The Southern Ocean is fundamentally important to the Earth system, influencing global climate, biogeochemical and ecological cycles. Limited observations suggest the Southern Ocean is changing, yet chronic under-sampling makes the causes and consequences of such changes difficult to assess, and limits the effectiveness of any response. A Southern Ocean Observing System (SOOS) is thus being Read More

The present document is an update of document EMM-16/52, presenting refine analysis of the krill fishing hotspots and a description of the daily CPUE pattern for the krill fishery. This paper has now been accepted for publication in Fisheries Research.

Results identified several fishing hotspots (FHs), where the fleet took 48 to 57% of the seasonal catch, and are relatively Read More

In order to understand and mitigate for the potential impacts of anthropogenic disturbance on marine predators it is fundamental to gain insight into the drivers behind the temporal variation in their current distribution. With this in mind, we used Platform Terminal Transmitter (PTT) devices to track Adélie and chinstrap penguins breeding on the South Orkney Islands during the pre-moult phase Read More

We aim to investigate the qualitative changes in the habitats of two most common species penguin populations in the Wilhelm Archipelago Pygoscelis papua (gentoo) and Pygoscelis adeliae (Adelie) penguins in the CCAMLR Subarea 48.1 under the impact of climate changes and krill fishery. To minimize the effect of human disturbance on the breeding success Read More

There is increasing interest in using higher-trophic level predators as ecosystem indicators because their performance is presumed to be linked to the overall function of the ecosystem that supports them. In the southwest Atlantic sector of the Southern Ocean, Antarctic krill (Euphausia superba) supports huge predator populations as well as a growing commercial fishery.  To Read More

Резюме:

The abundance of the Antarctic krill (Euphausia superba) has been declining in the western Antarctic Peninsula (WAP), probably as a consequence of the effects of the considerable increase in the sea surface temperature observed in the region. Thus, the performance (reproduction and survival) of the krill consumers may be compromised. In the present study, we investigated the Read More

Age information for commercial fish species is crucial to fishery management. Age information for Antarctic krill (Euphausia superba) will be important for stock assessment modeling and future feedback management of krill fisheries. Samples stored in 70% ethanol provide an opportunity to detect the growth bands of eyestalk sections. Moreover, information derived from samples preserved Read More

Understanding the energy flux through food webs is important for estimating the capacity of marine ecosystems to support stocks of living resources. This paper provides a summary of a review on currently available Southern Ocean energetic density data. This review is a result of the Southern Ocean Diet and Energetics Database, an initiative of the SCAR Expert on Group Birds and Marine Mammals Read More

Резюме:

Antarctic krill Euphausia superba is an ecological key species in the Southern Ocean and a major fisheries resource. The winter survival of age class 0 (AC0) krill is susceptible to changes in the sea-ice environment due to their association with sea ice and their need to feed during their first winter. However, our understanding of their overwintering diet and its variability is Read More

• The Antarctic region is characterized by complex interaction of natural climate variability and anthropogenic climate change that produce high levels of variability in both physical and biological systems, including impacts on key fishery taxa such as Antarctic krill.

• The impact of anthropogenic climate change in the short-term could be expected to be related to changes in sea ice Read More

This paper presents a ‘first-step’ proposal for CCAMLR to consider the effects of environmental variability and change on management advice from toothfish assessments. We focus on changes to environmental conditions that are maintained over a number of years, which includes the effects of global climate change. The effects of environmental variability and change on toothfish population Read More

Recognising that CM 51-07 is scheduled to lapse at the end of the 2020/2021 fishing season, we outline a plan of work to engage with the CCAMLR community to move towards refining the krill risk assessment framework. WG-EMM has previously offered advice about how the risk assessment might be improved for the future. We therefore indicate key areas for community engagement to help develop the Read More

We review reasons why the fishery for Antarctic krill is challenging to manage and consider ways in which management could be improved, whilst responsible and precautionary harvesting continues. We propose an experimental framework to help improve the scientific basis for management. This framework will enhance conservation, and increase ecological understanding by using an experimental Read More

In this paper we drawn comparison between the existing CCAMLR Ecosystem Monitoring Programme (CEMP) and plans to develop Research and Monitoring Plans for Marine Protected Areas. We recall the outcomes of the CEMP Review in 2003, and as a result highlight the intensity of monitoring required to detect change and to ascribe cause. We therefore propose that CCAMLR build even stronger links with Read More
