In the present study, different probiotics application strategies were evaluated with the objective to show the methodology that have the ability of enhance growth parameters and water quality variables in no water exchange super intensive heterotrophic culture of Litopenaeus vannamei. The experiment was realized in laboratory during thirty days. It consisted in twelve 48-L plastic tanks stocked with 40 shrimp (2.26 ± 0.02 g initial weight) each. Tanks received flow-through water coming from one of four 500-L sources corresponding to the treatments with two commercial probiotics (Bacillus sp.) added in the water (WP), feed (FP), water and feed (WFP) and without probiotic addition (NP). Shrimp growth and water quality parameters were recorded during the culture period and bacteriological analysis of shrimp hepatopancreas performed at the end of the experiment. Overall results indicated that growth performance was negatively affected when the probiotic was added in the water, but water quality was significantly improved in all probiotic treatments. The results obtained in this study suggest that all probiotics application strategy tested have the ability to interfere in any ways on the growth parameters and the physical and chemical water quality variables in L. vannamei super intensive heterotrophic culture.
