This stingray (Himantura Chaophraya) measured 4.2 meters in length and was too massive to weigh. Reported to grow to 1,000 pounds, this fish is the largest that I've seen in the Mekong River. For the 2004 project, we hope to include the freshwater stingray and other giant fish species such as the freshwater sawfish, freshwater sharks, and infamous "dog-eating" catfish (Pangasius sanitwongsei).
