Proposal to continue participation in the second year of the joint CCAMLR research survey to collect spatially stratified longline and bathymetric data in 88.2_A and 88.2_B in 2015/16
Abstract: Toothfish in SSRUs 882.A–B are currently managed as part of the Ross Sea region stock, but the stock structure and fish movement patterns are uncertain and more information is required for the management across all of the region. Recognising this requirement, the Scientific Committee

Results of the longline survey for toothfish in the northern Ross Sea region (SSRU 88.2A) by the FV Seljevær, Norway
Abstract: A multi-year, multi-member research program was established to map and sample the fishable areas of SSRUs 88.2 A–B north of 66° S latitude. During the 5 th- 7 th February 2015, the Norwegian fishing vessel FV Seljevær surveyed SSMRU 88.2 A, research block 3, defined in the multi-Member

Investigations on tagging data in the Kerguelen Islands Patagonian toothfish fishery (division 58.5.1)
Abstract: In 2014, FSA-14-36r1 presented a new assessment of Patagonian toothfish in the French EEZ. A singularity in the tagging fits was observed by the working group. A lower number of recaptures in the first year compare to the second year was noted (figure1). This paper is an overview of

Marine ecosystem acoustics (MEA): quantifying processes in the sea at the spatio-temporal scales on which they occur
Abstract: Antarctic ecosystems are dynamic and characterized by physically forced variability caused e.g. by fronts, eddies and ice. This creates a challenging dynamics for scientific sampling and monitoring. Realistic understanding of what can and cannot be achieved with the available sampling

Exploratory longline fishing proposal for Dissosstichus spp. in Subarea 48.2
Abstract: A proposal for conducting a reserach cruise for Dissostichus spp. in Subarea 48.2 is presented by Chile. The proposal seeks to estimate presence and abundance of Dissostichus species in a data-poor area. The reserach proposed, if approved, will be conducted for three seasons. Author(s):

Scotia Sea Pygoscelid Penguin Tracking and Habitat Analysis Workshop
Abstract: During WG-EMM-14, it was noted that characterisation of overlap between land-breeding predators and the krill fishery was desirable throughout the Scotia Sea; it was recognised that such work could be advanced by either tracking animals originating from additional breeding colonies, or

Possible options for the future management of the Antarctic krill fishery in Subarea 48.2
Abstract: During 2013, WG-EMM agreed to form two inter-sessional task groups to progress work that might facilitate the development of new management procedures for the krill fishery in Area 48. In 2014, the state of ecological knowledge for Subarea 48.2 was reviewed, and it was suggested that the

A critical issue for feedback management – how do we determine the level of functional overlap between krill fishing operations and penguin foraging activity?
Abstract: The spatial distribution of the Antarctic krill fishery in Subareas 48.1 to 48.3 has changed over time. The majority of catches in Subarea 48.1 are now taken south of the South Shetland Islands, following regional decreases in seasonal sea-ice cover. As the cumulative spatial footprint

Acoustic and catch data collected by the fleet – relevance for feedback management
Abstract: The Norwegian fishing vessels involved in krill fisheries are also used to carry out abundance surveys around the South Orkney Islands. The involved companies have accepted running acoustic logging also during periods of commercial fishing. In this paper we give an overview of the

Antarctic krill; assessment of mesh size selectivity and escape mortality from trawls
Abstract: This working paper presents the aims and methodology for a three-year-project (commenced in 2015) assessing size selectivity and escape mortality of Antarctic krill from trawl nets. The project is widely based on acquired experiences from a completed study Net Escapement of Antarctic
