Oysters extinct for over a century back in Dornoch Firth

Description

Oysters are being re-introduced to the Dornoch Firth in the Highlands over a century after they were fished to extinction.

For tens of thousands of years until the late 1800s there were huge amounts of oysters in the waters.

Now, for the first time anywhere in Europe, entire reefs are being created from waste scallop shells and more than 20,000 oysters will be placed inside.
