| Reservoirs constitute the single largest inland fishery resource, both in terms of size and productive potential. The productivity of a reservoir depends on various factors such as the available water area, water quality, availability of planktonic food, stocking rate, methods of exploitation of the stock and the type of management of the fishery (Vass and Sugunan, 2009). A desirable level of productivity can be achieved in this man-made ecosystem only by a proper control of the above-mentioned factors on scientific lines. Geographical Information System (GIS) and Remote Sensing and mapping technologies can be used in selecting sites for culture and capture fisheries (Kapetsky, 1987). The maps can provide a long-term outline to the planners for aquaculture development (Kapetsky, 1989). |
