Monitoring variability in predator diets can highlight key parameters for understanding and managing marine ecosystems. Penguin diets provide useful indicators of ecosystem variability and several species, including Adélie penguins (Pygoscelis adeliae)…
The Southern Ocean surrounding Antarctica harbours some of the most pristine marine environments remaining, but is increasingly vulnerable to anthropogenic pressures, climate change, and invasion by non-native species.
Antarctic krill (Euphausia superba) are amongst the most abundant animals on Earth, with a circumpolar distribution in the Southern Ocean. Genetic and genomic studies have failed to detect any population structure for the species, suggesting a single panmictic population. However…
To manage a fishery effectively, it is crucial to understand the spatial stock structure of the target species, and how fishing mortality is distributed across the stock. This study investigates the genetic stock structure of Antarctic toothfish (Dissostichus mawsoni)…
Publication: 2019. Final Report, FRDC Project 2017/021. Australian Antarctic Division and the Fisheries Research and Development Corporation. Kingston, Australia. ISBN 978-1-876934-33-0. For this study, Antarctic toothfish samples were collected from CCAMLR Subareas 48.2, 48.4, 48.6, 88.1, 88.
Antarctic krill (Euphausia superba) is a keystone species of the Southern Ocean, vastly abundant and an essential food source of some of the Southern Ocean's most charismatic predators, including penguins, seals, and baleen whales. Antarctic krill are also targeted by a krill fishery…

Antarctic krill (Euphausia superba) is a keystone species in the Southern Ocean ecosystem, and monitoring its distribution and abundance is crucial for the sustainable management of expanding fisheries targeting the species. Environmental DNA (eDNA)…
