Resumo: Knowing the optimal feeding rate for a given species is important not only to promote higher growth and greater feeding efficiency, but also to prevent the deterioration of water quality resulting from excess food. This study aimed to evaluate the performance of the fat-snook Centropomus parallelus cultivated in net cages under the effect of different feeding rates (1, 1.5, 2 and 2.5% live biomass daily and control rate up to apparent satiation) in natural environment conditions. For 40 days, each treatment was evaluated in triplicate, in which the biological parameters (survival, specific growth rate, final average weight and length) and nutritional parameters (feed conversion ratio) were assessed. A polynomial regression analysis of specific growth rate suggests that in average temperatures of 25°C, the feeding rate which results in best growth for juvenile fat-snook is 1.7% of live biomass per day.

O presente estudo teve como objetivo avaliar o desempenho do robalo-peva, Centropomus parallelus cultivado em tanques-rede flutuantes sob o efeito de diferentes taxas alimentares (1; 1,5; 2 e 2,5% da biomassa ao dia e a taxa controle que foi até a saciedade), em condições de cultivo no ambiente natural. Durante 40 dias, cada tratamento foi avaliado em triplicatas e foram verificados os parâmetros biológicos (sobrevivência, taxa de crescimento específico, peso e comprimentos médios finais) e nutricionais (taxa de conversão alimentar aparente). A análise de regressão polinomial da taxa de crescimento específico sugere que em temperaturas médias de 25°C a taxa alimentar que resulta em melhor crescimento para juvenis de robalo-peva é de 1,7% da biomassa viva por dia.Editora da Universidade Estadual de Maringá2011-04-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersioncriação em condições naturaisapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/1141310.4025/actascianimsci.v33i4.11413Acta Scientiarum.
