This research was conducted on December 1, 2018 until December 15, 2018 at the Fisheries Laboratory of the Faculty of Agriculture, Animal Husbandry, Muhammadiyah Malang. The method in this study is the experimental method. The design used in this study is a Completely Randomized Design (CRD). Treatment A is a control treatment, treatment B with a dose of papaya leaf extract 0.75 mg / l, treatment C with a dose of papaya leaf extract 1 mg / l, treatment D with a dose of papaya leaf extract 1.25 mg / l and treatment E with a dose papaya leaf extract 1.5 mg / l. The results showed that there were significantly different treatments for the addition of papaya leaf extract to the hatching rate of carp punten eggs, with treatment C (1 mg / l) being the best treatment in increasing the hatching rate of 89.5%. Furthermore, the addition of papaya leaf extract to the prevalence of saprolegnia sp fungus in punten carp eggs showed a significant difference between treatments, with treatment C (1 mg / l) being the best treatment in suppressing the prevalence of saprolegnia sp fungi with a prevalence rate of only 10.5% . Then the addition of papaya leaf extract to the goldfish survival rate showed a significant difference between treatments, with treatment C (1 mg / l) being the best treatment in increasing the value of Punten Carp survival arte with a survival rate of 94.68%. Therefore from this study it can be seen that the safe dose in the use of papaya leaf extract is to use a dose of 1 mg / l to suppress the prevalence of saprolegnia sp fungi and increase the hatching rate and increase the survival rate of the Punten carp
