"So, to gain that information about individuals, that's going to be really critical to promote the conservation of the species. The largest freshwater fish is the Beluga Sturgeon. The 8.9 foot long Mekong giant catfish was the. "This is going to allow us that first, kind of empirical data to gain that information about those individual migratory patterns of fish," Hogan said in a video released by Wonders of Mekong.

Hydroelectric development projects may be in store for locations along the Mekong, Hogan told NBC, and learning about the fish's migratory needs is important to ensure that any future projects don't threaten the stingrays.
The researchers also tagged this stingray with an acoustic transmitter that will help the scientists keep tabs on the monster fish for a full year. Wonders of Mekong pays fishers market price for their released catches. All three stingrays, including a 397-pounder (180 kg) caught in May, were female, raising the possibility that this stretch of river might be a nursery where stingrays go to lay eggs and raise young. A fisherman in northern Cambodia hooked what researchers say is the world’s largest freshwater fish a giant stingray that scientists know relatively little. 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.
This is the third giant stingray catch-and-release of the last two months, according to NBC. Scientists present at the capture have estimated the Giant freshwater Stingray to weigh an incredible 265kg+, making it the largest freshwater fish ever landed on rod and line Whilst fishing with Dr.Zeb Hogan and the National Geographic production crew the Fishsiam team successfully captured and released sixteen different Giant freshwater. 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.
