“Giant clams give the reef life,” says Delphia Selch, “but today we hardly can see them on our reef.” Giant clams play a critical role in marine ecosystems and food production all around the world, especially in the Federated States of Micronesia (FSM), a North Pacific country of over 600 islands. For 17 years, Martin Selch and his wife Delphia have been growing endangered species of giant clams on the island of Kosrae, the smallest of FSM's states with a population of under 7,000. These clams not only contribute to repopulating the reefs, but also provide sustainable and local food security. Climate change and sediment runoff has caused many local giant clam species to become endangered or extinct. However, Martin and Delphia have dedicated their lives to cultivating six varieties of giant clams including Tridacna gigas, the world's largest mollusk species, that previously had disappeared from Kosrae's waters.
