A large (1.80 metres in length and weighing 70 kg) Patagonian toothfish (Dissostichtus eleginoides Smitt, 1898) has been caught in the northwest Atlantic, representing the first Northern Hemisphere record of the diverse, abundant and mainly Antarctic suborder Notothenioidei. This extraordinary catch indicates that large, cold-temperate fishes may occasionally migrate from sub-Antarctic to sub-Arctic waters by using deep, cold water, supporting a widely accepted but unproven proposal that the… 
Distribution and reproduction of the Patagonian toothfish Dissostichus eleginoides Smitt around the Falkland Islands
The migratory life style of the south-west Atlantic population of the Patagonian toothfish is probably very different from that of other populations, which tend to be resident as they are inclined to inhabit the waters around oceanic islands and sea mounts with narrow shelf areas.
Transoceanic Migrations of Fishlike Animals and Fish: Norm or Exclusion?
Abstract The paper presents an overview of data based on the analysis of published information concerning the transoceanic migrations of lampreys (Petromyzontidae), sharks (Selachii), and
Biological implications of low condition factor “axe handle” specimens of the Antarctic toothfish, Dissostichus mawsoni, from the Ross Sea
It is suggested that migration, a life history trait of the phyletically basal notothenioid clades Pseudaphritis and Eleginops, persists in D. mawsoni and the spawning migration from the southern shelf to ridges and seamounts in the north may reflect fidelity to historic spawning grounds.
Systematics of Polar Fishes
Genetic structure of Patagonian toothfish populations from otolith DNA
Methods for extracting toothfish DNA from otoliths that are available in large numbers from collections held at several research institutes are developed, demonstrating the usefulness of otolith DNA as a means of increasing sample sizes for population genetics research of fish.
Genetic structure of Patagonian toothfish (Dissostichus eleginoides) populations on the Patagonian Shelf and Atlantic and western Indian Ocean Sectors of the Southern Ocean
The genetic structure of Patagonian toothfish populations in the Atlantic and western Indian Ocean Sectors of the Southern Ocean were analysed using partial sequences of the mitochondrial 12S rRNA gene and seven microsatellite loci to identify genetically distinct populations.
Otolith chemistry indicates population structuring by the Antarctic Circumpolar Current
The results suggest that toothfish populations are structured by their physical environment; population abundance and persistence may rely on a restricted number of breeding members with access to spawning grounds, whereas fisheries may rely substantially on nonbreeding vagrants trans- ported from fishing areas upstream.
A checklist of the fish fauna of Greenland waters
The opportunity of the International Polar Year 2007–08 is presented to present an updated check-list of the fishes of Greenland and discuss whether the growing diversity can be explained by global warming.


Origin of the antitropical distribution pattern in marine mussels (Mytilus spp.): routes and timing of transequatorial migration
Data indicate that southern hemisphere mussels arose from a migration event from the northern hemisphere during the Pleistocene via an Atlantic route, suggesting a second, more recent migration to the southern hemisphere.
Possible pathways of Paraliparis (Pisces: Liparididae) and some other North Pacific secondarily deep-sea fishes into North Atlantic and Arctic depths
It is suggested that shallow water liparid fishes penetrated the North Atlantic via the Bering Strait and the Arctic seas during the pre-glacial (Pliocene) transgression.
