1. Proposal to continue the time series of research surveys to monitor abundance of Antarctic toothfish in the southern Ross Sea, 2016–2017

   Abstract:  A research proposal to continue the southern Ross Sea sub-adult toothfish survey for the next two years, 2016–2017, is presented. The survey will continue to focus primarily on estimating the relative abundance of sub-adult (<110 cm TL) toothfish in the core strata (A, B, C) in SSRUs

2. Results of the longline survey for toothfish in the northern Ross Sea region (Subarea 88.2 SSRUs A–B) by the FV Janas, New Zealand

   Abstract:  New Zealand FV Janas conducted research in two research blocks (882A_5 and 882B_4) as part of a multi-year and multi-member research plan using standardised longline gear to sample toothfish populations in the northern areas (60°‑ 66° S) of Subarea 88.2 SSRUs A–B. Sampling strategy and

3. Proposal for a winter longline survey of Antarctic toothfish in Subarea 88.1 SSRUs B–C in 2016

   Abstract:  We propose to conduct a scientific survey during the austral winter in the northern Ross Sea region to investigate spawning dynamics of Antarctic toothfish, as requested by the Scientific Committee in 2013. The longline survey is designed to cover key gaps in the knowledge of the life

4. Progress in the evaluation of management strategies for the Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea region

   Abstract:  Management Strategy Evaluation (MSE) has been acknowledged as the best practice to take account of uncertainties in the assessment of stocks and as a method to ensure robust management approaches. The Scientific Committee of CCAMLR has recommended MSE be used to determine the extent to

5. Potential modelling structures for a two-area stock assessment model for Antarctic toothfish (Dissostichus mawsoni) in the Amundsen Sea Region

   Abstract:  Two-area population models for Antarctic toothfish in the Amundsen Sea Region were developed further as current single area models did not fully explain the patterns in the observed data on tag recaptures and age composition. Although the hypothesised stock structure spans SSRUs 88.2C–H,

6. Progress report for the third year of the research fishery for Dissostichus spp. in Subarea 48.6 being jointly undertaken by Japan and South Africa: 2013–2015.

   Abstract:  A multi-year research plan as outlined in CM 41-04 (2012, 2013 & 2014) was initiated Statistical Subarea 48.6 by Japan and South Africa during the 2012/13 fishing season. Two vessels participated in the research project in each of the three fishing seasons and the progress achieved

7. Proposal to reposition the boundary between CCAMLR statistical Subareas 58.6 and 58.7

   Abstract:  Subareas 58.6 and 58.7 are closed to fishing outside of the Exclusive Economic Zones (EEZs) around the Crozet (France) and Prince Edward (South Africa) Archipelagos. The current boundary between Subareas 58.6 and 58.7 bisects the South African EEZ around the Prince Edward Islands. Thus

8. Update on the redevelopment of the CCAMLR database

   Abstract:  The Secretariat has embarked on a major overhaul of CCAMLR data holdings and associated IT and data infrastructure. This work, which begun in 2013, includes developing an Enterprise Data Model, redeveloping the CCAMLR database, improving data quality assurance, and modernising the data

9. Marine ecosystem acoustics (MEA): quantifying processes in the sea at the spatio-temporal scales on which they occur

   Abstract:  Antarctic ecosystems are dynamic and characterized by physically forced variability caused e.g. by fronts, eddies and ice. This creates a challenging dynamics for scientific sampling and monitoring. Realistic understanding of what can and cannot be achieved with the available sampling

10. 2015-16 Research plan in Division 58.4.4 for Dissostichus spp.

    Abstract:  Regarding the low levels of stocks of Dissostichus spp. and the high levels of IUU fishing, CCAMLR decided to close the fishery in 2002 in division 58.4.4. Since 2008 only one vessel, Shinsei maru No. 3, had conducted research fishing in accordance with a research plan submitted under CM
