1. Results from the groundfish survey conducted in CCAMLR Subarea 48.3 in January/February 2011

   Abstract:  The 2011 groundfish survey took place at South Georgia and Shag Rocks on the FV Sil between the 27th January and 6th February 2011. 87 random hauls were completed, with good coverage across the shelf. Catch-weighted length frequencies of mackerel icefish indicated that 3+ sized fish

2. The diet of toothfish species Dissostichus eleginoides Smitt and D. mawsoni Norman with overlapping distributions around the South Sandwich Islands, Southern Ocean

   Abstract:  The diet of Antarctic toothfish (Dissostichus mawsoni) and Patagonian toothfish (D. eleginoides) was examined around the south sandwich islands in the southern ocean, one of few regions with overlapping populations of the two species. Despite large differences in the proportion of

3. The Ross Sea toothfish fishery: proposal for conditional transition of classification from exploratory to established

   Abstract:  The Ross Sea toothfish fishery in Subarea 88.1 and 88.2A&B has been classified by CCAMLR as an exploratory fishery since 1998.  The current classification of this fishery as ‘exploratory’ has led to the widespread misconception that little information is available for this stock, and

5. Proposal to trial daylight setting on longliners fishing for Dissostichus eleginoides for a 10 day period during the middle of winter during the fishing season in Subarea 48.3

   Abstract:  Daylight setting is allowed in Subarea 48.4 and stringent mitigation measures have meant to date no bird mortalities have been recorded. Due to frequent storms vessels have been requesting the option to be able to set during daylight in Subarea 48.3 for safety reasons.  Recurrent

6. Recommendation for an explicit limit reference point for the mackerel icefish (Champsocephalus gunnari) fishery in CCAMLR Statistical Division 58.5.2

   Abstract:  Large fluctuations in abundance are a persistent feature of the populations of mackerel icefish (Champsocephalus gunnari) in the waters adjacent to Heard Island and the McDonald Islands in CCAMLR Statistical Division 58.5.2. The current decision rules for setting catch limits for icefish

7. Estimation of catch rate and mean weight in the exploratory Dissostichus fisheries across Divisions 58.4.1 and 58.4.2 using generalised additive models

   Abstract:  The exploratory longline fisheries in Divisions 58.4.1 and 58.4.2 (primarily targeting D. mawsoni) have been operating since 2003. Formal stock assessments have yet to be developed for these fisheries. Analyses of C2 catch rate and mean weight data from 2484 longline hauls conducted

8. Finfish by-catch in the krill fishery for the 2010 and 2011 seasons

   Abstract:  The fish sampling protocol (K12 form) was developed to ensure that small/larval fish, that  may go undetected in larger samples, are recorded using a sorting method with a standard sub-sampling approach that allows the user to re-sort smaller samples and maximises potential to detect by

9. Revised proposal for a CCAMLR sponsored research survey to monitor abundance of pre-recruit Antarctic toothfish in the southern Ross Sea

   Abstract:  At its 2010 meeting, the Scientific Committee agreed that a time series of recruitments from a well- designed survey in the Ross Sea could be a useful input into the stock assessment model and requested members develop a pre-recruit survey design. A preliminary proposal for a pre-recruit

10. Development of a generic operating model framework for data collection, assessment method and management strategy evaluations

    Abstract:  A generic spatially-explicit age-structured model framework is in development that will enable to evaluate data collection protocols, assessment methods and management strategies. The model framework is programmed in R to promote transparency and interactions between researchers. It is
