“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 coastal marine ecosystems and local food production all around the world, especially in the Federated States of Micronesia (FSM), a North Pacific country of over 600 islands.

For the last 17 years, Martin Selch and his wife Delphia have been growing endangered species of clams on the island of Kosrae, the smallest of FSM’s four 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.

“Giant clams have become threatened all around the world,” says Martin Selch. Climate change and sediment runoff has caused many of the local giant clam species to become endangered or extinct. However, Martin and Delphia have dedicated their lives to cultivating six varieties of clams including Tridacna gigas, the world’s largest mollusk species, that previously had disappeared from Kosrae’s waters.

In this short documentary, discover the importance of giant clams, their contribution to food security and the marine environment, and meet the people dedicated to keeping them around forever.
