Abstract

This study investigates the endohelminth parasites of three-spined stickleback, Gasterosteus aculeatus, across marine, anadromous, and freshwater populations in the White Sea (Russia). A total of 241 sticklebacks were collected in Velikaya Salma Strait during 2022-2024. Thirteen helminth species were identified using morphological and molecular methods. Genetic analysis confirmed the presence of Anisakis simplex sensu stricto, Hysterothylacium aduncum, Phyllodistomum folium, Brachyphallus crenatus, and Alloopistholecithum cf. salmonis. We identified variability in parasite communities between 2022+2023 and 2024 both within and between marine, anadromous and freshwater host populations. The most striking temporal changes were observed in the parasite communities of the anadromous stickleback population, which is probably due to the different periods of time spent by the fish in fresh water in the years studied. This study highlights differences in infection of marine, anadromous, and freshwater populations of three-spined stickleback, providing insights into host-parasite dynamics across different aquatic environments in the White Sea basin.

白海中海洋、溯河和淡水三棘棘鱼的内蠕虫(鳍形目:棘鱼科)。
本研究调查了俄罗斯白海三棘棘鱼(Gasterosteus aculeatus)在海洋、沼泽和淡水种群中的内层寄生虫。在2022-2024年期间,在Velikaya Salma海峡共收集了241条棘鱼。利用形态学和分子生物学方法鉴定了13种蠕虫。遗传分析证实存在狭义异尖线虫、aduncum Hysterothylacium、phyllodisstomum folium、Brachyphallus crenatus和Alloopistholecithum c.s armis。我们确定了2022+2023年至2024年期间,海洋、河流和淡水宿主种群内部和之间的寄生虫群落变化。最引人注目的时间变化是在溯河棘鱼种群的寄生虫群落中观察到的,这可能是由于在研究的年份中,鱼在淡水中度过的时间不同。本研究强调了三刺鱼在海洋、产卵和淡水种群中的感染差异,为白海盆地不同水生环境中的宿主-寄生虫动力学提供了见解。

期刊介绍: Journal of Helminthology publishes original papers and review articles on all aspects of pure and applied helminthology, particularly those helminth parasites of environmental health, medical or veterinary importance. Research papers on helminths in wildlife hosts, including plant and insect parasites, are also published along with taxonomic papers contributing to the systematics of a group. The journal will be of interest to academics and researchers involved in the fields of human and veterinary parasitology, public health, microbiology, ecology and biochemistry.
