Plasma cortisol elevation, a common consequence of stress, occurs in salmonids of
subordinate rank; these fish acquire a smaller share of available food and grow more slowly …

Hypo‐osmoregulatory ability in juvenile Atlantic salmon, Sulrno salur L., was improved by
cortisol treatment. Implantation of a vegetable shortening pellet containing cortisol (50 mg …

In studying the whole-body response of chinook salmon (Oncorhynchus tshawytscha) to
various stressors, we found that 5-hour exposure to elevated temperature (mean 21.6° C;+ …

Atlantic killifish, Fundulus heteroclitus, are intertidal marsh fish found along the east coast of
North America. Associated with the thermal gradient along this coast, northern and southern …

We investigated whether longer-term cortisol exposure modified hepatic glucocorticoid
receptor (GR) status and tissue responsiveness to cortisol stimulation in rainbow trout. Fish …

Cortisol is a glucocorticoid hormone which is an endocrine signaling molecule in all
vertebrates and acts through intracellular glucocorticoid receptors (GRs). Cortisol affects …

Response to stress during the spawning period of sockeye salmon (Oncorhynchus nerka)
was investigated by measuring cortisol, selected steroids and glucose levels in the plasma …

Cortisol is an essential regulator of neuroendocrine stress responses in teleost. Cortisol
performs its effects through the modulation of glucocorticoid receptor (GR) and …

Acute temperature stress in animals results in increases in heat shock proteins (HSPs) and
stress hormones. There is evidence that stress hormones influence the magnitude of the …

Two groups of female rainbow trout displaying consistently divergent plasma cortisol
responses to a 3 h period of confinement were identified following five separate confinement …
