POTENTIALS AND PROBLEMS OF FRESHWATER PRAWN CULTURE IN THE NORTHERN FISHERIES ZONES OF BANGLADESH (Pages : 42 - 47)
J.M.A. HAQUE, M.G. HOSSAIN AND M. WAHIDUZZAMANStudies were conducted Potentials and problems of freshwater prawn culture in the northern fisheries zones of Bangladesh with objectives of knowing the present status of prawn culture, identifying the problems of prawn culture and to prioritize the major potential technologies to be used for production improvement. The studies were covering 9 Agro-Ecological Zones of 6 Districts of Rajshahi and Rangpur Divisions. The methods included technical survey, group discussions and case studies. The results showed that the status of the ponds, water bodies as per prawn culture potentially have problems involving both technical and extension reducing the production up to 40% of the expected potential. Rajshahi ponds had more calcareous (69% response), silty clay loam soils (58% response), while the Rangpur ponds had acidic soils (62% response), having sandy loam soils (61% response). Higher scores were given for production and marketing of post larva (PL) and juvenile seeds. For such reasons mean while 20-40% farmers discontinuing their farms of which 46% due to input factor i. e. seed non-availability along with its higher prices. It was concluded more liming should be done to keep the water condition favorable specially in the Rangpur division for prawn culture. Hatcheries should be established and DOF extension support should be increased to the prawn farmers. Steps should be taken to reduce price of prawn seed and quality feed. Existing hatchery's prawn production should be increased providing technicians. Local depot owner (Aratdar) should be established in local prawn cultivation supplying PL and feed through market chain.Download
