Abstract:
A study was performed to determine the amount and activity of living algae in fresh water by measuring the dehydrogenase activity (DHA) of algae in order to provide a method to assess the effect of algicide treatment. The conditions of measurement were researched with respect to incubating temperature and duration, and selection of extractants. The comparison between this method and an alternative method, chlorophyll a, shows that this method is simple and easy to practice, and can determine the effect of algicide treatment.
