Title Methodology to assess the biochemical oxygen utilization and production in estuarine ecosystems
 
Creator Selvaraj, G S D
 
Subject Marine Ecosystems
Seawater Analysis
 
Description 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.
