The addition of man-made structures to the marine environment is known to increase the physical complexity of the seafloor, which can influence benthic species community patterns and habitat structure. However, knowledge of how deployed tidal energy device structures influence benthic communities is currently lacking. Here we examined species biodiversity, composition and habitat type surrounding a tidal energy device within the European Marine Energy Centre test site, Orkney. Commercial fishing and towed video camera techniques were used over three temporal periods, from 2009 to 2010. Our results showed increased species biodiversity and compositional differences within the device site, compared to a control site. Both sites largely comprised of crustacean species, omnivore or predatory feeding regimes and marine tide-swept EUNIS habitat types, which varied over the time. We conclude that the device could act as a localised artificial reef structure, but that further in-depth investigations are required.
向海洋环境中添加人造结构会增加海底的物理复杂性，这可能会影响底栖物种群落模式和栖息地结构。然而，目前尚缺乏关于已部署的潮汐能装置结构如何影响底栖生物群落的知识。在此，我们研究了欧洲海洋能源中心测试场地（奥克尼）内一个潮汐能装置周围的物种生物多样性、组成和栖息地类型。在2009年至2010年的三个时间段内，使用了商业捕鱼和拖曳式摄像机技术。我们的结果表明，与对照场地相比，装置场地内的物种生物多样性增加且组成存在差异。两个场地主要都由甲壳类物种、杂食或捕食性摄食方式以及海洋潮汐冲刷的欧洲生态信息系统（EUNIS）栖息地类型组成，这些随时间而变化。我们得出结论，该装置可作为局部人工礁结构，但还需要进一步深入研究。
