The garfish Belone belone (Linnaeus, 1760) is a marine fish which can be found in the shallow waters of the Baltic Sea in the spring and summer spawning period. In 2010 and in 2016, 73 specimens of garfish collected in the Gulf of Gdansk (southern Baltic Sea) were examined for the presence of helminths. The fish were found to support the nematode Anisakis simplex (Rudolphi, 1809) L3, Hysterothylacium aduncum (Rudolphi, 1802) L4, ad., Contracaecum sp. L3 as well as the acanthocephalan Echinorhynchus gadi Zoega in Müller, 1776. For all garfish caught in 2010 and 2016, the overall prevalence of infection by all parasites was 38.4%, with a mean intensity of 2.9 (range 1-5). The dominant parasites were H. aduncum (20.5%, 1.8) and E. gadi (17.8%, 2.1). This study constitutes the first record of Contracaecum larvae in garfish in the Polish exclusive economic zone of the Baltic Sea.
颌针鱼（Belone belone，林奈，1760年）是一种海洋鱼类，在春季和夏季产卵期可在波罗的海浅水区发现。2010年和2016年，对在格但斯克湾（波罗的海南部）采集的73个颌针鱼样本进行了寄生虫检查。发现这些鱼体内有线虫简单异尖线虫（Anisakis simplex，鲁道夫，1809年）L3期幼虫、钩状异尖线虫（Hysterothylacium aduncum，鲁道夫，1802年）L4期幼虫、ad.、对盲囊线虫属（Contracaecum sp.）L3期幼虫以及棘头虫多棘吻棘头虫（Echinorhynchus gadi，策加于米勒，1776年）。对于2010年和2016年捕获的所有颌针鱼，所有寄生虫的总体感染率为38.4%，平均感染强度为2.9（范围1 - 5）。优势寄生虫为钩状异尖线虫（20.5%，1.8）和多棘吻棘头虫（17.8%，2.1）。本研究是波罗的海波兰专属经济区内颌针鱼体内对盲囊线虫幼虫的首次记录。
