Abstract

The state of Arunachal Pradesh, in the extreme north east of India is located within one of the global  biodiversity hotspots of the world-the Eastern  Himalayas. The state is blessed with variety of aquatic  resources in the forms of streams, falls, rivers and  lakes. Amongst the various freshwater lakes within  the state, Ganga Lake (GyakarSinyik) is the only lake,  a major wetland in the Papum Pare district and in the  Itanagar Wildlife Sanctuary as well. An attempt has  been made here to prepare a brief account on the  zooplanktons found in the only natural lake near the  capital city of Itanagar.The lake is at threat from  geological point of view because of its location on the  top of a hill and weakened banks on the western side  and anthropogenic activities. An assessment of the  physicochemical characteristics and zooplankton  diversity study was done in order to understand and  document the present status of the lake. Foldscope is  used to identify the various species of zooplanktons  found in the lake. The foldscope is aultra-low-cost  origami-based portable microscope, and it was used  effectively to identify the various zooplankton species.  A total of 16 genuses of zooplanktons comprising of  16 species belonging to 3 genera of protozoa, 6 genera  of rotifera, 3 genera of cladocera and 4 genera of  copepoda were observed during the present study.  Physicochemical studies showed that the pH,  temperature, DO and other parameters were  favourable for biotic sustainability. The conductivity,  transparency and turbidity levels observed during the  study indicate that the quality of water is fit for  aquatic life. The present study provided valuable  information on water quality and distribution of  various zooplankton communities of the lake.
