Status of existing integrated aquaculture system of some areas in Sadar upazila of Dinajpur district, Bangladesh

This study was conducted to know the current status of integrated aquaculture system in Dinajpur Sadar Upazila, Bangladesh. For this purpose, randomly selected 100 integrated aquaculture farmers were interviewed through a pre-tested well-structured questionnaire from February 2019 to August 2019. Average cost and income of rice-fish culture (34 farmers) were 2.08 ± 1.96 and 6.61 ± 6.23 for fish; 0.28 ± 0.26 and 1.22 ± 1.15 for rice, in vegetable-fish culture (47 farmers) 7.05 ± 1.76 and 22.35 ± 5.59 for fish; 0.41 ± 0.06 and 1.59 ± 0.26 for vegetable, in fruit-fish culture (4 farmers) 1.07 ± 0.12 and 3.43 ± 0.4 for fish; 0.52 ± 0.12 and 1.44 ± 0.33 for fruit, in poultry-fish culture (10 farmers) 5.18 ± 4.8 and 16.43 ± 15.21 for fish; 3.09 ± 2.61 and 3.62 ± 3.07 for poultry and in duck-fish culture (5 farmers) 1.19 ± 0.57 and 3.89 ± 1.87 for fish; 0.39 ± 0.2 and 0.96 ± 0.49 for duck, respectively. Among them fruit cum fish culture showed significant (P<0.05) value of fish production. Maximum fish production (11.11 ton/ha) and highest combine net profit (10.30 lac Tk/ha) were found in duck-fish culture. As a secondary crop, poultry showed highest net profit (21.4 lac Tk/ha) during the research. It can be concluded that farmers get benefited from integrated aquaculture using minimum amount of cost and can improve their economic conditions.
