This study examines the diversity of fish fauna in two freshwater bodies (Minimata dam and Khudia dam) of Chhattisgarh. Two freshwater bodies viz; Minimata dam and Khudia dam of Chhattisgarh were sampled for assessment of fish faunal diversity. Sampled freshwater bodies of Chhattisgarh were surveyed and the fish species were caught in nets by using boats. Different diversity indices were evaluated to examine the difference in the diversity, richness, evenness and relative abundance of fishes found in the sampled freshwater bodies of Chhattisgarh. The results reveal that a total of 49 fish species belonging to 09 orders, 18 families, and 34 genera were reported from Minimata dam and Khudia dam of Chhattisgarh. Cyprinidae (42.85%), Bagridae & Clariidae (8.16%), Siluridae (6.122%), Schilbeidae, and Centropomidae & Anabantidae (4.08%) were the most dominated families. Labeo rohita was the most abundant (6.182%) freshwater fish species in the sampled freshwater bodies of Chhattisgarh.The average species richness of Minimata dam was 49.00±2.64 and Khudia dam was 43.0±3.51. The Simpsons index(D) reported a similar trend with highest values recorded by Minimata dam and lowest values recorded by Khudiya dam. The Shannon’s diversity index (H) recorded highest average values in Minimata dam (2.90±0.09) lowest in Khudia dam (2.36±0.08) respectively. Despite the low fish diversity in the sampled freshwater bodies of Chhattisgarh, the Shannon’s index (H) varies from 2.36±0.08 to 2.90±0.09. The results of the present study confirm that the Minimata dam of Chhattisgarh have higher diversity, richness, evenness and relative abundance of fishes than Khudiya dam. These results can be utilized for the management of fish resources and of the sampled freshwater bodies of Chhattisgarh.
