N2 - During the Czech Antarctic expedition 2014 field investigations were carried out to contribute to the knowledge on fish parasites in Antarctica. From January to March 2014 in total 102 specimens of six fish species (Notothenia coriiceps – 14 individuals, Trematomus bernacchi – 30, T. hansoni – 32, T. newnesi – 23, Parachaenichthys charcoti - 2, Pagotenia borshgrewincki – 1 specimen) were examined for parasites. The fish were caught with gill nets and fish rods in the Prince Gustav Channel (depth about 5–25 m) in front of the Johann Gregor Mendel Station on the James Ross Island. Altogether 7740 metazoan parasites (including ectoparasites: Monogenea – 1326, Crustacea – 44, Hirudinea – 20, and endoparasites: Nematoda – 3263, Acanthocephala – 2053, Cestoda – 758 and Trematoda – 276) were found. Also Myxozoa were present in 10 fish individuals. The spatial distribution on fish gills of 1157 monogeneans (family Gyrodactylidae, Dactylogyridae and Capsalidae) was determined. Mean overall parasite abundance across the host species was 76. Maximum abundance (565) was observed in Notothenia coriiceps, which was the most parasitized host species with the mean parasite abundance of 117 and prevalence of 100 %. The lowest parasite abundance (51) was recorded in T. bernacchi. The prevalence in Trematomus spp. was 100 % with the mean abundance 71. All fish were infected with high intensities of nematodes (mean abundance 37, prevalence 97 %). The prevalence of Corynosoma spp. (Acanthocephala) ranged from 39% in T. newnesi to 100% in N.coriiceps. Crustacea and Hirudinea were found rarely and mainly on T. bernacchi and N.coriiceps.
