1. Joint SC-CAMLR and SC-IWC Workshop, its format and draft Terms of Reference

   Abstract:  A proposal for a Joint SC-CCAMLR IWC Workshop to develop multi-species models of the Antarctic marine ecosystem was proposed at the SC-CCAMLR 2014, and a steering group for the Workshop was formed. WG-EMM 2015 agreed on the benefit of dividing the workshop into two; the first to review

2. Results of the 2015 multi-Member longline survey for toothfish in the northern Ross Sea region (Subarea 88.2 SSRUs A–B) and proposal for 2016 operations

   Abstract:  The first year of a two-year and multi-member research survey using standardised longline gear to sample toothfish populations was carried out in the northern areas (60°‑ 66° S) of SSRUs 88.2A–B. The sampling strategy and data collection adhered to standards set in CM 41-10 (2014). A

3. Have Antarctic toothfish returned to McMurdo Sound?

   Abstract:  A dramatic reduction in catch rates of Antarctic toothfish in McMurdo Sound, Antarctica, has led to conclusions that the commercial bottom longline fishery for toothfish in the Ross Sea has drastically altered the toothfish population with cascading effects on the McMurdo Sound ecosystem

4. A proposal for a standardised survey for Antarctic toothfish in McMurdo Sound

   Abstract:  We propose to implement a random, depth-stratified vertical longline survey conducted through the annual sea ice in McMurdo Sound to monitor the age composition, diet, maturity, and local abundance of Antarctic toothfish. A pilot season was carried out in 2014, where sampling gear and

5. Revised proposal to continue the time series of research surveys to monitor abundance of Antarctic toothfish in the southern Ross Sea, 2016 and 2017

   Abstract:  A research proposal to continue the southern Ross Sea sub-adult toothfish survey for the next two years, 2016 and 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

6. Assessment models for Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea region for the years 1997–98 to 2014–15

   Abstract:  We provide an update of the Bayesian sex and age structured population stock assessment for Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea region (Subareas 88.1 and SSRUs 88.2A–B), using catch, catch-at-age, and tag-recapture data from 1997–98 to 2014–15 and including the

7. Diagnostic plots of stock assessment models for Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea region for the years 1997–98 to 2014–15

   Abstract:  We provide extensive diagnostic plots for models R1 and R2 for Antarctic toothfish in the Ross Sea as recommended by SAM-2015 (2015). The stock assessment rationale and models as well as their main diagnostics are described in Mormede et al. (2015). The CASAL files for models R1 and R2

8. Draft updated data collection plan for the Ross Sea toothfish fishery

   Abstract:  Data are collected for use in scientific research, the results of which are used to inform management decisions made to achieve specific goals. Any data collection plan should be drawn from the goals the management wishes to achieve. The long-term goals of the Ross Sea fishery based on

9. Predation release of Antarctic silverfish in the Ross Sea: how sensitive is the conclusion to uncertainties in the diet of Antarctic toothfish over the shelf?

   Abstract:  Between 2001 and 2013 the number of breeding pairs of Adélie penguins (Pygoscelis adeliae) at breeding colonies in the southern Ross Sea more than doubled from about 235 000 to more than half a million. It has been suggested that predation release of Antarctic silverfish (Pleuragramma

10. Using spatial population models to investigate the effects of a proposed Marine Protected Area on Antarctic toothfish in the Ross Sea region

    Abstract:  One aim of Marine Protected Areas (MPAs) is to protect a representative portion of specific ecosystem functions through spatial closures to extractive practices such as fisheries. Although they usually involve the displacement of fisheries, their design rarely takes into account the
