Momentum of increasing demand for tilapia seed is not quickly and precisely can be responded to by farmer’s tilapia breeder especially due to constrained management of the production process. It was identified that the perpetrators of tilapia nursery farming in Sanding Village faced a classic problem, namely the high mortality of fish seeds and the low rate of growth of tilapia seedlings during the nursery. This is shown by the fact that more time is needed for a nursery period, from 45 days to 60 days to reach an average weight of 10 gram fish seeds from an average initial weight of 3 grams. This study aims to analyze the effect of giving probiotics on the survival and growth rate of tilapia seedlings. This research is an experimental study with the innovation of probiotics in commercial feed for tilapia seedling nursery. The study was conducted in Sanding Village, Tampaksiring District, Gianyar Regency. The effect of probiotic administration on survival and growth rate of tilapia seedlings was analyzed by t-test. Competitiveness and financial efficiency are analyzed using a policy analysis matrix (PAM) approach. The results showed that probiotic administration significantly affected the survival and growth rate It is proven that technological innovation can provide a guarantee for the sustainability of tilapia nursery farming in the future. Based on these conclusions it is recommended that tilapia fish breeders use probiotics so that the mortality rate of fish seeds can be suppressed and the growth rate of fish seeds will be better.
