1. SOME POSSIBLE MODIFICATIONS TO CEMP STANDARD METHODS A3A, A3B AND A9 TO ALLOW GREATER FLEXIBILITY IN THE COLLECTION AND INTERPRETATION OF BREEDING POPULATION COUNT DATA

   Abstract:  At WG-EMM-09 the Working Group noted that the photographic method used in WG-EMM-09/38 could be incorporated as a modification of CEMP Standard Method A3 (penguin breeding population size). This paper reviews aspects of Methods A3a, A3b and related A9 (breeding chronology) in the most

2. ANALYSIS OF VARIABILITY OF KRILL SIZE AND FISH BY-CATCH IN JAPANESE KRILL FISHERY BASED ON SCIENTIFIC OBSERVER DATA

   Abstract:  To investigate spatio-temporal variability of krill body length and number of bycatch fish, observer data sets on Japanese krill fishery from 1995 to 2008 were analyzed by using a hierarchical Bayesian model. The model was composed of multistage cluster units (i.e., years, subarea,

3. ANNUAL CHANGES IN SPECIES COMPOSITION AND ABUNDANCE OF BY-CATCH FISH COLLECTED BY JAPANESE KRILL SCIENTIFIC OBSERVERS IN THE NORTH OF SOUTH GEORGIA (CCAMLR SUBAREA 48.3), DURING AUSTRAL WINTER FROM 2002 TO 2008

   Abstract:  Species composition and abundance of by-catch fish were analyzed using the fish by-catch samples collected by scientific observers onboard Japanese commercial krill fishing vessels in the north of South Georgia during the austral winter from 2002 to 2008. A total of 19 species belonging

4. ANTARCTIC PENINSULA DECADAL WINTER TEMPERATURE ANOMALIES AND ANTARCTIC KRILL VARIABILITY IN THE SOUTH ATLANTIC REGION: PRELIMINARY RESULTS

   Abstract:  The influence of the climate change on krill based Southern Ocean ecosystem is studied intensively last decade. To study the possible connections between Antarctic Peninsula regional climate warming and ecosystem changes the data of Antarctic krill density (KRILLBASE data) and of surface

5. OPTIMISING THE DESIGN OF LARGE-SCALE GROUND SURVEYS OF ADÉLIE PENGUIN ABUNDANCE USING VIRTUAL SIMULATION IN A GEOGRAPHIC INFORMATION SYSTEM

   Abstract:  One of the recommendations for future work from the 2008 Predator Survey Workshop was ‘....that alternative census methods for large (penguin) colonies may be helpful. Such methods include the use of satellite imagery and the use of GPS receivers to accurately map colony areas from which

6. MODELLING ANTARCTIC KRILL: SCALE, MOVEMENT AND AGE‐STRUCTURE

   Abstract:  The organization, example outputs, and future objectives of an integrated, age‐structured model designed to estimate krill population dynamics and productivity are described. The model's capabilities are illustrated using 19 years of survey data collected by the U.S. AMLR Program

7. OCCURRENCE OF DWARF MINKE WHALES (BALAENOPTERA ACUTOROSTRATA SUBSP) AROUND THE ANTARCTIC PENINSULA

   Abstract:  The occurrence of dwarf minke whales (Balaenoptera acutorostrata subsp.) around the Antarctic Peninsula was examined based on 406 sightings of minke whales recorded during the Chilean Antarctic Scientific Expeditions and other opportunistic cetacean surveys. Identification of the species

8. DISCRIMINATION OF ENVIRONMENTAL VARIABLES THAT INFLUENCE THE CATCH PER UNIT EFFORT: THE CASE OF THE ANTARCTIC KRILL FISHERY

   Abstract:  The use of the catch per unit effort (CPUE) as an index of abundance usually requires a standardization process consisting of isolating all those exogenous factors from temporal variations in abundance from the CPUE time-series. These exogenous factors include those generated by

9. Research plan for toothfish in Divisions 58.4.4a and b by Shinsei Maru No. 3 in 2011/12

   Abstract:  A tagging survey in SSRUs B and C in Division 58.4.4 a & b was initiated in the 2010/11 fishing season with the aims of providing the data required for assessments of the population structure, size, movement and growth of Dissostichus spp. in the centered area of Division 58.4.4 a

10. Principles for evaluating data collection plans in data-poor exploratory fisheries

    Abstract:  Since 1992, CCAMLR has agreed that exploratory fishing is not to be allowed to expand faster than the acquisition of information necessary to ensure that the fishery can and will be conducted in accordance with the principles set forth in Article II of the Convention. However, several
