The capacity of fishes to cope with environmental variation is considered to be a main
determinant of their fitness and is partly determined by their stress physiology. By 2100 …

Previous reviews of stress, and the stress hormone cortisol, in fish have focussed on
physiology, due to interest in impacts on aquaculture production. Here, we discuss cortisol in …

Plastic pollution is a growing global emergency and it could serve as a geological indicator
of the Anthropocene era. Microplastics are potentially more hazardous than macroplastics …

With the continued growth of the aquaculture industry and increasing scientific discussion
over the potential for negative events to give rise to suffering, research into the welfare of …

Reactions to stress vary between individuals, and physiological and behavioral responses
tend to be associated in distinct suites of correlated traits, often termed stress-co** styles …

The assumption that the acute response to stress is adaptive is pervasive in the literature,
but there is little direct evidence regarding potential positive fitness consequences of an …

Individual differences in physiological and behavioural responses to stressors are
increasingly recognised as adaptive variation and thus raw material for evolution and fish …

During past two decades, steroid hormones have raised significant public concerns due to
their potential adverse effects on the hormonal functions of aquatic organisms and humans …

We developed an original analytical method for monitoring five estrogens, nine androgens,
nine progestogens, six glucocorticoids, and one mineralocorticoid in one water sample …

Social interactions in small groups of juvenile rainbow trout (Oncorhynchus mykiss) lead to
the formation of dominance hierarchies. Dominant fish hold better positions in the …
