1. AGE AND GROWTH OF SPINY ICEFISH, CHAENODRACO WILSONI REGAN, 1914, OFF JOINVILLE-D'URVILLE ISLANDS (ANTARCTIC PENINSULA)

   Abstract:  Age and growth of spiny icefish, Chaenodraco wilsoni, were investigated using counts of annual growth increments from sagittal otoliths. Samples were collected during research surveys by benthic trawl carried out off Joinville-D’Urville Islands (Antarctic Peninsula) in February-March

2. INVESTIGATING LENGTH AT MATURITY OF ANTARCTIC TOOTHFISH (DISSOSTICHUS MAWSONI) BASED ON SCIENTIFIC OBSERVERS’ DATA

   Abstract:  Through generalised linear models, the gonadosomatic index of Antarctic toothfish in the Ross Sea region was shown to vary with latitude, length and month. Limitations of the scientific observers’ staging data were highlighted and GSI is recommended as a better indicator of maturity

3. THE ROSS SEA ANTARCTIC TOOTHFISH FISHERY: REVIEW OF THE 3-YEAR EXPERIMENT AND DEVELOPMENT OF MEDIUM-TERM RESEARCH OBJECTIVES AND AN OPERATIONAL FRAMEWORK FOR THE FISHERY

   Abstract:  The aim of this paper is to review the recent management of the Ross Sea toothfish fishery (including the 3-year experiment), to identify key operational and research objectives for the fishery over the next 5–7 years in relation to Article II of the Convention, and to develop an

4. ANALYSIS OF ROSS SEA TAGGING AND RECAPTURE RATES

   Abstract:  1. A dataset of all possible combinations of release nation, recapture nation, release year and recapture year for tags released and recaptured in the same SSRUs on the slope of 88.1 was compiled for the years 2003-2006. Recapture rate was expressed as tags captured/tags released/fish

5. RECONSTRUCTION OF SIZE AND WEIGHT COMPOSITION OF ANT-ARCTIC TOOTHFISH (DISSOSTICHUS MAWSONI) FROM THE DATA ON PROCESSED COMMERCIAL CATCHES OF LONGLINERS USING CONVERSION FACTOR

   Abstract:  Reconstruction of size and weight composition of Antarctic toothfish (Dissostichus mawsoni) from the data on processed commercial catches of longliners using conversion factor Author(s):  I. Istomin, K. Shust and V. Tatarnikov (Russia) Title:  RECONSTRUCTION OF SIZE AND WEIGHT

6. AN ECOSYSTEM-BASED MANAGEMENT PROCEDURE FOR KRILL FISHERIES: A METHOD FOR DETERMINING SPATIALLY-STRUCTURED CATCH LIMITS TO MANAGE RISK OF SIGNIFICANT LOCALISED FISHERIES IMPACTS ON PREDATORS.

   Abstract:  In this paper, we develop an ecosystem-based, precautionary management procedure for krill fisheries which draws together past experience in CCAMLR. It provides an empirical ecosystem assessment model, a decision rule for determining local scale catch limits based on a harvest strategy

7. AN UPDATED DESCRIPTION AND PARAMETERISATION OF THE SPATIAL MULTI-SPECIES OPERATING MODEL (SMOM )

   Abstract:  An updated version of the Spatial Multi-species Operating Model (SMOM) of krill-predator-fishery dynamics is described. This has been developed in response to requests for scientific advice regarding the subdivision of the precautionary catch limit for krill among 15 small-scale

8. A PROPOSED MANAGEMENT PROCEDURE FOR THE TOOTHFISH (Dissostichus eleginoides) RESOURCE IN THE PRINCE EDWARD ISLANDS VICINITY

   Abstract:  Four Operating Models (OMs) reflecting an “Optimistic”, “Intermediate”, “Less Pessimistic” and a “Pessimistic” current status for the toothfish resource in the Prince Edward Islands region are developed which take account of the different selectivities of past longline and pot fisheries.

9. EXTRAPOLATING CONTINUOUS PLANKTON RECORDER DATA THROUGH THE SOUTHERN OCEAN USING BOOSTED REGRESSION TREES

   Abstract:  nnovative multivariate statistical modelling techniques make it possible to generate spatially comprehensive species distribution layers from discontinuous biological data, by fitting complex and scale-dependent relationship between species abundance and available environmental data.

10. Variation in foraging effort by lactating Antarctic fur seals: response to simulated increased foraging costs

    Abstract:  Seasonally breeding predators, which are limited in the. time available for provisioning young at a central location, and by the fasting abilities of the young, are likely to maximize energy delivery to the young by maximizing the rate of energy delivery averaged over the whole period of
