3. Further calculations of the effects of krill fishing on predators

   Abstract:  Earlier initial modelling attempts by the authors are extended to consider the situation where predator survival rates depend on other factors in addition to krill biomass. This is achieved by making the survival rates depend instead on krill "availability", where there is a

4. Influence of bait quality on seabird mortality and economic losses in longline fishing: an experimental approach

5. Orientation of Antarctic krill in an aquarium

   Abstract:  Acoustic methods appear to be the best way to estimate Antarctic krill abundance directly. Information on body orientation, however, is needed to obtain reliable krill acoustic target strength (TS) values, since TS varies with body orientation. Krill body orientation was measured in an

7. Analisis de los censos de Arctocephalus gazella efectuados en el sitio de especial interes cientifico no. 32, Isla Livingston, Antarctica

   Abstract:  According to the suggestion made by the Working Group at the CEMP-CCAMLR Meeting held in Viña del Mar (Chile) in August 1992, the information about four complete censuses on the Antarctic fur seal, Arctocephalus gazella, carried out on Cape Shirreff and San Telmo Island, has been

8. Characteristics of oceanic structure in the waters around the South Shetland Islands of the Antarctic ocean between December 1990 and February 1991: outstanding coastal upwelling?

   Abstract:  The sixth Antarctic survey cruise of R/V Kaiyo Maru was carried out in waters around the Shouth Shetland Islands. where are known as the fishing grounds of krill, during the 1990-91 austral summer. In order to investigate seasonal changes in oceanic structure. two observations were put

9. New Zealand Antarctic research programme

   Abstract:  Since parameters of penguin populations may provide good indices of the abundance of the key prey species (krill) and thus the state of the Antarctic marine ecosystem, aerial reconnaissance and photography are used in the Ross Sea sector of Antarctica to determine where Adelie penguins

10. A simple approach for calculating the potential yield of krill from biomass survey results

    Abstract:  Estimates are calculated for the parameter λ in the yield equation Y = λ M B0 for a kri11 fishery in which both the fishery and kri11 growth are seasonal. The criterion used for the calculations is that the probability that the kri11 spawning biomass drops below 20% of its average pre
