Basa in The UK
Basa has become fairly common in the UK under the name "Vietnamese river cobbler" or just "river cobbler". It is 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.
UK Trading Standards officers have stated cobbler is being fraudulently sold as cod by some fish and chip retailers 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.
