Cantang grouper (Epinephelus fuscoguttatus × lanceolatus) is an Indonesian fisheries commodity that seeded and has high economic value. Cantang grouper is also had excellence because it has fast growth and tolerance to disease, so these fish are widely cultured. The purpose of this study was to analyze the hatching rate, growth monitoring, and survival rate of cantang grouper. This research was conducted at UPT PBL Situbondo, East Java Province on December 2018 until January 2019. Spawning of the cantang grouper was done artificially. The hatching rate of cantang grouper eggs was 53.3 %, growth rate ranging from 0.0009-0.7900 gr/day and specific growth rate ranging from 10.34-29.84 %. Larvae maintenance includes feeding, measurement of water quality, and change of water. Feeding is in the form of Chlorella sp., Rotifer, Artemia sp., Acetes sp., and artificial feed. The survival rate of cantang grouper was 26.9%. The measured water quality was a temperature ranging from 29-30 °C, pH with a range of 7.9-8, and dissolved oxygen (DO) was 7 mg/L.
