Antarctic krill habitat suitability variation in the Southern Ocean over 20 years

Frontiers in Marine Science
Antarctic krill (Euphausia superba) is a key species that sustains the biodiversity of the Southern Ocean and is a protected and restricted fishing target in this region. Considering the significant impacts of climate change on the ecological environment

Divergent exploratory‐avoidant behavioural strategies may drive niche differentiation in juvenile Antarctic fishes

Journal of Fish Biology, EarlyView.
Abstract We used an ecological niche theory framework integrating physiological and behavioural ecology to understand interspecific differentiation of juveniles of four Antarctic fishes: Trematomus bernacchii, Trematomus pennellii, Trematomus nicolai and Pagothenia borchgrevinki.

Two scales of distribution and biomass of Antarctic krill (Euphausia superba) in the eastern sector of the CCAMLR Division 58.4.2 (55°E to 80°E).

PLoS ONE, 2022
Regular monitoring is an important component of the successful management of pelagic animals of interest to commercial fisheries. Here we provide a biomass estimate for Antarctic krill (Euphausia superba) in the eastern sector of the Commission for the ...

Characterization of Molecular Species and Anti-Inflammatory Activity of Purified Phospholipids from Antarctic Krill Oil

Marine Drugs, 2021
The phospholipids (PLs) from Antarctic krill oil were purified (>97.2%) using adsorption column chromatography. Forty-nine PL molecular species were characterized by ultrahigh-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (

Estimating Patagonian toothfish (Dissostichus eleginoides) length at first maturity from their age, sex and temperature experience around South Georgia

Journal of Fish Biology, EarlyView.
Abstract Patagonian toothfish (Dissostichus eleginoides) are a long‐lived, slow‐growing deep‐sea species endemic to the Southern Hemisphere and the focus of longline fisheries managed to ensure sustainable exploitation. Managing the fisheries relies on accurate stock assessments that include pertinent biological and exploitation processes.

Determination of fluoride in Antarctic krill (Euphausia superba) using ion chromatography and its pretreatments selection

Czech Journal of Food Sciences, 2015
A rapid, sensitive and reliable method to quantify fluoride in Antarctic krill has been established. Four different pretreatment methods were used for the extraction of fluoride: double-deionised water extraction, sulphuric acid distillation ...

Enabling Under Ice Glider Operations: A Backseat Driver Approach

Journal of Field Robotics, Volume 43, Issue 5, Page 3292-3311, August 2026.
ABSTRACT Polar Oceans are key locations for forcing global ocean circulation, influencing both global climate and biogeochemical cycles. Due to restricted access to these seasonally and perennially ice‐covered regions, these areas are severely undersampled.

Successful ecosystem-based management of Antarctic krill should address uncertainties in krill recruitment, behaviour and ecological adaptation

Communications Earth & Environment, 2020
Understanding of Antarctic krill must be at the heart of krill fishery management in order to protect the stock and its predators, according to a synthesis of krill ecology research.

Flume Tank Evaluation on the Effect of Liners on the Physical Performance of the Antarctic Krill Trawl

Frontiers in Marine Science, 2022
The Antarctic krill (Euphausia superba) is one of the most abundant resources in the ocean, which provides food for several important species in the Antarctic Ocean, and is targeted commercially by humans for many decades.

High‐Resolution Particle Imaging Reveals the Importance of Phytodetrital Aggregate Flux and Mesopelagic Grazing for Carbon Storage in the Southern Ocean

Global Biogeochemical Cycles, Volume 40, Issue 8, August 2026.
Abstract The biological, chemical, and physical processes in the mesopelagic zone that impact carbon flux to the deep ocean are poorly understood, particularly in the Southern Ocean, despite their importance to deep ocean carbon storage. Using a CTD‐mounted underwater imaging system, the Underwater Vision Profiler 5, we observed distributions of large ...
