Abstract
The Mahanadi River is one of the major rivers in the country. This
study was split into seven regions of the Mahanadi river for sampling to
evaluate fish diversity. The sampling areas were situated in riverine areas,
from upstream in Sambalpur district to downstream in Jagatsinghpur district of
Odisha. The choice of sites was determined by areas where fishing communities
live. and take part in fishing activities. Standard protocols and techniques
were adhered to throughout the sampling, data gathering, and analysis
processes. A total of 42 fish species were recorded, representing 37 genera, 18
families, and 7 orders across seven sites along the Mahanadi River. The
assessment disclosed that the family Cyprinidae was the most dominant, come up
with 34% of the total species recorded. The distribution pattern indicated
greater diversity of species at water dams, barrages, or storage facilities.
Several species, including Catla catla, Labeo rohita, Cirrhinus mrigala,
Labeo bata, Clarias batracus, and Chanda nama. found to be in good
abundance in the study regions. The conservation assessment indicated that at
least 24% of the fish fauna is under threat, being classified as either
vulnerable or near Threatened. These findings highlight the urgent need to
embrace effective biodiversity conservation measures to safeguard the fish
diversity of the Mahanadi River and preserve this vital natural heritage.
