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.
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.
