Artificial reefs are widely deployed for fishery enhancement and marine conservation. A comprehensive assessment on the effects of artificial reefs could minimize the negative consequence of blindly developing artificial reefs. We examined the meiofaunal community and benthic environment adjacent to and <5 m from artificial reefs in Xiangyun Bay, Bohai Sea, China. We found the highest total meiofaunal abundance beside the artificial reef. Shannon-Wiener and Pielou indexes had no significant difference among different distances from the artificial reefs. The presence of artificial reefs impeded the surrounding flow and provided additional substrate for bivalves and kelps, which could cause finer sediment and organic enrichment around it. Sediment grain size and total organic matter were the most important parameters influencing the meiofauna. We suggest that the shape, material, configuration and location of artificial reefs should be related with a specific goal to avoid mindless proliferation.
人工鱼礁被广泛用于渔业增值和海洋保护。对人工鱼礁的影响进行全面评估，可以最大限度地减少盲目开发人工鱼礁的负面影响。我们研究了中国渤海象山湾人工鱼礁附近和距人工鱼礁 5 米范围内的小型底栖动物群落和底栖环境。我们发现人工鱼礁旁的小型底栖动物总丰度最高。人工鱼礁不同距离处的 Shannon-Wiener 和 Pielou 指数没有显著差异。人工鱼礁的存在阻碍了周围的水流，并为双壳类动物和海带提供了额外的基质，这可能导致其周围的沉积物更加细腻和有机物更加丰富。沉积物粒径和总有机物质是影响小型底栖动物的最重要参数。我们建议人工鱼礁的形状、材料、结构和位置应与特定目标相关联，以避免盲目扩张。
