1. 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

2. 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

3. 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

4. Summary of the work of the CEP on Marine Protected Areas

   Abstract:  At CEP XIV (2011), the Antarctic Treaty Secretariat presented Secretariat Paper 6   “Summary of the Work of the CEP on Marine Protected Areas”. This paper reports on the development of the topic of Marine Protected Areas (MPA’s) in discussions of the Committee for Environmental

6. Chinstrap penguins alter foraging and diving behaviour in response to krill size

   Abstract:  Penguins may exhibit plasticity in their diving and foraging behaviors in response to changes in prey availability. Chinstrap penguins are dependent predators of Antarctic krill in the Scotia Sea region. Both the sizes of krill found in penguin diets and acoustic estimates of krill

7. 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

8. 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

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
