Gender specific reproductive strategies of an arctic key species (Boreogadus saida) and implications of climate change. [PDF]

open access: yesPLoS ONE, 2014
The Arctic climate is changing at an unprecedented rate. What consequences this may have on the Arctic marine ecosystem depends to a large degree on how its species will respond both directly to elevated temperatures and more indirectly through ...

Seasonal shifts in feeding patterns: Individual and population realized specialization in a high Arctic fish

open access: yesEcology and Evolution, 2019
Species with a broad and flexible diet may be at an advantage in a rapidly changing environment such as in today's Arctic ecosystems. Polar cod (Boreogadus saida), an abundant and ecologically important circumpolar Arctic fish, is often described as a ...

Diet of the ringed seal (Phoca hispida) in Greenland

open access: yesNAMMCO Scientific Publications, 1998
Analysis of 454 stomachs of ringed seals (Phoca hispida) collected from the Inuit hunt in six municipalities in West Greenland and 30 alimentary tracts collected by scientists in East Greenland, showed seasonal and regional differences in the diet.

Morphology of Arctic cod (Boreogadus saida) assessed according to habitat preference and age in the Beaufort Sea

open access: yesArctic Science, 2023
The Arctic cod (Boreogadus saida (Lepechin, 1774)) represents the most widespread and abundant fish in the Arctic and is a critical trophic link in its ecosystems.

Polar cod egg and larval drift patterns in the Svalbard archipelago [PDF]

open access: yesPolar Biology, 2019
AbstractSpawning of polar cod (Boreogadus saida) in the vicinity of the Svalbard archipelago has not been directly observed. From the distribution pattern of polar cod 0-group observed during annual monitoring of the Barents Sea, it has, however, been inferred that spawning occurs in Svalbard waters most years.

Shallow-Water Scavengers of Polar Night and Day – An Arctic Time-Lapse Photography Study

open access: yesFrontiers in Marine Science, 2021
Until recently, polar night constituted truly a “mare incognitum” of our times. Yet, the first records from this very little-explored period showcased a surprisingly rich and active ecosystem.

Climate warming enhances polar cod recruitment, at least transiently [PDF]

open access: yesProgress in Oceanography, 2017
Abstract Polar cod ( Boreogadus saida ) is the dominant forage fish in Arctic seas and the main prey of the ringed seal ( Pusa hispida ), the beluga ( Delphinapterus leucas ) and several seabird species. Changes in the abundance of polar cod will have cascading effects on arctic marine ecosystems.

Age, growth rate, and otolith growth of polar cod (Boreogadus saida) in two fjords of Svalbard, Kongsfjorden and Rijpfjorden

open access: yesOceanologia, 2017
This work presents biological information for polar cod (Boreogadus saida) collected with a Campelen 1800 shrimp bottom trawl in Kongsfjorden (two stations located in the inner part of the fjord adjacent to the glacier) and Rijpfjorden (one station at ...

Can vertical separation of species in trawls be utilized to reduce bycatch in shrimp fisheries?

open access: yesPLoS ONE, 2021
Several shrimp trawl fisheries use a Nordmöre sorting grid to avoid bycatch of fish. However, small fish can pass through the grid. Therefore, the retention of juvenile fish often remains an issue during shrimp trawling.
