    ZOOPLANKTON DIVERSITY AND SEASONAL VARIATION OF THREE LAKES IN COIMBATORE, TAMIL NADU, INDIA
    (Journal of Academia and Industrial Research, 2016-08) R, Manikandan; S, Selvakumar; S, Kalaichelvi; N, Ezhili
    The present study was carried out to examine the diversity and density of zooplankton in Ukkadam Lake, Kuruchi Lake and Singanallur Lake in Coimbatore city, Tamil Nadu for the period of September 2012 to August 2013. The samples for Zooplankton analysis were collected early in the morning by plankton net of silk bolting cloth size of 25 µ and preserved in 4% formalin and glycerine for zooplankton analysis. During the present study period, a total 30 of genera of zooplankton composed of 8 genera of protozoa, 9 genera of Rotifer, in which 7 genera belonged to Cladocera and 6 to Copepoda were recorded in all the three lakes. Dominance of Rotifers indicated the eutrophic status of these studied lakes. Species diversity index for zooplankton population varied from 1.74 to 3.63. The zooplanktonic fauna of this lake were abundant during summer season while minimum numbers were recorded during rainy season. The present study findings clearly indicate intensified eutrophication of studied lakes.

    DIVERSITY AND SEASONAL VARIATION OF ZOOPLANKTON IN UKKADAM LAKE, COIMBATORE, TAMIL NADU, INDIA
    (International Journal of Current Research, 2013-08) N, Ezhili; R, Manikandan; R, Illangovan
    Zooplanktons are good indicators for changes of water quality, because they are strongly affected by environmental conditions and respond quickly for the changes in environmental quality. The present study was carried out to examine the diversity and density of zooplankton in Ukkadam lake, Coimbatore, Tamil Nadu, India, for the period of one year from May 2003 to April 2004. During the present study period, a total of 36 genera of zooplank 6 to Copepoda maximum during summer (March, April and M for zooplankton population varied from 1.74 to 3.63. Maximum numbers of zooplankton were recorded in the months of March and October. result was clearly indicating intensified eutrophication of lake
