An investigation on identification and primary production of brown algae and effect of ecological factors on the vegetation in seashores of Bandar Lengeh

Bandar Lengeh is one of the important areas of algal distribution in coast of Hormozgan province (Persian Gulf). The investigation carried out along coastal lines of this area from sept. 2001 to Aug. 2002. In the survey productivity and ecological preferences of the dominant species of brown algae include Cystoseira myrica, Sargassum boveanum, Padina australis, and Colpomenia sinusa were studied along the coast of the area. Tree station were selected for the study and the total biomass of brown algae (gr dw / m2 / year) of the tree station were 27357 (station 1), 10860 (station 2) and 6462 (station 3) respectively the result showed that the above species are main biomass producer of brown algae at the area. Each species have specific temporal and spatial distribution. Substratum, depth, temperature, light and tide level are main factors influencing the productivity and distribution of the species.
