Zooplankton composition of 19 water bodies of Haveri district has been studied in post and pre monsoon season of 2004-2005.A total of 71 species were recorded, 38 of them belonging to rotifera, 22 cladocera, seven copepoda and four ostracoda.Of these, five species i.e. one cladoceran and four rotiferans were reported for the first time from this area.A maximum of 29 species were recorded from Akkialur tank, and only five species were recorded from Makaravalli tank.Frequently recorded rotiferans were Keratella tropica, Habrotrocha bidens, Brachionus calyciflorus, B. diversicornis, Keratella cochlearis, Lecane luna, L. leontina, Fillinia longiseta and F. opoliensis.Common Cladocerans were Diaphanosoma exicum, Ceriodaphnia cornuta, Moina micrura, M. macracopa.The regular copepods were Neodiaptomus strigilipes Heliodiaptomus viduus, Paracyclops fimbiatus, Tropocyclops prasinus and Mesocyclops leuckarti.Common ostracods were Hemicypris fossucula, Ilyocypris gibba and Darwinula sp.The species richness was high in pre-monsoon season compared to postmonsoon season.In Akkialur tank 15 species were found in postmonsoon season whereas 29 species were recorded in premonsoon season.Other tanks also showed the same trend.
