Abstract
The Godavari River is the second-longest river in India, and it flows through the states of Maharashtra, Telangana, Andhra Pradesh, and Odisha. The Northern Ghats are a mountain range that runs along the western side of the Godavari River. The region is home to a wide diversity of freshwater fish, with over 10 species recorded. This study investigated the freshwater fish diversity of the Godavari River in the Northern Ghats of India. In the Godavari River the Someshwar site were selected for the study, and fish were sampled using a variety of methods, including gill nets and cast nets etc. The fish were identified to species level, and their abundance was recorded. A total of 9 fish species were recorded in the study, belonging to 06 families. The most diverse family was Cyprinidae, with 04 species. Other important families included Bagridae, Gobidae, Ambassidae, Channidae and Mastacembelidae. The fish community structure was found to be heterogeneous, with different species assemblages occurring in different parts of the river. The most diverse sites were found in the upper reaches of the river, where there was less pollution and habitat destruction. The results of the study demonstrate that the Godavari River is home to a rich diversity of freshwater fish. However, this diversity is threatened by a number of factors, including pollution, overfishing, and habitat destruction. The conservation challenges facing the Godavari River are significant. However, there are a number of things that can be done to protect the riverâs fish diversity. These include reducing pollution, managing fishing practices, and protecting habitats.
