Abstract
Geomorphologically, Sundarban is the active portion of the Gangetic delta in which the processes of land formation and erosion, ebb wave activeness are pronounced. The important productive and profit oriented sector in Sundarban after agriculture is aquaculture. The main aim of the study is to assess the suitable site selection of fishing zones for Kakdwip sub-division mainly consisting of Kakdwip, Sagar Island, Patharpratima and Namkhana blocks. The Land Use & land Cover Map (LULC) shows an increasing Tend of settlement and increasing nature of aquaculture pond in this region. The study of the fishing zones can be done with the use of a technology based Site Suitability Mapping of Kakdwip sub-division with the help of Weighted Overlay Analysis. The site suitability mappings have been done on the basis of the weightages given to Land Use & Land Cover (40%), Euclidean Distance (40%) and Slope (20%). The Euclidean Distance is prepared on the basis of suitable fishing zones near the settlements with the point data extraction. The LULC, Euclidean Distance & Slope have been reclassified for the final preparation of the Site suitability mapping for identification of different zones. The Arc GIS 10.1 software helped in marking the suitable sites for fishing zones. Finally the zones are divided into eight classes where the suitable sites are observed along the shoreline part of the area and the marine zone along the creeks, whereas some parts of inner core land is not suitable for fishing that has been depicted in the present study.
