2. GROUNDFISH SURVEY IN CCAMLR SUB-AREA 48.3 IN APRIL 2008 WITH PRELIMINARY ASSESSMENT OF MACKEREL ICEFISH

   Abstract:  In April 2008 the UK undertook a bottom trawl survey of CCAMLR Sub-Area 48.3 on the FV Sil, with 70 bottom trawls undertaken giving good geographic coverage. Using 10 strata and the updated sea-floor areas and adjusting this for the low headline height of the UK trawl (see CCAMLR WG-FSA

3. 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

4. A REVIEW OF THE METHODS USED TO RELEASE SKATES (RAJIIDS), WITH OR WITHOUT TAGS, IN ANTARCTIC EXPLORATORY FISHERIES

   Abstract:  An ongoing mark and recapture experiment for skates was commenced by New Zealand fishing vessels in the Ross Sea (CCAMLR Subareas 88.1 and 88.2) in 1999/2000. Based on preliminary results from this programme showing an unquantifiable degree of the survivorship of returned skates, the

5. 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

6. 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

8. 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

10. YEAR OF THE SKATE SAMPLING PROTOCOL: LEARNING FROM THE 2007–08 SEASON SAMPLING PROTOCOL ON NZ VESSELS

    Abstract:  Skates are an important bycatch of the toothfish fishery in the CCAMLR area and have been identified as priority taxa for which assessments of status are required (e.g., SC-CCAMLR XXIII 2004, paragraphs 4.172, 4.177 and 4.199). While Dunn et al. (2007) and Agnew et al. (2007) have
