2. POPULATION SUBDIVISION IN THE ANTARCTIC TOOTHFISH (DISSOSTICHUS MAWSONI) REVEALED BY MITOCHONDRIAL AND NUCLEAR SINGLE NUCLEOTIDE POLYMORPHISMS (SNPS)

   Abstract:  The Antarctic toothfish (Dissostichus mawsoni) exhibits a circumpolar distribution in coastal waters south of the Antarctic Polar Front. For a preliminary evaluation of global population structure in this species, we examined four mitochondrial regions and 13 nuclear gene fragments in

3. RECRUITMENT AND BODY SIZE IN RELATION TO TEMPERATURE IN JUVENILE PATAGONIAN TOOTHFISH (DISSOSTICHUS ELEGINOIDES) AT SOUTH GEORGIA

   Abstract:  Recruitment variability in juvenile Patagonian toothfish (Dissostichus eleginoides), a commercially important, deepwater nototheniid fish, was examined at the sub-Antarctic island of South Georgia, South Atlantic. Data from 13 demersal trawl surveys conducted over a 20-year period were

4. SOME FIELD MATERIALS ON AREA AND SEASON OF ANTARCTIC TOOTHFISH SPAWNING

   Abstract:  On the results of some field materials collected from 2002 till 2008, on the basis of length composition analysis of individuals, weight of females’ gonads and sex ratio an attempt was made to select locations and periods of Antarctic toothfish mass spawning in some areas of the Pacific

6. IDENTIFYING PATTERNS IN DIET OF MACKEREL ICEFISH (CHAMPSOCEPHALUS GUNNARI) AT SOUTH GEORGIA USING BOOTSTRAPPED CONFIDENCE INTERVALS OF A DIETARY INDEX

   Abstract:  Ontogenetic, inter-annual and regional variations in diet were investigated in mackerel icefish, Champsocephalus gunnari, in three successive summer seasons around South Georgia. Stomachs from 2239 icefish (130-560 mm total length) were examined. A bootstrapping technique was used to

7. BIOMASS ESTIMATES AND SIZE DISTRIBUTIONS OF DEMERSAL FINFISH ON THE ROSS SEA SHELF AND SLOPE FROM THE NEW ZEALAND IPY-CAML SURVEY, FEBRUARY-MARCH 2008

   Abstract:  during February and March 2008 as part of the International Polar Year. The main aim of the survey was to carry out a Census of Antarctic Marine Life in this regionfocussing on sampling the pelagic and benthic habitats on the shelf, slope, abyss, and seamounts in the Ross Sea region

8. PRELIMINARY RESULTS OF TRIALS TESTING MODIFIED LONGLINE GEAR ‘TROTLINES’ IN PRESENCE OF CETACEANS IN SUBAREA 48.3

   Abstract:  1. Paired trials were undertaken to compare toothfish catch rates and by-catch composition on Spanish system longlines with those on ‘trotlines’ fitted with cetacean exclusion devices (cachalotera nets). 2. CPUE (kg/1000 hooks and kg/set) was greater for trotlines than Spanish system

9. PROPOSAL FOR REVISING CONSERVATION MEASURES 24-02 (2005) AND 41-03 (2006) IN RELATION TO SUBAREA 48.4

   Abstract:  The provisions for fishing season and mitigation measures in Conservation Measure 24-02 (2005) regulating fishing in Subarea 48.4 do not currently conform to the IMAF Risk Assessment advice given in CCAMLR-XXIV/BG/26. The UK proposes text that should be added to CM 24-02 to bring the

10. Proposal for an extension to the mark recapture experiment to estimate toothfish population size in Subarea 48.4

    Abstract:  1. So far a total of 929 D. eleginoides have been tagged and released at Subarea 48.4 and 25 tagged fish have been recaptured, including 23 during the latest season. 2. A preliminary assessment of D. eleginoides stock size in the Northern Area of 48.4 estimates a vulnerable biomass of
