A survey was conducted on biodiversity of fish fauna and their conservation status of a freshwater river, Sarada in Visakhapatnam District of Andhra Pradesh, India with an objective to make a complete inventory of freshwater fishes and assess their conservation status. Regular bi-monthly sampling was conducted from January, 2011 to December, 2012 by using different nets with the help of artisanal fishermen. Fishes were also collected from local fish markets. We have collected 66 fish species belonging to 9 orders, 22 families and 38 genera. Order Cypriniformes was the dominant group with 26 species followed by Siluriformes and Mugiliformes each with 11 species, Perciformes with 7 species, Anguilliformes, Cyprinodontiformes and Mastacembeliformes each with 3 species and Osteoglossiformes and Elopiformes each with 1 species. Out of 66 species, 3 species are near threatened, 3 vulnerable, 4 at lower risk near threatened, 1 at lower risk least concern, 37 least concern, 15 not evaluated and for 3 species data is deficient as per IUCN (2013) Red List category. According to CAMP (1998) conservation status, 4 species are endangered, 13 vulnerable, 24 at lower risk near threatened, 2 at lower risk least concern, 22 not evaluated and for 1 species data is deficient.
