摘要

本研究描述了葡萄牙福尔摩沙岛自然公园(NPRF)中皇家黄瓜 Parastichopus regalis(Cuvier,1817 年)的存在。在该浅潮间带泻湖内 3 米深处进行的一次水肺潜水监测中,观察到了一只个体。出现这种情况的最合理解释是拖网渔船从渔场返回母港时将其拒之门外。这种海洋物种在环礁湖外分布较深,通常作为副渔获物被捕获,随后被丢弃。这项研究还提醒我们注意非土著物种的日益增多和新物种入侵的威胁,强调有必要采取生物安全措施,如渔民在处理丢弃物时的良好做法,以避免在这一脆弱的沿海海洋生境中引入新物种。

A foreign settler: the anthropogenic displacement of sea cucumbers through fisheries discards
This study describes the presence of the royal cucumber Parastichopus regalis (Cuvier, 1817) in The Natural Park of Ria Formosa (NPRF), Portugal. A single individual was observed during a monitoring scuba dive at a depth of 3 m inside this shallow mesotidal lagoon. The most plausible explanation for this occurrence is attributed to the rejection by trawlers when returning to their home port from their fishing grounds. This marine species has a deeper distribution outside the lagoon and is commonly captured as by-catch and subsequently discarded. This study also alerts us to the growing presence of non-indigenous species and the emergent threat of new invasions, highlighting the need to adopt biosecurity measures, like good practices for fishers when dealing with discards to avoid new species introductions in this fragile coastal marine habitat.
