Resumen

The Arapaima gigas, a native fish species in the Amazon basin, presents particular biological and zootechnical characteristics, along with substantial economic value, that make it a promising candidate for its production within intensive aquaculture systems. To date, different studies have been conducted to (a) increase the understanding of its digestive physiology in relation to feeding habits, (b) determine its nutritional requirements at different developmental stages, (c) assess the potential use of alternative ingredients in diets, and (d) elucidate its feeding behavior patterns in captivity to improve feeding strategies. However, important gaps still remain in the available information related to the above-mentioned aspects that compromise the formulation of efficient and balanced aquafeeds used in the different production phases of this species. This article provides a comprehensive review of the current state of knowledge regarding digestive physiology, nutritional requirements and feeding strategies of A. gigas with the main objective of identifying areas that require further research for application in developing suitable and sustainable feeds for the species.
