Yeast and lactic acid bacteria are often used as probiotics. This study aimed to determine the effect of giving yeast and LAB probiotic using fruit waste as a microbial medium on the productivity of tiger shrimp postlarvae (Panaeus monodon). As many as 120 tiger shrimp post-larvae were acclimatized for 2 days. The tiger shrimps post-larvae were divided into 4 treatments; a control group tiger shrimp post larvae without given yeast and LAB probiotic (P0); treatment 1 (P1); treatment 2 (P2) and treatment 3 (P3) in sequence shrimp post larvae given 25 ml; 50 ml; and 75 ml yeast and LAB probiotic/15 L of water. Yeast and LAB probiotic was given in shrimps post-larvae live media for 3 weeks(once per week). Data were analyzed using analysis of variance (ANOVA) following the Duncan test. The results of this study showed that yeast and LAB probiotic at a dose 25ml/15 L of water can increase the growth of tiger shrimp post-larvae, reduce the amount of Vibrio sp. and maintain the quality of tiger shrimp post larvae environment.
