Pellet quality of krill meal and pea protein containing diets and their sinking velocity at different water temperature and salinity

Journal of the World Aquaculture Society, Volume 56, Issue 5, October 2025.
Abstract The present study investigated the effects of replacing low‐temperature fishmeal (LT FM) with graded levels of partly deshelled Antarctic krill (Euphausia superba) meal and pea protein concentrate (PDKM + PPC), PDKM alone, or whole krill meal with shells (WKM) as primary protein sources on feed pellet physical quality and sinking velocity (Sv)

Factors impacting the timing of reproductive development in female Antarctic krill at the northwestern Antarctic Peninsula

Frontiers in Marine Science
The northwestern Antarctic Peninsula is an important spawning, recruitment, and overwintering ground for Antarctic krill. The region is warming rapidly, and the current impacts of climate and environmental variability on the reproductive cycle of krill ...

An Update on the Occurrence of Humpback Whale ( Megaptera novaeangliae ) Super‐Groups on the West Coast of South Africa

Marine Mammal Science, Volume 41, Issue 4, October 2025.
ABSTRACT Humpback whale ( Megaptera novaeangliae ) super‐groups, comprising 20+, tightly aggregated, feeding individuals, form during the austral summer in the southern Benguela ecosystem off the west coast of South Africa. This phenomenon, observed since 2011, is thought to be linked to increased productivity from positive chlorophyll‐a anomalies ...

Drone‐Based Photogrammetry Provides Estimates of the Energetic Cost of Migration for Humpback Whales Between Antarctica and Colombia

Marine Mammal Science, Volume 41, Issue 4, October 2025.
ABSTRACT Monitoring the body condition of animals offers insights into their energetic needs, prey consumption, and vulnerability to environmental pressures. Southern hemisphere humpback whales ( Megaptera novaeangliae ) depend on Antarctic krill for their annual energy requirements.

Penguin guano suppresses the grazing rate and modifies swimming behavior in Antarctic Krill (Euphausia superba)

Frontiers in Marine Science
Antarctic krill (Euphausia superba) are a key component of the Antarctic ecosystem linking primary and some secondary production to higher trophic levels including fish, penguins, seals, and whales.

Effect of the polysaccharide addition, high‐intensity ultrasound, and high hydrostatic pressure on the rheological parameters of protein isolates: A mini review

Food Biomacromolecules, Volume 2, Issue 3, Page 366-376, September 2025.
Abstract Because of their rheological properties, proteins are essential ingredients in the development of new foods and the improvement of existing ones. Food acceptance depends mainly on the texture and sensation it produces in the mouth. Furthermore, rheological characteristics play a crucial role in the application of proteins in the food industry.

Changing circumpolar distributions and isoscapes of Antarctic krill: Indo‐Pacific habitat refuges counter long‐term degradation of the Atlantic sector

Limnology and Oceanography, 2020
The Southern Ocean provides strong contrasts in rates and directions of change in temperature and sea ice between its sectors, but it is unknown how these affect plankton species that are distributed right around Antarctica.

Mapping Antarctic Seabird Breeding Occupancy From a Century of Observations to Inform Environmental Management and Conservation

Diversity and Distributions, Volume 31, Issue 9, September 2025.
ABSTRACT Aim To map presence, absence and ignorance of Antarctic seabird breeding occupancy at the spatial resolution of ice‐free habitat sites to identify knowledge gaps and inform management and conservation. Location East Antarctica between longitudes 30° E and 150° E.
