1. Using carapace measurements to determine the sex of Antarctic krill (Euphausia superba)

   Abstract:  Krill carapaces measurements have been used to reconstruct krill length frequencies in Antarctic fur seal diet. The discriminant function currently used to determine sex, and the sex-specific allometric equations for calculating total length from carapace length, were derived from South

2. Modelling growth of Antarctic krill: a new approach to describing the growth trajectory

   Abstract:  Von Bertalanffy (VB) growth models for Antarctic krill have in the past been calibrated from population-level data consisting of modal lengths obtained from a time sequence of length frequency samples. We develop an alternative approach to predicting the trajectory of length over time

3. Fishing ground selection in krill fishery: trends in its patterns across years, seasons, and nations

   Abstract:  Patterns of fishing ground selection were characterized using STATLANT and CCAMLR fine scale data. Among the 15 SSMUs within Areas 48.1, 48.2 and 48.3 including the pelagic SSMUs, only one third of them were identified as the main contributors to the total catch. A shift of operational

4. CCAMLR observer manual questionnaires: summary results of preliminary analysis during its introductory period

   Abstract:  Preliminary analysis of data from the questionnaires of krill fishery behavior in CCAMLR observer manual was undertaken. The analysis revealed possible inconsistency in definitions of the event codes among different skippers. Some suggestions were made to improve the quality of

5. On the use of scientific observers on board krill fishing vessels

   Abstract:  Wide-scale monitoring of the status of Antarctic krill resources had been previously conducted by the USSR and its results still allow scientist to prepare forecasts of changes in the ecosystem. However, at present such monitoring seems difficult. Taking into account these points,

6. Implementing plausible ecosystem models for the Southern Ocean: an ecosystem, productivity, ocean, climate (EPOC) model

   Abstract:  An ecosystem, productivity, ocean, climate (EPOC) model has been developed in the R statistical language to help explore topical issues on Antarctic marine ecosystems, including impacts of climate change, consequences of over-exploitation, conservation requirements of recovery and

7. A proposal for streamlining the work of the Scientific Committee for the Conservation of Antarctic Marine Living Resources

   Abstract:  The work of the Scientific Committee is expanding with a duplication of some functions in different working groups. There is also a need to give time to emerging issues for which there is insufficient time at present in the existing working groups, such as consideration of marine

8. Preliminary report of sound-speed contrast and density of krill measured on board RV Kaiyo Maru

   Abstract:  The target strength (TS) of Antarctic krill, Euphausia superba, is a scaling factor to convert the acoustic backscattering strength into the population density. Therefore, it is important to improve the accuracy and precision of the TS value. Since in situ and experimental TS

9. Mortality of macaroni penguins (Eudyptes chrysolophus) at Marion Island caused by avian cholera (Pasteurella multocida) in 2004/05

   Abstract:  At Marion Island, an outbreak of Avian Cholera Pasteurella multocida killed about 2 000 Macaroni Penguins Eudyptes chrysolophus at the colony at Kildalkey Bay during November 2004. Other colonies of Macaroni Penguins and other species of seabirds were not affected. In March 1993, an

10. Breeding numbers and success of Eudyptes penguins at Marion Island, and the influence of arrival of adults

    Abstract:  At Marion Island, there was considerable correlation in numbers of adults breeding at study colonies for both Macaroni Eudyptes chrysolophus and Eastern Rockhopper E. chrysocome filholi Penguins, over 26 and 22 years respectively, suggesting over-wintering conditions may influence the
