  1. 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 ...

  2. Numerical model of ecosystem including Euphausia superba Dana as a key species in the Antarctic Ocean

    Abstract:  On the processes to investigate a proper model for understanding the processes that ... govern the biochemical cycle in Antarctic Ocean, we made a research plan as follows: (1) to develop an ... OGCM (Ocean General Circulation Model) (2) to develop a one dimensional ecosystem model that can be ... ecology (4) to develop a numerical model to couple the OGCM and ecosystem models (5) to develop a ...

  3. A multivariate approach to examining patterns in research fishing activities using the SSRU 88.2A–B North survey as an example

    Abstract:  The WG-SAM in 2016 “agreed the importance of identifying a set of diagnostics and clear ... criteria to assess the likelihood that a vessel is operating as would be expected in normal research ... activities”, further noting that a characterisation of fishing activities was also required in order to ... achieve such a goal (WG-SAM 2016, paragraph 4.19). In this paper, we further develop the analysis of Large ...

  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. KRILLBASE: a multinational, circumpolar database of abundance of Antarctic krill and salps

    webs and biogeochemical cycles. Sustainably managing the fishery for Antarctic krill against a backdrop ... scientists has collated these disparate data into a central database called KRILLBASE, a composite ... aim is to provide a temporal-spatial data resource to support studies of Southern Ocean ecology ... led to a series of papers since 2004 that illustrate some of its potential uses. The latest version ...

  8. 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 ...

  9. Adélie penguin diet: a pilot study directly comparing data from stomach flushing with faecal DNA analysis

    composition and mass. Analysing prey DNA in faeces may be a useful, less invasive, approach to complement ... existing diet monitoring. 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 ...
