Oysters released in Conwy marina to save species in area
More than 1,000 oysters have been released in north Wales to try to stop the species dying out in the area.
The shellfish were once a major part of Wales' fishing industry.
Now they have been placed in nursery cages under the boardwalks of Conwy marina.
Conservationists hope they will help reverse the impact of over-fishing and water quality on the species.
