It can grow up to 2 m in length and weigh up to 150 kg (330 lb). It has been used as food in Southeast Asia since ancient times. Overfishing for its prized meat has caused the population to significantly decrease. Furthermore, the breeding migration pattern of this fish is especially vulnerable to damming, which has also decreased the wild population significantly.

Mystus atrifasciatus is a species of catfish endemic to Cambodia, Laos, Thailand and Vietnam, known from Mekong River, Chao Phraya River and Mae Klong River and was described from Phitsanulok, Thailand.

It feeds on crustaceans and zooplankton along with some algae and fish scales. It is commonly fished and marketed and is also found in the aquarium trade. It may be threatened by pollution and overfishing and more research is needed about the species.
