ANTARCTIC-WIDE GEOMORPHOLOGY AS AN AID TO HABITAT MAPPING AND LOCATING VULNERABLE MARINE ECOSYSTEMS
Abstract: Publicly available bathymetry and geophysical data can be used to map geomorphic features of the Antarctic continental margin and adjoining ocean basins at scales of 1:1-5 million. These data can also be used to map likely locations for some Vulnerable Marine Ecosystems. Seamounts over a

A DATABASE OF LIFE-HISTORY ATTRIBUTES FOR HABITAT-FORMING BENTHIC TAXA
Abstract: A global database of life-history characteristics, including growth rate, age, maximum size and reproductive parameters, was established for benthic, habitat-forming taxa and associated physical and chemical variables, including depth, temperature, oxygen concentration, salinity and

UPDATE OF THE INTEGRATED STOCK ASSESSMENT FOR THE PATAGONIAN TOOTHFISH (DISSOSTICHUS ELEGINOIDES) FOR THE HEARD AND MCDONALD ISLANDS USING CATCH-AT-AGE DATA AND TWO YEARS OF SURVEY ABUNDANCE-AT-AGE DATA
Abstract: The integrated assessment of Patagonian toothfish, Dissostichus eleginoides, for the Heard and McDonald Islands (Division 58.5.2) was updated by replacing catch-at-length proportions from commercial catches with catch-at-age proportions using age length keys (ALKs) where the ALK for each

ABUNDANCE AND BIOLOGICAL INFORMATION ON TOOTHFISH IN DIVISION 58.4.4a & b BY SHINSEI MARU NO. 3 IN 2007/08 SEASON
Abstract: A survey was conducted in order to collect information for the stock status and various biological information on toothfish in Division 58.4.4a & b by using a commercial bottom longline vessel, Shinsei Maru No. 3, from July 23 to September 27, 2008. The survey was undertaken in two

RESEARCH PLAN FOR TOOTHFISH IN DIVISION 58.4.4a & b BY SHINSEI MARU NO. 3 IN 2009/10
Abstract: In order to clarify stock status and biological characteristics of Dissostichus spp. in Division 58.4.4 a & b, a total of 124 research hauls are allocated on 10-minute latitude x 20-minute longitude grid points (spaced approximately 10 nautical miles apart). Almost all of the

ANTARCTIC TOOTHFISH STOCK ASSESSMENT IN DIVISION 58.4.1 ON THE BASIS OF CPUE DATA
Abstract: An attempt to use CPUE data based on data of erussian observers in the assessment of Antarctic toothfish stock in division 58.4.1 is made. Unlike some previous results obtained for this division (e.g. WG-SAM-08/4), the assessment was intended to be independent of estimates of toothfich

ADDING CATCH AT AGE AND SURVEY DATA TO THE 48.3 TOOTHFISH CASAL ASSESSMENT
Abstract: The catch-at-age based CASAL model for toothfish in Subarea 48.3, which was presented in 2007, is developed and extended here to include survey data. Additional adjustments to the model suggested by WG-FSA-2007 are implemented. Fits to the survey length frequencies are good for recent

EXPLORING THE ROBUSTNESS OF THE CURRENT TOOTHFISH SPP. HARVEST CONTROL RULES AND POTENTIAL EXPLOITATION RATE-BASED ALTERNATIVES
Abstract: In this paper a simple biomass dynamic population model is used as a paradigm for the dynamics of toothfish spp. in the CCAMLR area. This model underpins a management strategy evaluation framework where the process of stock assessment, TAC calculation and implementation and potential

LENGTH-BASED ASSESSMENT FOR THE MACKEREL ICEFISH (CHAMPSOCEPHALUS GUNNARI) IN SUB-AREA 48.3
Abstract: The current assessment method for the mackerel icefish (Champsocephalus gunnari) in sub-area 48.3 employs the CMIX and GYM packages, deriving population numbers-at-age then projecting these numbers forward under the given harvest control rule to set a two-year TAC. One issue is the

DRAFT SOFTWARE USER GUIDE FOR: ICESCAPE: INTEGRATING COUNT EFFORT BY SEASONALLY CORRECTING ANIMAL POPULATION ESTIMATES
Abstract: The ICESCAPE Software Users Guide (Appendix 1) describes a parametric bootstrap (Davison and Hinkley 1997) model for implementing the general abundance estimator proposed by Southwell (2004) for Antarctic land-breeding predators. The software, which was developed as a suite of routines
