Parasitological monitoring of the fish species in the CCAMLR Area 48

Parasitological study was conducted onboard the Ukrainian trawler “MORE SODRUZHESTVA”, which fished Antarctic krill during the cruise from the end of December 2020 till the end of March 2021. All fish specimens collected and examined were infected with helminths of five taxonomic groups (Nematoda, Cestoda, Trematoda, Acanthocephala or Monogeneans). Two groups of helminths dominated in the helminth communities – nematodes (consists from 28 to 61% of the total parasite number) and cestodes (from 15 to 22%); trematodes and acanthocephalans accounted for 3 to 8% of the total number of helminths found in different species of fish.
