Rapid assessment surveys of non-indigenous species (NIS) of sessile invertebrates were made at seven marinas in NW France and 10 marinas in SW England in 2010, and repeated in 2013. Fourteen NIS were recorded, 12 of which were seen on both coasts. Site occupancy differed between the opposite sides of the western English Channel. In Brittany, most species occurred at most sites in both 2010 and 2013. In 2010, site occupancy in Devon & Cornwall was distinctly lower; by 2013, the difference compared to Brittany had narrowed considerably, largely because of rapid colonisation of additional sites by species that were infrequent in 2010. Three more of the recent NIS are present in Devon & Cornwall but have still not become widespread. It is concluded that the recently introduced fouling animals studied here are longer established in NW France than in SW England, and have probably spread northwards across the Channel.
2010 年和 2013 年，在法国西北部的 7 个码头和英格兰西南部的 10 个码头对固着无脊椎动物的非本地物种（NIS）进行了快速评估调查。记录到了 14 种 NIS，其中 12 种在两个海岸都有发现。英吉利海峡两岸的地点占有率不同。在布列塔尼，大多数物种在 2010 年和 2013 年的大多数地点都有出现。2010 年，德文郡和康沃尔郡的地点占有率明显较低；到 2013 年，与布列塔尼相比，这一差异已大大缩小，主要是因为一些物种在 2010 年不太常见，但已迅速在更多地点定居。德文郡和康沃尔郡还有另外三种最近的 NIS，但尚未广泛分布。结论是，与在英格兰西南部相比，这里研究的最近引入的污损动物在法国西北部的建立时间更长，并且可能已经向北穿过英吉利海峡传播。
