Maheshwari, Ramesh (2005) Fish death in lakes. In: Current Science, 88 (11). pp. 1719-1721.
An incidence of mass-scale fish mortality in Bangalore was reported recently in the local newspaper as front-page headline1:'Five tonnes of fish die in Ulsoor Lake. From being a clear, tranquil water body, the recently restored Ulsoor Lake has become a sea of dead fish'. Among the views expressed as the cause of this tragedy were 1-3: (i) Chemicals flushed into the lake, following a cleaning of the BCCowned Ulsoor swimming pool; (ii) lowered Biological Oxygen Demand; (BOD) level due to the approaching summer [BOD, expressed as mg O2 per l, is the amount of dissolved oxygen needed to oxidize organic materials to carbon dioxide and water at a particular temperature and pressure. If there is a large quantity of organic waste, there will be a lot of bacteria working to decompose this waste.
