Koi fish (Cyprinus rubrofuscus) is a type of fish that has high economic value and is easy to maintain. This fish has a large size and fast growth and attractive body shape and color. The purpose of this study was to determine the effect of giving probiotics on the vitality of koi fish (Cyprinus rubrofuscus) and to find out the best dose that gives effect to giving probiotics on the growth and survival of koi fish (Cyprinus rubrofuscus). This research was carried out from 20 February to 20 April 2022 which is located at the Biota and Environmental Engineering Laboratory, Faculty of Fisheries and Marine Sciences, Muslim University of Indonesia.The method used in this study was an experimental method with a completely randomized design (CRD) consisting of four treatments (A, B, C and D). Each treatment was three replication. The dose for each treatment is A (0 ml), B (5 ml), C (10 ml) and D (15 ml). Then in this study there are 3 parameters, namely weight growth, length growth and survival rate. Based on the results of the study which showed that feed enrichment with probiotics has a significant effect on the growth of weight and length but does not affect the survival rate of koi fish; treatment of 10 ml dose of probiotics gives the best growth; water quality is at optimal conditions for the growth and survival of koi fish.
