Abstract
O objetivo deste trabalho foi avaliar o uso de peixes marinhos no crescimento de tilápia-do-Nilo, Oreochromis niloticus. Desenvolveu-se o experimento em delineamento inteiramente casualizado com três tratamentos (ração para peixes com 28% de PB, Pellona harroweri e Pomadasys croco), três repetições cada. Utilizaram-se 63 peixes, com peso médio inicial de 3,059±0,846 g e 44,1±4,0 mm para o tratamento com ração, 3,015±0,892 g e 44,6±4,5 mm para o tratamento com P. harroweri e 2,736±0,803 g e 43,6±4,5 mm para o tratamento com P. croco, distribuídos homogeneamente em nove tanques de alvenaria de 2 m3 cada, contendo sete peixes por tanque. Após 91 dias, os resultados indicaram que as dietas com ração resultaram em melhores ganhos em peso e crescimento específico (P < 0,05). A tilápia-do-Nilo, mesmo sendo uma espécie omnívora, aceitou bem as dietas compostas pelas espécies de peixes marinhos utilizadas neste trabalho. PALAVRAS-CHAVES: Alimentação de peixes, aqüicultura alternativa, Oreochromis niloticus. The objective of this work was to verify the use of marine fish on Nile tilapia, Oreochromis niloticus, growth performance. Sixty three Nile tilapia juveniles, with an average weight and length of 3.059±0.846 g and 44.1±4.0 mm to treatment with ration, 3.015±0.892 g and 44.6±4.5 mm to treatment with Pellona harroweri and 2.736±0.803 g and 43.6±4.5 mm to treatment with Pomadasys croco, were stocked into nine floating cages with 2 m3 (seven fish per cage), in a complete randomized design with three treatments (ration to fish with 28% PB, P. harroweri and P. croco), in three replicates each. After ninety one days, results showed that diet with ration produced a better weight gain, specific growth rate (P < 0.05). The Nile tilapia is an omnivorous species, but fed on marine fish used in this work. KEY- WORDS: Alternatives aquaculture, feeding of fish, Oreochromis niloticus.
