      1     Introduction

      The Scientific Committee established WG-SAM during CCAMLR-XXV (SC-CAMLR-XXV, paragraph 13.12), with a directed emphasis on developing, refining, and evaluating quantitative approaches for all Antarctic marine living resources managed by CCAMLR. WG-SAM serves as a flexible technical group to address quantitative issues relevant to WG-FSA, WG-EMM, and ad hoc WG-IMAF (SC-CAMLR-XXV, paragraphs 13.4 to 13.8). WG-SAM is to provide advice necessary for the work of these working groups and the Scientific Committee.

      Working papers submitted to WG-SAM, along with presentations and analyses conducted during the meeting, will form the basis for discussion and advice.

      The terms of reference for the Working Group on Statistics, Assessments and Modelling (WG-SAM) are:

      To provide advice to the Scientific Committee and its working groups on:

      (i) quantitative assessment methods, statistical procedures, and modelling approaches for the conservation of Antarctic marine living resources; and

      (ii) the implementation and data requirements of such methods, procedures and approaches.

      1.1     Opening of the meeting

      Welcome to participants and overview of facilities, Secretariat’s offices, computer support, Internet access and extracurricular activities.

      1.2     Adoption of the agenda and organisation of the meeting
      2     Evaluation of research plans from members notifying to fish in new and exploratory fisheries in Subareas 48.6 and 58.4

      A requirement to submit research plans in notifications for new and exploratory fisheries in areas other than Subareas 88.1 and 88.2 was adopted by the Commission at its 2011 meeting (CCAMLR, 2011). WG-SAM will review these research plans to determine whether they meet the requirements for CCAMLR sponsored research as laid out in SC-CAMLR-XXX, Annex 5, paragraphs 2.25 and 2.26. The review will use the format provided in Table 6 of  WG-SAM-2012.

      3     Review of scientific research proposals for other areas (e.g. closed areas, areas with zero catch limits, Subareas 88.1 and 88.2)

      Scientific research carried out during the 2012/2013 season will be reviewed and proposals for further research on toothfish stocks in these areas evaluated. WG-SAM will review any new research proposals to determine whether they meet the requirements for CCAMLR sponsored research using the format provided in Table 6 of WG-SAM-2012.

      4     Methods for assessing finfish stocks in established fisheries, notably Dissostichus spp.

      Methods for assessing stock status and yield have been agreed and are in use for Dissostichus spp., Champsocephalus gunnari and Euphausia superba for the main areas in which these species are fished. Proposals to modify these methods or to consider alternative methods will be reviewed under this item.

      4.2     Toothfish biology

      WG-SAM provides advice to each of the working groups and to the Scientific Committee on statistics, assessments and modelling. Specific advice that has been requested will be summarised in this agenda item following general discussion in other agenda items. Advice will also be given to the Scientific Committee on the priorities apparent during the meeting for the development and refinement of quantitative methods.

      7     Adoption of report and close of meeting

      As is usual practice in meetings of the Scientific Committee and its working groups, rapporteurs will draft sections of the report according to general guidelines for its production. The Secretariat is responsible for formatting, editing and circulation of the report. Any proposed changes to the report prior to report adoption need to be arranged through the rapporteurs, who will then provide the appropriate changes to the Secretariat. Adoption of the report will be conducted interactively using a video projector and support from the Secretariat.

      Discussion will conclude at the end of the day on Wednesday, allowing for Thursday and Friday morning for report preparation and reading. Report adoption will be on Friday afternoon.
