1. Models of Antarctic marine ecosystems in support of CCAMLR and IWC: background

   Abstract:  Ecosystem models are being developed to explore a range of issues globally. This paper is currently in draft form open to comment and is being developed to provide an introduction to the CCAMLR-IWC Workshop to review input data for Antarctic marine ecosystem models. It summarises

4. PROPOSED SMALL-SCALE MANAGEMENT UNITS FOR THE KRILL FISHERY IN SUBAREA 48.4 AND AROUND THE SOUTH SANDWICH ISLANDS

   Abstract:  Relatively little ecological information is available for the South Sandwich Islands, so the diversity of information available to determine potential SSMU boundaries is limited. Nevertheless, a suggested SSMU is proposed, based on the foraging distance of the most abundant land-based

5. ALLOCATING THE PRECAUTIONARY CATCH LIMIT FOR KRILL AMONGST THE SMALL-SCALE MANAGEMENT UNITS IN AREA 48: THE IMPLICATIONS OF DATA UNCERTAINTIES

   Abstract:  Over the past few years WG-EMM has been developing a management procedure for the krill fishery in Statistical Area 48. This procedure will involve, inter alia, subdivision of the precautionary catch limit among a set of small-scale management units. So far the Working Group has

6. DEVELOPING FOUR PLAUSIBLE PARAMETERISATIONS OF FOOSA (A SO-CALLED REFERENCE SET OF PARAMETERISATIONS) BY CONDITIONING THE MODEL ON A CALENDAR OF EVENTS THAT DESCRIBES CHANGES IN THE ABUNDANCES OF KRILL AND THEIR PREDATORS IN THE SCOTIA SEA

   Abstract:  We tuned four parameterizations of Foosa to provide predictions that are consistent with the agreed calendar, as specified by the WG-SAM, that describes changes in the abundances of krill and their predators in the Scotia Sea. First, we compiled a set of base parameterizations from

7. THE ANTARCTIC KRILL AND ECOSYSTEM SURVEY WITH R/V “G. O. SARS” IN 2008

   Abstract:  This report describes the multipurpose AKES survey (Antarctic Krill and Ecosystem Studies) carried out with R/V G. O. Sars, 4.01-27.03.08, including some selected results. The main purposes for the AKES project were to • evaluate the links between the krill resources and distribution in

8. 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

9. 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

10. 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.
