Biomass variation in red algae along the tidal areas of Bushehr province

This study was carried out during October 2008 to July 2009 in Bushehr coastal areas at 6 stations to examine biomass variations in red algae. Algal samples were collected by hand from intertidal zone, during low tide. Quadrates 50 ×50cm each were marked randomly in the study area, and all algal samples were collected within the quadrate area. Total biomass was found to be 2598.91g.m belonging to 15 Rhodophyta species. The maximum biomass was 1114.32g. m (43%) observed at the Nirougah station. Summer showed maximum biomass 1076.36g. m (41%) compared to other seasons. Results of this study showed Rhodophyta species are dispersed more in mid littoral and sub-tidal areas. Also, the maximum biomass was observed in the sub-tidal zone. The highest biomass of the species belonged to Grascilaria canaliculata.
