Fish population density, diversity and ecology of Maan reservoir Jirabad Dhar (M.P.) India

The Maanirrigation project was developed under the Narmada Valley Development project .Dam was constructed on the river Maan near village Jirabad district Dhar,it was drought prone area now about 1500 hectares of agriculture land covered under the command area of reservoir where 87% tribal farmer communities used water for domestic irrigation and fishculture Freshwater fish density and diversity was meagerly studied so that there was no proper documentation on fresh water fish resources of M.P. In the present studies 36species belonging to 21genera, 10 families and 4orders were recorded the family Cyprinidae was dominant group with the highest density and diversity while family Notopteridae and family Centropomidae had shown the lowest density and diversity during the course of study. The ecological parameters temperature, transparency TDS, pH, D.O. Alkalinity, BOD, hardness, chlorides were analyzed to determined the water quality status, the quality of water was under the limits of ICMR and WHO recommendations and suitable for fish culture and domestic purpose.
