The stress response in teleost fish shows many similarities to that of the terrestrial
vertebrates. These concern the principal messengers of the brain-sympathetic-chromaffin …

The fish gill is a multipurpose organ that, in addition to providing for aquatic gas exchange,
plays dominant roles in osmotic and ionic regulation, acid-base regulation, and excretion of …

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 …

In fish, the catecholamine hormones adrenaline and noradrenaline are released into the
circulation, from chromaffin cells, during numerous 'stressful'situations. The physiological …

Tryptophan is an essential amino acid with a huge functional versatility, in addition to its
participation in protein synthesis. Because of the complexity of its metabolism, and the …

Selective serotonin reuptake inhibitors (SSRIs) are among the pharmaceutical compounds
frequently detected in sewage treatment plant effluents and surface waters, albeit at very low …

That ventilation in fish is driven by O2 has long been accepted. The O2 ventilatory drive
reflects the much lower capacitance of water for O2 than for CO2, and is mediated by O2 …

The goal of this review is to discuss and clarify some of the issues currently being debated
regarding the acute humoral adrenergic stress response in fish. The afferent limb of the …

The aim of the study was to investigate the effects of sublethal concentrations (0.3, 0.6 and
1.2 mg L− 1) of the herbicide Ronstar on the hematology and some immune parameters in …

It is known that tryptophan (Trp) can attenuate the stress response in fish though its role in
chronic stress has been scarcely studied. In this work, the effects of a Trp-enriched diet on …
