Polar cod Boreogadus saida occurrence is driven by temperature at the margin of its distribution
Journal of Fish BiologyAbstract With a warming Arctic, suitable habitat for polar cod Boreogadus saida (Lepechin 1774) is predicted to decrease. We investigated the changes in distribution of polar cod on the southern limit of its distribution in the Atlantic Ocean (around Iceland) during both autumn and spring after a recent period of warming in the area.

Circumpolar genetic population structure of polar cod, Boreogadus saida
Polar Biology, 2020Polar cod, Boreogadus saida, is an important part of Arctic and boreal marine ecosystems. Knowledge of polar cod population genetic structuring can provide insight into how the species may respond to environmental change, and allow for establishment of meaningful management units. To examine population genetic structure of B.

Feeding of Polar cod Boreogadus saida in the Kara Sea
Journal of Ichthyology, 2017In the summer–autumn period of 2007, 2010, and 2013, the peculiarities of Polar cod feeding Boreogadus saida in the Kara Sea were considered. In these years, the intensity of feeding of adult individuals was quite similar. Spatial and interannual differences in the composition of the food have been observed.

A transcriptome resource for the Arctic Cod (Boreogadus saida)
Marine Genomics, 2018Abstract Arctic Cod (Boreogadus saida) serve as an important link in Arctic food webs and are thus considered an important species for environmental monitoring. RNA-Seq was conducted on samples from wild-collected individuals representing various age classes and tissue types to obtain as complete a transcriptome as possible on an Illumina MiSeq ...

Population Structure and Growth of Polar Cod Boreogadus saida in the Sea of Laptev
Journal of Ichthyology, 2021The population structure and growth rate of polar cod Boreogadus saida in the Laptev Sea are analyzed based on the materials collected in the summer–autumn period of 2014. The catches included individuals with lengths of 3.5–28.5 cm and a weight of 0.6–129.0 g at ages 0+ to 7+.

Bioenergetics of Arctic cod (Boreogadus saida) at low temperatures
Canadian Journal of Fisheries and Aquatic Sciences, 1997The Arctic cod (Boreogadus saida), a key component of the marine food web of Canadian high Arctic waters, occurs at temperatures close to or below zero. We established a complete energy budget for this Arctic fish, based on laboratory measurements of consumption (C), growth (G), respiration (R), egestion (F), and excretion (U) at about 0°C. An average (

Isolation and characterization of pepsin from polar cod (Boreogadus saida)
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19851. 1. Two zymogens of pepsin, pepsinogens A and B, were isolated from the gastric mucosa from Polar cod. Pepsins A and B accounted for more than 90% of the total pepsin units obtained in the crude extract of the mucosa. 2. 2. Pepsinogen A had a mol. wt of 42,000 and a P1 of 3.75. With hemoglobin as substrate, pepsin A had pH optimum of 2.0, a Km′
