2. Review of activities in monitoring marine debris in the CAMLR Convention Area

   Abstract:  In 2011 data on beach surveys, debris associated with seabird colonies, marine mammal entanglements and hydrocarbon soilings were received from South Africa, the United Kingdom, and Uruguay.  Non-fishing items such as packaging and wood remain the most common type of debris items found

3. Summary of a three year mark-recapture experiment to estimate population size of Antarctic toothfish (Dissostichus mawsoni) in Southern Area of Statistical Subarea 48.4

   Abstract:  A three-year tagging experiment was initiated by the UK in 2008/09 fishing season with the aims of providing the data required for assessments of the population structure, size, movement and growth of both Patagonian toothfish (Dissostichus eleginoides) and Antarctic tooth (Dissostichus

4. New gonad identification guides for Dissostichus eleginoides

   Abstract:  Difficulties in distinguishing between certain gonad stages is of common concern for observers onboard vessels fishing for Dissostichus eleginoides. To minimise errors in interpretation of maturity scales of D. eleginoides a comprehensive identification guide has been prepared. It is

5. Preliminary assessment of toothfish in Subarea 48.3

   Abstract:  As with the 2009 assessment of Subarea 48.3, there is still uncertainty as to why there were high numbers of the 2001 cohort in commercial catches in 2009 onwards.  It is likely that it is due to a combination of a strong 2001 cohort and a change in selectivity for the commercial fleet,

6. Preliminary assessment of mackerel icefish, Champsocephalus gunnari, in Subarea 48.3 using a length based population dynamics modelv

   Abstract:  A length-based projection model is used to estimate catch limits for the 2011/12 fishing season for Champsocephalus gunnari in CCAMLR sub area 48.3. The model is initialised using estimated numbers at length derived from survey length density and biomass density data, removing the need

7. Assessment of the Action Plan aimed at reducing incidental catch of seabirds in the French EEZ included in the CCAMLR Division 58.5.1 and Subarea 58.6

   Abstract:  France presented at CCAMLR XXVII an action plan aimed at reducing incidental avian mortality by 50% in the French EEZ included in the statistic division and subarea 58.5.1 and 58.6 for the period 2008/2009 to 2010/2011. The aim of this document is to present the various measures

8. PROPERTIES OF WATER DYNAMICS AND KRILL DISTRIBUTION IN THE SOUTH SANDWICH ISLANDS SUBAREA

   Abstract:  of mean krill density in Subarea 48.4 there are premises for formation of the zones with increased density. These zones are located within the near-shore shelf-based SSMU and associated with meanders and eddy favorable for krill concentration. Here, in the cold water of the Weddell Sea,

9. COMPARISON OF THE PRECISION OF DIRECT VERSUS AGE LENGTH KEY METHODS OF ESTIMATING CATCH-AT-AGE PROPORTIONS

   Abstract:  Catch-at-age proportions can be estimated directly using a simple random sample (SRS) of fish in the catch, determining the ages in the sample, and calculating proportions in each age class. This “direct” method can be replaced by the age length key (ALK) method if there are in addition

10. PRELIMINARY ASSESSMENT OF TOOTHFISH IN SUBAREA 48.3

    Abstract:  1. 2009 data have been incorporated in to the catch-at-age based CASAL model for toothfish in Subarea 48.3. 2. Fits to the survey data are good for the early 2000s, particularly 2004 to 2006. Fits to the catch at age data are good, except for 2009 where large numbers of age 7 and age 9
