claimIn the eastern Barents Sea, polar cod (Arctogadus glacialis) migrate northward in May and June following the ice edge, with the largest fish migrating first.

claimArctic cod (Boreogadus saida) and polar cod (Arctogadus glacialis) are important forage fishes for predators in Arctic and Subarctic regions.

referenceForster, C. E., Norcross, B. L., Mueter, F. J., Logerwell, E. A., and Seitz, A. C. (2020) published 'Spatial patterns, environmental correlates, and potential seasonal migration triangle of polar cod (Boreogadus saida) distribution in the Chukchi and Beaufort seas' in Polar Biology, volume 43, pages 1073–1094, analyzing the migration patterns of polar cod.

referencePolar cod (Boreogadus saida) and capelin (Mallotus villosus) serve as key species in the marine food webs of the Arctic and the Barents Sea, as described in a 2013 study by Hop and Gjøsæter.

claimSaffron cod (Eleginus gracilis) are more demersal than Arctic cod (Boreogadus saida) and polar cod (Arctogadus glacialis), and they maintain a more southerly and nearshore distribution.

referenceBenoit et al. (2010) studied the influence of photoperiod, seal predation, and landfast ice on the diel vertical migrations of polar cod (Boreogadus saida) in the Arctic Ocean.

referenceGeoffroy et al. (2011) documented the aggregation of polar cod (Boreogadus saida) in the deep Atlantic layer of the ice-covered Amundsen Gulf in the Beaufort Sea during winter.

claimPolar cod egg and larval drift patterns in the Svalbard archipelago were studied by Eriksen et al. in 2020.

referenceMcNicholl et al. (2018) analyzed the isotopic niche overlap between co-occurring capelin (Mallotus villosus) and polar cod (Boreogadus saida), while also examining how lipid extraction affects stable isotope ratios.

measurementAdult polar cod (Arctogadus glacialis) may perform long seasonal movements of less than 200 kilometers within the Arctic.

claimPolar cod (Arctogadus glacialis) move between inshore and offshore areas in relation to spawning, feeding, and juvenile development.

referenceBenoit et al. (2014) characterized the pre-winter distribution and habitat of polar cod (Boreogadus saida) in the southeastern Beaufort Sea.
