Abstract A single specimen of the penaeid prawn Penaeus aztecus (Ives, 1891) was recorded in 2018 in the brackish zone of the Scheldt estuary near Antwerp (Belgium). The presence of this species, native to the West Atlantic, might result either from ships' ballast water coming from transatlantic boat shipping, from illegal import or from a considerable expansion leap northwards from the Mediterranean Sea, where this species has recently established and now has rapidly expanding invasive populations.

阿兹特克对虾，1891 年（甲壳纲，十足目），在斯海尔德河口（比利时）：对虾入侵的孤立记录还是先行者？

摘要 2018 年在安特卫普（比利时）附近的斯海尔德河口的咸淡水区记录了一个对虾对虾 (Ives, 1891) 的单个标本。这种原产于西大西洋的物种的存在可能是由于来自跨大西洋船只运输的船舶压载水、非法进口或从地中海向北大幅扩张的结果，该物种最近在那里建立并现在已经迅速扩大的入侵种群。
