Previous studies have demonstrated that fish inhabiting polluted waterways often have an
impaired stress response at the organismal level. Given the possible link between the …

Postemergent salmonid fry experience a" critical period" in their development, during which
there may be a high mortality rate, so determining the long-term success of the year class …

Total cortisol, free cortisol and percent free cortisol were all significantly higher in
semelparous male chinook salmon Oncorhynchus tshawytscha than in iteroparous and …

In teleost fishes, cortisol is the major stress hormone and its level in tissues or ambient water
is considered a reliable indicator of a state of stress. Thus, measurement of cortisol can be …

Cortisol, the end product of the hypothalamus-pituitary-interrenal (HPI) axis, has been
traditionally measured in blood as indicator of stress in fish, however, the degree of …

Different life history stages of juvenile Atlantic salmon around the period of smoltification
were subjected to short term stress (confinement) over two sampling years using separate …

Two lines of rainbow trout selected for high (HR) and low (LR) responsiveness to a
standardised confinement stressor displayed a sustained divergence in plasma cortisol …

Over-winter mortality is an important selective force for warm-water fish (eg, centrarchids)
that live in temperate habitats. Inherent challenges faced by fish during winter may be …

The sustainability of commercial aquaculture production depends critically on prioritizing fish
welfare management. Besides monitoring welfare parameters such as fish behaviour and …

A microtitre plate indirect enzyme‐linked immunoassay (ELISA) was developed for
