1. Further investigations in the assessment of Antarctic toothfish (Dissostichus mawsoni) in Subarea 88.2 SSRUs 88.2C–H for the years 2002–03 to 2012–13

   Abstract:  This paper presents further investigations of the Bayesian sex and age structured population stock assessment of Antarctic toothfish (Dissostichus mawsoni) in Subarea 88.2 covering SSRUs 88.2C, D, E, F, G, and H (SSRUs 88.2C–H). Annual age-length keys were applied, and the time trends in

2. Calculating effective releases and recaptures for stock assessments based on tag detection and tagging mortality indices

   Abstract:  Vessel-specific indices of tag detection rates and tagging mortality rates have been developed using a methodology which controls for the spatial and temporal variability of fishing operations by pairing each individual tag release or recapture event with all other fishing events which

3. An updated spatially explicit population dynamics operating model for Antarctic toothfish in the habitable depths of the Ross Sea region

   Abstract:  We present an updated spatially explicit age-structured population dynamics operating model for Antarctic toothfish in the Ross Sea region, for a medium scale spatial resolution (189 spatial cells) covering the Ross Sea region. We build on the previous working medium-scale model in which

4. A proposed process for the management of model updates and software versions for stock assessment used within CCAMLR with the example of the CASAL software

   Abstract:  We propose a process by which to select the version of software generally used for stock assessments in CCAMLR, with the specific example of the CASAL software used for stock assessment. The latest published version of any stock assessment software approved by CCAMLR should be used by

5. Data and approach for the revised stock assessment for the Heard Island and the McDonald Islands Patagonian toothfish (Dissostichus eleginoides) fishery (Division 58.5.2)

   Abstract:  This paper presents the data and assessment approach for the revised stock assessment for Patagonian toothfish, Dissostichus eleginoides, at Heard Island and the McDonald Islands (HIMI) in CCAMLR Division 58.5.2. Since the last assessment in 2013, an extensive program for ageing otoliths

6. Preliminary examination of otolith microchemistry to determine stock structure in Antarctic toothfish (Dissostichus mawsoni) between SSRU 88.1C and 88.2H

   Abstract:  Life history characteristics of Antarctic toothfish (Dissostichus mawsoni), were evaluated using otolith microchemistry techniques. Our aims were to (i) determine whether fish from in CCAMLR SSRUs 88.1C (Ross Sea) and 88.2H (Amundsen Sea), could be differentiated by the trace elemental

7. Proposal for a longline survey of toothfish in the northern Ross Sea region (SSRUs 88.2 A and B)

   Abstract:  We propose a multi-year and multi-member research plan using standardised longline gear to sample the toothfish populations in the northern areas (61°- 66° S) of SSRUs 88.2A–B. The purpose of the research as requested by the Scientific Committee (SC-CAMLR XXXII, paragraph 3.76) is to

8. Nine years of tag-recapture in CCAMLR Statistical Subarea 48.3 – Part I: General data characterisation and analysis

   Abstract:  This paper presents an analysis of data gained from a nine-year tagging programme of Patagonian toothfish (Dissostichus eleginoides) in Subarea 48.3. It describes the tagging procedure, the information gained about biology, growth and movement of Patagonian toothfish, and explains the

10. The ICES Benchmark Protocol

    Abstract:  The ICES Benchmark Protocol is a review process for evaluating the data and analyses that form the basis of ICES management advice for a stock. The review examines stock structure, fishery characteristics, biological and assessment data, stock assessment and projection methodology. The
