Our Technology: The Mother Reef

The fastest way to regrow lost oyster reefs

Meet The Mother Reef

The heart of our model is our technology, the Mother Reef. 

The Mother Reef bricks are the most cost-efficient substrate for oyster regeneration. They are the essential scaffolding to cover the deserted sea floor and support oysters as they grow into fully formed self-sustaining reefs. We pre-charge them with at least 50 oysters each before we plant them into our oceans.

Mother Reefs covered with spats and baby oysters:

Science based. Succesfully tested.

Science is at the core of everything we do.

We have conducted extensive research and partnered with the best scientists to find the most effective methods for restoring oyster reefs. Our Mother Reef technology has undergone rigorous testing in both lab and ocean settings in collaboration with DTU Aqua in Denmark with successful results and we are constantly working on improving our technology.

On land larvae settlement

We do larvae settlement on land to ensure the survival and growth of baby oysters in a controlled environment before deployment into the sea.

Manufactured anywhere in the world

The Mother Reefs are produced in traditional brick factories, so we can produce them cheaply and anywhere in the world.

Production is rapid. One extrusion machine can produce 40.000 Mother Reefs per day!

We partner with local fishermen to plant the reefs in the water

Our projects can be deployed anywhere in the world where oyster restoration is needed. We partner with local fishing communities and provide them with a new revenue stream and type of work.

Fishermen will use their boats, equipment and knowledge of the water to plant the Mother Reefs into the ocean. They will also benefit from the improvement of the ocean health and biodiversity.

From Molecular to Marine: My journey into Oyster Heaven Four Questions for Natanael

With a scientific approach at its core, Oyster Heaven is dedicated to thoroughly mapping out the process of oyster reef recovery. Due to the scarcity of large, thriving flat oyster reefs in Europe, our understanding relies heavily on compiled research, comparative studies, and modeling. To accurately assess the full impact of oyster reefs, our research team studies various aspects of oyster reefs. Introducing Natanael, who made the leap from biological fields to delve into the microbiological dynamics of marine environments. Joining Oyster Heaven, he focuses on understanding the nutrient management capacity of oyster reefs.

Time to meet Oyster Heaven’s team: Four questions for our founder, George

As we work hard to implement our approach to oyster reef restoration in the Netherlands and the UK, we are also filling up our project pipeline to initiate even more reefs to steadily bring back the lost oyster reefs in our European waters and beyond. With our workload growing, our team expanding, and our outreach broadening, it’s time to introduce the dedicated individuals who’ve been working tirelessly behind the scenes. Let’s begin with our founder, George, the visionary driving force behind it all…

Clay: A Time-Tested Solution for Oyster Restoration

In the world of marine conservation, the search for effective materials to aid restoration is a never-ending exploration. For oyster reefs specifically, the need for a suitable substrate is the key in achieving reef revitalisation. Among the many materials, clay stands out as a tested solution which has led us at Oyster Heaven to use it as the preferred material to kick start large-scale oyster reefs.

Purina Europe launches its first Ocean Restoration Programme, aiming to restore 1,500 hectares of marine habitats by 2030

28 February 2024, ROTTERDAM: The ocean is essential for all life on Earth. However, as a result of climate change and human activities, ocean health is declining at an alarming rate, putting all marine life under threat. To ensure a sustainable future, our oceans must be protected and preserved. That is why Nestlé Purina PetCare Europe is launching its first Ocean Restoration Programme, to help tackle marine biodiversity loss in Europe.

The connection between oysters, seagrass and seaweed

Every ecosystem is made up of different species interacting with each other in different ways. We are quite familiar with the predator/prey relationship that ensures the balance in the food web as a means of protection. A good example is the key role of sharks in controlling the number of sea turtles that could otherwise impact seagrass on which they feed.

Optimising Oyster Restoration With Science and Research

To optimise how oyster restoration can be done, we’ve looked into what worked so far and what didn’t succeed and conducted laboratory and field testing.

After two years of dedicated work, we’ve identified these are the key factors to optimise oyster restoration.
