Economic analysis of different aquaculture systems in Mizoram

Economic analysis of different aquaculture systems in Mizoram was performed using interview schedule from 120 farmers. Results indicated that unitary system was practiced for 8-10 months with higher cost of culture (Rs 2.93 lakh/ha). Paddy-cum-fish culture farmers received higher average net income (Rs 0.66 lakh/ha/year). B:C ratio of paddy-cum fish integrated system (1.32), pig-cum-fish integrated system (1.29), and unitary system (1.15) indicated economic feasibility and profitability in all three aquaculture systems. However, integrated fish farming was more profitable than unitary farming, and among the three systems, paddy cum fish culture was found to be the most profitable system.
