The present work focusses on the general ecological investigation on zooplankton population dynamics in terms of species composition and density in Kamalapaura water tank in Hospet city, newly born Vijayanagar district, Karnataka state. A total of 36 zooplankton taxa were identified and five classes namely Rotifera (14), Copepoda (6), Cladocera (7), Ostracoda (6) and Protozoa (4). The same trends were observed in terms of percentage with decreasing order Rotifera contributing 38.8%, followed by Cladocera (19.5%), Copepod, (16.8%), Ostrocoda (16.7%) and Protooa (11.2%). Maximum species richness was recorded 7.73 Margalef’s index (R1) at station D1 during pre-monsoon season and 1.16 Menhinick index (R2) at station K-3 during post-monsoon season, minimum Species richness was recorded 7.24 Margalef’s index (R1) at station K-2 during pre-monsoon season and 1.09 Menhinick index (R2) at station D3 during pre-monsoon season. Maximum species diversity was recorded 0.05 Simpson’s index (λ) at station D1 during the entire study, minimum species diversity was recorded 0.03 Simpson’s index ( λ) at station K-3 during the study period. Maximum of 2.86 Shannon - Weiner index (H’) at station D2 during post monsoon season and minimum of 2.42 Shannon - Weiner index (H’) at station D2 during pre-monsoon season. Maximum species evenness was recorded at stations K-1 and K-3 during post-monsoon season, minimum species evenness was recorded at station K-1 during pre-monsoon season. The study also indicates Kamalapura water tank is subjected to pollution due to addition of vehicular pollution and fertilizers from agricultural lands including domestic waste from the human habitation. This indicates the enrichment of water with nutrients leads to production of species, which in turn leads to the increased productivity and other undesirable biotic changes.
