Luz, Melatonina e Estresse Oxidativo na Piscicultura

In fish, as in mammals, parts of the nervous system are involved in mechanisms for regulating body systems in tune with the environment. The photoperiod is translated into physiological information from the secretion of melatonin. There seems to be no morphophysiological barriers for this indolamine, that is, melatonin rapidly perfuses into each cell of the organism and in some cases interacts with receptors and membrane located on the cell surface. , and appears to be linked to food intake, growth, and locomotor activity in fish. They are important molecules metabolizing reactive oxygen species to inactive products and, therefore, reducing oxidative damage. This work aims to briefly survey recent articles on luminosity, melatonin and oxidative stress in fish, and correlate them with fish farming. We conclude that luminosity seems to be linked to the production of melatonin, and this antioxidant molecule, which favors the reduction of oxidative stress, seems to improve performance in the production of fish in farms. Keywords: Melatonin, oxidative stress, fish farming. DOI: http://dx.doi.org/10.18561/2179-5746/biotaamazonia.v3n3p169-176
