Gastrointestinal evacuation of particulate matter in polar cod Boreogadus saida [PDF]
Marine Ecology - Progress Series, 1999 Gastrointestinal evacuation of inert particles was monitored in the polar cod Boreogadus saida (Lepechin), held at a temperature of 0.5°C. Fish (31.8 g ± 0.8 SD) were fed a moist diet, based on natural prey items, containing a particulate marker. Evacuation of marker from the gastrointestinal tract started 48 h after ingestion of a meal.

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+.

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.

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 (

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.

Impact of dispersed fuel oil on cardiac mitochondrial function in polar cod Boreogadus saida
Environmental Science and Pollution Research, 2014 In this study, impact of dispersed oil on cardiac mitochondrial function was assessed in a key species of Arctic marine ecosystem, the polar cod Boreogadus saida. Mature polar cod were exposed during 48 h to dispersed oil (mechanically and chemically) and dispersants alone.

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′

Biomarker responses in polar cod (Boreogadus saida) exposed to dietary crude oil
Aquatic Toxicology, 2010Polar 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 ...
