Restocking activities were done in collaboration with local groups by providing training in the culture and ocean-rearing of giant clams. Community involvement is critical to overcome multiple sources of mortality for giant clams, including poaching, predation, fouling of cages, typhoons and water temperature anomalies. Particular care needs to be given to selection of release sites, adequate transfer of technology to collaborators, and transport of large clams from nursery areas to release sites. 46 cohorts of giant clams have been cultured by Marine Science Institute (MSI) of the University of the Philippines-Diliman
