Basa (fish)

In 2002, the United States accused Vietnam of dumping catfish, namely P. bocourti and P. hypophthalmus, on the American market, arguing that the Vietnamese exporters, who are subsidised by Vietnam's government, constituted unfair competition.[9][10] With pressures from the U.S. catfish industry, the United States Congress passed a law in 2003 preventing the imported fish from being labelled as catfish, as well as imposing additional tariffs on the imported fish.[11] Under the U.S. Food and Drug Administration ruling, only species from the family Ictaluridae can be sold as true catfish.[3] As a result, the Vietnamese exporters of this fish now label their products sold in the U.S. as basa fish, striped pangasius, swai or bocourti.[12][13]

At the height of the "catfish war", U.S. catfish farmers and others were describing the imported catfish as an inferior product. However, Mississippi State University researchers found imported basa were preferred three-to-one to US catfish in a small (58 testers) blind taste test.[14]

Basa has become common in the UK as "Vietnamese river cobbler", "river cobbler", or "basa". It is mainly sold by large supermarkets, in both fresh and frozen forms, as a cheaper alternative to popular white fish such as cod or haddock. Young's uses it in some of its frozen fish products, under the name basa.[15] The import of basa is subject to the same stringent EU regulations as other food imports, as set out in the CBI pangasius product fact sheet[16] UK Trading Standards officers said that cobbler was being fraudulently sold as cod by some fish-and-chip retailers to take advantage of the much lower price of cobbler, which was about half that of cod. This practice was highlighted by the successful prosecution of two retailers, using DNA evidence, in 2009 and 2010.[17][18] Sometimes pangasius is described, legally, simply as "fish", as in "fish and chips".[18]
