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 ...

Oceanic swarms of Antarctic krill perform satiation sinking [PDF]
Antarctic krill form some of the highest concentrations of animal biomass observed in the world's oceans potentially due to their prolific ability to swarm. Determining the movement of Antarctic krill within swarms is important to identify drivers of their behaviour and their biogeochemical impact on their environment. We examined vertical

ABSTRACT Passive acoustic monitoring is a cost‐effective means of studying marine mammals that inhabit remote and poorly accessible habitats. Since the 1970s, the mysterious “bio‐duck” sound has been reported throughout the Southern Ocean. In 2014, this was attributed to the Antarctic minke whale and has since been retrospectively categorized into ...

Seawater acidification more than warming presents a challenge for two Antarctic macroalgal-associated amphipods [PDF]
Elevated atmospheric pCO2 concentrations are triggering seawater pH reductions and seawater temperature increases along the western Antarctic Peninsula (WAP).

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 (

Restricted regions of enhanced growth of Antarctic krill in the circumpolar Southern Ocean [PDF]
Food webs in high-latitude oceans are dominated by relatively few species. Future ocean and sea-ice changes affecting the distribution of such species will impact the structure and functioning of whole ecosystems. Antarctic krill (Euphausia superba) is a

Improved parametrization of Antarctic krill target strength models [PDF]
There are historical discrepancies between empirical observations of Antarctic krill target strength and predictions using theoretical scattering models. These differences are addressed through improved understanding of key model parameters. The scattering process was modeled using the distorted-wave Born approximation, representing the shape of the ...

Abstract Southern Ocean phytoplankton have unique traits that allow them to survive extreme environmental conditions of low iron, light, and temperature. These traits are not well represented in Earth System Models and may lead to misrepresentation of the bloom seasonal cycle in this critical oceanic region.

The potential role of Antarctic krill faecal pellets in efficient carbon export at the marginal ice zone of the South Orkney Islands in spring [PDF]
Antarctic krill (Euphausia superba) play a central role in the food web of the Southern Ocean, forming a link between primary production and large predators.
