- Abstract
The demand of the global population for aquatic products is increasing while the production of extractive fisheries is reducing, and, in many cases, even reaching its maximum productive potential. As a consequence, it will not be possible in the short term to sustain the supply of aquatic products aimed at a population in constant growth and in demand for fish. The productive sector follows the current trend of other animal production systems, which have been seeking to sustainably increase productivity from an economic and environmental point of view, mainly requiring the contribution of nutrition to this trend. Studies with additives to the diet of captive animals is a strategy that has shown high potential for inclusion in aquaculture, with the possibility of an increase in production rates and/or improvement in the quality of the product for the consumer. Ractopamine is an additive classified as a beta-adrenergic agonist and its mechanism of action is associated with effects on fish metabolism that reduce the accumulation of fats through the inhibition of lipogenesis and stimulation of lipolysis, and by mechanisms that favor the synthesis of muscle protein. The studies carried out so far prove that there are metabolic changes in fish, although no significant differences have been found in zootechnical indexes in order to establish its use in the industry. Further research is required for a better understanding of ractopamine in fish nutrition, especially in understanding the receptors and mechanisms of action in fish.
