1. IN SITU MEASUREMENTS OF TILT ANGLE DISTRIBUTION AND TARGET STRENGTH IN ANTARCTIC KRILL (EUPHAUSIA SUPERBA)

   Abstract:  Knowledge of the scattering properties of Antarctic krill (Euphausia superba) is crucial for biomass estimates of the species, but in situ investigations regarding this are still very scarce. We conducted a field study in the Southern Ocean where one of the objectives was to acquire data

2. A RISK ASSESSMENT TO ADVISE ON STRATEGIES FOR SUBDIVIDING A PRECAUTIONARY CATCH LIMIT AMONG SMALL-SCALE MANAGEMENT UNITS DURING STAGE 1 OF THE STAGED DEVELOPMENT OF THE KRILL FISHERY IN SUBAREAS 48.1, 48.2, AND 48.3.

   Abstract:  We used Foosa and the reference set of parameterizations developed by Watters et al. (2008) to assess the risks and tradeoffs associated with various management strategies for subdividing the precautionary krill catch limit among SSMUs in Area 48. Our methodological approach follows

3. A PRELIMINARY BALANCED TROPHIC MODEL OF THE ECOSYSTEM OF THE ROSS SEA, ANTARCTICA, WITH EMPHASIS ON APEX PREDATORS

   Abstract:  We report on the development of a mass balanced carbon-budget trophic model of the Ross Sea as a step towards investigating ecosystem effects of the fishery for Antarctic toothfish (Dissostichus mawsoni). The model has 30 trophic groups representing all the major biota of the Ross Sea.

4. TROPHIC OVERLAP OF WEDDELL SEALS (LEPTONYCHOTES WEDDELLI) AND ANTARCTIC TOOTHFISH (DISSOSTICHUS MAWSONI) IN THE ROSS SEA, ANTARCTICA

   Abstract:  We present information to investigate the significance of Antarctic toothfish as a prey item for Weddell seals in the Ross Sea. • We summarise the life history of Weddell seals to provide an overview of their use of the Ross Sea. As consumption of prey by Weddell seals (both the amount

5. CONDITIONING SMOM USING THE AGREED CALENDAR OF OBSERVED CHANGES IN PREDATOR AND KRILL ABUNDANCE: A FURTHER STEP IN THE DEVELOPMENT OF A MANAGEMENT PROCEDURE FOR KRILL FISHERIES IN AREA 48

   Abstract:  The updated version of the Spatial Multi-species Operating Model (SMOM) of krill-predator-fishery dynamics described in an accompanying paper is conditioned using the WG-SAM set of reference observations for Area 48 (the SAM calendar). Results are presented for two implementations of

7. Relationships between oceanographic environment and distribution of krill and baleen whales in the Ross Sea and adjacent waters, Antarctica in 2004/05

   Abstract:  We have surveyed the ecological interactions between the oceanography and biological ecosystem in the Ross Sea and its adjacent waters with a joint survey the R/V Kaiyo Maru and the Japanese Whale Research Program in the 2004/05 austral summer. We compared the relationship between the

8. Relationship between distribution of Antarctic krill (Euphausia superba) and environmental index MTEM-200 in the Antarctic Ocean throughout the year

   Abstract:  Antarctic krill (Euphausia superba) is the key species of the Antarctic marine ecosystem and human fishing resources. Essentially, relationships between krill distribution and oceanographic conditions have been an age-old recurrent problem and many papers have been published on the

9. Short note: Time series of Drake Passage Oscillation Index (DPOI) during 1952-2008 and its possible influence on environmental variability

   Abstract:  An assessment of the environmental processes influencing variability in the recruitment and density of Antarctic krill (Euphausia superba DANA) is important as variability in krill stocks affects the Antarctic marine ecosystem as a whole. Naganobu et al. (1999) had assessed variability

10. Systematic Coverage’ by scientific observers on Krill Fishing Vessels

    Abstract:  A work plan to establish an observer scheme for krill fishery was agreed at the previous Scientific Committee and the Commission. The first step was to consider ‘systematic coverage’ of the observers. In this document, Japan proposes a framework for scientific observer system for krill
