Abstract: 
In this research, the density of diatoms has estimated in coastal waters of Persian Gulf, in Tiab Creek to Bandar Lengeh in October 2003 to September 2004. There were five transects, include Tiab Creek, Fishing Jetty of Bandar Abbas, Nafti Jetty of Bandar Abbas, Bandar Khamir and Bandar Lengeh. Sampling was performed with a Ruttner sampler at three different depths (surface, 2 and 5 m) in three stations in each transects. In this review, 40 genera of diatoms were identified and Nitzchia, Thallassionema and Pleurosigma were identified as the dominant genera. The highest and the lowest diversity of diatoms were in autumn and spring with 39 and 28 genera, respectively. Mean density was 2004 cell per liter and peak of diatoms was in summer (4080 cell per liter) and the minimum was in spring (1914 cell per liter). Maximum of diatoms was observed in Fishing Jetty of Bandar Abbas and Khamir Port, respectively. Diatom’s density was higher in 5 m in compared to 2m and surface waters but there was not significant difference (P>0.05). Results of One – way Analysis of Variance (ANOVA) and LSD test, showed that there were no significant difference (P › 0.05) in density of diatoms in seasons, but there was a significant difference (P ‹ 0/05) in different transects.
