Bangladesh geographically comprised one of the largest delta landscapes of the world. Almost 6.7% of country’stotal area (147570 sqkm.) is covered byrivers and inland water bodies. These water bodies being rich in fishproduction meet the majority of the demand of protein. Bangladesh produces world's fourth largest quantity of fishand it is collected from the inland water bodies. Though shrimps were easily available in the inland water bodies forhundreds of years but shrimp culture as an export-oriented activity is a phenomenon of recent past. Bangladeshearned US$ 2.9 million by exporting shrimp in 1972-73 which was 1 % of the country's total exports. It increased to US$ 33 million in 1980 and to US$ 90.0 million in 1985. But until the mid-1980’s shrimp culture was principallydependent on open-water catches of shrimp it means that time shrimps were not cultivated in a proper planned way.But the culture of shrimp totally for export purpose started after the mid 1980’s. Since then the professional cultivation of shrimp had a very positive and effective impact on the economy of Bangladesh. Exports of shrimpfrom Bangladesh increased from US$ 91 million in FY (Fiscal Year) 1986 to US$ 280 million in FY1997. Duringthe corresponding period, the quantity of shrimp exports increased from 17.2 thousand tonnes to 25.2 thousandtonnes. As most of the shrimp farms have been developed without considering the sustainability of the environmentand some other factors like water pH & salinity, soil pH & salinity, soil texture etc. the farmers are getting lessreturn but affecting the environment most. Geographical Information System (GIS) can give an easier but effectivesolution here through selecting the best suitable sites for shrimp cultivation. Moreover GIS can solve thetransportation problem of this perishable product from the production area to the harbor or airport through transport route selection. This cansave a lot of money and time and consequently make the shrimp cultivation moreeconomic.
