Evaluation of Antarctic krill (Euphausia superba) meal supplementation in diets for olive flounder (Paralichthys olivaceus)

, 2020
The supplemental effect of Antarctic krill meal (KM) into a low fish meal (FM) diet was evaluated for olive flounder (Paralichthys olivaceus). A 56% FM‐based diet was regarded as a high FM inclusion diet (HFM), and a low‐FM diet (LFM) was prepared by ...

Dissolved and Particulate Methylated Mercury in a Highly Productive Area of the Southern Ocean

Global Biogeochemical Cycles, Volume 40, Issue 1, January 2026.
Abstract Methylated mercury (MeHg), including dimethylmercury and monomethylmercury (MMHg), is a pollutant of concern because it biomagnifies in marine biota. The formation of MeHg in the oceans, specifically at highly productive regions and at high oxygen levels, remains elusive.

Summer Diet of Humpback Whales in the Northern Strait of Georgia, British Columbia (Canada), Revealed by Stable Isotope Analysis

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT North Pacific humpback whales (Megaptera novaeangliae) have recovered rapidly following their depletion by commercial whaling. Diet studies are necessary to assess food web implications of their recovery. This study investigates the diet composition of humpback whales foraging in the northern Strait of Georgia, British Columbia, Canada, an ...

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 (

Quantifying the Escape Mortality of Trawl Caught Antarctic Krill (Euphausia superba). [PDF]

PLoS ONE, 2016
Antarctic krill (Euphausia superba) is an abundant fishery resource, the harvest levels of which are expected to increase. However, many of the length classes of krill can escape through commonly used commercial trawl mesh sizes. A vital component of the

The Biodiversity of Peter I Island—The Most Remote Island in the World

Ecology and Evolution, Volume 15, Issue 11, November 2025.
Peter I Island is one of the most isolated and least visited islands on earth; lying within the Antarctic Polar Front but over 420 km from continental Antarctica. Here we assess the biodiversity of the island from both previous records and our own BioBlitz in January 2022.

Evidence for a decline in the population density of Antarctic krill Euphausia superba Dana, 1850 still stands. A comment on Cox et al

Journal of Crustacean Biology, 2019
Antarctic krill ( Euphausia superba Dana, 1850) exemplifies the key role of marine crustaceans in fisheries, foodwebs, and biogeochemical cycles. Ecological understanding and policy decisions require information on population trends.

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.

Cohort tracking using size‐frequency population survey data to estimate individual growth

Ecosphere, Volume 16, Issue 10, October 2025.
Abstract The relationship between a species' growth rate and its size—its growth function—represents essential biological information for supporting sustainable fisheries and wildlife management. Yet, growth functions are known for only a fraction of species. Progress is especially limited in marine invertebrates, including shellfish, due to challenges
