Abstract：
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.
摘要：
人工鱼礁被广泛部署用于渔业增强和海洋保护。对人工鱼礁的影响进行全面评估可以最大程度地减少盲目开发人工鱼礁的负面影响。我们检查了祥云湾人工鱼礁附近和距离人工鱼礁<5m的小型生物群落和底栖环境，渤海,中国。我们在人工礁旁边发现了最高的meiofaunal丰度。Shannon-Wiener和Pielou指数在距人工鱼礁的不同距离之间没有显着差异。人工鱼礁的存在阻碍了周围的流动，并为双壳类动物和海带提供了额外的基质，这可能会导致更细的沉积物和周围的有机物富集。沉积物粒度和总有机质是影响小型动物的最重要参数。我们建议形状，材料,人工鱼礁的配置和位置应与避免盲目扩散的特定目标相关。
