Zooplanktons are microscopic heterotropic organisms usually too small, present in aquatic environment. They are present at various depths in their own niches in every type of water bodies.The present investigation deals with the study of monthly changes of diversity and density of Zooplankton in Budki Dam of Shirpur in Maharashtra.
