Rohitee ogilbii (Sykes, 1839) is the endemic species of Western Ghats of Maharashtra the fish belongs to the family Cyprinidae and order Cypriniformes. The study is undertaken so as to understand the population dynamics of the population. Population dynamics plays an important role in understanding the status of the fish in natural habitat. The sex ratio is defined as the comparison of number of male individual to female individual of a given species in a natural habitat. An statistical study of the sex ratio in Rohtee ogilbii (Sykes, 1839)in various seasons is an essential parameter for obtaining information on seasonal segregation of the sexes and their abundance in spawning season of the fish. The results clearly show the ratio of female: male is highest during the month of June 2.14: 0.466. The ratio of female: male was lowest in the month of January 1.08:0.923. According to the data obtained month wise ratio was calculated by using chi-square (x2). The chi-square value obtained in the present study showed 3.84 which are significant at 5% level. There were slight deviation in the ratio for few months in the present study but it could be attributed to the environmental stress on the habitat.
