Abstract: The present paper deals with the study of ichthyo-faunal diversity of glacier fed stream Balkhila. The stream Balkhila is an important tributary of Alaknanda River of Garhwal Himalaya. After its origin from the Lal Mati glacier, it drains through the famous Mandal valley of Garhwal region. The stream was represented by 10 fish species belonging to 3 families namely Cyprinidae (Schizothorax richardsonii, Schizothorax plagiostomus, Schizothoraichthys niger and Tor chelynoides), Cobitidae (Noemacheilus rupicola, N. montanus, N. denisonii and N. multifasciatus) and Sisoiridae (Pseudecheneis sulcatus and Glyptothorax pectinopterus). Among all these fishes Schizothorax richardsonii was abundant in the stream. The Schizothorax plagiostomus was common fish of the stream, whereas, rest all other fishes of the stream were found in less number. The relative abundance was calculated to show the abundance of different fish species of the stream. The various habitat preferences of different fish species were also studied. The diversity indices such as Shannon-Wiener diversity index, Simpson index, Margalef index and Sorensen’s similarity index was also calculated.
