Cladus: Eukaryota Name Pangasius bocourti Sauvage, 1880 Vernacular names
The basa fish, Pangasius bocourti, is a type of catfish in the family Pangasiidae. Basa are native to the Mekong River Delta in Vietnam and Chao Phraya basin in Thailand.[1] These fish are important food fish with an international market. They are often labeled in North America and Australia as basa fish or bocourti.[2] In the UK, the species is known mainly as river cobbler,[3] with basa also being used on occasion. In Europe, these fish are commonly marketed as pangassius or panga.[4] Other related shark catfish may occasionally be falsely labeled as basa fish, including Pangasius hypophthalmus (iridescent shark) and Pangasius pangasius (yellowtail catfish). Body The body of a basa fish is stout and heavy. The rounded head is broader than it is long, the blunt snout having a white band on its muzzle. Food and Spawning Basa fish feed on plants. They spawn at the onset of flood season and the young are first seen in June, averaging about 5 cm by mid-June.[1] Toxins There has recently been an unsubstantiated report into high toxin, pesticide and cancer issues concerning Basa from mass farming techniques on the Mekong River in Vietnam. Tests by ASDA and Tesco in the UK have found no trace of contaminants.

However, researchers at the Mississippi State University show that in their experiment, imported basa were preferred in a taste test 3-to-1.[12] Mascot P. bocourti, known in Thai as pla mong, is the mascot of Nakhon Phanom Games, a regional multi-sport event in central Thailand in October 2006.[13] Basa in the UK Basa has become fairly common in the UK under the name Vietnamese river cobbler, mainly being sold through the large supermarkets in both fresh and frozen forms. It is marketed as a cheaper alternative to traditionally popular white fish, such as cod or haddock. Young's Bluecrest use it in some of their frozen fish products, choosing to use the name basa instead of cobbler. It has also been stated by UK Trading Standards officers that cobbler is being fraudulently sold as cod by some fish and chip retailers in order to capitalise on the large difference in the wholesale price between the two i.e. cobbler costs less than half the price of cod. This practice was highlighted by the successful prosecution of two retailers (using DNA evidence) one in July 2009 and another in April 2010.[14][15] References 1. ^ a b Froese, Rainer, and Daniel Pauly, eds.
