Cardiac arrest in the spawning chum salmon

Comparative Biochemistry and Physiology Part A: Physiology, 1983
1. Cardiac activities of male and female spawning chum salmon were recorded simultaneously by using a radio telemetry system in combination with a wired system. 2. Heart beat stopped during a spawning bout for about 10 sec in female and for 4-6 sec in male. 3. Just before and after the temporary cardiac arrest, heart rate increased from the usual rate,

Assignment of Disulfide Linkages in Chum Salmon Stanniocalcin

Biochemical and Biophysical Research Communications, 1999
Stanniocalcin (STC) is a hypocalcemic glycoprotein hormone secreted by the corpuscles of Stannius, endocrine glands unique to the bony fishes. Recently, two cDNAs encoding proteins, STC-1 and STC-2, homologous to fish STC have been identified in humans and rodents.

Isolation and characterization of chum salmon growth hormone

Archives of Biochemistry and Biophysics, 1986
Two molecular forms of salmon growth hormone (sGH), sGH I and II, have been isolated from the pituitary glands of the chum salmon (Oncorhynchus keta); a two-step extraction procedure, under alkaline (pH 10) conditions, subsequent to acid-acetone extraction was employed for extraction of the sGHs. They were then purified by iso-electric precipitation at

Cysteine Protease Inhibitor in Egg of Chum Salmon

The Journal of Biochemistry, 1991
Two different cysteine protease inhibitors (Forms I and II) were isolated from chum salmon egg, and their molecular weights were found to be 16,000 and 11,000, respectively. When the N-terminal amino acid sequences of Forms I and II were compared, 67% of the residues were identical but no apparent homology was found between these inhibitors and ...

Gene mapping of isozyme loci in chum salmon

Journal of Heredity, 1986
Recombination values were used to calculate the gene-centromere map distances for four electrophoretically detected loci, Aat3, Idh1, Idh4, and Mpi, in chum salmon (Oncorhynchus keta). We also report the results from 39 pairwise examinations for joint segregation for 10 loci in nine testcross families. Only two loci assorted nonrandomly--either Aat1 or

DNA homologies between the rainbow trout, chum salmon and coho salmon

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1985
The thermal stabilities of hybrid duplexes between the DNAs from three salmonid fish species were monitored as measures of DNA homology. The chum salmon, Oncorhynchus keta, and coho salmon, Oncorhynchus kisutch, had more DNA homology with each other than either had with the rainbow trout, Salmo gairdnerii.

Microelement composition of pink salmon (Pink Salmon) and chum salmon (Chum Salmon) in the period of early ontogenesis

Fisheries
The content of Fe, Zn, Cu, Ni, Cd, Pb, and Mn in fertilized caviar, pink salmon and chum salmon larvae and larvae from three fish hatcheries in the Sakhalin region before feeding, as well as in chum salmon larvae from spawning mounds from natural spawning grounds, was studied; the microelement composition of zygotes was compared with the gametes of ...

Microsatellite variability in chum salmon of Primorye

Russian Journal of Genetics, 2017
In this study, 12 samples of chum salmon from the southern and central parts of Primorye were studied with ten microsatellite loci. All studied localities of chum salmon of Primorye formed three main genetically different groups: (1) the Narva–Barabashevka–Ryazanovka cluster of southern Primorye, (2) Kievka River, and (3) Avvakumovka River.

Characterization of melanin-concentrating hormone in chum salmon pituitaries

Nature, 1983
Many lower vertebrates exhibit colour change in response to the background. A dual hormonal control of colour change by two antagonistic pituitary melanophorotropic hormones was first postulated in amphibia by Hogben and Slome. It is well established that the melanotropins alpha- and beta-MSH are responsible for pigment dispersion in the integumentary ...

A radioimmunoassay for N-terminal peptide of chum salmon proopiocortin

Fish Physiology and Biochemistry, 1987
A highly specific radioimmunoassay was developed for N-terminal peptide of salmonid proopiocortin using a guinea pig antiserum to the chum salmon peptide (sNPP 1). Since sNPP I has no tyrosine residue nor free N-terminal amino group, a mixture of minor components of sNPP 1, which have extensions of H-Val-LysGly- and H-Lys-Gly- at the N-terminus, were ...
