Endangered Species: Mekong Giant Catfish (Pangasianodon Gigas)

From National Geographic

Called Pla Buek in Thai, the giant catfish can weigh as much as 650 pounds (300 kilograms) and measure up to 10 feet (3 meters) in length. They are the largest scaleless freshwater fish in the world.

Chainarong Sretthachau, director of the conservation group Southeast Asia Rivers Network in Chiang Mai, Thailand, said threats to the giant catfish include commercial fishing, their touting to tourists as a food said to impart wisdom, and dynamite blasting of their spawning ground.
