Building oyster reef habitats restores ocean health, protects coastlines, and creates new opportunities for industries and communities.
What happened to the oyster reefs?
100 years ago, the coasts around the North Sea were filled with oyster reefs, covering up to 30% of the ocean. The water was clear and transparent! They were just a considered just cheap food, and were overconsumed.
Today, oyster reefs in the North Sea are functionally extinct.
Oyster reefs are one of the most natural and cost-effective ways to filter the water and remove excess nitrogen pollution from the oceans. This timelapse shows 30 oysters filtering the water during 3 hours, imagine what an oyster reef can do over time!
Each oyster filters up to 200 litres of water per day
for organisations that need to keep our seas clean and clear
for organisations that rely on a healthy ocean for their supply chain
for organisations that need to protect a coastline from erosion and flooding
We’re bringing oysters back into the oceans by providing them with a new home, the Mother Reef bricks: a natural, cost effective, degradable reef.
