Artificial structures associated with shipping and boating activities provide habitats for a diverse suite of non-indigenous marine species. Little is known about the proportion of invader success in nearby waters that is attributable to these structures. Areas close to piles, wharves and piers are likely to be exposed to increasing levels of propagule pressure, enhancing the recruitment of non-indigenous species. Recruitment of non-indigenous and native marine biofouling taxa were evaluated at different distances from a large commercial shipping pier. Since artificial structures also represent a desirable habitat for fish, how predation on marine invertebrates influences the establishment of non-indigenous and native species was also evaluated. The colonisation of several non-indigenous marine species declined rapidly with distance from the structure. Little evidence was found to suggest that predators have much influence on the colonisation success of marine sessile invertebrate species, non-indigenous or otherwise. It is suggested that propagule pressure, not predation, more strongly predicts establishment success in these biofouling assemblages.
与航运和划船活动相关的人工结构为各种非本地海洋物种提供了栖息地。人们对这些结构导致附近水域入侵物种成功的比例知之甚少。靠近桩、码头和码头的区域可能会受到越来越多的繁殖体压力的影响，从而促进了非本地物种的招募。在远离大型商业航运码头的不同距离处，评估了非本地和本地海洋生物污损类群的招募情况。由于人工结构也代表了鱼类的理想栖息地，因此还评估了鱼类捕食对海洋无脊椎动物的建立如何影响非本地和本地物种的建立。几种非本地海洋物种的定殖随着与结构的距离迅速下降。几乎没有证据表明捕食者对海洋固着无脊椎动物物种（无论是否为本地物种）的定殖成功率有多大影响。有人认为，繁殖体压力而不是捕食更能预测这些生物污损组合中的建立成功率。
