Utilização de resí­­duos de frutas em dietas para piava

Abstract

A piava (Leporinus obtusidens) é um peixe nativo das regiões sudeste e sul do Brasil, de hábito alimentar oní­­voro e com grande potencial para a piscicultura nacional. Neste estudo foi avaliado o crescimento, atividade de enzimas digestivas e composição corporal de piavas alimentadas com dietas contendo resí­­duos de frutas: uva, laranja, goiaba e figo. Foram utilizados 180 peixes (peso médio inicial = 9,53 ± 1,82 g), alimentados durante 45 dias duas vezes ao dia (5% PV). Não houve diferença no crescimento dos peixes em relação aos resí­­duos de frutas avaliados. A atividade da lipase foi significativamente maior (p = 0,0001) nos peixes alimentados com as dietas contendo resí­­duo de uva em 5,52%, 24,41% e 47,25% em relação aos alimentados com resí­­duos de figo, goiaba e laranja, respectivamente. A atividade de tripsina foi 28,88% significativamente menor (p = 0,02) nos peixes alimentados com a dieta contendo resí­­duo de laranja em relação aos alimentados com resí­­duo de uva. A quimotripsina e glicose plasmática não diferiram nos peixes alimentados com os resí­­duos nos diferentes tratamentos. Não foram observadas diferenças na gordura e na proteí­­na bruta corporal dos peixes. Os resí­­duos de frutas avaliados podem ser ingredientes alternativos em potencial em dietas para juvenis de piava.
