Sea cucumbers are an Indonesian fisheries export commodity. Sea cucumber populations that are endangered in nature encourage sea cucumbers to be produced through hatchery and nursery. Through nursery, it is expected that sea cucumber juvinales are stronger and can increase survive rate when stocked in growth container or restocked. This study aims to provide better sandfish nursery techniques and local area characteristics to support the hatchery activities. This study was conducted in May July 2018 at the Hatchery CV Pesona Manir Rat, Southeast Maluku Regency. Juvenile sandfish 30-36 days old, rearing in hapa measuring 100 x 100 x 70 cm with a density of 200 individuals / hapa. In one tank rearing is placed one hapa. During rearing, 100-150% of water is changed and given one liter Navicular sp. every day. Aeration was installed 4 point on each hapa and water quality measurement were conducted every day. At the end of the study, body length measurements and mortality calculations were conducted. The result is that sea cucumber juvenile which is maintained has an absolute growth ranging from 1.98 to 2.1 cm with an average absolute growth of 2.03 cm. The average mortality obtained was 53.83% with a range of 53% 55%. Based on the discussion it was concluded that this technique can be applied in sandfish nursery.
