AFCR were 4.2 t/ha/yr, 3.4 t/ha/yr, 62.93 %, 2.72, respectively. It was found that the B: C ratio of 1.65 can be obtained in carp-Tilapia polyculture in integration with the pig. Thus, it can be concluded that it is an economic enterprise, and can be recommended for small-scale fish farmers of Nepal.
