Bicherli pond has been studied to evaluate the suitability of water for domestic use and maintaining for irrigation and other purposes. The investigations were carried out in Bicherli pond located at Ajmer District during February 1999 to January 2001. It was found that copepods were the dominant group at all sampling sites. Two peaks of zooplankton density were observed–one in May and other in November during 1999 to 2001. The mean maximum and minimum density were 3.84 No./L X103 and 2.26 No./ L X103 respectively. Temperature and Zooplankton density were at their peak in summer months. Maximum population of Protozoa was observed in September and minimum was in January ranging from 0.10 to 0.72 No. / L X103. Maximum population of Rotifers observed in July while minimum in September. Cladocera showed maximum density in May (1.15 No./ L X103) and minimum was recorded in September (0.41 No./ L X103). Copepoda showed two maxima, The first in May and the second in November and minimum was recorded in September ranged from 0.63to 1.72 No./L X103. Zooplankton studies in Bicherli pond, Beawar were undertaken to assess the health and status of the pond. The presence of pollution indicator zooplankton species like Brachionus, Moina, Daphnia, Cypris and Cyclops shows that the pond is under pollution. So strategies should be employed to reduce the increasing levels of anthropogenic activities and make water suitable for domestic use. Copyright@ International Science Community Association
