Fish are the most diversified group of vertebrates and, although progress has been made in
the past years, only relatively few fish species have been examined to date, with regards to …

The use of agrochemicals has grown in recent years following the increase in agricultural
productivity, to eliminate weeds that can compromise crop yields. The intensive use of these …

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 …

The brain, particularly the hypothalamus, integrates input from factors that stimulate
(orexigenic) and inhibit (anorexigenic) food intake. In fish, the identification of appetite …

Acoustic noise is known to have a variety of detrimental effects on many animals, including
humans, but surprisingly little is known about its impacts on foraging behaviour, despite the …

Second only to the mouse and rat, the zebrafish is the most popular animal model in
biomedical research. Rapid embryonic development and transparent organogenesis give it …

The vertebrate hypothalamus–pituitary–adrenal (HPA; or interrenal) axis plays pivotal roles
in animal development and in physiological and behavioral adaptation to environmental …

In rainbow trout the magnitude of the cortisol response to stress shows both consistency
over time and a moderate to high degree of heritability, and high responding (HR) and low …

The homeostatic regulation of food intake relies on a complex network involving peripheral
and central signals that are integrated in the hypothalamus which in turn responds with the …

The zebrafish (Danio rerio) has become a well-established experimental model in many
research fields but the loss of the primary sex-determining region during the process of …
