1. Preliminary aspects of a simulation model to be used for evaluating the experimental crab fishery

   Antarctic crab fishery. A simulation model is proposed for conducting this work. Length frequency and catch ... fishery simulation is spatially explicit, and the dynamics of crab abundance are described on a daily ... basis. The simulation includes advective and diffusive movement rates, a lagged Beverton-Holt stock ... recruitment relationship, and a model for catch that contains a random normal deviate. Finally, an algorithm ...

2. A characterisation of the toothfish fishery in Subareas 88.1 and 88.2 from 1997/98 to 2009/10

   881H and 881I, with a reduced catch from 881K due to ice conditions. The catch limit in the north was ... 88.2E, but a slight decline in SSRU 882CDFG over the last two years. We carried out a more detailed ... characterisation of Patagonian toothfish catches for the first time. A total of 124 t of Patagonian toothfish has ... species identification be independently checked through examination of a subsample of otoliths from these ...

3. 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 ... a preliminary development version of this model to Antarctic toothfish in the Ross Sea as an age and ... numbers of areas, and is implemented as a discrete time-step state-space model that represents a cohort ... -based population age structure in a spatially explicit manner. The model is parameterised by both ...

6. A proposed research plan for an exploratory fishery for Dissostichus spp. in Division 58.4.3

   Abstract:  A new fishery was declared for Dissostichus spp in Division 58.4.3 for the 1996197 ... season. Results of a brief survey by an Australian vessel are presented, but catches were very low. A new ... proposal for an exploratory fishery in Division 58.4.3 is presented. This involves a random stratified ... trawl survey to be undertaken in parallel with commercial exploration, and the collection of a ...

8. Development of a spatially-explicit minimum realistic model for Antarctic toothfish (Dissostichus mawsoni) and its main prey (Macrouridae and Channichthyidae) in the Ross Sea

   Antarctic toothfish and its main prey, grenadiers (Macrouridae) and icefish (Channichthyidae), we develop a ... spatially explicit model using a predator-prey suitability model for the Ross Sea Region. We model the age ... fishing mortality on both prey species and that icefish is expected to show a larger increase in biomass ... through time than grenadiers. It also suggests that a prey-suitability function is more likely than a ...
