1. Results of scientific observation in Antarctic krill fishery in 2010/11: II. analysis of variability of krill size and fish by-catch

   Abstract:  We examined spatio-temporal variability of krill body length and number of bycatch fish as variables of interest based on the scientific observer data for the 2010/2011 fishing season. Both krill length and number of bycatch fish were analyzed by using a hierarchical Bayesian model

2. Preliminary observation about the possibility of Antarctic krill escapement from a trawl net

   Abstract:  We observed whether Antarctic krill escaped from the trawl net or not using an underwater video camera attached on the trawl net of Japanese commercial trawler Fukuei-maru (4,350.62 GT) in 2011. To avoid the influence of camera lighting on krill behavior, the observation was conducted

3. Proposals on providing international synoptic surveys for management application

   Abstract:  This paper briefly outlines the key scientific issues that should be resolved for providing sufficient information with the aim of quantitative understanding regularities and trends of krill spatial distribution in the Area 48 being the important information for developing management

4. Analysis of spatial and temporal structure in long-term krill fishery in the Area 48 and its relation to climate variability

   Abstract:  The authors   analyzed the influence of climate changes on space-time dynamic of Antarctic krill fishery in the Area 48 using the CCAMLR fishery data and time series of ААО induces (Antarctic Oscillation Index) as the indication of climate variability.   Here we used the methods of the

5. Analysis of variability of krill size and fish by-catch in Japanese krill fishery based on scientific observer data

   Abstract:  To estimate optimal relative sample size of scientific observer data collected on Antarctic krill commercial fishing vessels, we estimated the relationship between statistical precision and sample size by using variance component analysis. Observer datasets on Japanese krill fishery from

6. Penguin monitoring via remote sensing

   Abstract:  Picking up the calling of the ATCM XXXIV to the Treaty Parties to intensify their efforts in using remote sensing techniques for improved monitoring of environment and climate changes in the Antarctic, Germany currently carries out a feasibility study on penguin monitoring using such

7. Diet and trophic niche of Antarctic silverfish (Pleuragramma antarcticum) in the Ross Sea, Antarctica

   Abstract:  The diet of Antarctic silverfish (Pleuragramma antarcticum) was evaluated by examining stomach contents of specimens collected in the Ross Sea (71°–77°S, 165°E–180°) in January–March 2008. Silverfish (50–236 mm standard length, SL) and silverfish prey items were analysed for stable

8. The Ross Sea cephalopod community: insights from stable isotope analysis

   Abstract:  Based on mass balance modeling and mixed trophic impact analysis, cephalopods have been identified as having relatively high importance in the food-web of the Ross Sea. However, information on the trophic ecology of the cephalopod assemblage of the Ross Sea region is poor. Stable isotope

9. Diet and trophic niche of Macrourus spp. (Gadiformes, Macrouridae) in the Ross Sea region of the Southern Ocean

   Abstract:  Both Macrourus caml and M. whitsoni are probably abundant and widespread in the Ross Sea region at depths between approximately 500 and 2100 m. We present the analysis of stomach contents (including regurgitated stomach contents) from an undifferentiated mixture of 33 specimens of these

10. Slow recovery of previously depleted demersal fish at the South Shetland Islands, 1983–2010

    Abstract:  Following seals and baleen whales prior to the 1970s, demersal fish stocks were depleted off the South Shetland Islands by intensive industrial fishing during the late 1970s to early 1980s. Little has been reported since about how these stocks have fared, after international agreement
