1. A spatially explicit population dynamics operating model for Antarctic toothfish in the habitable depths of the Ross Sea region

   Abstract:  We present a 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. In this model run we spatially restrict the stock to cells where at

2. Further review of CCAMLR tagging programmes

   Abstract:  We review tagging protocol changes made in 2012/13 and provide further recommendations to improve the quality of collected tagging programme data, and conduct research to improve effective tag releases and recoveries. We also provide a tagging training module to inform vessel observers

3. Priority research surveys to address uncertainties in the assessment of toothfish in Subareas 88.1 and 88.2

   Abstract:  We have identified key uncertainties in the stock assessment of Antarctic toothfish in Subareas 88.1 ad 88.2 which could be addressed using specific research surveys and other dedicated voyages. Given the continued uncertainty arising from the relative paucity of abundance data, age and

4. Proposal to extend fishing season in the Patagonian toothfish longline fishery in CCAMLR Statistical Division 58.5.2

   Abstract:  This paper proposes extending the fishing season in the Patagonian toothfish longline fishery in CCAMLR statistical division 58.5.2 on a trial basis during the 2013/14 and 2014/15 fishing seasons by a further two weeks. This would increase the fishing season to include the period from 1

5. Proposal to extend trial of daytime setting of longlines between 15 and 30 April in the Patagonian toothfish longline fishery in CCAMLR Statistical Division 58.5.2

   Abstract:  This paper proposes extending the trial of daytime setting of longlines between 15 and 30 April in the Patagonian toothfish longline fishery in CCAMLR Statistical Division 58.5.2 to encompass the 2013/14 and 2014/15 fishing seasons.  Extending the trial for a further two years will

6. Steps carried out to check the data inputs to the stock assessment of the Ross Sea region of Antarctica

   Abstract:  We detail the procedure followed to check the Ross Sea CCAMLR fisheries data prior to using them in a stock assessment of Antarctic toothfish (Dissostichus mawsoni). The R codes used in this procedure have been made available to the Secretariat. Author(s):  S. Mormede (New Zealand) and S

7. Comparison of catches for toothfish in 58.4.1, 58.4.2, and 48.6 from vessels with anomalous CPUE

   Abstract:  An accurate history of catch is an important input into the assessment of toothfish stocks, and uncertainty or bias in the amount of catch from an area must be taken into account in the assessment of a stock. In 2013, Korea held a workshop on the anomalous CPUE data reported from some

10. Study on reproductive biology of Champsocephalus gunnari, Chaenocephalus aceratus and Pseudochaenichthys georgianus from South Georgias and Shag Rocks, Dr Eduardo Holmberg survey – May 2013

    Abstract:  The reproductive biology of C.gunnari, C. aceratus and P.georgianus was studied on samples taken around South Georgias and Shag Rocks. The macroscopic analysis indicated the presence of totally mature females of three species (with hydrated oocytes). C. gunnari, C. aceratus and P.
