1. Revised reports on abundance and biological information on toothfish in Division 58.4.4 a and b by Shinsei Maru No. 3 in 2010/11 season

   Abstract:  A survey was conducted in order to collect information for the stock status and various biological information on toothfish in Division 58.4.4a & b (Ob Lena Bank) by using a commercial bottom longline vessel, Shinsei Maru No. 3, from March 30 to May 2, 2011. This report described the

3. Preliminary studies on age, growth and size at sexual maturity of Dissostichus eleginoides in the Ob-Lena Bank in the 2007/08 season

   Abstract:  Preliminary studies on the age, growth and size at sexual maturity of Dissostichus eleginoides sampled in the 2007/08 season in the Ob-Lena Bank were carried out. The ages of 214 of 3,013 fish sampled by Observers were estimated last year. Then, we took several advice and comments about

4. New data on depths inhabited by striped-eyed rock cod Lepidonotothen kempi (Norman) (Nototheniidae) off Bouvet Island

   Abstract:  In 2010 on the southern slope of Bouvet Island, I found L. kempi at still greater depth in the course of fishery for toothfish onboard of 1 Insung Korean longliner. In the first case, mature specimens with absolute length (TL) of 39–45 cm and weight of 0.8–1.3 kg were found in stomachs

5. Distribution and biological characteristics of two toothfish species of genus Dissostichus (family Nototheniidae) off Bouvet Island

   Abstract:  In 2010, two toothfish species, Patagonian (D. eliginoides) and Antarctic (D.mawsoni) toothfish, were registered during the fishery on Dissosyichus spp. on the shelf edge and slope of Bouvet Island. Their commercial concentrations were found also on the neighboring underwater plateaus

6. To the problem of spawning character for certain fish species

   Abstract:  The present paper presents the brief results of the research in reproductive biology of the Antarctic greinadier M. whitsoni in the Ross Sea. It was stated that the eggs were released by batches. It was supposed that the similar character of spawning might be for some other Antarctic

7. Connectivity and population structure in Pleuragramma antarcticum

   Abstract:  We used stable isotope and trace element chemistry from otoliths to test whether silverfish (Pleuragramma antarcticum) are distributed in independent, discrete populations in the Ross Sea, over the West Antarctic Peninsula, and around the South Orkneys; or whether the Southern Ocean

8. 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

9. 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

10. Update of the integrated stock assessment for the Patagonian toothfish (Dissostichus eleginoides) for the Heard and McDonald Islands (Division 58.5.2)

    Abstract:  The integrated assessment of Patagonian toothfish, Dissostichus eleginoides, for the Heard and McDonald Islands (Division 58.5.2) was updated from WG-FSA-09/20. The main change other than updating total removals by sub-fishery and updating catch-at-age and catch-at-length proportions was
