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

Variability in krill length distribution in 48.1 derived from data collected by scientific observers
Abstract: Information on the length distribution of krill in the catch, and the spatial and temporal patterns of krill length in the population is essential to assess krill population status and dynamics, and the impacts of a fishery on the stocks. Here, we use generalised additive models (GAM)

Towards developing diagnostics tools for fishery stock assessments
Abstract: In this paper, we describe developments towards a set of standard diagnostic principles and tools used to characterise assessment models. CCAMLR has yet to develop a set of recommended statistical diagnostics tools to support their evaluations. While there are a number of standard visual

Joint CEP/SC-CAMLR workshop (2016) on climate change and monitoring
Abstract: The Committee on Environmental Protection and SC-CAMLR have endorsed the proposal to hold a second Joint CEP/SC-CAMLR Workshop in 2016. The agreed general scope of the workshop is to identify the effects of climate change that are considered most likely to impact the conservation of the

Preliminary report on krill survey off the coast of East Antarctica (Enderby Land to Prydz Bay) February-March 2015
Abstract: The Australian Antarctic research and resupply vessel, RV Aurora Australis, was directed to undertake an opportunistic marine science survey for 17 days during 21 February to 10 March 2015 using ship time that became available due to unexpectedly favourable ice conditions for Mawson

Chiller killers – first steps towards identifying krill pathogens
Abstract: Antarctic Krill (Euphausia superba) is a ‘keystone species’ in the Southern Ocean providing the main source of food for many taxa high in the food chain such as baleen whales, penguins and seals. Despite its ecological and economic importance, research into krill and other crustacean

Using vessel acoustics to detect diving patterns of krill foraging predators automatically: Development of a novel method for quantifying impact of krill fishing on seals and penguins
Abstract: The aim of this work was to assess the possibilities of automatically generating a dataset of dive behaviour of air-breathing predators, based on acoustic data from a monitoring survey and from commercial krill fishing operations. Our results documents that some form of automatic
