Lack of Genetic Stock Discretion in Pacific Cod (Gadus macrocephalus)
Canadian Journal of Fisheries and Aquatic Sciences, 1987We examined the ocean-wide genetic population structure of Pacific cod (Gadus macrocephalus) using electrophoretically detectable population markers at 41 protein loci. Samples were collected at 11 locations extending over most of the species's range from the Yellow Sea, Korea, to Puget Sound, Washington.

The variability of the Gmo3, Gmo34, Gmo35, Pgmo32, Gmo19 microsatellite DNA loci was examined in the population samples of Pacific cod from different parts of the North Pacific. The statistical tests showed that the differentiation of the population was the result of different levels of reproductive autonomy of the individual Pacific cod populations ...

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.

Miltpain (EC.3.4.22.-) is a cysteine proteinase that preferentially hydrolyzes basic proteins, previously found in the milt of chum salmon. Here we report a similar cysteine proteinase in the milt of the marine Pacific cod. The enzyme was isolated and purified 6900-fold and with an estimated mass of 63 kDa by gel filtration chromatography and 72 kDa by

Archives of Virology, 2015
A mortality rate higher than 90% was observed in a larva-rearing facility for Pacific cod, Gadus macrocephalus, in China. Larvae showing clinical signs of infection were collected. Initial suspicion of nervous necrosis virus (NNV) infection was confirmed by sequencing, absolute quantification real-time PCR (A-qPCR), and electron microscopy.

Investigation of weight loss in Pacific cod (Gadus macrocephalus) due to exsanguination.
2011Pacific cod (Gadus macrocephalus) are an important groundfish species harvested by longline vessels in the Bering Sea and Aleutian Islands. Exsanguination, or bleeding, is an important processing step at the time of capture to obtain high product quality, including freshness and the visual appearance of fillets.

Laboratory‐validated data on the survival, development and hatching responses of fertilized Pacific cod Gadus macrocephalus eggs from the northern Japan stock were determined through an incubation experiment. The optimum temperature for survival until hatching ranged from 4 to 8° C.

Abstract Walleye pollock ( Gadus chalcogrammus ) and Pacific cod ( Gadus macrocephalus ) are of particular economic and ecological importance in the southeastern Bering Sea. The spatial and temporal overlap of early life stages of both species may explain their strongly correlated recruitment trends. Pelagic larvae and juveniles were collected during

Environmental confirmation of multiple ice age refugia for Pacific cod, Gadus macrocephalus
Evolutionary Ecology, 2013The concept of species surviving through quaternary climatic extremes by retreating to glacial refugia, and then evolving genetically during re-population movements of the following interglacial, has been in the literature for over 40 years. Recently, advances in genetic analysis have enabled this concept to be validated and theories regarding ...

Delineating management units for Pacific cod (Gadus macrocephalus) in the Sea of Japan
Estuarine, Coastal and Shelf Science, 2019Abstract Advances in population genetics have brought about the use of management units (MUs) for the assessment and management of marine resources. Some marine species with an apparently continuous distribution actually have local genetically distinct populations across their range, so careful consideration is required in the delineation of MUs.
