Resumo
This study aimed to analyze of using a probiotic (Bacillus subtilis) in the diet of breeding matrinxa (Brycon amazonicus) taking into account the number of oocytes, fertilization rate, hatching and final biomass. The experiment was carried out from March to November 2008. Fifty animals with mean weight 2.35 +/- 0.31 kg and mean length 53.00 +/- 1.96 cm. Two treatments were used T(1) = control group and T(2) = 10 g probiotic kg(-1) food. The induced breeding was carried out with crude extract of carp pituitary. The result showed that the number of oocytes released, fertilization rate and hatching rates were 5%, 34% and 36% higher than control group. The final total biomass of the control group was 3.6% higher compared to animals treated with probiotic. Concluded that is viable to include Bacillus subtilis in diet of matrinxa for optimizing reproductive indicators.
