Sea cucumber are one of the Echinodermata type that have nutritional value in high protein content and as the sea of commodities with high economical value. The attempts to Obtain sea cucumber are Increasingly declining. Based on the review above, it is noticed that the cultivation of sea cucumber are needed to fulfill the needs of the market and restore the wild population. Sand sea cucumber breeding begins with the preparation of the broodstock rearing media, the availability preparation of the broodstock, water quality management, the broodstock feeding, the broodstock selection for high quality broodstock, conducting the artificial spawning using the method of temperature shock, egg incubation, hatching egg, and the larval rearing. The larvae were fed using the phytoplankton Chaetoceros sp. with a feeding frequency of once per day. The water quality parameters measured include temperature, DO, pH and salinity. The obstacles that were found on the sand sea cucumber breeding is the difficulty of getting the high quality of the broodstock, so the egg produced from spawning process are limited.
