1. Oxygen and carbon stable isotopes in otoliths record spatial isolation of Patagonian toothfish (Dissostichus eleginoides)

   Abstract:  Strong contrasts in ambient isotope ratios and in diet suggest stable isotopes in the otoliths of oceanic fish can resolve water masses and geographic areas, promising a powerful multivariate approach for examining population structure and provenance. To test this, whole otoliths were

2. SLOPE CURRENTS AROUND THE KERGUELEN ISLANDS FROM DEMERSAL LONGLINE FISHING RECORDS.

   Abstract:  rrent (ACC), especially around the Kerguelen Islands. However, there is little quantitative knowledge of the current field around the islands due to lack of long-term current measurements. We performed a systematic analysis of a total of 28917 points of fishing gear drifts from setting

6. 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

7. 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

8. 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

9. 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

10. 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
