1. STRUCTURE OF THE WATER MASSES AND KRILL DISTRIBUTION IN THE CENTRAL AND EASTERN PARTS OF THE ATLANTIC ANTARCTIC AREA

   Abstract:  The data of 18 expeditions fulfilled by AtlantNIRO during 1970-2000 in the central and eastern part of the Area 48 (Subareas 48.4 and 48.6) were summarized. Distribution of krill was analyzed with reference to the structure and dynamics of the water masses in the area of the Southern

2. COMPARING CEMP INDICES TO INFORM FEEDBACK MANAGEMENT OF THE ANTARCTIC KRILL FISHERY

   Abstract:  Despite uncertainties about interactions between ecosystems and fisheries, the ability to adjust activity of the Antarctic krill fishery based on the state of krill-dependent predators is a recognized goal of the CCAMLR. We suggest that progress toward a feedback management approach can

3. A RE-ANALYSIS AND UPDATE OF THE ANTARCTIC KRILL BIOMASS IN THE SOUTH SHETLAND ISLANDS, THROUGH 2011

   Abstract:  Acoustically based estimates of Antarctic krill (Euphausia superba) biomass, and net-based estimates of krill density and recruitment are recalculated for the years 1996 through 2011. Recent changes in the acoustic methodology and target strength models are the basis for the

4. REVISION OF THE CONSERVATION MEASURE 51-07 (2009) INTERIM DISTRIBUTION OF THE TRIGGER LEVEL IN KRILL FISHERY IN STATISTICAL SUBAREAS 48.1, 48.2, 48.3 AND 48.4

   Abstract:  Due to the need to distribute the krill catch limit in Statistical Area 48 so as to ensure that land-based predators are not affected by fishing activity, the Commission has adopted the interim Conservation Measure 51-07 (2009) since management advice on a SSMU krill catch limit

5. ASSESSMENT OF SPATIAL-TEMPORAL DYNAMICS OF STANDARDIZED CPUE FOR KRILL FISHERY IN THE AREA 48

   Abstract:  The spatial-temporal dynamics of standardized abundance indices of krill in Area 48 based on the CCAMLR catch statistics was analyzed using GLMM with Tweedie’s distribution.In the yesteryear the authors revealed “diagnostics specificity” of GLMM tuning for CPUE standardization: many

6. OPERATION PATTERN OF A JAPANESE COMMERCIAL KRILL FISHING VESSEL IN THE ANTARCTIC OCEAN

   Abstract:  This paper describes the general operation pattern of F/V Fukuei-Maru to help understand the actual condition of fishing and processing Antarctic krill in Japanese commercial trawl fishery. Special attention is paid to the calculation of green weight and conversion factors. Author(s):  F

7. UPDATE ON INTERSESSIONAL WORK BY THE SUBGROUP ON STATUS AND TRENDS ASSESSMENT OF PREDATOR POPULATIONS (WG-EMM-STAPP)

   Abstract:  This paper summarises inter-sessional work by WG-EMM-STAPP between 2009 and 2011 aimed at estimating krill consumption by pack ice seals, fur seals, penguins and flying seabirds in small scale management units (SSMUs) in Area 48 and in other CCAMLR Areas, and outlines a plausible

8. CURRENT ABUNDANCE OF ADÉLIE PENGUIN BREEDING POPULATIONS ALONG THE KEMP AND MAC.ROBERTSON LAND COASTS, EAST ANTARCTICA: APPLICATION OF NEW SURVEY AND ESTIMATION METHODS FOR BROAD-SCALE POPULATION ASSESSMENT

   Abstract:  Application of new methods for estimating the abundance of breeding Adélie penguin populations along the Kemp and Mac.Robertson Land coasts of east Antarctica are described. Methods include use of sample survey designs, distance sampling to estimate detectability, virtual delineation of

9. NEW REGIONAL-SCALE SURVEYS OF THE ADÉLIE PENGUIN BREEDING POPULATION IN PRYDZ BAY: A STEP TOWARDS IMPROVED ESTIMATION OF KRILL CONSUMPTION IN EAST ANTARCTICA

   Abstract:  Understanding circumpolar penguin abundance is critical for developing realistic ecosystem models that might be used to inform the management of impacts due to climate change or fisheries. A review of historical Adélie penguin survey data in east Antarctica revealed Prydz Bay as a

10. POTENTIAL PHENOLOGICAL RESPONSES TO ENVIRONMENTAL VARIABILITY AND CHANGE FOR ADÉLIE PENGUINS

    Abstract:  Phenological changes are touted to be an early indication of species response to environmental change and have been reported for a range of species around the globe. In Antarctica, there is a clear indication of phenological changes for the Adélie penguin (Pygoscelis adeliae) with
