A recent study reveals that many UK fish and chip shops mislead customers by selling catfish instead of traditional options like cod and haddock. DNA testing confirmed that several takeaways advertised as serving ‘fish’ were actually selling catfish.
Key statistics:
Around 380 million meals are served annually by fish and chip shops in Britain. and 6,800 pounds of blue catfish were landed through electrofishing in Maryland.
Professor Stefano Mariani noted, “In my experience with fish and chips, three out of 10 is quite a lot – I don’t recall seeing this level of catfish.” Many customers expect to receive marine species such as cod or haddock when ordering.
Maryland is currently studying the use of gill nets for commercial harvesting of invasive blue catfish. This species poses a threat to native species in the Chesapeake Bay, particularly blue crab. The Maryland Department of Natural Resources is evaluating bycatch risks associated with gill nets.
Maryland’s Invasive Blue Catfish Pilot Program aims to shift public perception and build markets for blue catfish. Eating catfish is considered safe and a good source of protein. However, fish and chip shops should list the species of fish on their menus to maintain public trust.
