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

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

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

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

Some properties of diagnostics of GLMM model tuning for standardising CPUE indices in the Area 48 using the CCAMLR fishery statistics database
Abstract: The data of krill fishery in Subarea 48 for 1986 – 2008 presented to CAMLR database by haul-by-haul data were used. Standardizing CPUE was performed by applying the generalized linear model with random effects (GLMM). The analysis of diagnostics of GLMM tuning indicated that the model

PRELIMINARY RESULTS OF THE EXPERIMENT ON DEFINITION OF ANTARCTIC KRILL MORTALITY RATE IN FISHERY
Abstract: Two successful experiments on definition of Antarctic krill mortality have been carried out aboard Polish vessel Dalmor II according to the pattern submitted in paper SC-CAMLR-XXVIII/BG/10. Approximately 230 to 130 kg of krill are percolated and punched through per an hour of trawling if

ANTARCTIC KRILL AND CLIMATE CHANGE
Abstract: During April 2011, a multi-national group of scientists with expertise on Antarctic krill Euphausia superba and environmental sciences attended a workshop aiming to evaluate new knowledge on the impact of climate change and increasing fisheries on Antarctic krill and Antarctic ecosystems

ESTIMATION OF MANAGEMENT REFERENCE POINTS CONSISTENT WITH THE CATCH TRIGGER LEVEL FOR THE ANTARCTIC KRILL FISHERY IN AREA 48
Abstract: The Generalised Yield Model was used to estimate fishing mortality and spawning stock biomass reference points for the krill fishery in CCAMLR Area 48 consistent with the catch trigger level of 620,000 tonnes. Projections were run with various increased levels of recruitment variability

USING ECOSYSTEM STRUCTURE TO IDENTIFY FINER-SCALE SSMUS FOR OCEANIC AREAS IN SUBAREAS 48.1 TO 48.3
Abstract: One of the main issues in the management of the krill fishery is finding a spatial subdivision of catches that allows CCAMLR to achieve its objectives for both the fishery and the ecosystem. This requires a framework of spatial areas over which catches can be subdivided. WG-EMM has
