Oysters caught in a river in Cornwall have won European Union protection for the name Fal oysters.
Falmouth-based Fal Oysters Ltd had to prove it uses traditional fishing methods in the River Fal.
The protected designation of origin (PDO) status gives the oysters the same name protection as Stilton cheese and Melton Mowbray pork pies.
The oysters join other EU-protected Cornish foods such as pasties and clotted cream.
"Being awarded PDO status is a massive achievement," said the firm's Chris Ranger.
"Seafood is the number one food item associated with Cornwall these days.
"This is, therefore, a really important time to make sure the heritage and quality of some of our stand-out seafood specialities is recognised too."
Cornwall Food and Drink is also trying to get the name Cornish crab protected.
