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. OTOLITH CHEMISTRY REFLECTS FRONTAL SYSTEMS IN THE ANTARCTIC CIRCUMPOLAR CURRENT

   Abstract:  Pronounced environmental trends across fronts suggest that the otolith chemistry of oceanic fish can resolve zones on either side, promoting application to population questions at similar spatial scales. Trace and minor elements laid down immediately prior to capture – along the edges of

6. OTOLITH CHEMISTRY INDICATES POPULATION STRUCTURING BY THE ANTARCTIC CIRCUMPOLAR CURRENT

   Abstract:  Large-scale transport of seawater in ocean currents may generate spatially complex population structure through the advection of life stages of marine fish species. To test this, we compared the chemistry of otolith nuclei from Patagonian toothfish (Dissostichus eleginoides), presently

8. 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

9. TOWARDS THE BALANCED STOCK ASSESSMENT OF ANTARCTIC TOOTHFISH IN THE ROSS SEA

   Abstract:  Last two years two different approaches were used for stock assessment of Antarctic toothfish in the Ross Sea. One of them, the CASAL model, (Dunn & Hanchet, 2007; Bull et al., 2007) is mostly based on likelihoods and potentially could insure proper mutual weighting of signals from
