| Abstract | ||
| This study was carried out in 27 study stations in Shijan, Siahkishim, Abkenar, Hendekhaleh and Rogaha(River outlets), during conducting research hydrology and hydrobiology and preparing Atlas of plankton in the Anzali wetland during the years 1994 from 2014. Sampling was done by (P.V.C) tube, For phytoplankton (1 liter of water sampels) were Collected and fixed with 4% formalin and then transferred to the laboratory and after quantitative and qualitative studies with inverted microscope were taken picture them by Nikon photo microscop. In total, 19 genus and 32 species were identified in the Cyanophyta. This phylum includes a category known as Myxophyceae, commonly called the "Blue Green Algae", The most abundant species of Cyanophyta are Oscillatoria sp. ,Merismopedia convoluta ,Microcystis aeruginosa and Anabaena spiroides. All members of this category have maximum frequency in the summer and early autumn seasons (October), and their most frequent distribution is in the Abkenar area. In general, the purpose of this research was to determine the role and importance of the environmental management of this group in Anzali wetland ecosystem. also, by studying the population, biomass and distrbution of plankton in different areas of this wetland, the production and fertility potential were evaluated and its environmental effects in fish life have been met to restore the natural reproduction sites of migratory fish and feeding their larvae. | ||
