Cambodian villagers caught the world’s largest stingray

  • Cambodian villagers in the Mekong have discovered the largest freshwater fish in the world, a female ray weighing 300 kg.
  • The scientists electronically tagged the fish, allowing them to monitor its behavior and movements.
  • Despite fears that overfishing, pollution and sediment depletion have impacted the diversity of the river’s fish population, this finding gives hope for the health of the Mekong.

Cambodian villagers in the Mekong caught what researchers say is the world’s largest freshwater fish ever recorded, a ray that weighed 300 kg (661 lb) and took a dozen men to haul to to the shore.

Named Boramy – meaning ‘full moon’ in the Khmer language – because of her bulbous shape, the four-metre (13ft) long female was released into the river after being electronically tagged to allow scientists to monitor her movements and his behavior.

“This is very exciting news because it was the biggest fish in the world,” said biologist Zeb Hogan, former host of National Geographic’s “Monster Fish” show and now part of a conservation project on the river.

“It’s also great news because it means this part of the Mekong is still healthy… It’s a hopeful sign that these huge fish are still living (here).”

Boramy, caught in mid-June off Koh Preah, an island in northern Cambodia, broke the record for a 293kg giant catfish caught upstream in northern Thailand in 2005.

The Mekong has the third most diverse fish population in the world, according to its River Commission, although overfishing, pollution, saltwater intrusion and sediment depletion have caused stocks to plummet.

Biodiversity loss and climate change are occurring at an unprecedented rate, threatening the very survival of humanity. Nature is in crisis, but there is hope. Investing in nature can not only increase our resilience to socioeconomic and environmental shocks, but also help societies thrive.

There is a strong recognition within the Forum that the future must be net zero and positive for nature. The Nature Action Agenda initiative, within the Platform to Accelerate Nature-Based Solutions, is an inclusive, multi-stakeholder movement that catalyzes economic action to halt biodiversity loss by 2030.

Vibrant and thriving natural ecosystems are the foundation for human well-being and prosperity. The future of nature and business report found that nature-positive transitions in key sectors are good for the economy and could generate up to $10.1 trillion in annual business value and create 395 million jobs by 2030.

To support these transitions, the Nature-Based Solutions Acceleration Platform has brought together a community of Nature Champions promoting the sustainable management of the planet for the good of the economy and society. The Nature Action Agenda also recently launched the 100 million farmers initiative, which will drive the transition of the food and agricultural system to a regenerative model, as well as the BiodiverCities initiative by 2030 to create a model of urban development in harmony with nature.
