Enriched Artemia Nauplii with Commercial Probiotic in the Larviculture of Angelfish Pterophyllum scalare Lichtenstein (1823)

This study evaluated the effect of enriched artemia nauplii with commercial probiotic for angelfish larvae determining growth perfomance,survival and modulation of the intestinal microbiota.Therefore,it experiment occurred in completely randomized design with five treatments(T1-0.0,T2-1.5,T3-3.0,T4-4.5 and T5-6.0g of commercial probiotic)and four replaces during 20 days.After larvaculture,post larvae passed by biometric procedures to determine productive performance and then microbiological analysis.Occurred reduction of total heterotrophic bacteria while increased lactic acid bacteria in the intestinal tract from the post larvae for treatments T3,T4 and T5.The commercial probiotic also increased the survival and performance as final weight,weight gain and specific growth rate.For these reasons,the use of 3g of commercial probiotic promotes greater performance and intestinal modulation for angelfish larvae.
