An analysis of fish diversity in a freshwater Bansagar pond of Rewa (M.P.) India

Abstract

This paper describes the analysis of fish diversity in a freshwater Bansagar pond of Rewa (M.P.) India, where fish diversity were conducted during Jan. 2020 to Dec. 2020. Human activities have resulted in drastic degradation of aquatic resources resulting in the alteration of structure and function. As fish constitute almost half of the total number of vertebrates it is very important that their diversity is preserved. Hence the present study was conducted to analyse the fish diversity in Bansagar pond. A total of 172 fishes belonging to 10 different families were identified. Among the various families, Cyprinidae recorded the highest species richness (6 species), followed by Channidae (3 species) and Bagridae (2 species). All the other families were represented by only one fish species. In terms of percentage, Cyprinidae represented 61.63% of the total fish population followed by Channidae 9.88%, Siluridae 6.98%, Bagridae 5.82%, Anguillidae 4.07%, Gobiidae 3.49%, Anabaenidae 2.91%; Aplocheilidae 2.33%, Cichlidae 1.74% and Clariidae 1.16%. Species richness 18, Abundance 172, Shannon Wieners Index 1.02, Simpson’s Dominance Index 0.092 and Simpson’s Diversity Index 0.91.
