Diversity of the Ichthyofauna at the Ghunghutta Dam in the Surguja District of Chhattisgarh.

Abstract

The study discusses the richness of the ichthyofauna at Ghunghutta Dam in Surguja District, Chhattisgarh, where research on fish diversity was done from December 2020 to November 2021. Aquatic resources have suffered severe degradation as a result of human activities, altering both structure and function. It is crucial to maintain the diversity of fish because they make up about half of all vertebrates. In order to analyze the fish diversity in Gunghutta Dam Ambikapur, the current study was carried out. There were found to be 82 fish altogether, divided into 8 different groups. Cyprinidae had the highest species richness (6 species) among the different families, followed by Channidae (3 species) and Bagridae (2 species). Only one fish species was present for each of the other families. Cyprinidae made up 61.63% of all fish species, 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%) in percentage terms. 16 species, 82 individuals, 1.02 Shannon Wieners index, 0.092 Simpson's dominance index, and 0.91 Simpson's diversity index.
