Plankton doesn't care about borders they moving independently in the aquatic ecosystem. The phytoplanktons are a function of many of the some environmental processes that affect species diversity. Study of the physicochemical parameters is important for the effects on phytoplankton productivity. The coastal zone is also a dynamic area with many cyclic and random processes owing to a variety of resources and habitats. Studies of the abundance, distribution and composition of phytoplankton communities are, therefore, a fundamental contribution to our understanding of the structure and function of marine ecosystems. In many coastal systems, primary production is almost entirely a function of the phytoplankton. In the present study totally 46 species were recorded, the maximum species was recorded in Coscinodisceae (14) followed by Chaetoceraceae (8) > Biddulphoidae (6) > Naviculaceae (6) > Triceratiinae (4) > Solenoidae (4) > Fragilariaceae (2) > Euodicidae(1) > Eucambiinae (1) respectively. The maximum of species was recorded in Coscinodisceae and minimum was recorded species in different for sampling stations.
