The beaches, mangrove swamps, intertidal areas as well as upstream areas are used for coastal aquaculture. Careful selection of environmentally suitable sites is important for the success of aquaculture. This study aimed to analyze and identify suitable sites for aquaculture in Raigad District. More closeness of ponds causes spread of disease from one pond to other very rapidly. In the study area many aquaculture farms are very close to each other and lead disease spread; finally farming had to close. Hence, the success of a fish farming project largely depends on the site selection. Therefore, to identify suitable sites, with considering the local physical conditions by using this technique is useful for the development of aquaculture. In addition, the analysis can be used as an effective tool to diversify existing clustered farms into suitable areas for the successful shrimp farming.
