Macrobenthos-sediment composition relationships Hormozgan Province coastal waters, Persian Gulf

Macrobenthos are benthic animals that live in or on the bottom sediments which used as a bioindicators to assess the presence of contaminants, in natural aquatic systems. This study aimed to achieve the relationship between sediment composition and macrobenthic communities, distribution. Sampling was done monthly in 2011-12 by a powerboat, and VanVeen grab with 0.04 cross section, were used for sampling from sediment. Sampling areas was Bandar Abbas, Jask and Lengeh coastal waters in Hormozgan Porvince. Results showed that Silt was dominant in sediment of Bandarabbas and Sand was dominant in Lengeh and Jask sediment in coastal waters. Data Analysis indicated that there was a significant relationship between macrobenthos communities and silt (P<0.01) and sand (P<0.05). In addition, there was no relationship between macrobenthos communities and organic materials.
