Introduced species have a major impact on freshwater ecosystems, particularly on islands. Numerous fish species have been introduced in Corsica (Mediterranean island, southern France) as part of planned programs or clandestinely. The introduction of non-native freshwater fish species can have a range of impacts on the recipient ecosystem, including through the co-introduction of its pathogens. A sample of introduced perch Perca fluviatilis Linnaeus, 1758 from the artificial reservoir of Padula was examined following a report of parasites by an angler. The analyses revealed the occurrence of Eustrongylides sp. (Nematoda) and Clinostomum complanatum (Digenea), two zoonotic parasites in P. fluviatilis. Both parasites are reported for the first time in France. Eustrongylides sp. and C. complanatum may have been introduced with their fish intermediate hosts or through their final bird hosts. The occurrence of the two parasites raises concerns from both a veterinary and human health perspective as they can use a wide range of amphibians as intermediate hosts and can be acquired in humans through the consumption of raw or undercooked fish.
引入物种对淡水生态系统，特别是对岛屿有重大影响。科西嘉岛（法国南部的地中海岛屿）已经引入了许多鱼类物种，作为计划项目的一部分或秘密引入。非本地淡水鱼类物种的引入会对受纳生态系统产生一系列影响，包括与其病原体的共同引入。在一名钓鱼者报告寄生虫后，对来自帕杜拉人工水库的引入鲈鱼 Perca fluviatilis Linnaeus, 1758 进行了检查。分析结果显示，Eustrongylides sp.（线虫）和 Clinostomum complanatum（吸虫）在 P. fluviatilis 中存在。这两种寄生虫在法国都是首次报道。Eustrongylides sp. 和 C. complanatum 可能是随着它们的鱼类中间宿主或最终的鸟类宿主一起引入的。这两种寄生虫的出现引起了兽医和人类健康的关注，因为它们可以使用多种两栖动物作为中间宿主，并且可以通过食用生的或未煮熟的鱼而在人类中获得。
