  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

    Meeting Document : WG-FSA-03/74 : Autor(es): K. Reid, S. Hill and T. Diniz (United Kingdom)

  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

  3. Estimating the age of large numbers of Dissostichus eleginoides caught off Kerguelen

    Author(s):  J. Ashford (USA), G. Duhamel (France), C. Jones and S. Bobko (USA) Title:  Estimating the age of large numbers of Dissostichus eleginoides caught off Kerguelen Approval:  Approved

    Meeting Document : WG-FSA-03/87 : Autor(es): J. Ashford (USA), G. Duhamel (France), C. Jones and S. Bobko (USA)

  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,

    Meeting Document : WG-FSA-03/84 : Autor(es): J.R. Ashford, C.M. Jones, E. Hofmann (USA), I. Everson (United Kingdom) and G. Duhamel (France)

  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

    Meeting Document : WG-FSA-03/91 : Autor(es): B.J. Sullivan, T.A. Reid, L. Bugoni and A.D. Black (United Kingdom)

  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

    Meeting Document : WG-FSA-03/92 : Autor(es): T.A. Reid and B.J. Sullivan (United Kingdom)

  10. United States research under way on seabirds vulnerable to fisheries interactions

    Author(s):  Delegation of the USA Title:  United States research under way on seabirds vulnerable to fisheries interactions Approval:  Approved

    Meeting Document : WG-FSA-03/93 : Autor(es): Delegation of the USA
