Amidst Clam Poaching, Marine Science Institute Grows Four Species of Clams

The University of the Philippines Marine Science Institute grows four species of clams. According to the institute, “Four species of giant clams are bred here and raised in an ocean nursery by my colleagues at the University of the Philippines in an effort to restock the bivalves, whose wild populations are perilously low.”

In the 70s, the giant clams were close to becoming extinct, but there were efforts after that to reproduce the close-to-extinct species.
