عنوان مقاله [English]
In this research 47 genus of different phylum of phytoplanktons such as Cyanophyta, Chlorophyta, Pyrophyta, Chrysophyta and Euglenaphyta were surveyed that their numbers (ind./m^3) and biomasses (mgr/m^3) were estimated. Frequncy of phytoplantons (ind./m^3) was 131.2, 1.6, 65.3, 18.9 and 23.8 million respectively. Furthermore, their biomasses was 08.4, 1.9, 1358.9, 295.1 and 124.7 mgr/m^3, respectively. The maximum and minimum numbers were observed in Leptolingbaya belonged to Cyanophyta and diatoms of Chrysophyta 84.3 and
0.025 million ind./m^3 respectively. The maximum and minimum biomass was observed
in Gyrosigma (Chrysophyta) and Tetradron (Chlorophyta), 12317.3 and 0.014 mg/m^3 respectively.
