Tens of 1000’s of oysters launched into the Firth of Forth seem like thriving once more after a century-long absence from the Scottish estuary on account of overfishing.
Marine consultants are “delighted” with the optimistic progress of the Restoration Forth venture, which has seen round 30,000 European flat oysters launched since September final yr.
Heriot-Watt College not too long ago led monitoring classes with divers and underwater digicam gear to verify on their standing at 4 restoration websites and has reported an 85% survival fee.
Invoice Sanderson, professor of marine biodiversity on the Edinburgh-based college, stated: “We are delighted that their high survival so far reflects the painstaking efforts we have made to support this initiative.”

Restoration Forth goals to create an oyster reef within the estuary, which in flip will present a habitat for different species equivalent to fish, crabs, sea snails and sponges.
Oysters additionally filter the water, enhancing its readability. This implies extra gentle will be capable of attain the seabed, permitting marine plants equivalent to seagrass to develop by photosynthesis.
Oysters disappeared from the realm a century in the past on account of overfishing and industrial growth.
These reintroduced to the Forth had been sourced from Little Loch Broom, close to Ullapool within the Highlands.
Companions delivering the venture embody WWF, Edinburgh Shoreline, Fife Coast and Countryside Belief, Heriot-Watt College, Marine Conservation Society, Undertaking Seagrass, Royal Botanic Backyard Edinburgh, Scottish Seabird Centre, The Ecology Centre, and The Coronary heart of Newhaven Neighborhood.
Naomi Kennon, a Heriot-Watt analysis affiliate for Restoration Forth, stated: “We have worked with hundreds of people from around the Forth to clean and move oysters to their new home.
“Working with the volunteers, over the subsequent yr we hope to see these oysters proceed to thrive and to begin to improve the biodiversity on the seabed.
“Our project will not only bring back a native species lost to overfishing in the 1800s, but also the ecosystem services those animals bring with them.
“Oysters improve water high quality by filter feeding, retailer carbon and improve biodiversity by creating a fancy habitat offering properties and shelter for numerous different organisms.”
