1. Net escapement of Antarctic krill in trawls

   Abstract:  This document describes the aims and methodology of a three year project (commenced in 2012) entitled Net Escapement of Antarctic krill in Trawls (NEAT). The study will include a morphology based mathematical modeling (FISHSELECT) of different sex and maturity groups of Antarctic krill

2. Impacts of ocean acidification on Antarctic krill biology: preliminary results and future research directions

   Abstract:  This study reports some preliminary results of the impacts of Ocean Acidification due to elevated seawater pCO 2 on the activity, mortality, moulting of post-larval krill.  Increased CO2 levels increased mortality, reduced activity levels and fitness, and caused moult cycle

3. Modelling growth and reproduction of Antarctic krill: implications of spatial and temporal trends in temperature and food for ecosystem-based management of krill fisheries

   Abstract:  Errors in the growth model used in stock assessments of Antarctic krill, specifically higher rates of growth than occur in reality, could inadvertantly lead to over-exploitation of the krill population and cause impacts on krill predators.  We review the three classes of models available

4. Towards developing a feedback management procedure for the Antarctic krill fishery

   Abstract:  We present a feedback strategy, founded on CEMP data, to adjust the catch limit and the spatial distribution of fishing activity for Antarctic krill in Statistical Area 48. The CEMP currently provides decades-long baseline time series and useful contrasts across areas and species that

5. Method for collecting of data on traumatic death of krill passed through the trawl meshes

   Abstract:  Fishing for krill Euphasia superba Dana has been conducting using midwater trawls of different constructions including beam-trawl for several last decades. Not all krill in harvesting zone of midwater trawl got to catch during trawling. Depending on stock structure, size and

7. Research and monitoring to support an MPA in the Ross Sea Region

   Abstract:  Conservation Measure 91-04 establishes the requirement for research and monitoring plans to support marine protected areas (MPAs).  Although CM 91-04 provides general guidance that such research and monitoring plans shall, to the extent necessary and inter alia, specify “(a) scientific

8. Proposal for a SCOR Working Group to identify Ecosystem Essential Ocean Variables for measuring change in the biological properties of marine ecosystems

   Abstract:  A proposal for a SCOR “Working Group to identify Ecosystem Essential Ocean Variables for measuring change in the biological properties of marine ecosystems” was developed by members of the Southern Ocean Observing System (SOOS) Science Steering Committee in conjuction with discussions

9. A proposal for compiling information, assessments and science that underpin established CCAMLR Marine Protected Areas and provide the basis for ongoing management, science and review: an MPA Report

   Abstract:  The General Framework for the Establishment of CCAMLR Marine Protected Areas in Conservation Measure 91-04 provides the necessary guidance to the Commission for formulating a conservation measure for a CCAMLR Marine Protected Area and indicates a number of elements where advice may be

10. Temporal variability in Adélie penguin CEMP parameters and their response to changes in prey availability

    Abstract:  We examined the within- and between- year fluctuations of four Adélie penguin population parameters which are thought to be sensitive to changes in prey availability: breeding success, foraging trip duration, meal mass and fledgling weights. Some years had either good breeding success
