在2000年5月至2004年11月期间，在42艘到访或作业于新西兰的船只的海箱中，共鉴定出150种不同的生物，包括一种植物和12个动物门。49%的生物体是不动的，42%是移动的，剩下的9%是久坐不动的。十足类是最具代表性的群体，在79%的容器中有19种。40%的生物是新西兰本土的，15%是引进的，10%是非本土的，35%是未知来源的。海箱具有以下潜力：(1)跨越海洋边界在国家之间转移非本地生物；(2)在国内分散本地和引进的生物。成年可移动生物的出现尤其重要，这表明在散布某些海洋物种方面，海箱可能比压载水或船体污垢更重要。这些发现强调需要评估和管理整个船舶的生物安全风险，而不是孤立地评估和管理不同机制（即压载水、船体污垢、海箱等）。(c) 2007 Elsevier Ltd.版权所有。
A total of 150 different organisms, including one plant species and 12 animal phyla were identified from sea-chests of 42 vessels visiting or operating in New Zealand between May 2000 and November 2004. Forty-nine percent of organisms were sessile, 42% mobile adults and the remaining 9% sedentary. Decapods were the most represented group with 19 species present among 79% of vessels. Forty percent of organisms were indigenous to New Zealand, 15% introduced, 10% non-indigenous, and 35% of unknown origin. Sea-chests have the potential to (1) transfer non-indigenous organisms between countries across oceanic boundaries; and (2) disperse both indigenous and introduced organisms domestically. The occurrence of adult mobile organisms is particularly significant and indicates that sea-chests may be of greater importance than ballast water or hull fouling for dispersing certain marine species. These findings emphasise the need to assess and manage biosecurity risks for entire vessels rather than different mechanisms (i.e., ballast water, hull fouling, sea-chests, etc.) in isolation.(c) 2007 Elsevier Ltd.
