Abstract

The study evaluated the sustainability, economic and environmental aspects of organic shrimp farming in Bangladesh. The educational level of the household head, the size of the flock, and the farmer’s understanding of organic shrimp production all had a favorable and significant impact on the farmers’ decision to adopt organic shrimp production. Cause-effect-mitigation analysis pointed out that organic shrimp farming could mitigate the adverse effects on environment caused by traditional shrimp farming. Use of chemical fertilizers and hazardous chemicals destroy the natural pond environment as a result overall production often become hampered, the farmers face economic loss and moreover, the biodiversity of that area also destroyed. Organic shrimp farming does not allow any chemical treatment, even artificial feed of shrimps and wild caught PL (post larvae) are used for stocking. This method rather supports the farmers to prepare natural compost and bokashi for regular use in the shrimp farm which does not affect the overall production of shrimp, farmers make profit due to saving of the input cost (chemical fertilizers and hazardous chemicals) and this method is safe for the biodiversity as well. Control or extensive farming system does not use any input, after drained out the pond in some case few farmer (highest 10%) use lime as very low dozes. Stocked both wild catch and hatchery produced post larvae in the pond and gher. The present research tried to find out which shrimp farming practices conserve or protect more biodiversity in the pond and gher. The study suggests that in order to decrease the threat of disease outbreak, good management procedures should be implemented and farmers should be trained to follow the work instructions and principles of organic shrimp production.
