Hanifaru Bay in the Maldives is renowned as one of the world’s premier sites for observing large aggregations of reef manta rays. This protected marine area regularly attracts up to 250 manta rays that gather to feed on plankton-rich waters, often forming feeding chains that offer a rare spectacle for divers and snorkelers. The bay’s unique currents funnel nutrient-rich plankton into the enclosed waters, creating an ideal environment for these broad-bodied rays, which are notable for their distinctive cephalic fins used to direct food into their wide mouths.

Visitors to Hanifaru Bay must adhere to strict regulations aimed at protecting the marine life. Diving is prohibited, only five boats are allowed in the bay at any time, and they must maintain low speeds and remain anchored outside a designated boundary to minimize disturbances to the rays and occasional whale sharks. Ranger boats monitor these rules to ensure compliance.

The bay’s conservation status owes much to efforts that began in 2007 when it faced the threat of commercial development. Advocacy, supported by international media attention, prompted the Maldivian government to declare Hanifaru Bay a marine protected area in 2009. In 2011, Baa Atoll, which includes Hanifaru Bay and 75 islands, was added to UNESCO’s World Network of Biosphere Reserves, a designation that aims to balance environmental protection with sustainable tourism and fishing.

There are currently about 4,000 manta rays in the Maldives, the world’s largest known national population. Each manta is identifiable by unique markings on its underside, used by researchers to monitor individual animals. Efforts to preserve these populations are supported by organizations such as the Manta Trust, a British charity dedicated to manta and devil ray research and conservation. The trust has been active in the Maldives for two decades, partnering with resorts like Four Seasons Landaa Giraavaru to fund research and educate visitors.

Manta ray tourism is a significant economic contributor, accounting for an estimated US$227.3 million in revenue in 2021—approximately 2.6% of the Maldives’ GDP. This economic value helps justify conservation efforts, as these animals are protected from fishing and trade within Maldivian waters, allowing their populations a better chance to thrive than in other regions where they face threats from overfishing and gill plate harvesting.

Despite regulations, compliance among tourists and operators varies. A 2019 study found only 44% of human-manta interactions fully followed guidelines designed to minimize disturbances, such as maintaining a minimum distance of 3 meters and avoiding behaviors that disrupt feeding or socializing. Improper interactions can reduce manta nourishment and interfere with critical behaviors like cleaning and mating.

The relationship between tourism and marine conservation in the Maldives is complex. Resort and infrastructure development have led to habitat changes that threaten coral reefs, vital ecosystems supporting diverse marine life. At the same time, some operators engage in controversial practices such as baiting sharks or rays to guarantee sightings, raising concerns about altering natural behaviors.

Local conservation initiatives focus heavily on education, aiming to foster appreciation and stewardship among Maldivians—particularly youth and women, who have traditionally had limited access to ocean activities for cultural reasons. Programs like the Maldives Manta Conservation Programme’s Moodhu Madharusa provide marine education and hands-on experiences, helping build a foundation for environmentally conscious future generations.

Marine science education is gaining ground, with new academic programs at the Maldives National University and expanded recognition of conservation as a viable career path. Entrepreneurs like Zoona Naseem, a former dive industry professional and MMCP board director, exemplify this shift by promoting local involvement in marine conservation and sustainable tourism.

Looking ahead, conservationists and educators hope to see stronger local leadership in protecting the Maldives’ unique marine environment. By connecting conservation to economic opportunity and cultural engagement, they aim to ensure that future generations continue to benefit from—and contribute to—the country’s rich ocean heritage.
