摘要: 1 - The aim of this study was identifying macrobenthos biodiversity and an assessment the ecological quality status Bahrekan coast in Persian Gulf, using AMBI, Bentix indices according to softbottom marine benthic communities. Other indices, such as theShannon diversity index (H`) species richness ( S ) were also applied evaluated comparatively. 2 In total, 111 genus/species recognized, divided into 17 groups with gastropodas always dominant substrate all stations characterized muddy bottom. 3 macrobenthic animals their sensitivity increasing stress gradient, classified 5 groups. 4 Due high dominance Pyrgohydrobia sp., Tornatina Melinna Cossura sp. Sternaspis sp, values reduced. According results BI, Bentix, H`indices is slightly moderate pollution status.
