Abstract

Sampling had done from march 2012 until January 2013 from 7 locations. In this study a total of 75 species of seaweeds (macroalgea) were identified, from which 17 green algal species from 9 genera and 6 families; 18 brown algal species from 7 genera and 4 families; and red algal 40species from 18 genera and 11 families. From total times spent for sampling, it was determined that at Lengeh harbor with 6 species, had the lowest diversity of green algae. The species diversity of brown algae at Michael location with 10 species each; had the highest, and Tahooneh location with 5 species; had the lowest species diversity. Species diversity of red algae at Michael location with 28 species; had the highest, and Sayeh Khosh location with 13 species; had the lowest diversity. Coverage data of macroalgae and Ecological Evaluation Index indicate a high level of eutrophication for the Sayeh khosh, and Bostaneh, They are classified as zones with a bad and poor ecological status. It has been proved that concentrations of biogenic elements and phytoplankton blooming are higher in these zones. The best values of the estimated metrics at Tahooneh and Michael could be explained with the good ecological conditions in that zone and the absence of pollution sources close to that transect. The values of abundance of macroalgae and Ecological Evaluation Index indicate a moderate ecological conditions for the Koohin, Lengeh and Chirooieh.
