1. LENGTH AND AGE AT SPAWNING OF ANTARCTIC TOOTHFISH DISSOSTICHUS MAWSONI IN THE ROSS SEA

   Abstract:  This study uses a histological assessment of age and length at spawning for female and male Antarctic toothfish Dissostichus mawsoni from fish sampled in the Ross Sea spanning the 2000-2009 fishing seasons. The female spawning ogive incorporates the proportion of sexually mature fish

2. DEVELOPING A ‘BEST AVAILABLE SCIENCE’ BATHYMETRIC DATA FRAMEWORK FOR FISHERIES MANAGEMENT IN THE ROSS SEA

   Abstract:  Bathymetric data are used inter alia to define management boundaries, implement conservation measures, allocate catch among area, estimate spatial impacts due to fishing, and inform ecosystem-based management through bioregionalisation. Several data sources for bathymetric data exist,

4. ASSESSMENT MODELS FOR ANTARCTIC TOOTHFISH (DISSOSTICHUS MAWSONI) IN THE ROSS SEA FOR THE YEARS 1997–98 TO 2008–09

   Abstract:  We provide an update of the Bayesian sex and age structured population stock assessment model for Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea (Subareas 88.1 and SSRUs 88.2A–B), using revised catch, catch-at-age, and tag-recapture data for the 2008–2009 season. The

5. ASSESSMENT MODELS FOR ANTARCTIC TOOTHFISH (DISSOSTICHUS MAWSONI) IN SUBAREA 88.2 SSRU E FOR THE YEARS 2002/03 TO 2008/09

   Abstract:  We provide an update of the Bayesian sex and age structured population stock assessment model for Antarctic toothfish (Dissostichus mawsoni) in the SSRU 88.2E, using revised catch, catch-at-age and tag-recapture data from New Zealand vessels and for selected trips. The New Zealand

6. FURTHER DEVELOPMENTS OF A SIMULATION MODEL, ‘PATCH’, FOR EVALUATING MANAGEMENT STRATEGIES TO CONSERVE BENTHIC HABITATS (VULNERABLE MARINE ECOSYSTEMS) WHICH ARE POTENTIALLY VULNERABLE TO IMPACTS FROM BOTTOM FISHERIES

   Abstract:  Bottom fisheries are now to ‘avoid significant adverse impacts on vulnerable marine ecosystems’ in order to maintain the ecological structure and function of, particularly, deep sea benthic habitats. Noting the paucity of data on the ecology of these habitats, this paper further develops

7. DISTRIBUTION AND ABUNDANCE OF SKATES ON THE KERGUELEN PLATEAU (CCAMLR DIVISIONS 58.5.1 AND 58.5.2)

   Abstract:  Three species of skates are commonly taken as incidental by-catch in the Patagonian toothfish longline and trawl fisheries, and the mackerel icefish trawl fishery on the Kerguelen Plateau, Bathyraja eatonii, B. irrasa and B. murrayi. The three skates are widely distributed across the

8. DEVELOPMENT OF RECOVERY PLANS FOR DEPLETED TOOTHFISH STOCKS IN THE INDIAN OCEAN SECTOR OF THE SOUTHERN OCEAN

   Abstract:  Stocks of Dissostichus mawsoni on BANZARE Bank (Division 58.4.3b) and D. eleginoides on Ob and Lena Banks (Divisions 58.4.4a and 58.4.4b) have been subjected to unsustainable levels of IUU and commercial fishing and it is likely that they are depleted below the threshold for CCAMLR

9. CONSERVING ANTARCTICA FROM THE BOTTOM UP: IMPLEMENTATION OF UN GENERAL ASSEMBLY RESOLUTION 61/105 BY THE COMMISSION FOR THE CONSERVATION OF THE ANTARCTIC MARINE LIVING RESOURCES (CCAMLR)

   Abstract:  The United Nations General Assembly (UNGA) Resolution 61/105 calls upon Regional Fisheries Management Organizations or Arrangements (RFMO/As) to take measures to prevent significant adverse impacts on vulnerable marine ecosystems (VMEs). In response to this CCAMLR has implemented a

10. NEW DATA ON MIGRATIONS OF ANTARCTIC TOOTHFISH DISSOSTICHUS MAWSONI NORMAN, 1937 (PERCIFORMES, NOTOTHENIIDAE) OBTAINED DURING IMPLEMENTATION OF THE PROGRAM ON DISSOSTICHUS SPECIES TAGGING IN THE LONGLINE FISHERY IN THE D’URVILLE SEA, 2008/09

    Abstract:  In fishing season, 2008/09, at implementation of the program on Dissostichus spp. tagging aboard Korean longliner “22 INSUNG”, in the D’Urville Sea for the short, period of time the new data on migration of one individual D.mawsoni were obtained. Supposedly, the speed of migration was
