苏格兰北部设得兰群岛拥有高度活跃和多样化的海洋环境，当地的海洋产业构成了当地经济的重要组成部分。非本地物种造成损害的可能性很高。作为对设得兰非本土物种现状评估的一部分，2012年5月至2014年10月期间，在18个地点进行了一系列快速评估调查，并实施了定居小组监测方案。在本次调查中共发现8种非本地种，其中3种(Corella eumyota Traustedt，1882；Bugulina Simple ex Hincks，1886；Dasysiphia Japan onica(Yendo)Kim，2012)以前从未记录过。Scuba的观察还报告了1890年在自然底物上生长的日本裂殖藻的第一个英国记录。一项文献回顾显示，设得兰还记录了另外三种非本地物种，但在我们的调查工作中没有发现。这项研究的结果突出了非本地物种在区域范围内扩散的速度，而且越活跃的港口包含更多数量的非本地物种，这表明船体污垢和压载水交换可能用于运输非本地物种。
The Shetland Islands, northern Scotland, have a highly active and diverse maritime environment, and local marine industries form an important part of the local economy. The potential for damage caused by non-native species is high. As part of an assessment of the current status of non-native species in Shetland, a series of rapid assessment surveys, coupled with a settlement panel monitoring programme, were carried out at 18 sites between May 2012 and October 2014. Eight non-native species were detected in our surveys, three of which (Corella eumyota Traustedt, 1882; Bugulina simplex Hincks, 1886; and Dasysiphonia japonica (Yendo) Kim, 2012) had not been previously recorded. Observations by SCUBA also reported the first UK record of Schizoporella japonica Ortmann, 1890 growing on natural substrate. A literature review revealed three additional non-native species that have been documented in Shetland but were not detected in our survey work. The results from this study highlight the speed at which non-native species can spread over regional scales, and that more active harbours contain greater numbers of non-native species, indicating the potential of hull fouling and ballast water exchange for transporting non-native species.
