ABSTRACT
Aquaculture activities are major impact on water resources both physical and chemical. Physically there is a lot of pressure on water; chemically it’s polluted the water as well as land degraded. It is due to poor planning of land and water resources management in the study area. On the other hand in the coastal areas farmers getting low income output from agricultural activities, liable flooded areas, and mud flats, open scrubs areas are largely converted in to Aquaculture ponds. These are good significance for the economic growth. Fresh water Aquaculture practices are more in the study area when compared to marine water aquaculture, majority of the Aquaculture ponds are situated near to the Kolleru Lake region. Those Aquaculture ponds are required large amount of fresh water for daily change activities, due this practices the polluted water discharged in to the channels from the upstream Aquaculture ponds that same water used by downstream Aquaculture ponds, this is the main cause for increasing pollution in many folds aquaculture environment. So GIS and Remote sensing techniques are very efficient to present situation and required to maintain the water resources, to control the pollution in the study area.
