Effects of chronic crude oil exposure on the fitness of polar cod (Boreogadus saida) through changes in growth, energy reserves and survival.

Marine Environmental Research, 2021
Climate models predict extended periods with sea-ice free Arctic waters during the next decade, which will allow more shipping activity and easier access to petroleum resources.

Antioxidant defenses in polar cod (Boreogadus saida) and responsiveness toward dietary crude oil exposure [PDF]

Marine Environmental Research, 2017
Increasing anthropogenic activities in the Arctic pose the risk for accidental oil spills but our knowledge of ecotoxicological effects is still limited for Arctic organisms. This study aimed to provide insights in baseline levels of antioxidants in polar cod (Boreogadus saida) from different Arctic locations and investigate the susceptibility of this ...

Decline and northward shift in Arctic cod distribution associated with the changing climate around Greenland

Arctic Science
Arctic cod (Boreogadus saida Lepechin, 1774) is a key species in Arctic marine ecosystems, acting as a dominant mid-trophic link that transfers up to 75% of energy to higher trophic levels. It is therefore central to cultural identity, ecosystem function,

Aspects of growth in Arctic cod, Boreogadus saida (Lepechin 1773)

Polar Research, 1991
In June 1986- 42 young Arctic cod were caught in ice-covered waters of the Barents sea with dip-nets by scuba divers. From August to June 1987 the fish were kept at -PC and fed on frozen shrimp (Pandalus borealis). Length and weight were measured monthly. A fast weight increment of about 0.7% per day was observed in the autumn (Sept.-Nov.).

Insights into the diet and feeding behavior of immature polar cod (Boreogadus saida) from the under-ice habitat of the central Arctic Ocean.

Journal of Fish Biology
Polar cod (Boreogadus saida) is an endemic key species of the Arctic Ocean ecosystem. The ecology of this forage fish is well studied in Arctic shelf habitats where a large part of its population lives. However, knowledge about its ecology in the central

The co-distribution of Arctic cod and its seabird predators across the marginal ice zone in Baffin Bay

Elementa: Science of the Anthropocene, 2019
Arctic cod ('Boreogadus saida') is the dominant pelagic fish in Arctic seas and a staple food of many arctic predators including several seabird species. Marginal ice zones are known as important feeding locations for seabirds.
