Oysters doing well in Firth of Forth after reintroduction, say experts

Early signs of success seen in area where native European oysters were fished to local extinction by early 1900s

Thousands of oysters released into the Firth of Forth appear to be thriving again after a century-long absence from the Scottish estuary since they were lost to overfishing.

Marine experts from Heriot-Watt University who have helped reintroduce about 30,000 European flat oysters to the estuary said divers and underwater cameras showed they were doing well.
