Resumo: The present work assessed the effect of the temperature on the feed ingestion (intake) by pacu (Piaractus mesopotamicus), relating the feeding behavior to the gastric transit time (GTT) and gastric evacuation time (repletion index) (GET). Ninety-six fingerlings pacus with 160 g were placed in 150-liter experimental aquaria with continuous water flow. They were fed by a commercial floating feed (28% crude protein) in two water temperatures: 23 and 27°C. GTT was significantly influenced by the water temperature, showing means values of 36h and 14h for 23 and 27°C, respectively. GET was slower in fish maintained at the lowest temperature, where they reached the lowest repletion indices (0.36) in a period of time 166.67% faster (21h)

Foram utilizados 96 juvenis de pacu com peso aproximado de 160 g, alojados em aquários de 150 litros com fluxo de água contínuo, alimentados com ração extrusada comercial, contendo 28% de proteína bruta e submetidos a duas temperaturas de cultivo: 23°C e 27°C. O delineamento experimental utilizado foi inteiramente casualizado. O tempo de trânsito gastrintestinal (TTG) foi significativamente influenciado pela temperatura, com médias de 36h e 14h para 23°C e 27°C, respectivamente. O tempo de evacuação gástrica (TEG) foi mais lento a 23°C do que a 27°C, temperatura na qual se registraram os menores índices de repleção (média de 0,36) em um tempo 166,67% mais rápido (21h)Editora da Universidade Estadual de Maringá2008-03-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/121910.4025/actascianimsci.v27i3.1219Acta Scientiarum.
