The genus Pangasianodon from the shark catfish family includes two species : P. hypophthalmus (" Pangasius ") and P. gigas (" Mekong giant catfish "). Both occur exclusively in the Mekong and its tributaries and are fished, which threatens the wild stocks. While P. hypophthalmus is also one of the most important aquaculture fish in Southeast Asia, the first attempts to cultivate P. gigas have only just begun.
The genus Pangasianodon was separated from the genus Pangasius due to morphological and molecular differences, but is sometimes still listed as a subgenus. In addition to the typical physique of the shark catfish with a scaly, elongated body, short dorsal fin with spines and long anal fin, the species Pangasianodon has a number of characteristics: The barbels on the lower jaw are absent, as are the teeth in the terminal mouth in the adult stage. The ventral fin has 8 to 9 rays and the swim bladder is single-lobed.
