1. Comparison of two methods to assess fish losses due to depredation by killer whales and sperm whales on demersal longline

   Abstract:  Depredation is a human-wildlife conflict over resource which often includes a combination of socio-economical, ecological and conservation issues. However, estimating the amount of depredated resource can be especially challenging when depredation occurs on fish in the marine environment

2. Possible options for the future management of the Antarctic krill fishery in Subarea 48.2

   Abstract:  During 2013, WG-EMM agreed to form two inter-sessional task groups to progress work that might facilitate the development of new management procedures for the krill fishery in Area 48. In 2014, the state of ecological knowledge for Subarea 48.2 was reviewed, and it was suggested that the

3. Revised research longline fishing proposal for Dissostichus spp. in Subarea 48.2

   Abstract:  Following advice from WG-SAM-15, a revised version of the reserach proposal for toothfish in Subarea 48.2 is presented (WG-SAM-15/53).   Author(s):  Delegation of Chile Title:  Revised research longline fishing proposal for Dissostichus spp. in Subarea 48.2 Approval:  Approved

4. An initial examination of using CPUE as a fishery performance index for the krill fishery

   Abstract:  Early analyses of CPUE in the krill fishery concluded that it was not a useful index of krill abundance. However, understanding the factors effecting the operation of the krill fishery and the extent to which these reflect changes in krill abundance are key elements of developing

5. A bioenergetics model for estimating prey consumption by an Adélie penguin population in east Antarctica

   Abstract:  We developed a bioenergetics model to estimate prey consumption by the Adelie penguin. The model predicts prey consumption throughout the breeding season and incorporates uncertainty in model parameters using Monte Carlo simulation. The model was parametised with data obtained from the

6. Update of analysis on sea-ice concentration of southern part of 48.6 and 58.4.2 for the new research block on expected spawning ground of TOA

   Abstract:  Following WG-SAM-16/42 Rev. 1, we updated the analysis on the sea-ice concentration of the period (2002-2017 until April) for 48.6_4 and 48.6_5. In addition, we also analyze the ice concentration of 58.4.2 to examine accessibility there for fishing vessels as candidate for a new research

7. Revised research plan for the 2017/18 exploratory longline fishery of D. mawsoni in Subarea 48.6 by South Africa and Japan

   Abstract:  South Africa and Japan revised the next season’s (2017/18) research plan in Subarea 48.6 using the latest CCAMLR C2 and Observer data, following the recommendations and notification from WG-SAM meeting in 2017 (e.g., WG-SAM-17 report, paragraph 4.4, 4.10, and 4.18, 2017) and data

8. The vision for a Southern Ocean Observing System

   Abstract:  The Southern Ocean is fundamentally important to the Earth system, influencing global climate, biogeochemical and ecological cycles. Limited observations suggest the Southern Ocean is changing, yet chronic under-sampling makes the causes and consequences of such changes difficult to

9. Consumption estimates for male Antarctic fur seals at the South Orkney Islands during the post mating migration

   Abstract:  The estimates of fur seal consumption of krill in subareas 48.1 to 48.3 which have been used in ecosystem modelling and CCAMLR’s risk assessment approach, are based on the distribution of fur seal breeding populations. Fur seal breeding colonies south of 60 o have remained relatively

10. Methodological aspects of the International Synoptic Krill Survey in Area 48, 2019

    Abstract:  The effect of differences in the methodology used for the CCAMLR 2000 krill acoustic survey and the 2019 synoptic survey were considered. These were 1) the effect of acoustic surveying at night, 2) differing trawl selectivity between the vessels that participated in the survey, and 3)
