  1. Advances are urgently needed in providing regular estimates of krill stock status based on the available data

    Abstract:  CCAMLR currently manages the krill fishery in subareas 48.1 to 48.4 using an arbitrary measure (the trigger level) which was established in 1991 and is “not related to the status of the krill stock”. At the same time, CCAMLR recognises that “advances are urgently needed” specifically

  2. Evidence of change to the environment, ecosystem and fishery within Area 48 indicates the need for continued precaution

    Abstract:  CCAMLR manages the krill fishery in Area 48 using a catch limit (the trigger level) which was established in 1991 based on the maximum catches reported for each subarea. Since that time the ecosystem has undergone rapid environmental change. Several studies suggest that krill numerical

  3. Towards the development of Marine Important Bird and Biodiversity Areas (mIBAs) for penguins in Antarctica – an update on progress

    Abstract:  Our study area encompasses all CCAMLR MPA Planning Domains contiguous to mainland Antarctica. We present the preliminary marine Important Bird and Biodiversity Areas (mIBAS) for penguins. A total of 64 definitive sites were identified as IBAs We present a systematic overview of the

  4. Reporting procedures for the continuous fishing method

    Abstract:  Commercial catch rates are important information for scientific evaluation of the krill resource and potential impacts of fishing on the ecosystem. Imprecise information confounds analysis and might undermine efficient and correct management actions. The following procedure now

  5. Revisiting krill ageing method using eyestalk cuticles

    Abstract:  The development of a consistent and reproducible ageing method for krill is critical for improving the precautionary management of krill fisheries. The only method to date that has shown promise in the determination of the absolute age of krill is that of Kilada et al. (2017), which

    Meeting Document : WG-EMM-2019/45 : Autor(es): S. Kawaguchi, T. Barnes, N. Waller, B. Farmer, D. Hayes, R. Kilada, C. Reiss, G. Zhu, B. Krafft, A.-L. Agnalt, T. Ichii and T. Matsuda

  6. Habitat use of type – C killer whales (Orcinus orca) in the Ross Sea, Antarctica

    Abstract:  In Terra Nova Bay, western Ross Sea, during the austral summer 2015 ten type- C killer whales were equipped withSmart Position Only (SPOT) and depth-recording satellite transmitters (SPLASH). Hierarchical switching state-space models (hSSSM) were applied to Argos satellite tracking data

  7. Long-term observations from Antarctica demonstrate that mismatched scales of fisheries management and predator–prey interaction lead to erroneous conclusions about precaution

    Abstract:  Low catch limits for forage species are often considered to be precautionary measures that can help conserve marine predators. Uncertainty about the impacts of fisheries removals on dependent predators bolsters this perspective, but consideration of the spatio-temporal scales over which

  8. Exploring trends of the krill fishery indicators among the NWAP D1MPA zones in the Subarea 48.1

    Abstract:  Domain 1 marine protected area (D1MPA) proposal has been developed sin 2012 and now has been intensively discussed. Its implementation will establish a new scenario for the current krill fishing fleet dynamic, therefore it is necessary to understand what represent each D1MPA zones for

  9. Detection of predator dive patterns from stationary echosounder data

    Abstract:  Standard protocols for processing of echosounder data are geared towards the estimation of biomass indices of pelagic organisms. More transient visitors to the watercolumn however also give echoes, and the data provided by the echosounders may be used to assess the behaviour of these

  10. Stable isotope analysis reveals trophic variation in adult Antarctic krill (Euphausia superba) around the Antarctic Peninsula from austral fall to early winter

    Abstract:  The Antarctic krill (Euphausia superba) is a key species in the Southern Ocean ecosystem and an important link in the food web of the Antarctic ecosystem. The trophic information for this species during the transition from the austral fall to the winter is important to understand its
