1,300 native oysters have been returned to waters in River Conwy as part of an ambitious restoration project to bring back these 鈥榦cean superheroes鈥 from the brink of extinction. The Wild Oysters Project, a partnership between ZSL (Zoological Society of London), Blue Marine Foundation (BLUE) and British Marine aims to help restore healthy, resilient coastal waters around the UK.
Earning themselves the title 鈥榦cean superheroes鈥, native oysters (Ostrea edulis) provide huge benefits to coastal waters by helping to clean our seas and acting as an important habitat for marine wildlife. Declining by 95% due to human activities, native oyster populations have continued to decrease since the 1800s, meaning their benefits to the ocean have been lost.
In a bid to restore native oyster populations, and in turn see the return of health coastal waters, nurseries filled with oysters will be suspended underneath marina pontoons in Conwy Marina and Deganwy Marina of the River Conwy. The nurseries create a micro habitat acting as a maternity ward to the next generation of oysters. These oysters will begin reproducing over the next few months, releasing millions of baby oysters, known as larvae, into the ocean.
The perfect location to restore native oysters
鈥淐onway Bay is a designated Special Area of Conservation with unique underwater habitats and important marine plants and wildlife, making it into protective nurseries to help habitats thrive.鈥
鈥淣ow the oysters are in their new home in the marinas, they will almost immediately begin their important work each filtering 200 litres of water a day. In the coming months the oysters will start to produce the next generation of the oyster population, by releasing larvae which will then be carried out by the water hydrodynamics and settle onto the seabed. In turn we hope that the project will help to create cleaner water, healthier fisheries and plentiful marine biodiversity鈥痠n Britain,鈥 explained Celine Gamble, Wild Oysters Project Manager, ZSL.
The project has partnered locally with the School of Ocean Sciences at 成人VR视频, a local project officer will help to monitor and care for the newly placed oysters as part of The Wild Oysters Project.
鈥淣ative oyster populations, local to Conway Bay in the Menai Strait near Caernarfon and Bangor, were highly prevalent in 18th and 19th century, with Welsh oyster boats reportedly landing 8,000 oysters daily. We know that oysters once thrived in the local area, forming an important part of the local marine ecosystem, now we have the opportunity to restore native oyster populations which will provide important ecosystem services.鈥
鈥淭hanks to鈥痯layers of鈥疨eople's Postcode Lottery we hope to see healthy, resilient, coastal waters in Conway Bay and make a remarkable difference to the future of鈥痺ild鈥痮ysters. They are the superheroes of our oceans,鈥 said Local Project Officer for the Wild Oysters Project, Maria Hayden-Hughes.
The project, which spans the UK, has now installed 94 of 141 planned nurseries underneath marina pontoons across Wales and North East of England.
Laura Chow, Head of Charities at People鈥檚 Postcode Lottery, said: 鈥淲ith just a few known native oyster populations remaining in Wales the release of the project鈥檚 native oysters into Conway Bay marinas is a huge milestone, all possible thanks to the support of players of People鈥檚 Postcode Lottery. Oysters are an important part of our ecosystem and the Wild Oysters project will not only support our oceans but help educate and share the importance of these ocean superheroes with thousands of volunteers, school and university students, and local community groups.鈥
The Wild Oysters project, a three-year ambition, was awarded 拢1.18m by the Postcode Dream Trust. The Dream Fund, run by Postcode Dream Trust, gives organisations the opportunity to bring ambitious, innovative and collaborative projects to life.
BLUE鈥檚 Senior UK Projects Manager Morven Robertson said, 鈥淚t is vital in the current climate emergency and biodiversity crisis that nature receives the help it needs to bounce back. The Wild Oysters project will give the marine environment a chance to recover, which is not only important for nature and climate, but also the people that rely on it.鈥
British Marine Environment Executive, James Scott-Anderson, said; 鈥淭o have the direct involvement of marinas as part of this project is enabling the industry to become more sustainable, and playing a key part in the future of our oceans. To have these sites in Wales, with local community involvement, is part of this unique partnership and a big step on the road to restoring native oysters in the UK.鈥
The Wild Oysters Project will deploy the final 1,300 oysters in Scotland in the coming weeks to continue to support the restoration of oysters. For more information visit .
