Scientists from Wonders of the Mekong and the Fisheries Administration (FiA) have set up 36 underwater acoustic receivers along the upper reaches of the Mekong River in Cambodia to better track the movements of a stingray believed to be the largest freshwater fish ever caught, excluding beluga sturgeons, which also occupy saltwater environments.
A Cambodian fisherman caught the world’s largest recorded freshwater fish, called a giant stingray, in the Mekong river on June 13. It weighed just under 300 kilograms. Scientists called the fish “stunning.”
