In our study, we aimed to investigate if short-term cyclic periods without food followed by periods of food availability elicit compensatory growth in juvenile matrinxã (Brycon amazonicus), an omnivorous freshwater fish and one of the most valued species in commercial fish farming in Brazil, especially in the Amazonian region. Despite the increasing growth of aquaculture in Brazil, there is a lack of information on the general management of the farmed species, mainly concerning feeding management. Appropriate feeding protocols could help farmers to reduce costs and minimize negative effects on the environment while improving the rearing system of matrinxã and other species.
