Abstract The aim of this study was to assess the anisakid nematode distribution pattern in the fish collected from the South Shetland Islands. A total of 32 fish species were examined for the presence of nematodes in 1978,1979,1981 and 2007/2008. The fish were caught off the South Shetland Islands (Elephant Island, Shishkov Island and in Admiralty Bay - King George Island). Three genera of L3 larval nematodes were identified: Anisakis sp., Contra-caecum spp. and Pseudoterranova decipiens. The infection level was higher on the shelf around the islands than in Admiralty Bay. This is explained by a higher abundance of the final hosts in the region. A comparison of the infection data from 1978/79 and 2007/2008 with data from 1994/96 (Palm et al. 1998, 2007) was done. The parameters of infection of Notothenia coriiceps and Lepidonotothen nudifrons by Pseudoterranova decipiens were decreasing within the 30 years period.
