The aim of this study was to evaluate the requirement of crude protein (CP) and digestible energy (DE) in piavuçu fingerlings (Leporinus macrocephalus), for a period of 45 days. It was used 150 fingerlings with average weight of 0.40 ± 0.08g, distributed in 30 aquariums (30L) in a completely randomized design in a 3x 2 two-factorial scheme composed of three levels of crude protein (25, 30 and 35% of crude protein) and two levels of digestible energy (3,250 and 3,500 […]
