Abstract

The procedures presently followed for the determination of BOD and COD of coastal waters are complicated, time consuming, and expensive leading to practical difficulties in the field laboratories of aquaculture farms and research organisations, without serving the purpose at times of emergency. The objective of the present study is therefore to understand as quickly as possible whether the water by nature provides an oxidizing or reducing environment and to know the net rate of biochemical oxygen consumption / production per hr or day, based on a simple light and dark bottle technique of oxygen estimation by Winkler's method with an incubation of 2-3 hrs, assuming that light bottle gives the net production~consumption value of oxygen for the day time and dark bottle for the night time.
