Pangasius Cuvier & Valenciennes, 1840

Pangasius is a genus of catfishes (order Siluriformes) of the family Pangasiidae.


In 1993, Pangasius was one of two extant genera (along with Helicophagus) in the family Pangasiidae. At this point, it was separated into four subgenera. Pangasius (Pangasianodon) included P. gigas and P. hypophthalmus and was diagnosed by the absence of mandibular barbels, the absence of teeth in adults and the presence of a single-lobed swimbladder. Pangasius (Pteropangasius) included P. micronema and P. pleurotaenia and was diagnosed by four lobes in the swimbladder and with multiple segments in the last lobe. Pangasius (Neopangasius) included P. nieuwenhuisii, P. humeralis, P. lithostoma, P. kinabatanganensis, diagnosed by palatal teeth arranged in a single large patch and high vertebral counts. Pangasius (Pangasius) was the final subgenus and had no diagnostic features, containing the remaining species.[1] These subgeneric classifications were confirmed in 2000 except for Neopangasius, found to be polyphyletic and to be part of Pangasius (Pangasius), thus leaving three subgenera.[1]

Since then, the subgenera have been variably recognized as separate. P. gigas and P. hypophthalmus have been classified in the genus Pangasianodon, and P. micronemus and P. pleurotaenia in the genus Pseudolais (with Pteropangasius as a junior synonym).[2]

In 2009, Pangasius made it onto the National Fisheries Institute’s “Top Ten” list of the most consumed seafood in America. The Top 10 is based on tonnage of fish sold. According to the NFI, this mild-flavored white-flesh fish is farmed in Asia, and is being used increasingly in food service. It is finding its way onto restaurant menus and into stores as well, where one may see it called basa, tra, or swai.

The single fossil species of this genus, P. indicus, is reported from the Tertiary period, possibly the Eocene.[2]
