Biodiversity indicates the potential of any aquatic system and also depicts its trophic status. It is important to have an adequate knowledge of the constituent biota especially for the purpose of conservation and management of the inland water resources such as rivers, reservoirs and ponds. Ichthyofaunal studies were undertaken during July-2009 to June-2010 in Pakhanjoor reservoir Kanker district, Chhattisgarh, India. The aim of the paper was to assess the variety and abundance of the important fish fauna inhabiting this region. 42 fish fauna identified during the study belongs to Cyprinidae 23 species, Bagridae 04, Cobitidae and Ophiocephalidae 03, Siluridae and Centoopomidae 02, and a species each of Saccobranchidae, Claridae, Mugilidae, Nandidae and Gobidae. The species diversity is peak in post monsoon and was low in premonsoon. To save this diversity and to develop a sustainable fishery practices and proper documentation, leading to diversity information system is an urgent need. The paper describes the detailed species composition their relative contribution and also some important points that may help to better understand the current scenario of ichthyofaunal diversity.
