Amazing facts-Giant catfish

Fishers in northern Thailand netted this huge catfish in the Mekong River on May 1. Nearly nine feet long (2.7 meters) and as big as a grizzly bear, the behemoth tipped the scales at 646 pounds (293 kilograms). Experts say the fish, which belongs to the species known as the Mekong giant catfish, may be the largest freshwater fish ever recorded.

Officials from Thailand's Inland Fishery Department then used a performance-enhancing drug to stimulate the pituitary gland of the female fish in order to prepare it for a breeding program (above). Despite efforts to keep the bear-size catfish alive, it died and was later eaten by villagers.The species is listed as critically endangered by the World Conservation Union (IUCN) and faces a high risk of extinction in the wild. The rare specimen, captured in the Mekong River in Chiang Khong district, is the largest since Thailand began keeping records in 1981.

But the whopping fish, which was as big a grizzly bear, didn't survive.Listed a critically endangered by the World Conservation Union (IUCN), the Mekong giant catfish is one of the world's largest freshwater fishes. Other contenders include the Chinese paddlefish and the dog-eating catfish—another Mekong River giant.
