In October 2019, during Tropical Storm Lorenzo, an unusual bloom of Physalia physalis (commonly known as the Portuguese man o' war) appeared on the west coast of Ireland. The jellyfish were observed aggregating in high numbers surrounding salmon pens on two Atlantic salmon farms with tentacles extending underwater through the nets into the pens. Acute skin lesions and mortality were reported as a consequence of exposure to P. physalis on both sites. The impact of noxious zooplankton species such as P. physalis may pose a significant and more frequent threat in future if increased adverse weather events continue to transport these and other jellyfish outside their normal range. This is the first published record of Physalia physalis causing mortality in cultured fish.
2019 年 10 月，在热带风暴“洛伦佐”期间，爱尔兰西海岸出现了一种不寻常的葡萄牙僧帽水母（Physalia physalis）大量繁殖的现象。人们观察到这些水母大量聚集在两个大西洋鲑鱼养殖场的三文鱼围栏周围，触须通过网眼延伸到围栏下面的水中。两个养殖场都报告了因接触葡萄牙僧帽水母而导致的急性皮肤损伤和死亡。如果恶劣的浮游动物物种（如葡萄牙僧帽水母）的影响持续增加，并且更多的恶劣天气事件继续将这些水母和其他水母带离其自然分布范围之外，那么这种情况在未来可能会构成更频繁和更严重的威胁。这是葡萄牙僧帽水母导致养殖鱼类死亡的首例公开记录。
