1. Mackerel icefish Champsocephalus gunnari in the diet of upper trophic level predators at South Georgia: implications for fisheries management

   Abstract:  Mackerel Icefish Champsocephalus gunnari Lönnberg is an important component of the ecosystem at South Georgia where its diet is dominated by Antarctic Krill Euphausia superba, it is an important prey species for a number of upper trophic level predators, and is the target of commercial

2. Preliminary results from a study examining spatial structure and connectivity in Patagonian toothfish (Dissostichus eleginoides) in the South Atlantic section of the Southern Ocean

   Abstract:  Using the High Resolution laser-ICPMS at Old Dominion University, we sampled the edge of otoliths from Patagonian toothfish (Dissostichus eleginoides), and examined whether the elemental signatures could discriminate between geographic locations along the Scotia Arc and along the eastern

4. Can trace element signatures in the otoliths of Dissostichus eleginoides record capture size?

   Abstract:  The elemental structure of growth increments in the otoliths of fish reflects the composition of water passing across the gills: as a result, elemental signatures can potentially be used to reconstruct the environmental history experienced by fish. To test whether the otolith elemental

5. Monitoring of relative abundance of fjord Notothenia rossii, Gobionotothen gibberifrons and Notothenia coriiceps at Potter Cove, South Shetland Islands, in years 2000 to 2003

   Abstract:  The monitoring program of demersal fish at inshore sites of the South Shetland Islands has continued in Potter Cove from 2000 to 2003, covering a continuous sampling period of twenty years and in Harmony Cove, Nelson Island, in the austral summers from 2001 to 2003. The decline in

6. Is population structure of Patagonian toothfish (Dissostichus eleginoides) determined by the Antarctic Circumpolar Current?

   Abstract:  Water transported by the Antarctic Circumpolar Current (ACC) in the Southern Ocean may provide opportunities for Patagonian toothfish (Dissostichus eleginoides) to move downstream between island groups with little energetic cost, and may constrain movement in other directions,

7. Sampling toothfish from longlines with unequal probabilities

   Abstract:  To obtain a representative sample of the catch taken by toothfish longliners, CCAMLR observers are recommended to sample a quota of the first 30 fish that are caught during a sampling session. Since toothfish are often aggregated on a line, this means that fish within aggregations are

8. Seabird mortality and the Falkland Islands trawling fleet

   Abstract:  Specifically tasked seabird observers recorded seabird interactions during shooting, trawling and hauling operations for 157 days onboard finfish trawlers in the Falkland Islands in 2002/03. It is estimated that >1,500 seabirds, predominantly black-browed albatross (Thalassarche

9. Longliners, black-browed albatross mortality and bait scavenging in the Falkland Islands: what is the relationship?

   Abstract:  The rate of foraging attempts by black–browed albatross on baited hooks during Spanish-system (demersal) longline setting operations, and a range of environmental and operational variables were used to investigate the relationship between their foraging behaviour and their mortality
