MANTILLA C.H, Lara; VELLOJIN FURNIELES, J; GARCIA PEREZ, D  and  PERTUZ BUELVAS, V. Growth performance and survival of Oreochromis ssp. larvae using a probiotic in the feed. Rev. colomb. biotecnol [online]. 2016, vol.18, n.1, pp.90-94. ISSN 0123-3475.

The efficiency of a bio-prepared with probiotic characteristics was evaluated for promoting growth and survival of red tilapia Oreochromis ssp during sexual inversion. Through four treatments, under a completely randomized design were seeded four larvae L-1 in aquariums of 20 L, to which they were delivered, for 45 days, with Hormone commercial food of 45% CP, plus the addition of bio -prepared composed for malt extract broth and a yeast of the genus Saccharomyces in concentrations: 104 (T1), 106 (T2), 108 CFU ml-1 (T3) and (T4) control without the addition of bio-prepared. At the beginning and end of the experiment the larvae were weighed (mg), measured (cm) and counted. The physical and chemical parameters monitored water remained within ranges considered normal for fish species. The highest values for the variables of larval growth were recorded in the T2 and T3; Final weight (Pf) (305.9 ± 113.2 and 326.1 ± 79.5mg), weight gain (Gp) (299.2 ± 113.2 and 319.4 ± 79.5mg) Final Length (Lf) (2.5 ± 0.3 and 2.5 ± 0.2cm), Gain length (Gl) (1.7 ± 0.3 and 1.7 ± 0.2cm) and specific growth rate (G) (12.5 ± 0.7 and 12.7 ± 0.5% / day), likewise, the highest values of survival (S) of the larvae were recorded in T3 (68.1 ± 6.8%) and T2 (59.4 ± 20.2%). Therefore the best results were presented in larvae of T2 and T3, to which were given the bio-prepared, showing that the larvae of red tilapia have better growth and survival with the implementation of a bio-prepared probiotic.
