1. Results of the sixth Ross Sea shelf survey to monitor abundance of sub-adult Antarctic toothfish in the southern Ross Sea, January 2017

   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. In this paper we provide results of the sixth annual survey in the time series. The objectives of

2. Simulations to evaluate model performance for Antarctic toothfish stock assessment in the Amundsen Sea region

   Abstract:  The Amundsen Sea region (ASR) is currently managed under a research plan, which has shown promising results to date, with 8 interseason tags recaptured in the South area in 2016 and 12 (preliminary recaptures) in 2017. The aim of this paper is to ascertain when the Amundsen Sea region

3. Updating the 2017 stock assessment of Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea region

   Abstract:  The Antarctic toothfish stock assessment for the Ross Sea region (Subareas 88.1 and 88.2AB) will be updated in 2017. The introduction of CM 91-05 (the Ross Sea region Marine Protected Area) will require modifications to the previous method the estimation of catch splits in the

4. The Ross Sea region Marine Protected Area Research and Monitoring Plan (WG-SAM 2017)

   Abstract:  The Ross Sea region MPA Research and Monitoring Plan Workshop (WS-RMP) was held at the Palazzo Farnesina (Ministry of Foreign Affairs and International Cooperation, MAECI) in Rome from 26–28 April 2017. The purpose of the workshop was to develop a draft research and monitoring plan (RMP)

5. Research plan for the exploratory longline fishery for Dissostichus spp. in Subarea 88.3 in 2017/18

   Abstract:  The subarea 88.3 is a large area contained from 105° W to 70° W where has been closed to directed fishing following the results of a Chilean survey activities in 1998 (SC-CCAMLR-XVII/BG/7). Previous three research surveys conducted by the New Zealand and the Russian flagged vessels since

8. Estimating uncertainty in local biomass estimates of toothfish in CCAMLR in Subareas 58.4 and 48.6 research blocks

   Abstract:  This study has used bootstrap methodology to quantify the uncertainty in toothfish biomass estimates from Chapman mark-recapture and the CPUE-by-seabed area methods in Research Blocks in Subareas 58.4 and 48.6. The Chapman mark-recapture point estimates and their confidence intervals

9. Assessing data requirements for tag-based estimates of local biomass in data-poor and exploratory fisheries

   Abstract:  This study used an operating model to simulate a Dissostichus eleginoides population in Research Block 5843a_1 with a fixed exploitation rate and various tagging rate scenarios to assess the impact on the numbers of tagged fish recaptures and accuracy of tag-based estimates using the

10. An update on using the CCAMLRGIS R package to create polygon data and access data on the CCAMLR online GIS

    Abstract:  To facilitate access to spatial data for use in analyses and generating graphics (i.e. maps) in R the CCAMLRGIS R package has been upgraded to provide direct access to polygon data that can be viewed on the online GIS. This package can also be used to create polygon data that can either
