Fish diversity of river Narmada were studied during September 2006 to August 2007. After construction of Sardar Sarovar Dam on ri ver Narmada a major part of the running water is being converted in to stagnant water. The fish fauna were studied during construction of dam on the river Narmada. The fish diversity is correlated with biological and various physico - chemical parameters th at regulate the productivity and distribution of different species of the fishes. The fish population is abundant and majority of fishes are exploited for human consumption. In present study, attempts have been made to collect, classify and identify fish of river Narmada in its Western Zone. The study operated on a stretch of the river approximately 15 km from Piplud to Jangerwa from September 2006 to August 2007. The survey indicated that 51 species of fish were found in this zone of the river. The major fish abundance was noticed viz. major carps, minor carps and cat fishes. The several species of fish belonging order Clupiformes, Cypriniformes, Beloniformes, Opiocephaliformes, Mastacambelliformes, Siluriformes and Perciformes. In which maximum 37 species belonging to the order Cypriniformes. Some species of fishes like Cirrihinus cirrihosa, Aspidoparia jaya, Colisa fasciatus, Labeo bata, Oreichthys cosuatis, Osteobrama cotio etc. showed a declining trend in this stretch. The fish species diversity was dec reasing. Diversity Index was lowest 0.53 in March and was highest 1 in October in the year 2006 - 2007. The main reasons behind the decline of species are habitat destruction, introduction of exotic species, pollution and over fishing. An urgent need exist s for studying the life history traits and demography of the most important threatened fishes, as lack of information on these aspects have significantly affected conservation efforts.
