tagged the giant freshwater stingray and released it back into the river, expressing optimism that it remained healthy and would survive the 18-hour process from catch to release.

Hogan said that giant stingrays feed on shrimps, mollusks, and small fish on the bottom of the river, which it sucks up with its banana-shaped mouth. It is believed that the Stung Treng stretch of the river is an important pupping ground for the river’s largest fish. Hogan told NBC News, “It’s a particularly healthy stretch of the river with a lot of deep pools—pools up to 90 meters deep.
Still, Hogan pointed out how mysteries world’s biggest freshwater fish remain. He told NBC News that the catch “highlights how little we know about a lot of these giant freshwater fish. You have a fish that’s now the record holder for the world’s largest freshwater fish, and we know little about it.”
