Indonesia recently established the world’s largest manta ray sanctuary. Nearly 6 million square kilometers of ocean surrounding the island nation will now serve as a protected area for both oceanic and reef manta rays. Recent research shows the tourism value of mantas globally is nearly $140 million per year. Mantas are currently being targeted by fisherman for their gill plates — a purported medicinal tonic in Southeast Asia.

Indonesia’s decision is a step in the right direction, says Sarah Lewis, Indonesian Manta Project leader with the Manta Trust. “Coming from one of the world’s largest manta fishing nations, this news marks a milestone for manta conservation and awareness not just nationally but on a global scale.”
