Abstract: The current study intends to provide an overview of fish diversity of river Narmada at Jabalpur region. The fish diversity is correlated with biological and various physic-chemical parameters that regulate the productivity and distribution of different species of fishes. The fish population is abundant and majority of fishes are exploited for human consumption. In current studies, attempts have been made to collect, classify and identify fish of river Narmada in Lamhetaghat and Bhedaghat sites. The survey indicated that 29 species of fishes were recorded in these sampling stations. The major fish abundance was noticed viz. major carps, minor carps and cat fishes. The several species of fish belonging to order Cypriniformes, Beloniformes, Ophiocephaliformes, Perciformes and Siluriformes are recorded too. Out of these Cypriniformes is the most dominant group with recorded 22 species of fishes. Some species of fishes like Cirrhinus cirrihosa, Labeo bata showed a declining trend in the stretch. Diversity was observed to be lowest in March (2011) and was highest in November (2010). The main reason behind the declining species diversity is introduction of exotic species, habitat destruction and over-fishing. A nearly Gelatin factor i.e, (Erstwhile shaw Wallace Gelatins Ltd) also add up to the contribution to an extent.
