Zusammenfassung: | This study aimed to analyze the economic feasibility of supplement probiotics Bacillus subtilis to "matrinxa" Brycon amazonicus, raised in cages. The experiment was conducted at the Polo Regional Vale do Ribeira, in Pariquera-acu municipality, Sao Paulo State, Brazil, from February to July 2009. A total of 960 juvenile matrinxa were stocked in twelve 2.7 [m.sup.3]-net cages (1.5 x 1.5 x 1.2 m), in ponds with a total area of 600 [m.sup.2] and an average depth of 1.50 m. The tests were conducted with a control treatment ([T.sub.1]) and two probiotic doses ([T.sub.2] = 5 g and [T.sub.3] = 10 g [kg.sup.-1] of diet) with four replicates. Results showed that [T.sub.2] produced better economic performance for matrinxa at the juvenile stage in intensive rearing system. Keywords: fish farming, growth promoter, production cost, economic indicator. Objetivou-se analisar a viabilidade economica do uso do probiotico Bacillus subtilis na alimentacao de matrinxa Brycon amazonicus, em tanques-rede. O experimento foi conduzido no Polo Regional do Vale do Ribeira, no municipio de Pariquera-Acu, Sao Paulo, Brasil, entre fevereiro e julho de 2009. Foram avaliados 960 peixes juvenis, divididos em 12 tanques-rede de 2,7 [m.sup.3] (1,5 x 1,5 x 1,2 m) em uma area total de 600 [m.sup.2], com profundidade media de 1,50 m. Os testes foram conduzidos com um tratamento testemunha ([T.sub.1]), duas doses de probiotico ([T.sub.2] = 5 g e [T.sub.3] = 10 g [kg.sup.-1] de racao) e quatro repeticoes. Os resultados mostraram que o [T.sub.2] proporcionou melhor desempenho zootecnico e economico da matrinxa na fase de engorda no sistema intensivo de criacao. Palavras-chave: piscicultura, promotor de crescimento, custo de producao, indicador economico. |
