  2. Preliminary assessment of the South Georgia ray populations

    Abstract:  We modelled the ray population at South Georgia using a surplus production model ... implemented in a Bayesian framework. Catch and CPUE data were reconstructed for the time series 1985 – 2006 ... from a variety of sources, and included the consideration that since 2004 the practice of cutting rays ... capacity but not with respect to r, the intrinsic rate of growth of the ray population. We chose a ...

  4. An updated descriptive analysis of the toothfish (Dissostichus spp.) tagging programme in Subareas 88.1 and 88.2 up to 2005/06

    Abstract:  A descriptive analysis of the toothfish tagging programme carried out in Subareas 88.1 ... still only available for about half of the non-New Zealand vessels for 2003-04. A reported total of 10 ... . About 17% of the recaptures could not be matched to a release observation, mainly because of missing ... fish in the Ross Sea was very close to the size composition of the catch. Author(s):  A. Dunn and S.M ...

  5. Approaches to monitoring and assessing the abundance of rattails (Macrourus spp.) and skates in the Ross Sea

    Abstract:  This report presents results from a desktop study to consider approaches to monitoring ... , and acoustic surveys. We recommend that a random bottom trawl survey would be the best approach ... range 600–1500 m to obtain a precise estimate of bycatch abundance in the area of highest densities ...

  6. Population and survival trends of wandering albatrosses (Diomedea exulans) breeding on Macquarie Island

    effort and survival varied markedly with breeding numbers declining from a peak in 1964 to near ... extinction levels in the mid 1980’s. Underlying this decline was a significant decrease in juvenile survival ... and, to a lesser extent, adult survival. These survival changes were coincident with changes in ... . Author(s):  A.
