Bio-diversity refers to variety and variability among genes, species and ecosystem on the earth. There are three levels of biodiversity namely genetic diversity, species diversity and ecosystem diversity. India is world’s eighth most bio diverse region with a 0.46 bio D score on diversity index. There were about 1, 02,718 species of fauna and 23.39% of nation’s geographical area under forest and tree cover in 2020. Today we are losing species continuously due to several causes such as climate change, human interference like hunting, trading, deforestation and environmental pollution. Threatened biodiversity needs to be conserved on the national, state, and local level by every citizen. In this paper an attempt has been made to analyze the responsible factors for decline in number of aquatic species and give some proposal for protection and conservation of the species in downstream part of Chambal sanctuary in Uttar Pradesh. The present study is based on area observation and secondary data. The National Chambal Sanctuary in UP covers an area of 635 sq. km., spread over the Agra and Etawah district. In the sanctuary along Etawah, Gharial population has been lost about 60% from year 1998 to 2006. In present time there are 200 Crocodiles, 1600 Gharials (Reptiles), 100 Gangetic Dolphin (Mammals) etc. in Uttar Pradesh. Several measures are being taken to protect aquatic species. These are legally managed by the central as well as state government and local citizens living around this area. Conservation is a positive work of management and maintenance of our heritage. It should be done for the sake of preserving our own culture and for sake of nature.
