| Abstract |
The Shetland Islands, northern Scotland, have a highly active and diverse maritime environment, and local marine industries form an important partof 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-nativespecies in Shetland, a series of rapid assessment surveys, coupled with a settlement panel monitoring programme, were carried out at 18 sitesbetween 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 SCUBAalso reported the first UK record of Schizoporella japonica Ortmann 1890 growing on natural substrate. A literature review revealed threeadditional non-native species that have been documented in Shetland but were not detected in our survey work. The results from this study highlightthe 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. |
