3. ANALYSIS OF THE POTENTIAL FOR AN ASSESSMENT OF TOOTHFISH STOCKS IN DIVISIONS 58.4.1, 58.4.2

   Abstract:  Exploratory fisheries for Dissostichus spp. have been operating in these regions for a number of consecutive years with the tagging of toothfish a prerequisite for the legal fishery. This paper presents a detailed study of the catch and effort trends in Divisions 58.4.1 and 58.4.2 and a

4. EXPLORATORY ASSESSMENT METHODS FOR EXPLORATORY FISHERIES: AN EXAMPLE CASE USING CATCH, IUU CATCH AND TAGGING DATA FOR DIVISION 58.4.3A

   Abstract:  This paper details a potential methodology for performing initial stock assessments for exploratory fisheries and by-catch species, where catch data and mark-recapture data are present but more detailed data, specifically age or length structured data on catches or surveys, is either

5. DEFINING TAG RATES AND TACS TO OBTAIN SUITABLY PRECISE ABUNDANCE ESTIMATES FOR NEW AND EXPLORATORY FISHERIES IN THE CCAMLR CONVENTION AREA

   Abstract:  This paper outlines a method of calculating suitable tagging rates and total allowable catches (TACs) that would be expected to yield a pre-specified precision in a resultant abundance estimate. With respect to the tagging-based abundance estimator, we use the Lincoln-Petersen method and

6. DEVELOPMENT OF A METHODOLOGY FOR DATA QUALITY ASSESSMENT

   Abstract:  Measures are developed which aim to summarise the quality of fishing event, catch, and biological sampling data from a fishing trip. In particular these measures aim to quantify the prevalence of position or time reporting errors, the diversity of catch, the extent to which catch data

7. DEVELOPMENT OF A SPATIALLY EXPLICIT AGE-STRUCTURED STATISTICAL CATCH-AT-AGE POPULATION DYNAMICS MODEL FOR MODELLING MOVEMENT OF ANTARCTIC TOOTHFISH IN THE ROSS SEA

   Abstract:  We present a generalised spatially explicit Bayesian statistical catch-at-age population dynamics model (SPM) for developing and investigating plausible spatial movement models, and apply a preliminary development version of this model to Antarctic toothfish in the Ross Sea as an age and

8. IMPLEMENTATION OF FOOSA (KPFM) IN THE EPOC MODELLING FRAMEWORK TO FACILITATE VALIDATION AND POSSIBLE EXTENSION OF MODELS USED IN EVALUATING KRILL FISHERY HARVEST STRATEGIES THAT WILL MINIMISE RISK OF LOCALISED IMPACTS ON KRILL PREDATORS

   Abstract:  This paper details how FOOSA, an operating foodweb model for evaluating spatially-structured harvest strategies for krill, has been implemented within the EPOC modelling framework. It also shows how the parameters developed for use in FOOSA can be adapted for use in EPOC. The paper has

9. RESOURCES EVALUATION OF ANTARCTIC KRILL EUPHAUSIA SUPERBA DANA USING AREAL TRAWLING AND HYDRO-ACOUSTIC DATA

   Abstract:  Quantitative method for describing krill mass congestions based on perennial observations using trawling and hydroacoustic data is proposed. Reliable evaluation of krill resources is provided with probability methods and spatial analyses requiring knowledge of statistical distribution

10. METHODOLOGY OF EVALUATING THE AQUATIC LIFE RESOURCES

    Abstract:  ic life is developed in accordance with the rules of metrology, mathematical statistics and using the biocenological regularities of water objects. The basis of evaluating the stocks of water life was investigated through biocenotic conditionality in the areas of their equal probability
