Zooplankton Diversity and Physicochemical Profile of Ameenpur Tank, Telangana, India

Abstract

Zooplankton composition and diversity in Ameenpur tank, Telangana, India were investigated during the year 2010-2012. The study reveals the occurrence of 55 species of zooplankton, of which 38 species rotifers, 14 cladocerans and 03 copepods. The population density varied from 195 to 5500Ind./L. The highest density of zooplankton was due to rotifer population. Diversity (H´) ranged from 0.6 to 2.45, evenness (J´) was 0.21 to 0.80 and species richness was 5 to 27. The population abundance because of Brachionus angularis, B. calyciflorus, B. caudatus, B. falcatus and B. rubens, Keratella tropica, Ceriodaphnia cornuta, Moina micrura, Bosmina longirostris, Indialona ganapati and Mesocyclops leuckarti. The significant inter and intra relationship between and within physicochemical and zooplankton indices were noted. Zooplankton diversity and physicochemical parameter reveal the change in the trophic status of Ameenpur tank.
