The essential amino acid L-tryptophan (Trp) is the precursor of the monoaminergic
neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). Numerous studies have shown that …

In the last years, studies on stress attenuation in fish have progressively grown. This is
mainly due to the interest of institutions, producers, aquarists and consumers in improving …
