Suitable Site Selection of Shrimp Farming in the Coastal Areas of Bangladesh Using Remote Sensing Techniques

TARGET GROUP: FARMERS

OBJECTIVES

·        To develop an operational model for selecting a suitable site for shrimp farming-based business development using Remote Sensing Techniques.

SUMMARY

Bangladesh is a vast delta having 14.2 million ha, of which roughly coastal brackish waters cover 17%. At present only 5% of the coastal brackish water region is under coastal aquaculture mainly for shrimp farming. Gradually shrimp production is increasing through horizontal expansion of the farming area, not by the desired vertical expansion. However, a limited area under shrimp culture has created some environmental problems, which may lead to ecological disasters, as well as socio-economic problems of greater magnitude if proper measures are not taken. Therefore, careful planning is necessary to develop an environment friendly integrated coastal aquaculture program as a sustainable technique. So that, coastal aquaculture would develop as a good source of animal protein for the growing population, a foreign currency earner and as well as maintainer of ecological balances in the brackish-water region. There is therefore an urgent need for sustainable development of the coastal resources, both for aquaculture/fisheries and agriculture. Remote sensing technique coupled with GIS are gainfully used or such a comprehensive analysis which lead to identification of suitable aquaculture site. So, it is necessary to conduct detailed surveys of the estuaries, brackish water, mangrove and mudflats for developing coastal aquaculture using remote sensing technique. By using remote sensing technique and GIS, the advantage is not only in time and cost effectiveness but also in achieving a more comprehensive and integrated treatment of aquaculture development criteria, which is difficult through conventional techniques alone.
