  1. New Zealand’s exploratory fishery for toothfish within the SPRFMO Convention Area: update and future directions

    Abstract:  The 2-year programme of exploratory fishing provided for by SPRFMO CMM 4.14 has been ... successfully completed and new and important biological information has been collected on toothfish outside the ... CCAMLR convention area. The key findings are that only Antarctic toothfish, Dissostichus mawsoni, were ... surveys provide information on the life history of Antarctic toothfish that is consistent with the current ...

  2. Spatial and temporal operation of the Scotia Sea ecosystem: a review of large-scale links in a krill centred food web

    Abstract:  The Scotia Sea ecosystem is a major component of the circumpolar Southern Ocean system ... , where productivity and predator demand for prey are high. The eastward-flowing Antarctic Circumpolar ... Current (ACC) and waters from the Weddell–Scotia Confluence dominate the physics of the Scotia Sea ... , manifest by the changing irradiance and sea ice cover, which leads to shorter summers in the south. Summer ...

  3. Shags in Antarctica: their feeding behaviour and ecological role in the marine food web.

    as regulators of populations of its main fish prey species that have a marked site fidelity. The ... Abstract:  Feeding behaviour, ecological role in the marine food web and population trend of the ... Antarctic Shag Phalacrocorax bransfieldensis and the South Georgia Shag P. georgianus in Antarctica are ... analysed. The diving depths and duration registered in these shags are the deepest and longest among all ...

  4. Spatial distribution of predator/prey interactions in the Scotia Sea: implications for measuring predator/fisheries overlap

    Abstract:  The measurement of spatial overlap between predators and fisheries exploiting a common ... prey source is dependent upon the measurement scale used and the use of inappropriate scales may ... provide misleading results. Previous assessments of the level of overlap between predators and fisheries ... for Antarctic krill Euphausia superba in the South Shetland Islands have used different measurement ...

  5. Reconciling theoretical versus empirical target strengths of krill; effects of phase variability on the distorted wave Born approximation

    Abstract:  A model was recently proposed to predict the target strengths (TS) of Antarctic krill ... ]. Based on the distorted wave Born approximation (DWBA), the model depends upon the coherent summation of ... broadside incidence (?? 90°), but large discrepancies were observed at other angles away from the main lobe ... . As the side-lobe measurements were both higher than the model predictions and above the noise floor ...

  6. The fishery for Champsocephalus gunnari and its biology at Heard Island (Division 58.5.2)

    Abstract:  Commercial trawl fisheries in the modern era started within the Heard Island EEZ in ... 1997. This paper summarises the fishing activities to date and collates the information on the biology ... of the species gathered from the fishery and from a series of fishery-independent surveys conducted ... between 1990 and 2000. Icefish abundance varies widely between years and the fishery is dependent on ...

  7. ON THE STUDY OF FECUNDITY AND EGGS SIZE OF ANTARCTIC TOOTHFISH DISSOSTICHUS MAWSONI NORMAN 1937

    Abstract:  The results of the microscopic analyses of the Antarctic toothfish (Dissostichus ... mawsoni) fecundity and eggs size, caught in December-March the Pacific and Indian Ocean area of the ... Antarctica are presented. We analyzed the main reproductive characteristics which determinate the individual ... fecundity of the Antarctic toothfish: individual absolute fecundity by the largest oocytes, share of largest ...

  8. Changes in population size of large Procellariiformes breeding in the French sub-Antarctic islands: potential influence of southern fisheries and particularly long lining

    Abstract:  Studies carried out over the past three decades in the French austral territories ... indicate that these declines are mainly the result of increased adult mortality. This high rate of ... mortality has been suspected to be the result of mortality incurred in long-line fisheries. Satellite ... outside the breeding season these populations are in contact with long-line fisheries, mainly the pelagic ...
