A list of internal parasitic worms occurring in four fish species in environs of the Adelie Land is given. In total, 20 forms are listed, including 14 species occurring in fishes in the adult stage (11 Digenea, 2 Acanthocephala, 1 Nematoda) and six larval forms (3 Cestoda, 1 Acanthocephala, 2 Nematoda). Twelve species occurring as adults and two larval forms are specifically determined. One digenean species is not identified even to a family, one acanthocephalan species and one nematode larval form are determined to the genera, three cestode larval forms are determined only to the higher taxa. All species and larval forms previously recorded in the investigated area are present in the material; eleven ones are reported from environs of the Adelie Land for the first time.

Trematomus newnesi (Nototheniidae), a bentho-pelagic fish, caught off Adelie Land (eastern Antarctic) was examined for the presence of internal parasitic worms. These fishes were infected with 11 species and larval forms of parasites: Digenea (Macvicaria pennelli, Neolebouria terranovaensis, Genolinea bowersi, and Elytrophalloides oatesi), larval Cestoda (two forms of tetraphyllidean metacestodes, bilocular form and trilocular form, and diphyllobothriid plerocercoids), Acanthocephala (Metacanthocephalus camp- belli, M. johnstoni) and larval Nematoda (Contracaecum osculatum, C. radiatum). Larval cestodes were the dominant parasites, whereas acanthocephalans were relatively rare. Five species and larval forms were recorded also in fish caught in the Davis Sea. A check list of parasites of T. newnesi recorded in the eastern- and western Antarctic comprises 21 species and larval forms. Probably, T. newnesi plays an important role in life cycles of parasitic worms in the Antarctic.

The two bathydraconid species, Gymnodraco acuticeps and Cygnodraco mawsoni, caught in the Ross Sea (Antarctic summer 2002) were examined for internal parasites. All specimens (four G. acuticeps and one C. mawsoni) were infected. G. acuticeps harboured larval Cestoda (bilocular tetraphyllidean cercoids, diphyllobothriid plerocercoids) and Nematoda (Contracaecum spp.), acanthocephalan cystacanths and adult helminths (three species of Digenea and one species of Nematoda). Two specimens of C. mawsoni (including data from one additional specimen examined earlier) were infected by larval Cestoda (bilocular cercoid) and Nematoda (Contracaecum spp.) and adult helminths (three species of Digenea and one species of Nematoda). The present data are compared and discussed with the relevant literature data.
