Geographic Information System (GIS) is a very important tool that helps in the spatial planning of an activity. GIS Combines the utilities of storage, management and analysis of both spatial and non-spatial data for effective decision making. GIS incorporates data sources like Remotely SENSED imagery, existing maps, attribute point data and facilitates the analysis involving all these data sources as layers to take informed spatial decisions. GIS has been used in several instances in aquaculture and its related activities. GIS for aquaculture site selection has been explored and is now being used as a regular tool in the reconnaissance and identification of suitable areas for aquaculture. Remote sensing systems have not been designed specifically to support fisheries and aquaculture management, but users take advantage of sensor capabilities mainly developed for broad applications in land surface mapping, weather forecasting and oceanography. The main applications of remote sensing for fisheries and aquaculture are in support of aquaculture development, aquaculture practice and management (including impact assessment), and for various aspects of marine fisheries monitoring and management. A small number of studies have looked at remote sensing applications to inland fisheries.
