Biologie     Glossaire (ex. epibenthic)

Migrating but the direction is unknown. Dietary habits have not been studied. Taxonomy of this species may be problematic (Ref. 12693). Unique among pangasiid species in the Mekong in spending a major part of its life in marine coastal waters. Migrates into the Mekong River (but not into any other rivers) in order to breed (Ref. 12369). Regarded to be anadromous (Ref. 12369). It was hypothesized that at least two populations in the Mekong undertake migration (Ref. 37770). One population migrates during May-September from just south of Khone Falls upstream to spawning grounds along the mainstream Mekong all the way to Chiang Khong near the Lao-Thai-Myanmar border. The other population migrates downstream from around Stung Treng to unknown spawning grounds somewhere between Stung Treng and Kompong Cham in Cambodia during the spawning season between May and August. When water level starts to fall in October, the fish moves back to the main river to initiate an upstream dispersal migration, reaching the stretch just below the Khone Falls. Stays in deep pools within the mainstream during the dry season (Ref. 37770). Only two specimens of the fish were collected on April 5, 1956 and September 10, 1957 in Beihai City, Guangxi (Ref. 45563). Another on November 22, 1963 at Shanwei City of Guangdong Province (Ref. 45563).
