Abstract：
The present study is the first to analyse the parasite fauna of sole Solea solea, dab Limanda limanda, hake Merluccius merluccius, whiting Merlangius merlangus, and plaice Pleuronectes platessa in the Pomeranian Bay, as well as saithe Pollachius virens from the Szczecin Lagoon (Poland). The aim of this study was to determine the occurrence of parasites in migrating and rare fish in the Pomeranian Bay and the Szczecin Lagoon and to determine the composition of the diet of these fish. The fish for analysis were obtained in the years 2010-2019. The typical marine nematode Capillaria (Procapillaria) gracilis, rarely recorded in Poland, was found, in addition to the following parasites: Ichthyophonus hoferi, Trichodina jadranica, Diphyllobothrium sp., Dichelyne (Cucullanellus) minutus, Raphidascaris acus, Anisakis simplex, Contracaecum osculatum, Hysterothylacium aduncum, Pseudoterranova decipiens, and Echinorhynchus gadi. Because the fish species analysed in the study are not typically present in the Baltic (with the exception of plaice), and because we do not know how long they feed while they are in the Baltic, we cannot be certain which parasites they acquired in the water bodies analysed in the study and which were introduced during the migration of fish. Although these fish are outside of their normal geographic range (except for plaice), in the new environment, there were enough suitable intermediate hosts for the parasites of these fish to complete their life cycle and survive.
摘要：
本研究是首次分析唯一的SoleaSolea的寄生虫动物群，DabLimandaLimanda,哈克·梅鲁齐乌斯·梅鲁齐乌斯，梅尔兰吉斯·梅尔兰格斯，和波美拉尼亚湾的plaicepleuronectesplatessa，以及Szczecin泻湖（波兰）的saithePollachiusvirens。这项研究的目的是确定Pomeranian湾和什切青泻湖中迁徙和稀有鱼类中寄生虫的发生，并确定这些鱼类的饮食组成。用于分析的鱼是在2010-2019年获得的。典型的海洋线虫毛细管（Procapillaria）gracilis，很少在波兰记录，被发现,除了以下寄生虫外：Ichthyophonushoferi，TrichodinaJadranica,Diphyllobothriumsp.,双冷树（Cucullanellus），Raphidascarisacus，单形异己,奥氏梭菌,赤霉病，假性蜕膜，和Echinorhynchusgadi。由于研究中分析的鱼类通常不存在于波罗的海（除了plaice），因为我们不知道它们在波罗的海时进食多长时间，我们无法确定它们在研究中分析的水体中获得了哪些寄生虫，以及哪些是在鱼类迁徙过程中引入的。尽管这些鱼超出了它们的正常地理范围（除了plaice），在新环境中,这些鱼的寄生虫有足够合适的中间宿主来完成它们的生命周期并存活。
