Maldives-focused research offers solutions to reduce ‘ghost nets’ that trap sea turtles
Action to prevent thousands of turtles being trapped by abandoned fishing nets in the Indian Ocean is needed urgently, a University of Derby study has concluded.
Researchers are recommending that manufacturers and fishing authorities improve the traceability of nets and other fishing gear to reduce turtle deaths caused by the so-called “ghost nets”, which break off or are discarded.
The study, published under the title ‘Untangling the origin of ghost gear within the Maldivian archipelago and its impact on olive ridley (Lepidochelys olivacea) populations’ in the open access journal Endangered Species Research, examined information about “ghost nets” found around the Maldives in the Indian Ocean over a period of 51 months.
The information was collated by the UK-based Olive Ridley Project charity, which was set up by University of Derby researcher Martin Stelfox in response to the large number of Olive Ridley sea turtles he found entangled in nets while on research trips to the Indian Ocean.
Over that time period, a total of 752 abandoned nets were found and 131 turtles entangled in netting. Around 97 per cent of the turtles found entangled were Olive Ridley turtles.
However, it has been estimated that this number of “ghost nets” could actually have entangled between 3,400 and 12,200 turtles in that time.
The study found that nets with a larger mesh size, nets which were blue in colour, and fragments of net which did not have floats attached to them were more likely to cause entanglement.
Martin said: “What this research gives us is an opportunity to look at the feasibility of making fishing gear, including nets, more traceable to the individuals, companies and communities using it.
“That will require better co-ordination and information-sharing between manufacturers and the authorities which regulate sea fishing around the world.”
One possible solution is to use blockchain data storage technology, which is already being trialled in the Pacific, to improve traceability and accountability in the fishing industry.
The impact of seasonality, particularly the north-east monsoons, and the migration patterns of Olive Ridley turtles to identify where they overlap with fishing activity, should also be the subject of urgent future research, the study advocates.
The report states: “Temporary closures in these overlapping areas during high turtle activity may reduce the likelihood of turtle entanglement as a result of gear loss caused by operational damage or general discard.
“Moreover, establishing free, port side or landing site recycling facilities would discourage small and large-scale fishers from dumping damaged or end of life gear at sea.”
Martin said: “While our solutions must be realistic and workable, they could, if implemented, reduce the amount of fishing equipment which is lost in the ocean and could help encourage better reporting of gear which is lost.
“That could, in turn, lead to fewer turtles dying after becoming entangled in ghost nets in the ocean.”
Every year, it is estimated that 640,000 tonnes of ghost nets are discarded at sea, which amounts to 10 per cent of the world’s total marine debris. Ghost nets are commercial fishing nets that have been lost, abandoned, or discarded at sea.
Every year, they are responsible for trapping and killing millions of marine animals including sharks, rays, bony fish, turtles, dolphins, whales, crustaceans, and birds. Ghost nets cause further damage by entangling live coral, smothering reefs and introducing parasites and invasive species into reef environments.
Between July 2013 and July 2018, there were 601 turtle entanglements recorded in discarded fishing nets in the Maldives alone.
The Maldives is home to five species of sea turtles, the most frequently spotted out of these five are the Green Sea Turtle (Chelonia mydas) and the Hawksbill Turtle (Eretmochelys imbricata). Loggerheads, Leatherbacks and Olive Ridley turtles are the rarer species. Although all species of turtles have been protected by law in the Maldives since 1995, the major threats to these animals continue to be egg and meat poaching and entanglement in marine debris.
All seven of the world’s species of sea turtles are on IUCN’s Red List with the Hawksbill turtle being listed as the most critically endangered out of the seven.
At Canareef Resort Maldives, one of the most popular experiences for guests is the dolphin tour. The abundant presence of dolphins in the surrounding waters ensures that each cruise offers a remarkable encounter with these marine creatures, creating lasting memories for visitors.
Every dolphin tour at Canareef provides an opportunity to observe pods of dolphins gliding and leaping across the waves. Guests often describe the sight of spinner dolphins darting through the clear ocean as a defining image of the Maldives’ natural marine beauty.
Morning cruises and sunset tours alike are guided by experienced staff, who share insights as dolphins appear in their natural environment. Many guests recount moments when dolphins swim alongside the boat, a spectacle that creates a unique sense of connection.
The activity is regarded as more than just an excursion; it is considered a celebration of nature and a highlight of a stay at Canareef. It allows guests to experience the Maldives in a way that underlines why dolphins are seen as ambassadors of the islands.
For travellers seeking encounters with dolphins amid turquoise waters, Canareef presents an ideal opportunity. The resort also offers seasonal promotions, including early booking discounts for the remainder of this summer, next winter, and summer 2026.
At Dusit Thani Maldives, the experience of the ocean begins directly at the doorstep. Situated within the UNESCO-protected Baa Atoll Biosphere Reserve, the resort is surrounded by one of the most vibrant house reefs in the country, offering guests the opportunity to explore a thriving underwater world just steps from their villa.
What distinguishes the resort is its 360-degree house reef. Each villa, whether set above the lagoon or along the beach, opens directly onto the water. Guests can enter the ocean within moments of leaving their deck, where coral gardens, schools of tropical fish, and turtles can often be seen. The seamless access allows families, beginners, and experienced snorkellers to engage with the reef naturally, without the need to plan or schedule an excursion.
The location within the Baa Atoll Biosphere Reserve makes every swim a part of a wider story of conservation and discovery. Recognised globally for its corals and tropical marine life, the reserve becomes a key gathering site for manta rays and whale sharks during the season. Around the reef, visitors can observe parrotfish, angelfish, eagle rays, and reef sharks, making it a living example of biodiversity and preservation.
Life at the resort is centred on this connection with the sea. Guests may begin their day with a morning swim, take part in a guided snorkelling safari with marine experts, and conclude by observing the coral gardens as they take on new colours in the evening light. The ocean becomes not simply a backdrop but an integral part of daily life.
The PADI-certified Dive and Watersports Centre further enhances this relationship with the ocean, offering night snorkels, freediving, drift dives, and marine education programmes designed for families. Guests are supported to safely explore the biodiversity of the atoll at their own level, whether through a gentle introduction or more advanced diving experiences.
Jean-Louis Ripoche, Area General Manager, Dusit Maldives, noted that snorkelling at the resort is not treated as an activity but as part of the rhythm of island life. He explained that the reef begins where the villa deck ends, allowing guests the freedom to explore the ocean at their own pace and making the location distinctive in its accessibility and natural beauty.
At Dusit Thani Maldives, the distinction between villa and ocean fades away. From sighting turtles at sunrise to drifting beside reef sharks at dusk, every moment reinforces the natural character of the Maldives and the unique setting of the resort.
Angsana Velavaru invites travelers to immerse themselves in a rhythm shaped by tides, coral gardens, and island breezes. This oceanfront retreat is located in one of the Maldives’ most vibrant marine environments. It is known as “Turtle Island” and is a 40-minute seaplane ride from Male’.
