PHYTOPLANKTONS AND ZOOPLANKTONS DIVERSITY IN KARACHI COASTAL SEAWATER UNDER HIGH AND LOW TIDE DURING WINTER MONSOON
Abstract
This paper represents the population density of phytoplanktons and zooplanktons recorded during the marine environmental studies at Karachi coast in the month of February 2011. Samples were collected by towing net, preserved and quantification and identification was carried out under light microscope. Twenty-three phytoplanktons species and nine zooplankton groups were recorded in the seawater from the sampling area of 10 square kilometers. Coscinodiscus and Copepods were dominant in the population of phytoplankton and zooplankton, respectively. Phytoplankton population density increased while zooplankton abundance decreased offshore from the coastline in the open sea.References
