Coastal reclamation and modifications are extensively carried out in Bahrain, which may physically smother the coastal and subtidal habitats resulting in changes to abundance and distribution of macrobenthic assemblages. A microcosm laboratory experiment using three common macrobenthic invertebrates from a proposed reclaimed coastal area was preformed to examine their responses to mud burial using marine sediment collected from a designated borrow area. Significant difference in numbers of survived organisms between control and experimental treatments with a survival percentage of 41.8% for all of the selected species was observed. The polychaete Perinereis nuntia showed the highest percentage of survival (57.1%) followed by the bivalve Tellinavaltonis (42.3%) and the gastropod Cerithidea cingulata (24.0%). Quantifying species responses to sediment burial resulted from dredging and reclamation will aid in predicting the expected ecological impacts associated with coastal developments and subsequently minimizing these impacts and maintaining a sustainable use of coastal and marine ecosystems in the Arabian Gulf.
在巴林，海岸填海造地和改造工程广泛开展，这可能会使沿海和潮间带生境受到物理性窒息，从而导致大型底栖生物组合的丰度和分布发生变化。为了研究拟填海区三种常见大型底栖无脊椎动物对泥沙掩埋的反应，使用从指定取土区采集的海洋沉积物，进行了一个微宇宙实验室实验。在对照和实验处理之间，存活生物数量存在显著差异，所有选定物种的存活率为 41.8%。多毛类环节动物 Perinereis nuntia 的存活率最高（57.1%），其次是双壳类 Tellinavaltonis（42.3%）和腹足类 Cerithidea cingulata（24.0%）。量化疏浚和填海造地造成的物种对泥沙掩埋的反应，将有助于预测与沿海开发相关的预期生态影响，从而最大限度地减少这些影响，并维持海湾地区沿海和海洋生态系统的可持续利用。
