abstract
Integrated fish cum pig farming experiments were carried out with the prime objective of developing a suitable strategy of low cost aquaculture in bigger fish ponds of ≥0.5ha. The experiments were conducted at the pig density of 30, 40 and 50 nos. ha-1 keeping the fish density constant at 8500nos. ha^-1. The six species of carp polyculture viz., catla, Catla catla, rohu, Labeo rohita, mrigal, Cirrhinus mrigala, silver carp, Hypopthalmichthys molitrix, grass carp, Ctenopharyngodon idella and common carp, Cyprinus carpio were used in the study. The best fish production among all the components of integrated fish and pig farming was achieved in treatment T₃ (50 pigs ha^-1) which was reported to be 2923.22 kg ha^-1 yr^-1. Grass carp recorded the highest growth of 2.33kg in both treatments T₁ and T₃, followed by silver carp 1.58±0.12 kg in treatment T₃. The physico-chemical parameters were recorded throughout the culture period of 1 year which is within the optimal range for fish culture.
