Pangasius
''Pangasius'' is a genus of medium-large to very large shark catfishes native to freshwater in South and Southeast Asia. The term "pangasius" is sometimes used to specifically refer to the commercially important basa fish, ''P. bocourti''. ==Taxonomy== In 1993, ''Pangasius'' was one of two extant genera (along with ''Helicophagus'') in the family Pangasiidae. At this point, it was split 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. 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.〔 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). In 2011, ''Pangasius'' was sixth in the National Fisheries Institute’s “Top Ten” list of the most consumed seafood in the United States.〔(【引用サイトリンク】 title=NFI Top Ten List, a Familiar School of Fish )〕 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.
