Effects of Replacing Fish Meal With Plant Protein Sources in Diets With or Without Jack Mackerel Meal Inclusion on Growth Performance of Red Sea Bream (Pagrus major)

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
Due to stagnant production and high cost of fish meal (FM), feed nutritionists are seeking reliable and affordable alternatives. However, low‐FM diets often result in poor palatability, reduced feed consumption (FC), and impaired growth. This study investigates the effects of replacing FM with plant proteins in diets with or without jack mackerel meal (

Effects of Replacing Fishmeal With Antarctic Krill Meal on Nutrient Deposition, Metabolism, and Immunity in Silver Pomfret (Pampus argenteus)

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
Although silver pomfret (Pampus argenteus) is a highly valued marine fish in China, its aquaculture development is limited by the lack of species‐specific formulated feed. This study investigated the effects of replacing fishmeal with Antarctic krill (Euphausia superba) meal (AKM) on the nutritional deposition, metabolism, and immune response of silver

The complete mitochondrial genome of the ice krill Euphausia crystallorophias Holt & Tattersall, 1906 (Euphausiacea, Euphausiidae), from the Ross Sea, Antarctica

Mitochondrial DNA. Part B. Resources
The mitogenome of Euphausia crystallorophias collected from the Ross Sea Region Marine Protected Area (RSR MPA) is described for the first time. The assembled mitogenome was 17,291 bp in length and consisted of two ribosomal RNAs (rRNAs), 22 transfer ...

De Novo Transcriptome Assembly Reveals Insights Into Osmoregulation and Oxidative Stress Response in the Gills of the Southern King Crab (Lithodes santolla)

Ecology and Evolution, Volume 15, Issue 11, November 2025.
The Southern King Crab (Lithodes santolla), an ecologically and commercially important species in sub‐Antarctic waters. In this study, we assembled the first gill de novo transcriptome of L. santolla to characterize gene expression related to environmental responses.

Effect of body size, temperature and starvation on oxygen consumption of antarctic krill Euphausia superba

Brazilian Journal of Oceanography, 1997
Routine oxygen consumption of krill was investigated as a general measure of its metabolism and assesses the effects of body size, temperature and starvation on the metabolism. No significant difference in whole animal consllmption was detected after 1,3,

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.

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 ...

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)
