| O objetivo deste trabalho foi determinar o efeito da inclusão de feijão-caupi (Vigna unguiculata) na ração sobre o desempenho de juvenis de tambaqui (Colossoma macropomum). O experimento foi conduzido em delineamento inteiramente casualizado, com três repetições de 20 juvenis de tambaqui (10 g), alocados em caixas d'água de 310 L. Os peixes foram alimentados por 60 dias com rações isonitrogenadas e isoenergéticas, com seis níveis de inclusão de feijão-caupi: 0, 5, 10, 15, 20 e 25%. Foram determinadas as relações corporais e de desempenho produtivo. Não houve diferença significativa entre os tratamentos. Juvenis de tambaqui podem ser alimentados com inclusão de até 25% de feijão-caupi na ração. |

| The objective of this work was to determine the dietary lysine (DL) and dietary arginine (DA) requirements of dourado (Salminus brasiliensis), through dose-response trials using the amino acid profiles of whole carcasses as a reference. Two experiments were carried out in a completely randomized design (n=4). In the first experiment, groups of 12 feed-conditioned dourado juveniles (11.4±0.2 g) were stocked in 60 L cages placed in 300 L plastic indoor tanks in a closed circulation system. Fish were fed for 60 days on diets containing 1.0, 1.5, 2.0, 2.5, 3.0, or 3.5 % dietary lysine. In the second experiment, dourado juveniles (27.0±0.8 g) were fed for 60 days on semipurified diets containing arginine at 1.0, 1.5, 2.0, 2.5 or 3.0%, in similar conditions to... |

| The objective of this work was to evaluate corn gluten meal (CGM) as a substitute for fish meal in diets for striped catfish (Pseudoplatystoma fasciatum) juveniles. Eight isonitrogenous (46% crude protein) and isoenergetic (3,450 kcal kg-1 digestible energy) diets, with increasing levels of CGM - 0, 6, 12, 18, 24, 30, 36, and 42% -, were fed to juvenile striped catfish (113.56±5.10 g) for seven weeks. Maximum values for weight gain, specific growth rate, protein efficiency ratio and feed conversion ratio, evaluated by polynomial quadratic regression, were observed with 10.4, 11.4, 15.4 and 15% of CGM inclusion, respectively. Feed intake decreased significantly from 0.8% CGM. Mesenteric fat index and body gross energy decreased linearly with increasing... |
