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 …

Basal levels of plasma cortisol in unstressed salmonid fish are normally in the range 0–5 ng
ml− 1. An acute stress such as handling or 1 h confinement caused a temporary elevation of …

Stress in teleosts is an increasingly studied topic because of its interaction with growth,
reproduction, immune system and ultimately fitness of the animal. Whether it is for evaluating …

Physical, chemical and perceived stressors can all evoke non-specific responses in fish,
which are considered adaptive to enable the fish to cope with the disturbance and maintain …

Juvenile rainbow trout Salmo gairdnen were either fed cortisol or subjected to an acute
stress daily for 10 wk to determine the long-term effects of these factors on growth …

Cortisol is the principal corticosteriod in teleost fishes and its plasma concentrations rise
dramatically during stress. The relationship between this cortisol increase and its metabolic …

Stress in fish caused by physical disturbances encountered in aquaculture, such as
handling and transport, evokes a variety of responses that may be adaptive or maladaptive …

Interspecific differences in the stress response of fish may be due, in part, to differences in
the sensitivity of target tissues to cortisol. The relative response of brown and rainbow trout …

The ultrastructure of the skin of rainbow trout, Oncorhynchus mykiss, was studied over a 7-
day period after a single meal containing cortisol. The fish experienced increased plasma …
