Abstract: In the present study, the ichthyofauna diversity was recorded and its relation was studied seasonally to physico-chemical parameters of River Chopan (Gopi Krishna Sagar Dam), district Guna,Madhya Pradesh has been studied. Three stations were selected for study, S I-Paanj (Centre line of dam), S II Dahaye (2 Km from SI) and S III Bajrangarh (5 Km from S I). Fishes were collected by the help of local fishermen. These were identified and their local names were noted. Scientific identification was done in laboratory and fishes were classified accordingly. Physico-chemical parameters as temperature (ºC), pH, Turbidity, dissolved oxygen (DO2), Alkalinity, Hardness, Free CO2,Biochemical oxygen demand , Chemical oxygen demand, Total dissolved salts and Chlorinity were tested. Effect of these parameters with fish diversity was related. In the present study till now 23 species of fishes have been recorded which belongs to nine families and six orders of which maximum fishes belonged to family Cyprinidae. Protection of biodiversity has become an important concern .Due to increased intervention of man on various freshwater aquatic bodies have brought extinction of a number of fish species
