  1. On acceptable scattering of longlines geo-referencing in the toothfish fishery in the CAMLR Convention Area

    Abstract:  The issues of longlines geo-referencing during the exploratory fisheries of the ... toothfish in the Convention Area are discussed. Cases of differences in the coordinates of settings and ... haulings are considered. The estimation of the maximum possible variation of the coordinates in the depths ... range of 550-3000 m was performed. It is shown that the differences of coordinates of settings and ...

  2. An alternative method for estimating the level of illegal fishing using simulated scaling methods on detected effort

    this new method are similar to those of the Agnew and Kirkwood (2005) method, and this suggests that ... the current method is adequate under circumstances of low evasion and when good knowledge exists that ... zero observations reflect zero illegal fishing. The new method performs better in the case of zero ... detections and can potentially better handle the evasion of detection by illegal activity. Both the new and ...

  3. Food consumption estimates of southern elephant seal females during their post-breeding aquatic phase at South Shetland Islands

    , King George Island (25 de Mayo). During lactation females spent a mean of 6021±1365 Mj, which resulted ... in a loss of 35% of the initial mass, comprising 63% of initial body fat and 20% of initial body ... to recover an average of 55% of the mass, including 46% of the fat, 71% of the protein and 47% of the ... gained while at sea. However, protein loss expressed in absolute terms or as a proportion of that present ...

  4. An alternative method for estimating the level of illegal fishing using simulated scaling methods on detected effort

    is adequate under circumstances of low evasion and for when good knowledge exists that zero ... observations reflects zero illegal fishing. The new method performs better in the case of zero detections and ... can potentially better handle the evasion of detection by illegal activity. Both the new and the ... current method suffer from the type of observations method used, which directly affects the system. This ...

  5. Preliminary assessment of Dissostichus eleginoides on the Heard Island Plateau (Division 58.5.2) based on a survey in April–May 2003

    Abstract:  A preliminary assessment of yield of Patagonian Toothfish, Dissostichus eleginoides ... result of a randomly stratified trawl survey completed between 16 April and 10 May 2003. The 2003 ... estimate of abundance of recruits indicates a continuation of a period relatively low recruitment since ... preliminary estimate of sustainable long-term yield assessed using the standard method. The preliminary ...
