Changes in diversity indices of freshwater snails Bellamya bengalensis and Lymanea acuminate from Malangaon reservoir in Dhule district were studied in three seasons of the year. It was observed that the diversity, density in the form of Shannon- Wiener index, Simpson’s index and Pielou’s index of both the species were highest in summer, lowest in monsoon and intermediate in winter. The population density of Bellamya bengalensis, was 10, 06 and 08 o/m2 in summer, monsoon and winter season respectively, while population density of snail species, Lymanea acuminata, in summer, monsoon and winter season was 04, 02 and 03 o/m2 respectively. The values of Shannon- Wiener diversity index at Malangaon reservoir were 0.5983, 0.5624 and 0.5860 during summer, monsoon and winter season respectively. The values of Simpson’s index of diversity at Malangaon reservoir were 0.4396, 0.4286 and 0.4364 during summer, monsoon and winter season respectively. The species richness at Malangaon reservoir was 02. The values of Pielou’s index of evenness at Malangaon reservoir were 0.8631, 0.8114 and 0.8454 during summer, monsoon and winter season respectively.
