1. Catch Uncertainty in Krill Fisheries

   Abstract:  Catch uncertainty is a component of uncertainty that is not routinely considered by CCAMLR. However, given the currently reported variability in conversion factors for krill, a nominal reported catch of 600 000t could actually represent a catch in ‘green weight’ of 2.5 million tonnes.

2. PROGRESS TOWARDS EXPERT GROUP MANUSCRIPTS FOR THE CCAMLR-IWC WORKSHOP TO REVIEW INPUT DATA FOR ANTARCTIC MARINE ECOSYSTEM MODELS: UPDATE ON PROGRESS 2008

   Abstract:  This document summarises progress by expert groups towards having manuscripts ready for the CCAMLR-IWC Workshop to review input data for Antarctic marine ecosystem models: update on progress 2008. Data collation is progressing well for all groups, except for flying birds. Draft

3. MULTIPLE TIME SCALES OF VARIABILITY IN THE KRILL POPULATION AT SOUTH GEORGIA

   Abstract:  The South Georgia region supports a high biomass of krill that is the subject to high inter-annual variability. The lack of a self-sustaining krill population at South Georgia means that understanding the mechanism underlying these observed population characteristics is essential to a

4. Short note: By-catch of fishes caught by the krill fishing vessel Niitaka Maru in the South Georgia area (August 2007)

   Abstract:  Scientific observation on the species composition and abundance of fishes incidentally caught during Antarctic krill (Euphausia superba DANA) fisheries by F/V Niitaka Maru (5200t) were made from 6 August to 30 August to the north of South Georgia Is. Among 87 net hauls quantitatively

6. CLIMATICALLY DRIVEN FLUCTUATIONS IN SOUTHERN OCEAN ECOSYSTEMS

   Abstract:  Determining how climate fluctuations affect ocean ecosystems requires an understanding of how biological and physical processes interact across a wide range of scales. Here we examine the role of physical and biological processes in generating fluctuations in the ecosystem around South

7. 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

8. 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

9. 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

10. 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
