Pre-impact Studies of the 2000 MW Lower Subansiri Dam on Certain Aquatic Environmental Aspects of Downstream of the River Subansiri with Special Reference to Plankton and Fishes

摘要

Pre-impact studies of the 2000 MW lower Subansiri dam have been carried out fromJanuary 2006 to December 2006 on certain hydrobiological aspects of downstream ofthe river Subansiri viz., physicochemical parameters, phytoplankton, zooplankton andfreshwater fish diversity. The water quality is suitable for planktonic and fish diversity.In the downstream of proposed dam, a total of 199 taxa have been recorded and identifiedwhich include 48 species of algae, 23 species of zooplankton, and 128 species offreshwater fishes belonging to 9 orders, 27 families and 78 genera.
