Effects of Aquaculture on Water Quality in Gudivada Region

In the Gudivada region, surface and ground water are important sources for drinking, agriculture, and aquaculture. The environment and human health gets depleted as the water and groundwater become contaminated as a result of man-made activities. The objective of this study is to provide a brief overview of the environmental impact of aquaculture as well as an assessment of ground water quality in the Gudivada Krishna District of Andhra Pradesh. Aquaculture activities have a substantial physical, chemical, and biological influence on water supplies. Physical pressure is exerted on the water; chemically, the water and land are polluted; and biologically, foreign species, infections, and diseases are introduced. For daily change activities, these aquaculture ponds require the mixing of bore-well or creek waters with fresh water; as a result of this practise, the upstream ponds discharging the polluted water into the channels, and the downstream ponds are utilising the same. This is attributed to increase of pollution in the aquatic environment. Over exploitation of water also leads to salt water intrusion, usage of ground water and conversion of land use to aquaculture. Pollution, damage of delicate coastal ecosystems, dangers to aquatic biodiversity, and significant socioeconomic costs are all factors to consider. Change in land distribution data over a period of 2005 to 2021 is collected and water quality parameters are collected and water quality index is assessed at three locations of gudivada region.
