A fisherman in northern Cambodia hooked what researchers say is the world’s largest freshwater fish — a giant stingray that scientists know relatively little about.
The fisherman, 42, caught the 661-pound fish — which measured about 13 feet in length — near a remote island on the Mekong River in the Stung Treng area. A team of scientists from the Wonders of Mekong research project helped tag, measure and weigh the ray before it was released back into the river. The research group believes it was healthy when released and expects it to survive.
The tag — which emits an acoustic signal — will allow researchers to track the fish’s movements and, they hope, learn more about its species’ behavior in the Mekong.
The catch “highlights how little we know about a lot of these giant freshwater fish,” said Zeb Hogan, a fish biologist at the University of Nevada. “You have a fish that’s now the record holder for the world’s largest freshwater fish, and we know little about it.”
The fisherman, Moul Thun, caught the giant stingray with a hook and line on the evening of June 13, and then contacted researchers the next morning.
Researchers with the Wonders of Mekong were already in northern Cambodia to install underwater receivers as part of a project to track migratory fish in the river.
“It’s a particularly healthy stretch of the river with a lot of deep pools — pools up to 90 meters deep,” said Hogan, who is also the host of National Geographic’s “Monster Fish” television series. “We started focusing on this area as a stretch of river that’s particularly important for biodiversity and fisheries, and as a last refuge for these big species.” Read more from NBC.
