There was more juveniles produced from treatment A (79%) compared to treatment B (21%). Based on this study, feeding artificial feed started from 8 days old take effect to greater growth and survival rate of coral trout larvae. Therefore, the initial time of feeding artificial feed for coral trout larvae should be done started at 8 days old. Larva ikan kerapu sunu dalam pembenihan di panti benih, diberi pakan buatan, disamping pakan alami sebagai pakan awalnya.

Perlakuan yang diujikan adalah perbedaan waktu awal pemberian pakan buatan, yaitu mulai larva umur 8 hari (A) dan mulai larva umur 15 hari (B). Penelitian dilakukan sebanyak tiga kali ulangan waktu.
