1. 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

2. 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

3. 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

4. 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

5. 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

6. 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

7. 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

8. Microincrement analysis in otoliths of Notothenia rossii fingerlings from the South Shetland Islands to estimate early life history timings and to validate annulus formation

   Abstract:  In this study, otolith microstructure analysis on 7 blue phase fingerlings and 26 brown phase fingerlings selected from a total sample of 364 early juveniles caught mainly in summer from 2003 to 2010 at Potter Cove, South Shetland Islands, allowed to provide insights on early life

9. Linking fish and shags population trends

   Abstract:  This document analyses and relates long term information on population trends of inshore demersal fish and Antarctic shags of the South Shetland Islands. The analysis is complemented with comparable information on diet, foraging patterns and breeding output of shags from the Danco Coast,

10. A updated population status model for the Patagonian toothfish, Dissostichus eleginoides, at Kerguelen Islands (Division 58.5.1) using CASAL

    Abstract:  A stock assessment of the Patagonian toothfish (Dissostichus eleginoides) at Kerguelen Islands (CCAMLR Division 58.5.1) was undertaken using the modelling software CASAL, based on different statistical and biological datasets: abundance estimation from the POKER 1 (2006) and 2 (2010)
