Economic analysis of carp based culture technologies in selected areas of Bangladesh

Six carp based culture technologies such as, carp-pangas, carp polyculture, carp-golda, pangas monoculture, golda monoculture and nursery have been selected to determine the cost and returns of respective technologies in Bangladesh. The sample farmers selected for these technologies were 55, 100, 65, 50, 51 and 55 respectively and thus the total sample size stood at 376. The study covered 7 districts of Bangladesh, namely, Mymensingh, Bogra, Noakhali, Comilla, Jessore, Khulna and Bagerhat. Both primary and secondary data were used for this study. It was found that farmers used a good number of feeds for the selected technologies and they maintained no standard doses for them. Remarkable differences were found among the prices of different feeds and other inputs used for different technologies in different locations. Prices of all inputs were found to be increasing and this increase was more in recent years compared to previous years. Though all the technologies were found to be profitable, the feed situation was not satisfactory. Except rice polish all the local feeds showed deficit in supply to meet the national demand for the country. If this situation persists and no proper measures are taken to secure the local feed supply, the present development of supplementary feed-based aquaculture would be fully dependent on imported feeds and would not be sustainable in future. This study strongly suggests the corresponding authority to handle the matter with proper attention considering its significant livelihood impact on the economy of the country.
