DIAS, Danielle de Carla et al. Probiotic in feeding of juvenile matrinxã (Brycon amazonicus): economic viability. Acta Sci., Anim. Sci. [online]. 2012, vol.34, n.3, pp. 239-243. ISSN 1807-8672. http://dx.doi.org/10.4025/actascianimsci.v34i3.13257.
This study aimed to analyze the economic feasibility of supplement probiotics Bacillus subtilis to "matrinxã" Brycon amazonicus, raised in cages. The experiment was conducted at the Polo Regional Vale do Ribeira, in Pariquera-açu municipality, São Paulo State, Brazil, from February to July 2009. A total of 960 juvenile matrinxã were stocked in twelve 2.7 m3-net cages (1.5 x 1.5 x 1.2 m), in ponds with a total area of 600 m2 and an average depth of 1.50 m. The tests were conducted with a control treatment (T1) and two probiotic doses (T2 = 5 g and T3 = 10 g kg-1 of diet) with four replicates. Results showed that T2 produced better economic performance for matrinxã at the juvenile stage in intensive rearing system.
