Artificial reefs have been widely deployed in the northern Yellow Sea. However, the differences in the ecological benefits on different types of artificial reef habitats are still poorly understood. In this study, the temporal and spatial differences on benthic fish communities were evaluated among concrete artificial reef habitat (CAR), rocky artificial reef habitat (RAR), ship artificial reef habitat (SAR) around Xiaoshi Island in northern Yellow Sea. The results indicated that all three types of artificial reef habitats can enhance the diversity variables of benthic fish communities, and fish abundance, species richness and Shannon-Wiener index of CAR were generally better than the other two. CAR and RAR hosted similar community composition of benthic fish, and all types of habitats showed significant differences in community composition between winter-spring and summer-autumn. Environmental factors, especially water temperature, can also affect the community composition by affecting the migration of temperature-preferred species. Overall, the enhancement effects of artificial habitats on fisheries productivity varied with fish species and reef types. This study will help to understand the ecological effects of different types of artificial reefs in northern Yellow Sea, and then could give an insight for scientific construction of artificial reefs in this region.
人工鱼礁在黄海北部得到了广泛的应用。然而，不同类型人工鱼礁栖息地的生态效益差异仍不甚清楚。本研究评估了黄海北部小石岛周围的混凝土人工鱼礁（CAR）、岩石人工鱼礁（RAR）和船舶人工鱼礁（SAR）三种人工鱼礁生境中底栖鱼类群落的时空差异。结果表明，三种类型的人工鱼礁栖息地都可以提高底栖鱼类群落的多样性变量，CAR 的鱼类丰度、物种丰富度和 Shannon-Wiener 指数普遍优于其他两种。CAR 和 RAR 具有相似的底栖鱼类群落组成，所有类型的栖息地在冬春和夏秋两季的群落组成上都有显著差异。环境因素，特别是水温，也可以通过影响温度偏好物种的迁移来影响群落组成。总体而言，人工栖息地对渔业生产力的增强效果因鱼类物种和礁型而异。本研究有助于了解黄海北部不同类型人工鱼礁的生态效应，从而为该地区人工鱼礁的科学建设提供参考。
