Way of life
Pangasius krempfi likely spends much of its adult life in the coastal waters of the South China Sea. To spawn, the animals migrate into the Mekong from May onwards, penetrating at least as far as the Mekong Falls . The eggs are mainly laid between June and August, the young animals then drift down the Mekong with the current. The diet is unknown, but plant material is likely to be consumed in the Mekong.
