Studies on certain aspects of eutrophication of fresh water ponds at Barrackpore

In the present study, non-conservative abiotic parameters and biological conditions were utilized to portray the causes, consequences and magnitude of anthropogenic eutrophication in 4 fresh water perennial community ponds at Gangetic West Bengal, India. In order to classify the ponds, a single criterion basis was adopted and more emphasis given to the species of plankton which are biological indicators of eutrophication. Besides this, various abiotic parameters were also studied. On the basis of results obtained, 4 ponds have been classified as "Eutrophic, Tropical Bacillariae".
