Authors

Abstract

This study was carried out to determine the Seaweed biomass in the coast of Sistan & Baluchestan Province. Beris, Chabahar, Pozm and Tang were introduces as high density zones and Jood & Lipar were selected as low density zones.

From 354.2 km of investigated coastal area, among this, 18.2 km were high density zone and 281.5 km were low density zone. Three transects were fixed in studies area and sampling randomly were done monthly. The samples were measured in area after being cleaned, and separating. During this research, 9 genus were collected. Among these seaweeds, 2 genus were green algea (composed of 2 families and 2 orders), 6 genera of brown algae (composed of 3 families and 3 orders) and 1 genus of red algae.

Wet biomass of Sargassum genus in the total area of Sistan & Baluchestan coasts was 445.9 tons in 2012. Among this biomas, 269.1 tons (%60.35) was found in high density area and 176.8 tons (%39.65) in low density zone. The maximum biomass was obtained 270.4 tons (high density zone: 155.5 and low density zone: 114.9 tons) in Dec. and the lowest biomass was obtained 3.5 tons in March.
