1. Plan of research program of the Ukraine in Subarea 48.2 in 2016 (second season)

   Abstract:  During March-April 2015 Ukraine began the research within statistical subarea 48.2 in accordance with the recommendations of CCAMLR-XXXIII. The certain number of the following bottom long line surveys are proposed to be conducted during March-April 2016. The research surveys will be

2. Proposal to continue participation in the second year of the joint CCAMLR research survey to collect spatially stratified longline and bathymetric data in 88.2_A and 88.2_B in 2015/16

   Abstract:  Toothfish in SSRUs 882.A–B are currently managed as part of the Ross Sea region stock, but the stock structure and fish movement patterns are uncertain and more information is required for the management across all of the region. Recognising this requirement, the Scientific Committee

3. Results of the longline survey for toothfish in the northern Ross Sea region (SSRU 88.2A) by the FV Seljevær, Norway

   Abstract:  A multi-year, multi-member research program was established to map and sample the fishable areas of SSRUs 88.2 A–B north of 66° S latitude. During the 5 th- 7 th February 2015, the Norwegian fishing vessel FV Seljevær surveyed SSMRU 88.2 A, research block 3, defined in the multi-Member

4. Investigations on tagging data in the Kerguelen Islands Patagonian toothfish fishery (division 58.5.1)

   Abstract:  In 2014, FSA-14-36r1 presented a new assessment of Patagonian toothfish in the French EEZ. A singularity in the tagging fits was observed by the working group. A lower number of recaptures in the first year compare to the second year was noted (figure1). This paper is an overview of

5. Results of the fourth CCAMLR sponsored research survey to monitor abundance of sub-adult Antarctic toothfish in the southern Ross Sea, February 2015 and further development of the time series

   Abstract:  At its 2011 meeting, the Scientific Committee agreed that a time series of relative abundance from a well-designed survey could be a useful input into the Ross Sea stock assessment model. The first three surveys were completed in February 2012, 2013, and 2014. In this paper we provide

6. 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

7. 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

8. 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

9. 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

10. 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,
