  Abstract

 Hypoxia is a frequently occurring environmental phenomenon in the freshwater and even coastal system of a tropical country like India. It may be naturally occurring phenomenon due to biological and physical factors or may be caused due to anthropogenic activities around the water bodies. In tropical aquatic system such as India, dissolved oxygen in the water of pools, swamps, lakes and rivers may change radically, from almost 100% saturation or sometimes hyper saturation at noon to zero at night of the same day. Sharp seasonal fluctuations also occur frequently occurring. Low oxygen concentration occurs in a wide range of aquatic systems and range in temporal frequency, seasonality and persistence. These have always been naturally occurring low oxygen habitat but anthropogenic activities related primarily to organic and nutrient enrichment have led to increase in hypoxia and anoxia both in fresh as well as marine system. Freshwater systems are more frequently faced with low oxygen condition and fishes in a tropical country like India are quite frequently exposed to this. The general public is aware of the results of hypoxia as the phenomenon of “Fish Kills” occurring frequently in natural waters
