Four million oysters being put off Norfolk coast, to restore marine life
This is the largest oyster reef restoration project in the UK
Four million oysters are being introduced to the North Norfolk coast to help restore local marine life, today.
It's thought these molluscs will help improve water quality and create a home for a variety of other aquatic life, there.
This effort is the largest oyster reef restoration project in the UK.
By the end of 2026, 40,000 Mother Reefs are expected to be installed containing a total of four million young oysters.
The overall aim is to restore 1500 hectares - the equivalent of 3,700 football pitches – of marine habitat by 2030.
Oyster reefs generate biodiversity by providing a home for a multitude of different species and are natural water filterers, removing pollutants including excess nitrogen which helps improve water quality.
"It is essential we come together for collective restoration efforts"
Lisa Boulton, Purina Europe’s Oceans Regeneration Lead, said: “We source fish by-products for our pet food – meaning no part of the fish goes to waste while delivering valuable vitamins and minerals for pets.
“We are thrilled to be working with Oyster Heaven, marking an important step towards improving marine restoration along the Norfolk coastline and a first for Purina in the UK.
“As marine biodiversity faces significant challenges, it is essential we come together for collective restoration efforts.
“We urge other companies and organisations to work together on collaborative solutions for the benefit of ocean health.”
"Act as a foundation for the whole ecosystem"
George Birch, Founder of Oyster Heaven, explains the process: “Building an oyster reef is all about large numbers to create population tipping points and provide a suitable habitat.
“It starts with the creation of Mother Reefs, specially designed clay structures.
“Each reef is pre-charged with over a hundred baby oysters, known as spats, in a controlled environment to ensure their survival and growth.
“Local teams from Norfolk Seaweed will then carefully place the Mother Reefs on the seafloor, allowing the spat to grow into mature oysters.
“These oyster reef systems then act as a foundation for the whole ecosystem, generating an oasis of life on the seafloor."
