Helminth Diversity in Teleost Fishes from the Area of the Ukrainian Antarctic Station “Akademik Vernadsky”, Argentine Islands, West Antarctica

Monitoring studies of the species diversity in marine ecosystems provide important data on ecological changes caused by global warming and anthropogenic influence. The present work was aimed to analyze helminths parasitic teleost fishes inhabiting area near Ukrainian Antarctic Station “Akademik Vernadsky” (Galindez Island, Argentine Islands, West Antarctica). During April–January 2014–2015 2019–2020, 156 specimens six fish (Notothenia coriiceps, N. rossii, Chaenocephalus aceratus, Parachaenichthys charcoti,Trematomus bernacchii, Harpagifer antarcticus) were examined. Totally, 21,166 31 helminth collected assigned five taxonomic groups: Monogenea (1 species), Digenea (10), Nematoda (5), Cestoda (4), Acanthocephala (11). Twenty-six found 14 27 P. charcoti, 23 Ch. 16 T. H. antarcticus. Larval stages anisakid nematodes prevailed community aceratus (66 %) charcoti (40 %), while other mostly infected with acanthocephalans,trematodes cestodes. communities can be used as a baseline for long-term monitoring parasites region Islands.
