Abstract :
Khuzestan coastal waters have high fisheries potential and ecological importance. Since different
sources of stress exist in this area, the present study was conducted to evaluate ecological quality and to
determine health status in Khuzestan coastal sediments based on benthic communities and their
biological parameters. Seasonal sampling was done from 20 creeks of Khur-e-Mussa area in Khuzestan
coastal waters by 0.125 m2 Peterson grabsampler during winter 2008 to autumn 2009. Macro–
invertebrates were separated, sorted and identified to the lowest possible taxon. In addition, biological
parameters such as diversity, richness, biomass and abundance were calculated. The results were
analyzed using univariate analysis method, ABC (Abundance–Biomass Curve). The most abundant
groups were polychaets (58%), crustaceans (25%) and mollusk (9%), respectively. The ABC plots
showed that majority ef creeks could be classified as moderately disturbed and polluted. The ranges of
Hʹ diversity index values in majority of stations indicated moderate ecological status.
