Title

THE RELATION BETWEEN ENVIRONMENTAL PARAMETERS OF HORMUZGAN COASTLINE IN PERSIAN GULF AND OCCURRENCE OF THE FIRST HARMFUL ALGAL BLOOM OF COCHLODINIUM POLYKRIKOIDES (GYMNODINIACEAE)

Pages

  475-489

Abstract

 Cochlodinium polykrikoides was bloomed in the PERSIAN GULF for the first time in September 2008, started from the Strait of Hormuz and then spread out towards the northern parts covering most of the areas of the Gulf and lasted 8 months. In order to find out ENVIRONMENTAL CONDITIONS during the bloom, a monthly sampling program was carried out in seven surface stations in 2008-2009. At each station, three samples (triplicates) were collected for phytoplankton analysis and also one sample for environmental analyses, including salinity, chlorophyll a and NUTRIENTS. Blooms of C. polykrikoides were observed with a seawater temperature of 20.1 to 31.0°C, salinity 37.0-40.1 ppt and nutrient concentration ranges during the bloom and RED TIDE were 0.064-0.707 mg/l nitrate+nitrite and 0.001-1.66 mg/l phosphate, respectively. Maximum of C. polykrikoides abundance was measured 26´106 cells L-1 in October 2008. Kruscal wallis test demonstrated a significant difference in densities and chlorophyll-a in different months and seasons not in different stations. This study showed increase of temperature (>31.0°C) stopped bloom and RED TIDE due to C. polykrikoides in both the eastern and middle sampling stations but in the western stations was determined decrease in nutrient amounts as the major factor therefore increased nutrient of coastal waters, and ENVIRONMENTAL CONDITIONS could have efficacy the occurrence of this din oflagellate.
