This study was aimed to determine the effect of various types of probiotics in the culture water to the growth and mortality of Vaname shrimp. This study consist of treatment control and treatment of various dose of probiotics. This probiotic consist of Lactobacillus plantarum, Lactobacillus fermentum, Bacillus subtilis, Bacillus licheniformis, Bacillus megaterium, Nitrobacter sp., and Nitrosomonas sp. Dependent variables in this study are weight of shrimp, length of shrimp, mortality and feed conversion ratio. The results had different of various dose probiotics application in the water showed significance for each treatment on growth and mortality of Vanname shrimp. The best results were shown in treatment P2 (2 mL/10 water) with mean value of Vaname shrimp weight is 7.447 ± 1.193 g/shrimp, the length is 10,390 ± 0,469 cm/shrimp, mortality is 41%, and the value of FCR is 0.91.
