Description
Summary:Abstract: The infections of four fish species, Trematomus newnesi, T. bernacchii, Lindber− gichthys nudifrons and Harpagifer antarcticus with parasitic worms, in the coastal zone off the Vernadsky Station (Argentine Islands, West Antarctica) are described. Data on infec− tions are compared with previous results from Admiralty Bay at the South Shetland Islands. Indices of infection are for each host–parasite relationship. In total, 16 taxa of parasites were recorded: 6 digeneans, 3 larval cestodes, 4 (adult and cystacanth) acanthocephalans, and 3 (adult and larval) nematodes. Fifteen of them have been previously recorded in Notothenia coriiceps from this area. Hence, the number of parasitic taxa recorded in this region in− creased from 21 to 22. Either the digenean Macvicaria georgiana or acanthocephalan Corynosoma pseudohamanni were dominants in different hosts. Trematomus bernacchii was the most strongly infected, especially with M. georgiana (prevalence 100%, mean abundance 113.7). The infection parameters of the majority of parasites were lower at the Vernadsky Station than in the Admiralty Bay, especially for host–parasite relations with larval cestodes and nematodes. The presently reported study have confirmed that the south− ern range of distribution of two acanthocephalans, Aspersentis megarhynchus and Coryno− soma hamanni extends south to the area near the Argentine Islands.
