This is the story of clam farming in Nam Dinh province, Vietnam. Farming clams starts out at the hatchery where clam larvae are set on fine screens in down-wellers. The young seed is later raised in up-wells, containers which allow algae rich water to be pushed up through to the juvenile clams, thereby allowing them to feed continuously and grow rapidly. Once the clam seed grows to a sufficient size, it is then put into mesh bottomed trays which are taken out to nursery rafts in the bay. Once the clams grow to a fingernail size they’re shipped to the growing areas. Here they’re planted by sprinkling them over net panels on an incoming tide so that the baby clams then work their way through the mesh of the net into the sand where they’re then protected from predators such as crabs and ducks as they grow.
