1. Krill: the power lunch of Antarctica

   Abstract:  For several years, ASOC has been calling for improved management of Antarctic krill fisheries. In this paper, ASOC urges CCAMLR to continue to work towards requiring 100% scientific observer coverage on board krill vessels, identifying priority objectives for research and development in

2. A perspective on steepness, reference points, and stock assessment

   Abstract:  We provide a perspective on steepness, reference points for fishery management, and stock assessment. We first review published data and give new results showing that key reference points are fixed when steepness and other life history parameters are fixed in stock assessments using a

3. A false positive in the CCAMLR tag overlap statistic arising from low catch volume and consequent limited sample size

   Abstract:  The draft CCAMLR compliance report has recorded that when fishing in Subarea 88.2 in 2013/14 the vessel Argos Georgia achieved a tag overlap statistic of 52% rather than the required minimum of 60% as specified in CM 41-01. A review of the data indicates that the number of fish tagged

4. Steepness for Antarctic toothfish (Dissostichus mawsoni) based on life history

   Abstract:  Although steepness is typically considered a convenient re-parametrization of a stock-recruitment relationship, it is deeply rooted in the biology of each species.  Furthermore, specifying steepness and other life-history parameters such as natural mortality and growth rates fixes

5. Maturity stages for skates (Rajiformes)

   Abstract:  Current CCAMLR maturity stages for skates (Rajiformes) use a three-stage key. As such, important elements of the reproductive cycle may go unrecorded, including females in the process of egg-laying. Additionally, the current description of females at stage 2 (maturing) in the CCAMLR

6. An integrated stock assessment for the Heard Island and the McDonald Islands Patagonian toothfish (Dissostichus eleginoides) fishery (Division 58.5.2)

   Abstract:  This paper presents an updated assessment for Patagonian toothfish (Dissostichus eleginoides) at the Heard and the McDonald Islands (Division 58.5.2) with data until mid August 2014. This paper presents a bridging analysis and proposes a new base case assessment model which is based on

8. Results of the Spanish exploratory longline fishery for Dissostichus spp. in Divisions 58.4.1 and 58.4.2 in the two previous seasons

   Abstract:  We addressed the revisions requested by the WG-SAM-14 regarding the results of the second year of Spanish research experience and ongoing research plan presented in WG-SAM- 14/12 and WG-SAM-14/09.  A summary of the results of the Spanish research that took place in the 58.4.1 division

9. Updated and revised stock assessments of Patagonian toothfish (Dissostichus eleginoides) in the vicinity of Kerguelen Islands (Division 58.5.1) and Crozet Islands (Subarea 58.6)

   Abstract:  An updated and revised assessment of the Patagonian toothfish (Dissostichus eleginoides) stocks in Kerguelen and Crozet areas is presented. This study is based on a CASAL (C++ Algorithmic Stock Assessment Laboratory) model. Different statistical and biological datasets are used: catches,

10. Revised research plan for the exploratory longline fishery for Dissostichus spp. in Subarea 48.6 in 2014/15

    Abstract:  Most things related to Dissostichus spp. in the eastern side of Antarctic has not been known well as namely the area is data poor areas. In the Division 58.4.1 there are two stocks; one extends from the SSRU 58.4.1C to the SSRU 58.4.2A, and the other one to the SSRU 58.4.1H. The
