Pollution and Zooplankton Diversity in Koyali and Dumad Pond of Vadodara, Gujarat, India

In present study, the Dumad pond was considered as non-polluted site and the Koyali pond as the polluted site, being in the middle of the industrial area. A comparison of the zooplanktonic community structure, population density and species richness clearly describe the deteriorating status of Koyali pond. Unfortunately, the pond is routinely used for fish culture practice, posing threat to the consumers and to the ecosystem as a whole. The zooplankton diversity of koyali and dumad pond can be chiefly represented by phyla Rotifer and Arthropoda. The rotifer community composed of one class, one order, 6 families and 20 genera/species. Family Branchionidae dominated with maximum of 14 genera. Family Filidinae and Lacinidae were represented by 2 genera while other 3 included one genus each (Table 1). Arthropods were classified into three classes, 4 orders, 11 families and 24 genera/ species.
