UK fish and chip shops are selling endangered sharks, DNA tests prove

People buying generic fish such as rock could in fact be eating a range of shark species

Fish and chip shops and fishmongers are selling endangered sharks to an unwitting public, according to researchers who used DNA barcoding to identify species on sale.

Most chip shop fish sold under generic names such as huss, rock, flake and rock salmon turned out to be spiny dogfish, a shark species classified as endangered in Europe by the International Union for the Conservation of Nature's red list.
