Abstract : The present study on fish faunal diversity of River Siang of Arunachal Pradesh was carried out from 2012 to 2013 in different seasons throughout the year. The present Studies on River Siang reveals the presence of different 90 species of fishes belonging to 8 orders, 24 families and 59 genera. Cypriniformes dominates the whole river; Beloniformes and Tetradontiformes are found in less numbers. The water sample is collected from the Six (6) different parts of the river on the basis of microhabitat and analyzed different types of water parameters. The results of Physico-Chemical Parameters that are recorded in the different stations are compared with the World Health Organization (WHO) and it was found that the water of River Siang may be suitable for drinking and domestic purposes because all the values are between WHO. This study illustrates the potential application of GIS and Remote Sensing techniques to support the river analysis and its management. Remote Sensing and GIS are familiar as an influential tool to attain this purpose in aid of a well-versed management decision system.
