Structure of the urinary bladder in the Pacific cod
Japanese Journal of Ichthyology, 1987The urinary bladder of the Pacific cod,Gadus macrocephalus was investigated. A pair of ureters was found to unite and form a sac-like protrusion on the posteroventral aspect of the gonad. This protrusion was confirmed as the urinary bladder based on its histology and the presence of ammonia and urea in the fluid within this structure.

Embryonic development of the pacific cod Gadus macrocephalus (Gadidae)
Russian Journal of Marine Biology, 2010Incubation of pacific cod eggs was divided into eight series, in which temperatures were set at −0.04°C to +4.03°C and warm and cold conditions alternated. The morphological changes that took place during the embryogenesis were described in detail using the results of the incubation.

Derivation of Pacific Cod Age Composition Using Length-Frequency Analysis
North American Journal of Fisheries Management, 1982Abstract A computer program was developed to estimate age composition from length-frequency samples of Pacific cod (Gadus macrocephalus) landed in British Columbia from Hecate Strait. Age groups were identified by fitting estimates of mean length at age and their standard deviations to the growth pattern determined by results of tagging experiments and

Pacific cod shelf-life experiment report
This report on the Pacific cod shelf-life experiment compares two methods of handling and preserving fish quality aboard fishing vessels: the traditional Kaia Fisheries method using refrigerated seawater tank onboard (RSW-OLD) and a new slurry ice method using plastic tubs for storage (SLURRY-NEW).Elíasson, Sæmundur +1 more

Consumption, growth and evacuation in the Pacific cod, Gadus macrocephalus
Journal of Fish Biology, 1990Growth of Pacific cod was related to energy consumption (cal g−1 day−1) and was well described by linear equations. Maintenance ration was 11 and 12 cal g−1 day−1 at 4.5 and 6.5° C, respectively. Cod between 200 and 5000 g had similar growth rates when growth was expressed as a function of consumption (cal g−1 day−1).

Molecular characterization of Anisakis pegreffii larvae in Pacific cod in Japan
Journal of Helminthology, 2005AbstractIt is now recognized that the morphospecies Anisakis simplex is not a single species but a complex composed of three sibling species, A. simplex sensu stricto, A. pegreffii and A. simplex C. In Japan, A. simplex-like larvae have been isolated from a variety of fish and humans, but the larvae collected have been identified as A.

Elevated CO2 alters behavior, growth, and lipid composition of Pacific cod larvae
Marine Environmental Research, 2019High-latitude seas, which support a number of commercially important fisheries, are predicted to be most immediately impacted by ongoing ocean acidification (OA). Elevated CO2 levels have been shown to induce a range of impacts on the physiology and behavior of marine fish larvae.

Oxidative deterioration of flesh lipids of pacific cod(Gadus macrocephalus)
Journal of the American Oil Chemists' Society, 1967AbstractLight flesh lipids of Pacific cod, composed chiefly of phosphatidyl ethanolamine and phosphatidyl choline, contain fatty acids rich in unsaturation. In model systems free of pro‐oxidant the ethanolamine derivative exhibited a high rate of oxidation.

Diel vertical migration of adult Pacific cod Gadus macrocephalus in Alaska
Journal of Fish Biology, 2013The diel vertical migration (DVM) of Pacific cod Gadus macrocephalus was examined using depth and temperature data from 250 recaptured archival tags deployed on G. macrocephalus in the eastern Bering Sea and in the Gulf of Alaska near Kodiak Island.

Multiple ice-age refugia in Pacific cod, Gadus macrocephalus.
Molecular ecology, 2014Pleistocene ice-ages greatly influenced the historical abundances of Pacific cod, Gadus macrocephalus, in the North Pacific and its marginal seas. We surveyed genetic variation at 11 microsatellite loci and mitochondrial (mt) DNA in samples from twelve locations from the Sea of Japan to Washington State.
