1. Supplement to the krill synoptic survey design in Area 48 (with participation of a Russian scientific research vessel)

   Abstract:  The necessity of synoptic survey covering the South Sandwich Islands that are an integral part of Area 48 is discussed. It is shown that in this case there shall be obtained for the first time for the recent twenty years the material which allows to have an idea of krill simultaneous

2. Fatty acid signature analysis from the milk of Antarctic fur seals and southern elephant seals from South Georgia: implications for diet determination

   Abstract:  Fatty acid signature analysis (FASA) makes use of specific fatty acids, as well as entire profiles, to study dietary relationships at different trophic levels. Previously, FASA has been used in marine ecosystems in which diet determination by more direct methods is difficult and

3. An examination of variance and sample size for female Antarctic fur seal trip durations

   Abstract:  This paper uses power analysis and bootstrap functions to examine the importance of sample size in detecting differences between two years of fur seal trip duration data. Female foraging trip duration for the first six trips to sea for 1997/98 (n = 30) and 1998/99 (n = 31) at Cape

4. The effect of different methodologies used in penguin diet studies at three US AMLR predator research sites: Admiralty Bay, Palmer Station and Cape Shirreff

   Abstract:  Diet studies are a key component of the CCAMLR predator monitoring program as they provide direct assessments of the prey types and amounts of import to predators, which, in turn, are hypothesized to influence variability in related parameters such as breeding success, foraging trip

6. CPUEs and body length of Antarctic krill density during the 1997/98 season in Area 48

   Abstract:  This paper summarizes the Japanese krill catch data during austral summer through winter of 1997/98 season in the Area 48. The fishing grounds were formed around the South Shetland Islands, west of the Antarctic Peninsula, and around the South Orkneys Islands from mid-December to mid-May

8. An index of per capita recruitment

   Abstract:  An index of per capita recruitment (PCR) is proposed such that Ri PCRy–1 = R1y/(1–R1y)eM where R1 is the proportion of age-1 animals sampled in year y and M is the post-recruit mortality rate. The intent of the index is to facilitate investigation of reproductive success and the factors

9. An idea to incorporate potential recruitments in the krill density model

   Abstract:  A krill density model suggested during WG-EMM at Kochi (Dy?(1-Rl)-Dy-1?e-M=0) still involved uncertainties of age 1 krill. Present document improves the model by taking the uncertainties in to account, and assuming a reasonable mortality. The model suggested that if we expect the

10. Relationship between Antarctic krill (Euphausia superba) variability and westerly fluctuations and ozone depletion in the Antarctic Peninsula area

    Abstract:  An assessment of the environmental processes influencing variability in the recruitment and density of Antarctic krill (Euphausia superba) is important, as variability in krill stocks affects the Antarctic marine ecosystem as a whole. We have assessed variability in krill recruitment and
