1. Revised research plan for the 2013/14 exploratory longline fishery of Dissostichus spp. in Subarea 48.6

   Abstract:  Catch and effort data recorded by all vessels were analyzed using the latest CCAMLR C2 and observer data. The stock size estimates for research blocks were revised following advice in the last WG-SAM meeting. We tentatively recalculated a sample size of Dissostichus spp in each block in

3. The relative by-catches of taxa associated with vulnerable marine ecosystems by autolines and Spanish longlines

   Abstract:  We reanalyzed data collected by the longline fishery in Subarea 88.1 to compare the bycatches of VME taxa made by vessels using Autolines and Spanish longlines. The fractions of sets with positive bycatch, as well as the weights of bycatch when bycatches were observed, were higher for

4. Fatty acid and stable isotope analyses to identify diets of Antarctic toothfish caught in February–March 2013 in the southern Ross Sea (88.1.K) and the eastern Antarctic Sea (58.4.1.C)

   Abstract:  To identify the important prey items for pre-recruit Antarctic toothfish in the SSRUs 88.1.K of the southern Ross Sea and 58.4.1.C of the eastern Antarctic Sea, their fatty acid (FA) composition and stable carbon and nitrogen isotope ratios were determined and compared to those of

5. Revised diet composition and feeding strategy of Antarctic toothfish, Dissostichus mawsoni in SSRU 58.4.1.C-a for the 2012/2013 Korean exploratory longline fishery

   Abstract:  Stocks of Dissostichus mawsoni in Division 58.4.1 were vulnerable with a big range of about 1,000-2,000 t per SSRU in Division 58.4.1. However, there is not enough data and information to assess the robust stocks and deliberate proper measurements for sustainable utilize, especially

6. Revised research plan for the exploratory longline fishery for Dissostichus spp. in SSRUs C and E in Division 58.4.1 in 2013/2014

   Abstract:  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 population sizes were vulnerable with a big range of about 1,000-2,000 t per SSRU in 58.4.1 and 100-1,500 t per SSRU in 58.4.2. During the 2003

7. Revised reproductive analysis of Dissostichus mawsoni in SSRU 58.4.1 C for the Korean exploratory longline fishery in 2012/2013

   Abstract:  In the Division 58.4.1 there are two stocks of Dissostichus mawsoni, which is vulnerable with a big range of about 1,000-2,000 t per SSRU in 58.4.1. However, there is not enough data to utilize stocks properly, especially relate to reproductive mechanism. Therefore, the Korean scientists

9. A characterisation of the toothfish fishery in Subareas 88.1 and 88.2 from 1997–98 to 2012–13

   Abstract:  This report summarises the timing, depth, and location of fishing together with the biological aspects and catch of Antarctic toothfish for the period 1997–98 to 2012–13. In 2012–13, all the Ross Sea slope SSRUs were clear of ice and catches were evenly distributed across the three SSRUs

10. Descriptive analysis of the toothfish (Dissostichus spp.) tagging programme in Subareas 88.1 & 88.2 for the years 2000–01 to 2012–13

    Abstract:  We provide an update of the descriptive analyses of the toothfish tagging programme in Subareas 88.1 and 88.2, including summaries of data for the 2013 season. Overall, a total of 37 047 Antarctic toothfish have been reported as released and 1903 recaptured, and 1155 Patagonian toothfish
