The effect of physical and chemical factors on the species diversity, distribution and density of blue-green algae was examined along the Nour shore of the Caspian Sea. Sampling was seasonal conducted during four sampling campaigns along four transects (A, B, C, D) each bearing three sampling sites (from 1 to 3) in February May, July and November 2014. As a result, 13 species of Cyanophyta division belonging to nine genera, were identified. The highest cyanophyte cell density was observed in summer, when 38 × 105 cells l-1 was noted. However, the results of variance analysis illustrated that there is no significant difference between Shannon’s diversity index in different season (P
