Mitochondrial acclimation potential to ocean acidification and warming of Polar cod (Boreogadus saida) and Atlantic cod (Gadus morhua) [PDF]
Frontiers in Zoology, 2017 Background Ocean acidification and warming are happening fast in the Arctic but little is known about the effects of ocean acidification and warming on the physiological performance and survival of Arctic fish.

Polar cod in jeopardy under the retreating Arctic sea ice. [PDF]
Commun Biol, 2019 AbstractThe Arctic amplification of global warming is causing the Arctic-Atlantic ice edge to retreat at unprecedented rates. Here we show how variability and change in sea ice cover in the Barents Sea, the largest shelf sea of the Arctic, affect the population dynamics of a keystone species of the ice-associated food web, the polar cod (Boreogadus ...

The physiological response of the Arctic key species Polar cod, Boreogadus saida, to hypoxia in a warming ocean: critical oxygen levels and swimming performance [PDF]
BMC ZoologyGlobal warming has already caused a loss of nearly 50% Arctic sea-ice coverage since the 1980s. This sea-ice loss strengthens summer stratification of the ocean’s water column and, consequently, hypoxic zones may form in the deep-water layers.

Plastic ingestion by juvenile polar cod (Boreogadus saida) in the Arctic Ocean. [PDF]
Polar Biol, 2018 One of the recently recognised stressors in Arctic ecosystems concerns plastic litter. In this study, juvenile polar cod (Boreogadus saida) were investigated for the presence of plastics in their stomachs. Polar cod is considered a key species in the Arctic ecosystem.

The importance of Calanus glacialis for the feeding success of young polar cod: a circumpolar synthesis. [PDF]
Polar Biol, 2020 AbstractUnderstanding the feeding ecology of polar cod (Boreogadus saida) during its first year of life is crucial to forecasting its response to the ongoing borealization of Arctic seas. We investigated the relationships between diet composition and feeding success in 1797 polar cod larvae and juveniles 4.5–55.6 mm standard length (SL) collected in ...

Rapid genome modifications including chromosomal fusions and large-scale inversions are key features in Arctic codfish species [PDF]
Genome BiologyBackground Genome evolvability involves activation of transposable elements (TEs) that result in novel genomic rearrangements, including translocations, deletions, duplications, as well as larger structural reorganizations, such as chromosomal inversions

Gastrointestinal evacuation of particulate matter in polar cod Boreogadus saida [PDF]
Marine Ecology - Progress Series, 1999 Gastrointestinal evacuation of inert particles was monitored in the polar cod Boreogadus saida (Lepechin), held at a temperature of 0.5°C. Fish (31.8 g ± 0.8 SD) were fed a moist diet, based on natural prey items, containing a particulate marker. Evacuation of marker from the gastrointestinal tract started 48 h after ingestion of a meal.
