Bioenergetics of Arctic cod (Boreogadus saida) at low temperatures

Canadian Journal of Fisheries and Aquatic Sciences, 1997
The 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, 1985
1. 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′

Biomarker responses in polar cod (Boreogadus saida) exposed to dietary crude oil

Aquatic Toxicology, 2010
Polar cod Boreogadus saida were exposed weekly to two doses of dietary crude oil for 4 weeks followed by 2 weeks of depuration. Administered doses corresponded on average to 4 and 9microgSigmaPAHsg(-1)fishweek(-1). Cytochrome P4501A1 (cyp1a1) and glutathione S-transferase (gst) mRNA expression, ethoxyresorufin O-deethylase (EROD) activity and ...

Quantitative analysis of the polar cod (Boreogadus saida) hepatic proteome highlights interconnected responses in cellular adaptation and defence mechanisms after dietary benzo[a]pyrene exposure.

Science of the Total Environment
Increased industrial offshore activities in northern waters raise the question of impact of polycyclic aromatic hydrocarbons (PAHs) on key Arctic marine species.

Ichthyoplankton of Russian Arctic Seas: 1. Polar cod Boreogadus saida

Journal of Ichthyology, 2018
The information on the size composition and distribution of the larvae and juveniles of polar cod Boreogadus saida on the shelf of Russian Arctic seas (the Kara Sea, the Laptev Sea, and the East Siberian Sea) is presented for the period of July–September 2015–2017.

Tracking gonadal development in fish: An in vivo MRI study on polar cod, Boreogadus saida (Lepechin, 1774)

NMR in Biomedicine
Magnetic resonance imaging (MRI) was applied to determine the sex of polar cod (Boreogadus saida Lepechin, 1774) (Actinopterygii: Gadidae) and to follow the gonadal development in individual animals over time.

Multiple exposure of the Boreogadus saida from bessel fjord (NE Greenland) to legacy and emerging pollutants

Chemosphere, 2021
This work investigates the occurrence of OCPs, such as hexachlorocyclohexane (α-, β-, γ- and δ-HCH) isomers, dichlorodiphenyltrichloroethane (p,p'-DDT) and its metabolite dichlorodiphenyldichloroethylene (p,p'-DDE), endosulfan (α- and β-EDS) isomers, chlorpyrifos (CPF), dacthal (DAC) and phenolic compounds, such as 4-nonylphenol (4-NP) and its ...

PAH biomarker responses in polar cod (Boreogadus saida) exposed to benzo(a)pyrene

Aquatic Toxicology, 2009
With expanding oil and gas activities into the Arctic region, there is a need to evaluate the induction capacity of polycyclic aromatic hydrocarbon (PAH) biomarkers on Arctic marine organisms and to test analytical methods that have been optimized for their temperate counterparts.

Feeding of Polar cod Boreogadus saida in the Kara Sea

Journal of Ichthyology, 2017
In 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.

Population Genetic Diversity of Arctic Cod (Boreogadus saida) of Russian Arctic Seas

Journal of Ichthyology, 2019
We present the data on genetic variation of Arctic cod Boreogadus saida assessed using seven microsatellite loci in four samples collected in the Kara, Laptev, and East-Siberian seas in 2014 and 2017. We found small but mostly statistically significant differences between the samples.
