2. 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 ...

4. Towards a strategic framework for assessing uncertainty in ecosystem dynamics models: objectives are sensitive too

   of the precautionary catch limit for krill. Foosa might therefore be a suitable simulation platform ... for evaluating feedback management approaches. Although Foosa resembles a minimum realistic model, it ... . There is a global need to develop strategic frameworks for assessing uncertainty in ecosystem dynamics ... models. Such a framework could incorporate elements of the evaluation of Foosa, but it should also ...

5. A distribution-free model of length-frequency distribution to inform fishery stratification for integrated assessments

   Abstract:  Length frequency distributions (LFD) of catch collected as a random sub-sample from ... /or gear specific selectivity. A distribution-free model of LFD is described which is fitted to the ... set of length quantiles L for a predetermined set of corresponding probabilities P (in this instance ... fish. The L s were modelled as a Gaussian response variable using a Generalised Additive Mixed Model ...

6. 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 ...

7. Increasing abundance of Type A killer whales (Orcinus orca) in the coastal waters around the Antarctic Peninsula

   and we need to understand the impact on marine ecosystems. A diverse community of killer whales ... (Orcinus orca; Types B1, B2 and A) are important top predators around the AP, but there are currently no ... Antarctica. In contrast, less is known about the Type A killer whales that are more typical in appearance to ... killer whales sighted in other parts of the world.  Sightings of Type A around the AP have been ...

We undertook a pilot study to directly compare these two methods using Adélie ... /January) in 2014/15 and 2015/16. Each method produced a similar pattern of penguin diet, with a shift from ... almost exclusively krill in 2014/15 to a mixture of fish and krill in 2015/16. Stomach flushing allows ...
