Hepatic Transcriptomic Responsiveness of Polar Cod, Boreogadus saida, to Ocean Acidification and Warming

Fishes
Background: This study was part of a larger comprehensive project (BIOACID) addressing the physiological resilience of Polar cod, Boreogadus saida, to ocean acidification and global warming and aimed to unravel underlying molecular mechanisms of the ...

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.

Susceptibility of polar cod (Boreogadus saida) to a model carcinogen [PDF]

Marine Environmental Research, 2021
Studies that aim to characterise the susceptibility of the ecologically relevant and non-model fish polar cod (Boreogadus saida) to model carcinogens are required. Polar cod were exposed under laboratory conditions for six months to control, 0.03 μg BaP/g fish/week and 0.3 μg BaP/g fish/week dietary benzo(a)pyrene (BaP), a reference carcinogen.

Sounds of Arctic cod (Boreogadus saida) in captivity: A preliminary description [PDF]

The Journal of the Acoustical Society of America, 2018
Sounds produced by Arctic cod were recorded for the first time and suggest passive acoustic monitoring (PAM) can be an effective additional tool for the study and management of the species. Each of the 38 calls detected in three different aquatic facilities consisted of a single grunt with 6 to 12 pulses and a mean duration of 289 ms.

Dysregulation of microRNAs may contribute to neurosensory impairment in Arctic cod (Boreogadus saida) following CO2 exposure

Frontiers in Marine Science, 2023
MicroRNAs (miRNAs) are epigenetic markers with a key role in post-transcriptional gene regulation. Several studies have described the dysregulation of miRNAs in temperature and hypoxic stress responses of marine organisms, but their role in the response ...

Size class segregation of Arctic cod (Boreogadus saida) in a shallow High Arctic embayment

Arctic Science, 2021
Arctic cod (Boreogadus saida (Lepechin, 1774)) vertically segregate by size class in deep waters, but such dynamics had not been explored in shallow waters.

Arctic cod (Boreogadus saida) in fjord and glacial habitats: a collaborative study with Uummannap Kangerlua fishers

Arctic Science, 2023
Arctic cod (Boreogadus saida) (Lepechin, 1774) is often found in front of glaciers, which is the least studied of the species’ habitats. Uummannap Kangerlua and Sullorsuaq in West Greenland provide a unique opportunity to study Arctic cod in the glacial ...

Top-Down and Bottom-Up Processes Jointly Explain Mesopredator Movement and Foraging Ecology. [PDF]

Ecol Lett
This study integrates top‐down (polar bear habitat selection) and bottom‐up (fish distribution) processes to test how mesopredators (ringed seals) balance risk–reward tradeoffs in habitat selection. Ringed seals reduced their space use and foraging time in response to predation risk, yet accepted higher risk when prey diversity was elevated ...

Boreogadus saida

, 2021
Boreogadus saida (Lepechin, 1774). Arctic Cod or Polar Cod. To 46 cm (18.1 in) TL (Wienerroither et al. 2011), usually less than 25 cm (9.8 in) (Cohen in Cohen et al. 1990). The largest we know of from our area is a specimen from the Chukchi Sea measuring 30 cm (12 in) TL (Alverson and Wilimovsky 1966). Circumpolar in Arctic (Cohen in Cohen et al. 1990)

Trends in Aquatic Environmental DNA Research in Alaska. [PDF]

Ecol Evol
Environmental DNA (eDNA) analysis is an emerging tool with significant potential to advance biomonitoring, particularly in remote and logistically challenging environments. To evaluate the state of eDNA research in Alaska, we conducted a literature review and a regional survey and results provide the first comprehensive overview of eDNA research in ...
