Cambodian catches world’s largest recorded freshwater fish

  • Researchers say it’s the fourth giant stingray reported in the same area in the past two months, all of them females

BANGKOK: The world’s largest recorded freshwater fish, a giant stingray, has been caught in the Mekong River in Cambodia, according to scientists from the Southeast Asian nation and the United States.
The stingray, captured on June 13, measured almost 4 meters (13 feet) from snout to tail and weighed slightly under 300 kilograms (660 pounds), according to a statement Monday by Wonders of the Mekong, a joint Cambodian-US research project.
The previous record for a freshwater fish was a 293-kilogram (646-pound) Mekong giant catfish, discovered in Thailand in 2005, the group said.
The stingray was snagged by a local fisherman south of Stung Treng in northeastern Cambodia. The fisherman alerted a nearby team of scientists from the Wonders of the Mekong project, which has publicized its conservation work in communities along the river.

The scientists arrived within hours of getting a post-midnight call with the news, and were amazed at what they saw.
“Yeah, when you see a fish this size, especially in freshwater, it is hard to comprehend, so I think all of our team was stunned,” Wonders of the Mekong leader Zeb Hogan said in an online interview from the University of Nevada in Reno. The university is partnering with the Cambodian Fisheries Administration and USAID, the US government’s international development agency.
Freshwater fish are defined as those that spend their entire lives in freshwater, as opposed to giant marine species such as bluefin tuna and marlin, or fish that migrate between fresh and saltwater like the huge beluga sturgeon.
The stingray’s catch was not just about setting a new record, he said.
“The fact that the fish can still get this big is a hopeful sign for the Mekong River, ” Hogan said, noting that the waterway faces many environmental challenges.
The Mekong River runs through China, Myanmar, Laos, Thailand, Cambodia and Vietnam. It is home to several species of giant freshwater fish but environmental pressures are rising. In particular, scientists fear a major program of dam building in recent years may be seriously disrupting spawning grounds.
“Big fish globally are endangered. They’re high-value species. They take a long time to mature. So if they’re fished before they mature, they don’t have a chance to reproduce,” Hogan said. “A lot of these big fish are migratory, so they need large areas to survive. They’re impacted by things like habitat fragmentation from dams, obviously impacted by overfishing. So about 70 percent of giant freshwater fish globally are threatened with extinction, and all of the Mekong species.”
The team that rushed to the site inserted a tagging device near the tail of the mighty fish before releasing it. The device will send tracking information for the next year, providing unprecedented data on giant stingray behavior in Cambodia.
“The giant stingray is a very poorly understood fish. Its name, even its scientific name, has changed several times in the last 20 years,” Hogan said. “It’s found throughout Southeast Asia, but we have almost no information about it. We don’t know about its life history. We don’t know about its ecology, about its migration patters.”
Researchers say it’s the fourth giant stingray reported in the same area in the past two months, all of them females. They think this may be a spawning hotspot for the species.
Local residents nicknamed the stingray “Boramy,” or “full moon,” because of its round shape and because the moon was on the horizon when it was freed on June 14. In addition to the honor of having caught the record-breaker, the lucky fisherman was compensated at market rate, meaning he received a payment of around $600.


Filipinos master disaster readiness, one roll of the dice at a time

Filipinos master disaster readiness, one roll of the dice at a time

  • In a library in the Philippines, a dice rattles on the surface of a board before coming to a stop, putting one of its players straight into the path of a powerful typhoon

MANILA: In a library in the Philippines, a dice rattles on the surface of a board before coming to a stop, putting one of its players straight into the path of a powerful typhoon.
The teenagers huddled around the table leap into action, shouting instructions and acting out the correct strategies for just one of the potential catastrophes laid out in the board game called Master of Disaster.
With fewer than half of Filipinos estimated to have undertaken disaster drills or to own a first-aid kit, the game aims to boost lagging preparedness in a country ranked the most disaster-prone on earth for four years running.
“(It) features disasters we’ve been experiencing in real life for the past few months and years,” 17-year-old Ansherina Agasen told AFP, noting that flooding routinely upends life in her hometown of Valenzuela, north of Manila.
Sitting in the arc of intense seismic activity called the “Pacific Ring of Fire,” the Philippines endures daily earthquakes and is hit by an average of 20 typhoons each year.
In November, back-to-back typhoons drove flooding that killed nearly 300 people in the archipelago nation, while a 6.9-magnitude quake in late September toppled buildings and killed 79 people around the city of Cebu.
“We realized that a lot of loss of lives and destruction of property could have been avoided if people knew about basic concepts related to disaster preparedness,” Francis Macatulad, one of the game’s developers, told AFP of its inception.
The Asia Society for Social Improvement and Sustainable Transformation (ASSIST), where Macatulad heads business development, first dreamt up the game in 2013, after Super Typhoon Haiyan ravaged the central Philippines and left thousands dead.
Launched six years later, Master of Disaster has been updated this year to address more events exacerbated by human-driven climate change, such as landslides, drought and heatwaves.
More than 10,000 editions of the game, aimed at players as young as nine years old, have been distributed across the archipelago nation.
“The youth are very essential in creating this disaster resiliency mindset,” Macatulad said.
‘Keeps on getting worse’ 
While the Philippines has introduced disaster readiness training into its K-12 curriculum, Master of Disaster is providing a jolt of innovation, Bianca Canlas of the Department of Science and Technology (DOST) told AFP.
“It’s important that it’s tactile, something that can be touched and can be seen by the eyes of the youth so they can have engagement with each other,” she said of the game.
Players roll a dice to move their pawns across the board, with each landing spot corresponding to cards containing questions or instructions to act out disaster-specific responses.
When a player is unable to fulfil a task, another can “save” them and receive a “hero token” — tallied at the end to determine a winner.
At least 27,500 deaths and economic losses of $35 billion have been attributed to extreme weather events in the past two decades, according to the 2026 Climate Risk Index.
“It just keeps on getting worse,” Canlas said, noting the lives lost in recent months.
The government is now determining if it will throw its weight behind the distribution of the game, with the sessions in Valenzuela City serving as a pilot to assess whether players find it engaging and informative.
While conceding the evidence was so far anecdotal, ASSIST’s Macatulad said he believed the game was bringing a “significant” improvement in its players’ disaster preparedness knowledge.
“Disaster is not picky. It affects from north to south. So we would like to expand this further,” Macatulad said, adding that poor communities “most vulnerable to the effects of climate change” were the priority.
“Disasters can happen to anyone,” Agasen, the teen, told AFP as the game broke up.
“As a young person, I can share the knowledge I’ve gained... with my classmates at school, with people at home, and those I’ll meet in the future.”
