Non-indigenous species can become a problem for the ecosystem health, especially when their distribution grows to the detriment of native species. In this moment, they can become invasive species. In marine ecosystems, the maritime transport is the principal gate and corridor for the movement of alien species. The genetic identification, using barcoding tools, of different oyster species in ports of the remote French Polynesia islands and atolls, showed a significant increase of exotic versus native oyster species between 2011 and 2018. This supports the spread of exotic species with the maritime traffic as the main cause. Moreover, the 11% of inaccurate identification at species level obtained in this study shows the need to complete the genetic databases.

小心生蚝。热带太平洋岛屿非本土物种的快速发展

非本地物种可能成为生态系统健康的问题,尤其是当它们的分布增长对本地物种有害时。在这一刻,它们可以成为入侵物种。在海洋生态系统中,海上运输是外来物种移动的主要门户和走廊。使用条形码工具对偏远的法属波利尼西亚群岛和环礁港口的不同牡蛎品种进行的遗传鉴定显示,2011 年至 2018 年间,外来牡蛎品种与本地牡蛎品种相比显着增加。主要原因。此外,在本研究中获得的物种水平上 11% 的不准确识别表明需要完善遗传数据库。
