Multi-criteria geospatial techniques for selecting potentially suitable sites for aquaculture development in Purba Medinipur, West Bengal, India

Published Online:pp 167-191

This study focuses on two analytical frameworks (a) site suitability for fish farming (SSFF) and (b) site suitability for commercial fish farming (SSCFF) of Purba Medinipur district. Physicochemical conditions, weather, environment, establishment and profitability were selected as suitability parameters. Spatial interpolation techniques were used to generalise the distribution of water quality, soil character, precipitation and population of the fisherman family. Proximity and spatial analysis techniques were used to assign the scale for perennial River, road-rail network, market, industries, sub-division capital and density measurement respectively. The distribution of land use and land cover (LULC) and slope has been characterised as another parameter. Weightage overlay analysis has been used to evaluate the distribution of suitable sites. SSFF model shows that 19.91% area is suitable, 67.71% moderately suitable and 12.38% areas come under the unsuitable category. The SSCFF model indicated that only 12.16 % area is suitable for the economically favourable fish firming.
