The effect of enriched Artemia with two probiotics, Bacillus subtilis and Pediococcus pentosaseus on growth, survival and carcass composition indices in western white leg shrimp post larva

he use of probiotics in aquaculture has shown that it can make more productive in the industry. With this purpose, in this study the effect of two bacterial species Bacillus subtilis and Pediococcus pentosaseus were examined as probiotics on growth, survival and biochemical composition of the carcass of vannamei post larvae (PL). Hence, three treatments, each with three replicates were included Bacillus treatment (B), Pediococcus treatment (P) and integrated treatment of Bacillus and Pediococcus (BP) through the enrichment of Artemia consumed by larval shrimp vannamei from the Mysis III to the PL15. Unenriched Artemia with probiotics was used to feed larvae in control treatment. At the end, growth and survival indices demonstrated an increasing significantly (P <0.05) procedure in consumption of probiotics and the greatest effect was also found in integrated treatment. The effects of probiotic consumption on biochemical carcass factors were showed no significant differences between different treatments. Finally, based on obtained finding of this study, described bacteria could be effective on improving growth and production efficiency of vannamei PL , but no effect on biochemical body factors.
