Abstract:
Till recently, carp seed rearing and farming at any scale was highly profitable because of the low cost for the inputs. But it no longer continues, as the cost of basic inputs like cow dung, poultry manure, ground nut cake, rice bran and land costs are increased by many folds, while the gate value of the fish seed and fish remained almost constant. To know the scale of economy and present economics of the fish rearing at different stage, the assessment was carried out in 258 villages of Southern Karnataka. It is found out that fish seed rearing for 50 days, the Benefit Cost ratio (BC ratio) in catla 1.23, rohu 2.04, common carp 1.65 and grass carp 2.82. The return on investment (RoI) is high in grass carp (103.10) followed by rohu (87.59), common carp (60.46) and catla (49.96). In fish culture for 10 months period, the BC ratio in feed-based farming was 1.63 as against 1.89 in conventional feed-based system and 2.01 in extensive method. The RoI was 25.44, 17.22 and 10.14 in feed based, conventional feed and extensive method respectively. While input rates may differ across locations, this study provides an overview of the economic trends, enabling farmers and entrepreneurs to strategically plan their scale of operations according to available resources and capital.
