Economic analysis of floodplain aquaculture at Daudkandi upazilla in Comilla

Abstract

An economic anylysis was made to determine the cost of fish production in the floodplains at Daudkandi Upazilla in Comilla district during the period form January to April, 2007. Survey method was followed to collect data from 20 floodplain aquaculture projects. The projects record books and personal interviews of the NGOs and Fisheries officers were the main instruments of data collection. Statistical tools such as: range, mean, standard deviation and percentage were employed for analysis of data. The Cobb-Douglas production function model was used to estimate the values of co-efficients and related statistics of production function of fish culture in floodplains. Out of eleven explanatory variables, seven co-efficients had positive sign while only four co-efficients showed negative sign. The co-efficients bearing positive sign i.e., embankment construction, nursery and land lease, fertilizer and lime, fingerlings, feed, labor and staff wages and miscellaneous cost made positive impact on the farm income, while the co-efficients having negative sign i.e., area of floodplain, Office management, compensation and harvesting and marketing cost decreased the farm income. Summation of the production co-efficients i.e., return to scale (∑bi) was found 1.023 which implies that per one taka investment in floodplain fish culture will give rise to a profit of Tk. 1.02. The value of R 2 was found 0.892, which means that the variations in farm income could be explained to the extent of 89.2% by the included variables. The remaining 10.8% variations could not be accounted for by the multiple regression analysis. Average fish production in the selected floodplains was 2920.43 kg/ha of which production of cultured fish and indigenous fish was 2697.35 and 223.08 kg/ha respectively. The cost of fish production, total return and net income were estimated Tk. 1,153,08.55, 1,76,385.49 and 61,076.94 /ha. respectively. Benefit cost ratio was found 1.53.

Management practices in the beel aquaculture system at Rajshahi, northwest Bangladesh

“…Total fish production for the six months culture periods was 2622.15 kg/ha. Chandra et al (2010) recorded 2920.43 kg/ha fish production in beel aquaculture from Daudkandi, Cumilla, Bangladesh which is higher than the production of present study. The parasitic infection could be linked with the lower fish production in the present study as compared to the earlier study.…”

Aquaculture practices in two seasonal floodplains of Bangladesh

“…According to Bayley (1988) the maximum potential yields is more highly exploited tropical floodplains at 110-160 kg/ha/yr. Most of the floodplains in Bangladesh are not cultured in a plan way as like as Daudkandi area floodplain shown by recent research (Chandra et al 2010).…”

“…3389.82/ha on average which was 1.62 % of the total investment for fish culture purposes in Khirai floodplain whereas it was 3.45 % in Angrail floodplain. According to Chandra et al (2010), as the floodplain area had lower land elevation, it became flooded regularly depending on the water level in the adjacent rivers. For aquaculture project to select floodplain area, it required encircling the area by constructing good embankment and sluice gates.…”

Community participated management of chaur (floodplain) fisheries: A case study of mahisar chaur in Samastipur district of Bihar, India

“…The productivity of the chaur was 243.81 kilogram per hectare per year. Chandra et al (2010) found average fish production of 2920.43 kilogram per hectare per year from beels of Bangladesh whereas production from the chaurs was 243.81 kilogram per hectare per year, indicates poor management of capture fishery in chaurs of Bihar in comparison to Bangladesh. It was also observed that the size of captured fishes were small, which indicates the existence of potential to increase the yield from chaur by extending the period of rearing of juvenile fishes.…”
