越来越多的科学和旅游船只正在进入南极地区，并有可能带来目前在该地区没有发现的一系列生物。人们对这种引进的频率或与之相关的物种的身份和生存情况知之甚少。在这项研究中，我们报告的调查结果，检查的南非国家南极方案供应船，SA 'Agulhas'，而该船是在干船坞在2006年6月的海箱。通过对贻贝（Mytilus gallo-provincialis（Lamarck））壳长的推断，推测了个体的年龄，结果表明，一些个体在多次运输到南极地区后仍然存活。这些发现令人关切，并表明南极研究和供应船是海洋非本地物种进入该区域的重要媒介。
Increasing numbers of scientific and tourist vessels are entering the Antarctic region and have the potential to bring with them a range of organisms that are not currently found in the region. Little is known about the frequency of such introductions or the identity and survivorship of the species associated with them. In this study, we report the findings of an inspection of the sea chests of the South African National Antarctic Programme supply vessel, the SA 'Agulhas', while the vessel was in dry dock in June 2006. Large populations of a known invasive mussel, Mytilus gallo-provincialis (Lamarck), were found. By extrapolating from shell length, the age of individuals was estimated, the results of which suggest that some specimens have survived transportation to the Antarctic region on multiple occasions. These findings are cause for concern and demonstrate that Antarctic research and supply vessels are important vectors for marine non-indigenous species into the region.
