Abstract

The parasite faunas of the Patagonian toothfish Dissostichus eleginoides from six locations around the Southern Ocean were studied and compared. Thirty-two parasite taxa were found. Ten parasite species are reported from D. eleginoides for the first time and some other previously reported species were new locality records. Sample size at Shag Rocks was sufficient to examine the effect of intrinsic host factors, including sex and length, on the parasite fauna and these results are discussed here. Some parasite species were found only in certain areas. Sørensen’s similarity index indicated that the parasite faunas at Heard, Maquarie and Prince Edward Islands were the most similar, while those from the Ross Sea was the most dissimilar. There may be a gradual decrease in parasite diversity the further east the samples were collected around the Southern Ocean.

Acknowledgements

We thank the Government of South Georgia and the South Sandwich Islands, British Antarctic Survey and the Marine Resources Assessment Group for providing samples from Shag Rock and South Georgia. We are also indebted to Dr. Dick Williams of the Australian Antarctic Division for providing samples from off Heard and Macquarie Islands and to Dr. Peter Smith of NIWA for providing samples from the Ross Sea. We thank Martin Purvis and Linda Staverees of Marine and Coastal Management, Cape Town for providing samples from Prince Edward Island and for providing laboratory space. The Shackleton Scholarship fund provided funds for a flight to Cape Town, for PB for which we are grateful. Consolidated Fisheries Ltd was the driving force in the initial stages of this project. We are grateful to the Director of Fisheries (Falkland Islands Government), John Barton, for supporting this work and to Professor Chris Secombes for providing laboratory facilities at the School of Biological Sciences, University of Aberdeen. We also thank Dr. Les Chappell for his help in Aberdeen. Finally, we thank the three anonymous referees that helped to improve the manuscript.
