Effects of Fish Meal Replacement with Fermented Antarctic Krill Meal on Growth Performance, Body Color and Serum Biochemical Indexes of Koi Carp (Cyprinus carpio L.)

Progress in Fishery Sciences, 2023
To investigate the effects of replacing fish meal with fermented Antarctic krill meal on growth performance, body color, and serum biochemical indexes of koi carp, 450 koi carp with an average body weight of (4.92±0.22) g were randomly divided into five ...

Self-organization and information transfer in Antarctic krill swarms

bioRxiv, 2021
Antarctic krill swarms are one of the largest known animal aggregations. However, despite being the keystone species of the Southern Ocean, little is known about how swarms are formed and maintained, and we lack a detailed understanding of the local ...

Refining Zooplankton Diet Composition Studies Over Short and Long Time Scales by Combining 18S Metabarcoding With Fatty Acid Analyses

Molecular Ecology Resources, Volume 25, Issue 8, November 2025.
ABSTRACT Understanding diet composition is essential for unravelling trophic interactions in aquatic ecosystems. DNA metabarcoding, utilising various variable regions of the 18S rRNA gene, is increasingly employed to investigate zooplankton diet composition.

The First Genome Survey of the Antarctic Krill (Euphausia superba) Provides a Valuable Genetic Resource for Polar Biomedical Research

Marine Drugs, 2020
The world-famous Antarctic krill (Euphausia superba) plays a fundamental role in the Antarctic food chain. It resides in cold environments with the most abundant biomass to support the Antarctic ecology and fisheries.

Antarctic krill (Euphausia superba) as a bioindicator of trace elements reflects regional heterogeneity in marine environments in the northern Antarctic Peninsula, Antarctic

Ecological Indicators, 2022
The northern Antarctic Peninsula (NAP) supports a few human activities. It is affected by intense climate change and anthropogenic threats. Antarctic krill (Euphausia superba) is the largest, by mass, in the Southern Ocean and is the keystone species in ...

Bottom‐Up Interactions in State‐Space Age‐Structured Models Using Mass‐Balance Dynamics

Fish and Fisheries, Volume 26, Issue 6, Page 1048-1064, November 2025.
ABSTRACT Age‐structured models are used worldwide to regulate fisheries. These models typically ignore top‐down interactions (predation affecting natural mortality) and bottom‐up interactions (consumption affecting individual growth, reproduction, or survival), whereas multispecies catch‐at‐age models often incorporate top‐down but not bottom‐up ...

Research on the Application of Green Ecological Additive Combinations During the Breeding Period of Redclaw Crayfish

Aquaculture, Fish and Fisheries, Volume 5, Issue 5, October 2025.
ABSTRACT The three key processes in the breeding of redclaw crayfish are nutrient enhancement by parents, catching and hatching of egg‐holding crayfish and maintaining a feed supply for juveniles. An appropriate combination of green ecological additives is beneficial for improving the production efficiencies of the three key processes.

Compound Marine Heatwaves and Acidity Extremes in the Southern Ocean

Global Biogeochemical Cycles, Volume 39, Issue 10, October 2025.
Abstract Compound extremes of temperature and acidity that extend over substantial fractions of the water column can be particularly damaging to marine organisms, as they experience not only additional stress by the potentially synergistic effects of these two stressors, but also a reduction in habitable vertical space. Here, we detect and analyze such

Past research and future directions in understanding how birds use their sense of smell

Ibis, Volume 167, Issue 4, Page 853-881, October 2025.
Our understanding of the functional importance of olfaction to birds has improved over the past 60 years, largely as the result of experimental studies testing how birds use their sense of smell in different contexts. As it is impossible to measure directly which odours birds can detect, we rely on measuring behavioural responses to scent cues or ...
