1. Models of larvae dispersion of Antarctic toothfish (Dissostichus mawsoni)

   Abstract:  Antarctic toothfish (Dissostichus mawsoni) have a circumpolar distribution, and have been found associated with bathymetric features shallower than 2250 m and typically deeper than 500 m from the Antarctic continent north to approximately 57° S. Efforts to understand early life history

2. Summary of toothfish tagging suitability data from paired Spanish line – trotline sets

   Abstract:  Conservation Measure 41-01\Annex C requires participants in exploratory fisheries to only tag fish with a high probability of survival. Further it recommends that fish hooked only in the mouth should be tagged. A new data collection form was implemented in 2012 to allow evaluation of

3. Characterisation of Muraenolepis species by-catch in the CCAMLR Convention Area

   Abstract:  Muraenolepis species are caught in low numbers with bottom longline and trawl gears throughout the CCAMLR Convention Area. There are seven known species in the genus, but more work on the taxonomy of the group is needed and the number of species is uncertain. The few biological studies

4. Demersal fish communities in the Ross Sea region of Antarctica: comparisons between video and trawl survey methods

   Abstract:  Reliable estimates of demersal fish community composition and population densities are essential for understanding the ecological effects of fisheries. Such estimates are conventionally derived from research trawl surveys but video techniques afford an alternative, or complementary,

5. Diet of Antarctic toothfish (Dissostichus mawsoni) from the Ross Sea region, Antarctica

   Abstract:  The diet of Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea region was examined based on stomach samples obtained from observers on New Zealand fishing vessels in 2003 and 2010. Overall, the diet of sub-adult toothfish was similar to that of adult toothfish, with a dominance

6. Testing for genetic differentiation between two size classes of the starry skate (Amblyraja georgiana)

   Abstract:  Two size classes of A. georgiana have been described in by-catch fishing data reported in the catch data from the Ross Sea fisheries. We extracted DNA from A. georgiana samples from both size classes collected by Scientific Observers in the Ross Sea. We determined the DNA sequences of

7. plotImpact v2.0-2012

   Abstract:  Updated software is presented for the automated production of standardised image plots of spatially referenced bottom fishing impact assessments. This software is submitted to WG-FSA as an R library to assist the Secretariat or CCAMLR Working Groups in the production of integrated bottom

8. Can acoustic methods be used to monitor grenadier (Macrouridae) abundance in the Ross Sea region?

   Abstract:  Grenadiers Macrourus spp. are the main bycatch species in the exploratory longline fishery for toothfish Dissostichus spp. in the Ross Sea, Antarctica. Ongoing monitoring tools are needed to assess stock status of grenadiers in the Ross Sea and to ensure ecological relationships are

9. Fatty acid analysis to infer diet of Antarctic toothfish caught in February 2012 in the southern Ross Sea

   Abstract:  To infer important prey resources for Antarctic toothfish (Dissostichus mawsoni) in the south of SSRUs 881.J and 881.L in the southern Ross Sea, their lipid composition was determined and compared tolipid profiles of fish and invertebrate species taken as bycatch in the fishery or
