Marine Fishery Information System and Aquaculture Site Selection Using Remote Sensing and GIS

Abstract

In this project, the Marine Fishery Information System has been suggested with the help of Remote Sensing and GIS. The information system provides the suitable site for Aquaculture including offshore and onshore of the Tuticorin Coastal area in Tamilnadu, India and Marine Fish Resources system provides location details about fish resources such as Prawn grounds, Pearl Oyster beds, Small Fishes and Chunk beds in Gulf of Mannar, India. The site suitability analysis for Aquaculture delineate with the help of Multi Criteria Evaluation (MCE) technique. Satellite Remote Sensing (RS) and Geographic Information System (GIS) have a decisive role in providing regular, synoptic, multi-spectral coverage of an area. With the launching of the Indian Remote Sensing Satellites (IRS) a wide range of Remote Sensing data at different spatial and spectral resolutions are now available for the monitoring and management of natural resources. GIS technique help in the integration of databases covering a variety of relevant parameters in an efficient manner. At the present moment, the following parameters are considered in site selection conflicting uses of area, settlements, waste lands, salt pan, pollution, depth profile, distance from the sea, distance from the land, coastal topography, and water bodies, soil, geology and geomorphology. The main goal of this research is to delineate the suitable area for Aquaculture and Marine Fish Resources mapping through the various Image Processing Technique, Field Survey and GIS analysis, using IRS P6 LISS 3, LANDSAT ETM, MODIS Level 2 satellite image, Bathymetry Sounding Point, Electronic Navigational Chart and various parameters data bases.
