The channel catfish Ictalurus punctatus is an important aquaculture species in the United
States and has received considerable research attention in efforts to improve production …

Life-history theory predicts that stress responses should be muted to maximize reproductive
fitness. Yet, the relationship between stress and reproduction for semelparous salmon is …

Cortisol, the primary circulating corticosteroid in teleosts, is elevated during stress following
activation of the hypothalamus–pituitary–interrenal (HPI) axis. Cortisol exerts genomic …

Fish faced with stressful stimuli launch an endocrine stress response through activation of
the hypothalamic-pituitary-interrenal (HPI-) axis to release cortisol into the blood …

Growth rates of rainbow trout (Oncorhynchus mykiss) were assessed with respect to serum
concentrations of cortisol, glucose, and chloride following exposure to a standardized …

In the sockeye salmon (Onchorynchus nerka), as well as a number of migratory salmonid
species, the plasma level of cortisol, the main stress hormone in fish, increases during the …

Cortisol is the final product of the hypothalamic-pituitary-interrenal (HPI) axis and acts as a
gluco-and mineralo-corticoid in fish. Long-term elevations of cortisol have been linked to …

When Atlantic salmon parr migrate from fresh water towards the sea, they undergo extensive
morphological, neural, physiological and behavioural changes. Such changes have the …

Wild fish are frequently exposed to multiple stressors, but the influence of previous or
ongoing stress on an animal's subsequent response is poorly understood. Using wild …

Cortisol is a key hormone in the fish stress response with a well known ability to regulate
several physiological functions, including carbohydrate metabolism and the immune system …
