This study describes about the spatio-temporal distributions in phytoplanktoncommunity such as species composition, standing crop and dominant species from May 2006 toFebruary 2007 in the Jangsu bay and the northwestern parts of Gamak bay. Based on theprincipal component analysis (PCA) of the environmental factors as well as biological parameters,the bio-oceanographical characteristics were analysed. A total of 83 species of phytoplanktonbelonging to 47 genera were identified. Whereas diatoms and dinoflagellates occupied more than65% and 30% of total species, respectively. The annual dominant species were Chaetocerosaffinis, Paralia sulcata and Bacillaria paxillifera in spring, Chaetoceros didymus, Ch. affinis andOctactis octonaria in summer, Skeletonema costatum-like species and B. paxillifera in autumn.
Moreover phytoplankton cell density was ranged between 3.1 cellsㆍmL- 1 in spring and 521.0cellsㆍmL- 1 in winter. It fluctuated with an annual mean of 76.0 cellsㆍmL- 1 between the lowestvalue of 7.6 cellsㆍmL- 1 in spring and the highest value of 220.2 cellsㆍmL- 1 by Skeletonemacostatum-like species in winter. Briefly, the phytoplankton cell density in the mixing seasons washigher in comparison with the other seasons. According to the PCA, the biological oceanographiccharacteristics of the Jangsu bay was affected by the introduction of outside seawater particularlyin temperature increasing seasons, and the other seasons, it may be described the light intensity,and mix between inner and outer bay sea waters.
