2. A SIMULATION STUDY TO DETERMINE THE RELATIONSHIP BETWEEN SAMPLING INTENSITY AND PRECISION WHEN ESTIMATING AVAILABILITY FUNCTIONS FOR BREEDING ADÉLIE PENGUIN COLONIES

   Abstract:  Automated camera systems deployed at Adélie penguin breeding colonies provide daily measurements that allow high resolution temporal availability functions to be estimated, which in turn can be used to correct population estimates for availability bias. However, such frequent data are

3. ANTARCTIC KRILL DEMOGRAPHY AND POPULATION DYNAMICS WEST OF THE ANTARCTIC PENINSULA IN 2010/11

   Abstract:  A krill net sampling survey was carried out west of the Antarctic Peninsula in January 2011 to collect data on krill distribution, abundance, demography, spawning and recruitment success. The survey was a joint German and US effort. While the US AMLR Survey section covered the area

4. SELECTIVITY OF CONVENTIONAL AND CONTINUOUS TECHNIQUES OF KRILL FISHERY

   Abstract:  Combination of conventional and continuous techniques during krill fishery at the Russian commercial vessel "Maxim Starostin" allowed to compare the size structure of the Antarctic krill (Euphausia superba) caught by these two techniques. Results of comparison are discussed in

5. 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

6. 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

7. 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

8. 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

10. THE ASAM 2010 ASSESSMENT OF KRILL BIOMASS FOR AREA 48 FROM THE SCOTIA SEA CCAMLR 2000 SYNOPTIC SURVEY

    Abstract:  In June 2010 the CCAMLR ASAM working group examined the acoustic methodology applied to the CCAMLR 2000 synoptic survey data to generate a quality checked krill biomass for area 48 following the acoustic protocol identified in ASAM 2009. The total biomass of krill in the Scotia Sea was
