Abstract

Macro benthic invertebrate distribution and abundance in northern creeks of Boushehr province were analyzed by seasonal sampling from autumn 2000 till summer 2001. Sampling was carried out of sediments from bottom of nine stations which located in creeks and one control station in the sea by using of Van Veen Grab sampler.
In additional, eight groups of macro benthos were identified which the most abundant populations among them were Gastropoda (51%), Bivalvia and Polychaeta (17.4%) and Amphipoda (5.3%) respectively. The maximum density of macro benthos was 2378ind/m2 in spring and the minimum was 1174ind/m2 in autumn and also maximum and minimum biomass was 79.06g/m2 in summer and l7.72g/m2 in winter. The average wet weight of macro fauna biomass was 49.95 (±33.6)g/m2.
