Abstract
A field survey through questionnaire was conducted in rice-prawn (Macrobrachium rosenbergii)-fish culture ghers in six villages of Khulna, Satkhira and Bagerhat districts of south-west Bangladesh during March to December, 2008 to assess present culture practices. About 10-25% of the total area of land was converted for building canals and dikes and the remaining area were used for rice cultivation. Boro with prawn and fish appeared to have positive impact on the economic return as well as on the livelihood of the farmers. After harvesting rice, total area were used for prawn and fish culture. Cost benefit analysis revealed that the seed cost of prawn was the highest variable cost. Higher seed cost of prawn and fish can be reduced by ensuring the available supply of seed in proper time. The average Net Return (NR) was BDT 72,395±4,6943 ha-1yr-1 and the Rate of Return (RR) of the rice-prawn-fish farming was 14.64%. Compared with mono crop culture system, the rice-prawn-fish integrated farming in ghers appeared to be economically viable, socially acceptable and environmentally sustainable.
