Abstract

The lake brown trout is a salmonids fish regarded as a stationary form of the migratory trout. Within 2003-2004, 31 lake brown trout (Salmo trutta lacustris L.) from Lake Wdzydze (Poland), were examined for the presence of parasites following commonly used procedures. The parasites found represented Digenea: Diplostomum sp., Posthodiplostomum cuticola (Nordmann, 1832), Sphaerostomum globiporum (Rudolphi, 1802); Cestoda: Eubothrium crassum (Bloch, 1779), Triaenophorus nodulosus (Pallas, 1781); Acanthocephala: Acanthocephalus lucii (Müller, 1776); Copepoda: Ergasilus sieboldi Nordmann, 1832, and Hirudinea: Piscicola geometra (Linnaeus, 1761). The overall infection level amounted to 96.7%, 249.4, and 1-440. The copepod E. sieboldi was the most frequent parasite (93.5%, 257.4, 64-438). Lake brown trout from the Lake Wdzydze are very heavily infected by parasites dominated by the copepod E. sieboldi.

摘要

湖红点鲑是一种鲑科鱼类，被视为洄游型鳟鱼的定居形态。在2003年至2004年期间，按照常用程序对来自波兰Wdzydze湖的31条湖红点鲑（Salmo trutta lacustris L.）进行了寄生虫检查。发现的寄生虫包括复殖吸虫：双穴吸虫属、后双穴吸虫（诺德曼，1832年）、球形球口吸虫（鲁道夫，1802年）；绦虫：粗颈绦虫（布洛赫，1779年）、结节三歧绦虫（帕拉斯，1781年）；棘头虫：鲁氏棘头虫（米勒，1776年）；桡足类：西氏鱼虱（诺德曼，1832年），以及蛭纲：尺蠖鱼蛭（林奈，1761年）。总体感染水平分别为96.7%、249.4以及1至440。桡足类西氏鱼虱是最常见的寄生虫（93.5%、257.4、64至438）。来自Wdzydze湖的湖红点鲑受到以桡足类西氏鱼虱为主的寄生虫的严重感染。
