Abstract
The sea cucumber, Holothuria scabra, commonly known as sandfish, is one of the most expensive and thus, heavily exploited species of tropical sea cucumber. Increase in demand and high market value have driven the exploitation of this species resulting in severe depletion of wild populations. Development of culture technology for H. scabra, to augment fishery production and rebuild natural stocks through the release of hatchery-produced juveniles, has been achieved in several countries with varying levels of success. Mass production of sea cucumber (sandfish; Holothuria scabra) juveniles is carried out in periphyton-based ocean nursery systems in the Philippines. However, detailed studies on the importance of periphyton as a food source for post-settled juveniles, and on factors influencing periphyton development and composition are scarce. Such information is critical in the optimization of both culture systems and husbandry procedures, and to improve production of sea cucumber juveniles.
