Prolactin regulation in the coho salmon,Oncorhynchus kisutch

Journal of Comparative Physiology ? B, 1980
Parr and smolt sea water acclimated coho salmon,Oncorhynchus kisutch were subjected to gradual and direct transfers to fresh water. Plasma osmotic pressure, Na+, K+, Ca++ and Mg++ were similar in freshwater (FW) fish and seawater (SW) transferred controls for the 24 h following transfer.

Purification and characterization of enolases from coho (Oncorhynchus kisutch) and chum (Oncorhynchus keta) salmon

Archives of Biochemistry and Biophysics, 1970
Abstract Enolase from two species of Pacific salmon has been isolated and characterized. Both crystalline preparations show the presence of three electrophoretically distinct enzyme forms, but while the chum salmon enolases appear in an approximate ratio of 1:3:4, the coho salmon has one predominant (95%) form and only traces of two other enolases ...

Coronary blood flow in vivo in the coho salmon (Oncorhynchus kisutch)

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1993
The effects of adrenergic agonists on dorsal aortic blood pressure, cardiac output, and coronary blood flow were studied in unrestrained coho salmon, Oncorhynchus kisutch. Resting coronary blood flow was 0.43 ml.min-1.kg body mass-1, which represented 1.1% of cardiac output or approximately 0.5 ml.min-1.g-1 compact ventricular mass calculated on 40 ...

A genetic linkage map for coho salmon (Oncorhynchus kisutch)

Animal Genetics, 2008
SummaryConstruction of genetic linkage maps is an important first step for a variety of genomic applications, such as selective breeding in aquaculture, comparative studies of chromosomal evolution and identification of loci that have played key roles in the evolution of a species. Here we present a sex‐specific linkage map for coho salmon. The map was

The Embryology of the Coho Salmon, Oncorhynchus kisutch (Walbaum)

Transactions of the American Fisheries Society, 1974
Abstract The early development of the coho salmon, Oncorhynchus kisutch, is similar to that of the chum salmon, Oncorhynchus keta, as already described in the literature. This study of the coho salmon begins at the closure of the blastopore where the work of previous investigators terminates.

The effect of prolactin on calcium homeostasis in coho salmon (Oncorhynchus kisutch)

General and Comparative Endocrinology, 1989
The response of plasma prolactin (PRL) to manipulations of plasma calcium were investigated in coho salmon. Injection of 3.16 mumol EGTA/10 g body weight (to reduce the plasma calcium activity) resulted in significantly higher plasma PRL levels. Lower doses of EGTA (1.06 and 2.13 mumol/10 g body wt) had no effect on plasma PRL concentrations. Injection

Sexual difference in PCB concentrations of coho salmon (Oncorhynchus kisutch)

Science of The Total Environment, 2010
We determined polychlorinated biphenyl (PCB) concentrations in 35 female coho salmon (Oncorhynchus kisutch) and 60 male coho salmon caught in Lake Michigan (Michigan and Wisconsin, United States) during the fall of 1994 and 1995. In addition, we determined PCB concentrations in the skin-on fillets of 26 female and 19 male Lake Michigan coho salmon ...

Olfactory Imprinting in Coho Salmon (Oncorhynchus kisutch)

1978
Taken together, we believe the results of our recent, unified studies provide conclusive evidence for olfactory imprinting. In addition, since our studies were conducted in the field, they provide direct evidence that Coho Salmon retain and use artificial chemical information to achieve successful homing.

Growth hormone and seawater adaptation in coho salmon, Oncorhynchus kisutch

Comparative Biochemistry and Physiology Part A: Physiology, 1987
1. Effects of growth hormone (GH) were examined on short-term aspects of seawater adaptation in coho salmon smolts. 2. Injection of somatostatin (SRIF) immediately prior to seawater entry suppressed plasma GH levels, but did not have any significant effects at 6 or 12 hr on hematocrits, plasma glucose or plasma Na+ levels. 3. Plasma GH levels increased

Uptake and metabolism of lead and cadmium in Coho salmon (oncorhynchus kisutch)

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1979
Abstract 1. Coho salmon exposed to water-borne lead and cadmium accumulated relatively high concentrations of each metal in gills, liver and kidney (primarily the posterior segment). 2. Cadmium concentrations in kidney increased for at least a month after termination of exposure; however, concentrations of lead remained about the same. 3.
