During parasitological studies of the invasive round goby fish species Apollonia melanostoma (Pallas, 1814) from the Danube River in 2007 the digenean Bucephalus polymorphus Baer, 1827 was detected for the first time in Austria. Encysted metacercariae of the parasite were found on the fins, skin and gills of the fish. The occurrence of the parasite is strictly dependant on the zebra mussel Dreissena polymorpha (Pallas, 1771), which acts as the obligatory first intermediate host in its life cycle. The mussel has also invaded Austrian waters, but has appeared in 1870 already. It will not be possible to establish whether the parasite was introduced to Austria with the gobies, or has arrived earlier, but it should be the subject of future investigations to ascertain whether the parasite will be able to establish a firm population in Austria, and whether this introduction puts additional pressure on the native fish populations.
在对多瑙河入侵性圆鳍鱼物种 Apollonia melanostoma（Pallas，1814）进行寄生虫学研究时，于 2007 年首次在奥地利发现了寄生的多形双腔吸虫 Bucephalus polymorphus Baer，1827。在鱼的鳍、皮肤和鳃上发现了该寄生虫的囊蚴。这种寄生虫的发生严格依赖于斑马贻贝 Dreissena polymorpha（Pallas，1771），它在其生命周期中充当必需的第一中间宿主。贻贝也已入侵奥地利水域，但早在 1870 年就已出现。目前还无法确定寄生虫是否与圆鳍鱼一起被引入奥地利，或者是否更早到达，但未来的调查应该确定寄生虫是否能够在奥地利建立稳定的种群，以及这种引入是否会对当地鱼类种群造成额外的压力。
