Assessment of organic shrimp farming sustainability from economic and environmental viewpoints in Bangladesh.

The study assessed the economic, environmental and sustainability issues of organic shrimp farming in Bangladesh. Following stratified random sampling technique, 60 farmers were interviewed from several villages of Assasuni upazila under Satkhira district. The study revealed that productivity of organic shrimp per hectare was 383 pound and benefit cost ratio was 1.91 which meant that organic shrimp farming was highly profitable. Educational level of household head, gher size and knowledge on organic shrimp production had positive and significant influence in adopting organic shrimp production by the farmers. Cause-effect-mitigation analysis pointed out that organic shrimp farming could mitigate the adverse effects on environment caused by traditional shrimp farming. Appropriate climate and environment for organic shrimp culture was found as major strength and comparative profitability than traditional shrimp production was found as major opportunity of organic shrimp production. The study confirmed sustainability of organic shrimp production from the standpoint of consuming energy, protecting environment, economic feasibility and social/political equity. The study recommends that farmers should be trained to follow the work instructions and principles of organic shrimp production and the application of good management practices (GMPs) should be ensured for reducing the disease outbreak risk.
