Distribution and Diversity of Freshwater Fishes in Aami River, Gorakhpur, India

The fish diversity of the Aami River in relation to physicochemical parameters was studied by monthly samples taken from January 2011 to August 2012. The water of the River is used for industry, fishery and local area people. Cast net were used for fish sampling, which was done from 9:00 AM to 5:00 PM. The results of present investigation reveal the occurrence of 18 fish species belonging to 6 order, 11 family and 17genera. Among the collected species, order Cypriniformes was the most abundant in all sites besides this order Beloniformes, Mastacembelida, Symbranchiformes, Perciformes, Centropomidae, Amphipnoidae, Ophiocephalaidae, Clupeidae, Sisoridae, Clariidae, Bagridae, Saccobrachidae also were present but its number is very less in all sites. Over fishing, industrial, chemical, agricultural runoff and other form of pollution are the most important which should be restricted for the conservation of freshwater fish diversity. Therefore, it may be concluded that preparation of zone wise database of these information and their implementation through government and non-government organization would be the key tools for conservation of freshwater fish biodiversity.
