Tourism threatens to overwhelm mantas and whale sharks of Hanifaru Bay

In most places a 260 percent increase in tourist arrivals would be a cause for celebration. Not so for Hanifaru Bay.

Located off the uninhabited island of Hanifaru in Baa Atoll, the bay is a small enclosed reef the size of a football field. But what makes Hanifaru Bay unique and attracts tourists is the phenomena that occurs during the south west monsoon from May to November.

Interplay between the lunar tide and the south west monsoon enables build up of a massive concentration of plankton, which in turn attracts hundreds of huge manta rays and gigantic whale sharks. It’s usual to see up to 200 manta rays in a feeding frenzy, accompanied by whale sharks. The bay is one of the two sites in Maldives which acts as a cleaning station as well as feeding site for whale sharks.

Hanifaru Bay was declared a Marine Protected site last year by the government, in recognition of its importance in the ecosystem. When the bay was featured in National Geographic magazine last year, and a BBC Natural World documentary this year, the site’s fame spread all over the world.
