Temperature is a key factor for achieving optimum fish growth and keep the welfare of the culture. Indeed, an incorrect temperature can affect ingestion, transit, digestion, assimilation and metabolism. Furthermore, this is magnified in a fastgrowing fish such as the greater amberjack (Seriola dumerili). The culture of this species is becoming more and more important in the Mediterranean coasts mainly because of its fast development, its meat quality and its good acceptance in the market. For all these reasons, it is of utmost importance to establish a proper temperature, especially in RAS systems where this parameter can be modified quite easily, although its monitoring is especially important to avoid secondary artifacts that could compromise the metabolic and intestinal well-being of cultured fish. Taking all this into account, the aim of this study was to establish the consequences of water temperature on welfare, metabolic orchestration and intestinal integrity of greater amberjack juveniles accompanying the observed differences in growth performance (Yúfera et al., this conference).
