The relationship between diversity or density of phytoplankton and other marine fisheries sector is of great importance. The study of Spatial and temporal variability of distribution of phytoplankton communities in the coastal waters of the Northern Persian Gulf (QESHM, LENGEH) were studied during 2008. In this study, five groups (47 genera) of phytoplankton include, Bacillariophyceae, Dinophyceae, Cyanophyceae, Crysophyceae and Euglenophyceae were identified. The result showed that Diatoms group (79.6 %) and Rhizosolenia genus (45. 5 %), contributed more towards the percentage composition of different groups and genera of phytoplankton at the during Study. The annual changes in relative abundance and Margalef, Shannon, pielu and Simpson indices were estimated, 0.58-2.56, 0.08-0.97, 0.23-2.6, 0.09-0.93 respectively. Multivariate analysis of variance showed that during the study, density and biological indicators of phytoplankton were significant between seasons (p<0.05). The spatial cluster analysis based on similarity coefficients obtained two clusters in the areas studied. According to the results obtained can be concluded that both the area of ecological conditions in ranks are instead moderate. Also, phytoplankton of diversity and richness is good.
