Egg and larval development of induced spawned Sandfish (Holothuria scabra) in hatchery
Holothuria scabra, commonly known as sandfish has a high market demand, especially in South East Asian countries such as Malaysia, Philippines and Vietnam. This species that is very popular among the Chinese is served as luxorius delicacy because it has high protein and medicinal properties. The i...

description |
Holothuria scabra, commonly known as sandfish has a high market demand, especially in South East Asian countries such as
Malaysia, Philippines and Vietnam. This species that is very popular among the Chinese is served as luxorius delicacy because it has high
protein and medicinal properties. The increasing demand for sandfish has led to the over-exploitation worldwide. Hatchery production
enables continuous seed production of H. scabra throughout the year by artificial spawning. Fifty healthy broodstocks collected from
Kampung Baru-Baru, Tuaran Sabah (6° 18’ 18.1656” N, 116° 17’43.1052” E) were acclimatized in Universiti Malaysia Sabah (UMS)
hatchery for 2 weeks prior to spawning induction. The broodstocks were fed twice a day with ground Sargassum sp. and Enhalus sp. The
combination of 3 spawning induction methods: thermal shock, desiccation and algal bath were applied. Total fertilized eggs obtained were
approximately 700,000, with a 9 % hatching rate. The larval rearing was carried out in high density polyethylene (HDPE) tank filled with
filtered and UV treated seawater (29-30°C). The larvae were fed twice daily with Nannochloropsis sp. at a specific feeding rate. The egg and
larval development were recorded daily. The duration for each stages of larval development was as followed: Gastrula (24 hours after
fertilization), Early auricularia (Day 2), Mid auricularia (Day 4), Late auricularia (Day 6), Early doliolaria (Day 21), Late doliolaria (Day 24),
Pentactula (Day 26). |
