The Ecosystems Research and Development Bureau (ERDB) is asking local government units (LGUs) to demarcate “no fishing” zones in “coral bleached” Snake Island, Palawan, to help replenish depleting fish inventory in what is also a tourist haven.

The government in 2012 closed to the public Snake Island, which is found in a cluster of islands around top tourist destination El Nido, Puerto Princesa, Palawan.
