Fish Diversity, East Siang, Lohit River, Arunachal Pradesh, Brahmaputra, Garra.


The present work is a result of a Preliminary survey on the fish diversity of two major rivers of Arunachal Pradesh i.e Siang river and Lohit river at Pasighat and Tezu. A total of 24 species belonging to 5 families of Cyprinidae, Siluridae, Sisoridae, Belonidae and Bagridae were collected. Among them, Barilius, Garra, Tariqilabeo, Glyptothorax were commonly found in both the rivers. While in Lohit River of Tezu a greater number of species of the genera Raiamas, Xenentodon, Pterocryptis, Pseudocheneis, Schizothorax, Batasio, Puntius, Wallago were collected. A new species of garra is also reported belonging to “Smooth snout group”, having prominent, regular scales on abdomen, moderately large gular disc, broader than long (length 37.4% HL,55.3 width % HL), anus posteriorly positioned, a black spot at upper angle of gill opening.
