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.

Molecular Cloning and Gene Expression of Chum Salmon Cystatin

Journal of Biochemistry, 1996
A salmon cystatin cDNA clone was isolated from a chum salmon cDNA library. The clone encoded a full-length extracellular-type cystatin and its signal peptide and included 5'- and 3'-untranslated regions. The deduced amino acid sequence showed a high degree of sequence similarity to mammalian cystatin C, chicken egg cystatin, and chum salmon pituitary ...

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 ...

Cryopreservation of chum salmon blastomeres by the straw method

Cryobiology, 2002
In order to preserve genetic resources of chum salmon, Oncorhynchus keta, optimum conditions for cryopreservation of isolated blastomeres were investigated. Survival rates under various conditions were compared: the nature and the concentration of cryoprotectants before and after freezing, the seeding temperature, and the developmental stages of donor ...

Chum salmon pituitary fractions: Somatotropic activity and cytoimmunofluorescence studies

General and Comparative Endocrinology, 1979
Abstract Highly purified chum salmon pituitary fractions were bioassayed for their ability to stimulate elongation in hypophysectomized rainbow trout, Salmo gairdneri . One fraction, previously identified as the Na-retaining principle, prolactin, was not active. Of the active fractions, only the most potent one elicited a dose response. An antiserum

An Improved Sibling Model for Forecasting Chum Salmon and Sockeye Salmon Abundance

North American Journal of Fisheries Management, 2007
Abstract The sibling model is often one of the best methods for calculating preseason forecasts of adult return abundance (recruits) for populations of Pacific salmon Oncorhynchus spp. This model forecasts abundance of a given age-class for a given year based on the abundance of the previous age-class in the previous year.

Vertebral Abnormalities in Sockeye, Pink, and Chum Salmon

Transactions of the American Fisheries Society, 1966
Abstract Radiographs of vertebral structures of 10,377 sockeye, 4,403 chum, and 4,777 pink salmon collected in 1958 to 1962 were examined to determine the frequency of occurrence of abnormal vertebrae in wild populations of mature Pacific salmon. Various types of deviations from the orderly processes of development or segmentation that resulted in ...

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 ...

Marking Chum Salmon Fry Vertebrae with Oxytetracycline

North American Journal of Fisheries Management, 1986
Abstract An experiment was conducted to determine the effectiveness of oxytetracycline (OTC) as a method of marking chum salmon (Oncorhynchus keta) fry vertebrae. Three groups of fry that originated from a gravel box incubation system and three groups that originated from a Japanese-style (channel) incubation system were treated with an OTC-Oregon ...

Effects of hatchery chum salmon fry on density-dependent intra- and interspecific competition between wild chum and masu salmon fry

Canadian Journal of Fisheries and Aquatic Sciences, 2014
Stocking with hatchery fish is the principal method for harvest augmentation and, recently, restoring endangered populations. However, there is increasing concern about the negative effects of competition between hatchery and wild fish. In this study, enclosure experiments were conducted to evaluate the effects of hatchery chum salmon fry ...
