1. Preliminary assessment of mackerel icefish (Champsocephalus gunnari) in the vicinity of Heard Island and McDonald Islands (Division 58.5.2), based on a survey in March–April 2010, including a revised growth model

   Abstract:  A survey of mackerel icefish, Champsocephalus gunnari, was undertaken in Division 58.5.2 in the vicinity of Heard Island in March-April 2010 to provide the information for an assessment of short-term annual yield in the 2010/2011 CCAMLR season. This paper provides a preliminary

2. How much do icefish (Notothenioidei, Channichthyidae) eat in the southern Scotia Arc and the Antarctic Peninsula region?

   Abstract:  Ration and daily food consumption in 3 low-Antarctic (Champsocephalus gunnari, Chaenocephalus aceratus, and Pseudochaenichthys georgianus), and 3 high-Antarctic (Chionodraco rastrospinosus, Cryodraco antarcticus, and Chaenodraco wilsoni) ice fish species were estimated around islands of

3. Stability of trip selections for the assessment of Antarctic toothfish in the Ross Sea

   Abstract:  A dataset for the 2009 assessment of Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea was selected on the basis of data quality metrics for individual trips. Initial informative datasets were selected comprising trips with high (above median) rates of recovery of previously

4. 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

5. 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

6. 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

7. 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

9. 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

10. 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
