During a parasitological survey of two non-native fish species-racer goby Neogobius gymnotrachelus and monkey goby Neogobius fluviatilis-in the Włocławek Reservoir on the lower Vistula River, the monogenean Gyrodactylus proterorhini was recorded for the first time in Poland, and for the first time, the racer goby was listed as the parasite host. Specimens of G. proterorhini were detected on body surface, fins, and gills of the fish studied. In 2006, the monkey goby was infected with the prevalence 41%, racer goby with the prevalence of 47%, at maximal intensity of 6 and 9 parasites per fish, (respectively). The infection level in relation to the fish size and sampling season was also discussed. The presented study supports the hypothesis of progressive introduction of the parasite with gobiids to the colonized areas.
在对下维斯瓦河的沃洛科拉姆斯克水库中的两种非本地鱼类——雷蛙 Neogobius gymnotrachelus 和猴蛙 Neogobius fluviatilis——进行寄生虫学调查期间，首次在波兰记录到了单殖吸虫 Gyrodactylus proterorhini，并且首次将雷蛙列为寄生虫宿主。在研究的鱼类的体表、鳍和鳃上检测到了 G. proterorhini 标本。2006 年，猴蛙的感染率为 41%，雷蛙的感染率为 47%，每条鱼的最大强度分别为 6 和 9 个寄生虫。还讨论了与鱼类大小和采样季节有关的感染水平。本研究支持寄生虫随虾虎鱼逐渐传入被殖民地区的假说。
