1. Revised biological parameters for the Antarctic skates Amblyraja georgiana and Bathyraja cf. eatonii from theRoss Sea

   Abstract:  Revised weight-length and length-length regressions are provided for Amblyraja georgiana and Bathyraja cf. eatonii. Significant differences between males and females occurred for all comparisons except for B. cf. eatonii length-length regressions. Some observer maturity staging data were

2. Development of methods for evaluating the management of benthic impacts from longline fishing using spatially explicit production models, including model validation

   Abstract:  An important management objective for CCAMLR in the high seas region of the Antarctic is to develop appropriate methods of monitoring and managing impacts of bottom fisheries on vulnerable marine ecosystems (VMEs). We describe a spatially explicit production model that can be used to

3. Developing a Ross Sea region medium-term data collection plan

   Abstract:  Data are collected for use in scientific research, the results of which are used to inform management decisions made to achieve specific goals. Any data collection plan should be drawn from the goals the management wishes to achieve. The Scientific Committee has recommended the

4. DNA barcoding highlights a cryptic species of grenadier (genus Macrourus) in the Southern Ocean

   Abstract:  The genus Macrourus is a small group of bentho-pelagic fishes with three species recognized in the Southern Ocean and one in cold temperate to Arctic waters in the North Atlantic Ocean. DNA barcoding revealed low intra-species (0.0-0.002) and inter-species (0.006-0.020) sequence

5. Non-target species in the Patagonian toothfish fishery inside the French EEZ

   Abstract:  This paper describes spatial and bathymetric distribution of fish bycatches inside the French EEZ for the longline fishery. Author(s):  N. Gasco (France) Title:  Non-target species in the Patagonian toothfish fishery inside the French EEZ Approval:  Approved

6. Results of the research fishing activities conducted by Chile in Management A of Subarea 48.3 from 2005–2008: the importance of conserving the big older fishes

   Abstract:  This research makes a contribution to the Agenda Item 8 of the WG-FSA. (Biology, ecology and demography of target and by-catch species) and shows the response of the local population of Dissostichus eleginoides (TOP) from the Area management A (subarea 48.3), after 4 year of closure

7. On necessity of longline fishery and research of Antarctic toothfish in all SSRUs of Subareas and Divisions 88.1, 88.2, 58.4.1, 58.4.2

   Abstract:  The analysis of catch size composition, statistical data on catches and distribution of Antarctic tooth-fish, and tagging data showed that the existing system of fishing subarea partition into SSRUs, open and closed for fishery, resulted in a lack of overall picture of population

8. Estimation of the 2011 catch limit for mackerel icefish (Champsocephalus gunnari) in Subarea 48.3 using a length-based population dynamics model

   Abstract:  A length based projection model is employed 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

9. Results of the groundfish survey carried out in CCAMLR Subarea 48.3 in January 2010

   Abstract:  In January 2010, the UK carried out the annual groundfish survey in CCAMLR Sub-Area 48.3 on the FV Sil. Seventy-five random hauls were completed with good coverage across the shelf, representing an increase in effort overall compared with surveys carried out in 2008 and 2009 on the same

10. Some aspects of the by-catch fish spawning and oogenesis

    Abstract:  On the basis of the biological material collected on some by-catch fishes during Antarctic toothfish fishery from 2002 till 2008 in different areas of the Southern Ocean (Collaboration Sea, D'Urville, Ross and.mundsen Seas) it was established that spawning of C. dewitti and species
