Nauplii copepod is one of the zooplankton that are rarely used as a natural food in the process of fish larvae in hatchery production of marine fisheries. Copepod culture in Indonesia is still done with a static system with low productivity and difficult to predict.

This activity aims to determine the effect on the survival rate of nauplii copepod larvae of coral trout grouper. Copepods fed as naturally after administration rotifer.Metode pengamtan used is to keep records of all data obtained from these activities in the form of SR, growth and water quality From the results of these activities obtained survival rate (SR) on average at D20 for treatment A ie feeding with nauplii of copepods was 2.7% and treatment B copepod nauplii feeding without SR of 2.3%. The growth rate was higher in the treatment length A of 7.2 mm on D20 compared to the treatment without copepod nauplii (treatment B) by 6 mm on the D20. The water quality in the larval rearing tubs are still within the normal range.
