Krill physiology and impact of temperature variations: a comparative approach
Abstract: The purpose of this "paper" is to present a research project in progress on the physiology of Antarctic krill, with a focus on the response to environmental temperature variations. This study first focused on the study of heat shock proteins (HSP) and the comparative aspect

Unfolding connectivity patterns along the Antarctic Circumpolar Current in the sub-Antarctic region
Abstract: The sub-Antarctic region-here considered between the sub-Antarctic Front and the southern boundary of the Antarctic Circumpolar Current (ACC)-falls under many distinct jurisdictions, including Exclusive Economic Zones (EEZs) of several countries, as well as the areas of competence of

Extinction risk of Antarctic and sub-Antarctic colonies of Pygoscelid penguins under climate change context
Abstract: Several studies have emphasized the variable abundance of Pygoscelid penguins from different colonies around Antarctica. In this study, the extinction risk of Adélie, Chinstrap and Gentoo penguins was evaluated in order to identify the most endangered colonies under present-day and

Important marine mammal areas (IMMAs) – scientific protocol
Abstract: The Marine Mammal Protected Areas Task Force (MMPA Task Force) was established in 2013 by the International Committee on Marine Mammal Protected Areas (ICoMMPA), the International Union for Conservation of Nature (IUCN), the Vice-Chair of the World Commission on Protected Areas (WCPA),

Supervised and unsupervised (RapidKrill) estimates of krill density from DY098
Abstract: We compare supervised, using the interactive software Echoview™, and unsupervised, using python, processing of acoustic data collected during the UK cruise DY098. The same data processing procedures are applied in both methods, and we show that the unsupervised method comes

Preliminary biomass estimation of Antarctic krill based on the swarm-based method for CCAMLR Division 58.4.1 in 2018/19 using data obtained by Japanese survey vessel Kaiyo-maru
Abstract: Biomass (B 0) of Antarctic krill for CCAMLR Division 58.4.1 in 2018/19 was preliminarily estimated as 4.349 million ton (CV=54.8 %) based on the swam based method using data obtained by Kaiyo-maru. The point estimate was comparable with the estimate in 1996 by BROKE (4.83 million ton

Movements of tagged Antarctic toothfish (Dissostichus mawsoni) in Subarea 48.6 in relation to stock structure hypotheses
Abstract: We examined movements of tagged Antarctic toothfish (Dissostichus mawsoni) for subarea 48.6 in relation to life history hypotheses. Most of long-distance movements occurred in westward direction along continental shelf, which may be consistent with the single Atlantic population

Preliminary assessment of genetic diversity in bycatch-caught darkbelly skate (Bathyraja meridionalis) from South Georgia
Abstract: Reliable species identification and population assessments of skates are crucial for the sustainable management of their vulnerable stocks. However, species identification is a major challenge in skate studies due to convergent morphology within and between genera. In this study, we

Progress report on collaborative research for otolith chemistry of Antarctic toothfish Dissostichus mawsoni in the Southern Ocean
Abstract: Otolith chemical analysis is one of important and useful approaches to reveal the stock structure and connectivity of Dissostichus mawsoni in the Southern Ocean. Recalling the suggestion from WG-FSA 2018 about the international collaboration on otolith microchemistry of D. mawsoi, this
