Phytoplankton was dominated by group of Bacillariophyceae (Diatoms) 61%. The other groups comprising of Dinophyceae 29%, Chlorophyceae (7%), and Cyanophyceae 3%. Phytoplankton abundance varied from 87-593 ind/L, the higest value in station 9 Zone III and the lowest value in station 11 zone III. Whereas the highest value of zone abundance was zone II 443 ind/L and the lowest was zone I 253 ind/L. Phytoplankton community was dominated by the group of diatoms, such as Nitzschia sigma, Thallasiothrix longissima, and Thallasiothrix delicatula.Keywords: Marine Phytoplankton, Bacillariophyceae, Marine of Riau1)
