Resumo: | This study consisted of two experiments. The first objective was to demonstrate the technical feasibility of separate BFT tank technology in juvenile cultivation of Nile tilapia, for monitoring quality variables of water and productive performance. The fish were fed different combinations of artificial food (balanced diet) and natural food (bioflocs biomass). As the supply of food decreased the tanks increased the biomass supply bioflocs. Bioflocs biomass was produced in an external tank 500 L, separately from the cultivation system (separate tank BFT). You can reduce the regular feeding rates of juvenile Nile tilapia, with artificial diets, 25 %, without losses, if bioflocs to provide wet grown animals, as a food supplement, in equal proportion. The second objective was determine the effects of the provision of dried bioflocs biomass to Nile tilapia juveniles, stocked in experimental rearing tanks for 8 weeks, upon selected variables of water quality, growth performance and effluents quality. Fish was fed with different combinations of artificial diets and bioflocs biomass, in the wet form (in natura) or dried. As the supply of artificial diet was decreased, the provision of bioflocs biomass was increased in the same proportion. The bioflocs biomass was produced in two extra 500-L tanks. The growth performance of fish that were partially fed with dried bioflocs biomass has remained below what was observed in the tanks supplied with the wet bioflocs biomass. Due to the lacking of positive results, there is not any rationale to dry the bacterial bioflocs aiming at the delivery of it as a dried biomass to the cultured fish. |

No primeiro, objetivou-se demonstrar a viabilidade tÃcnica da tecnologia do tanque BFT (c/bioflocos) avulso no cultivo de juvenis de tilÃpia do Nilo, pelo monitoramento de variÃveis de qualidade de Ãgua e de desempenho produtivo. Os peixes foram alimentados com diferentes combinaÃÃes de alimento artificial (raÃÃo balanceada) e de alimento natural (biomassa de bioflocos). à medida que diminuÃa o aporte de raÃÃo aos tanques, aumentava o fornecimento de biomassa de bioflocos. A biomassa de bioflocos foi produzida em um tanque externo de 500 L, em separado do sistema de cultivo (tanque BFT avulso). Os tanques de cultivo que receberam aplicaÃÃes diÃrias de bioflocos apresentaram concentraÃÃes de nitrito na Ãgua significativamente menores do que as observadas nos tanques nos quais a Ãnica fonte de alimentaÃÃo dos peixes foi a raÃÃo comercial. Concluiu-se que à possÃvel reduzir as taxas regulares de arraÃoamento de juvenis de tilÃpia do Nilo, com raÃÃes artificiais, em 25%, sem prejuÃzo zootÃcnico, caso se forneÃa bioflocos Ãmidos aos animais cultivados, como suplemento alimentar, em igual proporÃÃo. O segundo experimento teve como objetivo determinar os efeitos do fornecimento de biomassa seca de bioflocos a juvenis de tilÃpia do Nilo, mantidos em tanques experimentais de cultivo por oito semanas, sobre variÃveis selecionadas de qualidade de Ãgua, desempenho zootÃcnico e qualidade de efluentes. Os peixes foram alimentados com diferentes combinaÃÃes de raÃÃo balanceada e biomassa de bioflocos, na forma Ãmida (in natura) ou seca. à medida o aporte de raÃÃo aos tanques foi menor, o fornecimento de biomassa de bioflocos foi proporcionalmente maior.
