Ecology and distribution of zooplankton composition at Coringa Mangrove Area, East Godavari Deistic, Andhra Pradesh, India

This study was aimed to current diversity status of zooplankton of Coringa Mangrove river area East Godavari Deistic, Andhra Pradesh, India. The present study area 10 groups of zooplankton species was recorded in the Coringa Mangrove river area during the period of July 2013 to June 2014. The zooplankton percentage composition of each group in Coringa Mangrove river water was record in decreasing order Copepods 37%, Miscellaneous groups 21%, Coelenterates 11%, Mysidacea 9%,Decapods larva 9%, Chaetoghatha 7%, Rhizostomids 5%, Rotifer 4%, Ostracods 4% and Bivalve veligers 2%. The zooplankton composition was very high in the pre-monsoon and monsoon. The lowest zooplankton concentration was recorded during the post Mon soon and winter. The zooplankton percentage composition exhibited very high in mangrove water because of the high productivity due to mangrove litter fall that supports host of dexterous feeding of aquatic animals.
