1. Assessment of escape mortality of Antarctic krill (Euphausia superba) in trawls

   Abstract:  The overall purpose of this study was to estimate the mortality rate of Antarctic krill (Euphausia superba) that escape from the most common mesh size used in the current commercial fishery. The experiment was carried out on the krill fishing grounds off South Orkney Islands (60°35’S, 45

2. Development in maturity stage composition and vertical distribution in an Antarctic krill (Euphausia superba) hotspot

   Abstract:  Antarctic krill (Euphausia superba) aggregate in various ways depending on a range of factors, from biological (e.g. antipredatory behavior, social interactions and food availability) to physical forcing (e.g. advection and retention). Some areas, often associated with topographical

3. Report from the annual survey of Antarctic krill and apex predators distribution at South Orkney Islands in 2014, and assessing escape mortality of krill in trawls

   Abstract:  This report describes the work and preliminary results from the fourth annual survey conducted around the South Orkney Islands, using a commercial krill fishing vessel as research platform. The overall purpose is to describe taxonomy of the macrozooplankton community, demography and

4. Risk maps for Antarctic krill under projected Southern Ocean acidification

   Abstract:  The embryonic development of Antarctic krill (Euphausia superba) is sensitive to elevated seawater CO 2 levels and successful hatching is impaired at CO 2 levels greater than 1000 μatm. Exposure to elevated CO 2 during the first 3 days of embryonic development significantly retards

5. Review of the Russian marine researches in the south-eastern part of the Atlantic Antarctic Area (20°W–30°E)

   Abstract:  The review of Russian expeditions carried out during 1970-2000 in the south-eastern part of the Atlantic Antarctic Area was discussed. Distribution of krill with reference to the structure and dynamics of the water masses, species dominated in Phytoplankton and Ichthyofauna were analyzed

6. Background and criteria of establishment of Marine Protected Area (MPA) in the Weddell Sea

   Abstract:  Present work contains considerations and proposals of possible joint research of Russian and German scientists in the eastern part of the Weddell Sea. Data on potentially valuable for commercial fishing species in the eastern part of the Weddell Sea collected by German investigators in

7. Composition of Leucocytes in Peripheral Blood of Antarctic Toothfish Dissostichus mawsoni (Nototheniidae)

   Abstract:  The aim of the work is to study the leukocyte composition in blood of deep-water fish species by the example of Antarctic toothfish Dissostichus mawsoni. Fish were caught in January–February 2012 in the Ross Sea (Statistical Subarea 88.1) at depths from 690 to 1183 m from onboard “Yantar

8. Expanding Antarctic seabird monitoring in east Antarctica using a remote camera network: potential use for monitoring for feedback management

   Abstract:  Antarctic seabirds are important indicators of impacts and change in Southern Ocean ecosystems, but their isolated and remote breeding populations are challenging and expensive to assess and monitor using traditional methods. Remotely-operating time-lapse cameras offer a tool for cost

9. A proposed observer logbook for the 2015 krill trawl fishery

   Abstract:  During 2013 the CCAMLR Scheme of International Scientific Observation (SISO) was subject to an external review by an expert review panel drawn from members (see SC-CAMLR-XXXII/07 Rev. 1). The panel recommended a number of changes to the SISO observer logbooks to remove obsolete data

10. Estimation of the green weight of krill caught

    Abstract:  Vessels operating in the krill fishery in CCAMLR’s Convention Area have been required to directly estimate the green weight of krill caught since 2012/13. The estimation methods were revised at WG-EMM-13 and published in Conservation Measure 21-03 Annex B. Estimates of green weight and
