We are here to help oysters help us

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 considered just cheap food, and were overconsumed.

Today, oyster reefs in the North Sea are functionally extinct.

Today

What makes oyster reefs so important for the health of our oceans?

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

Oysters aren’t just food—they’re nature’s quiet builders.

Nature knows how to recover. We’re giving it the space to do it.

Our reefs help bring life back to the sea: cleaner water, safer coastlines, and flourishing marine habitats. We plant the foundation; nature does the rest. Together, we can give the ocean the space it needs to heal—and thrive once more.

How do we build oyster reef habitats?

Meet The "Mother Reef"

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.
