Abstract: 

CYANOBACTERIA ARE CLASSIFIED AS BACTERIA (LACKING A MEMBRANE-BOUNDED NUCLEUS) THEY ARE PHOTOSYNTHETIC AND ARE INCLUDED AMONG OUR ALGAL COLLECTIONS. CYANOBACTERIA PLAYED A DECISIVE ROLE IN ELEVATING THE LEVEL OF FREE OXYGEN IN THE ATMOSPHERE OF THE EARLY EARTH. CYANOBACTERIA CAN CHANGE REMARKABLY IN APPEARANCE, DEPENDING ON THE ENVIRONMENTAL CONDITIONS AND SOME THE CURRENT STUDY IS CONTINUES OF PREVIOUS STUDY IN CASPIAN SEA THAT TOOK PLACE ON THE FEEDING OF MNEMIOPSIS AND CHANGE ON CYANOBACTERIA. THE SAMPLES WERE TAKEN FROM 6 LINES LISAR, ANZALI, SEFIDROOD, NOOSHAHR, BABOLSAR, AMIRABAD THAT EVERY LINE HAVE 4 STATIONS(A, B, C, D)AND WATER FOR ANALYSIS HAVE TAKEN FROM DIFFERENT DEPTH(0, 10, 20, 50, 100) METERS IN SOUTHERN OF CASPIAN SEA, THAT, TRANSFERRED TO THE CASPIAN SEA ECOLOGICAL INSTITUTE LABORATORY. IN SOUTHERN CASPIAN SEA ALONE RECORDED 45 SPECIES OF CYANOPHYTA, ACCORDING TO THIS STUDY. IN COMPARISON AFTER MNEMIOPSIS ARRIVAL, PHYLUM OF CYANOBACTERIOA INCREASED SHARPLY IN TERMS OF SPECIES PERCENTAGE AT THE SAME TIME BY MNEMIOPSIS ARRIVAL THE DOMINANT SPECIES OF CYANOBACTER IN SOUTHERN CASPIAN SEA WERE ANABAENA SPIROIDES, ANABAENATENUIS, OSCILATORIA LIMOSA, OSCILATORIA GEMINATA, APHANOTHECE ELABENS, MICROCYSTIS AERUGINOSA, MICROCYSTIS SP, MERISMOPEDIA PUNCTATA, ANABAENOPSIS CUNNINGTONII. IN CASPIAN SEA WATERS, BECAUSE OF DIFFERENT PHYSICOCHEMICAL FACTORS AS DIFFERENT SEASONS, RIVERS, CIRCULATION, POLLUTION AND BIOLOGICAL FACTORS SPECIAL MNEMIOPSIS LEIDYI OBSERVED CHANGING IN DIVERSITY CYANOBACTERIA IN DIFFERENT TIMES AND AREAS SPECIALLY IN SOUTHERN OF CASPIAN SEA.
