In total, 400 bony fishes of 32 species (7 families) were examined. Acanthocephalans occurred in 55 host specimens of 15 species. Five species were recognised, including 3 echinorhynchid species maturing in fish, Metacanthocephalus campbelli (Leiper et Atkinson, 1914), M. dalmori Zdzitowiecki, 1983 and Echinorhynchuspetrotschenkoi (Rodjuk, 1984), as well as cystacanths of 2 polymorphid species maturing in seals, Corynosoma bullosum (Linstow, 1892) and C. pseudohamanni Zdzitowiecki, 1984. All species were found in fish in the Weddell Sea for the first time. M. dalmori, E. petrotschenkoi and C. bullosum were not previously recorded in the high Antarctic. Out of 26 host/parasite relationships, 24 are new. The level of infection was very low. Only 114 acanthocephalan specimens were found, with the maximum intensity of 12 cystacanths in one Trematomus pennelli. C. bullosum was the most abundant species (53% of all specimens). Out of 11 fish species examined in numbers of 18-46 specimens, only 6 were infected. Trematomus scotti was the most strongly infected - prevalence 54%, relative density 1.04.
