Building a Blue Future: The Story Behind Wales’ First Regenerative Seaweed and Shellfish Farm

Car-Y-M?r is a community of people using regenerative ocean farming, food security and sustainable job creation to improve the coastal environment and wellbeing of the local community. Its zero input farming uses no fertilisers, pesticides, or freshwater. They aim to stimulate jobs and give people a route into the Welsh seafood sector, an industry that is growing within Wales.

Co-founder Fran?ois Beyers talks with us about his motivations behind Car-Y-M?r , regenerative aquaculture, and his hopes for the future.

What motivated you to start Car-Y-M?r??

The primary motivation behind founding Car-Y-M?r was a passion for marine conservation and a desire to address the pressing issues facing our coastal ecosystems. With varied?backgrounds, we were driven to create sustainable seafood solutions that benefit both the environment and the community.

How have these motivations developed into a community-owned business?

From the outset, we recognised the importance of involving the community in our mission. Car-Y-M?r operates as a community benefit society, which means we're owned by and operated for the benefit of those who believe in our cause. This structure has allowed us to ensure that our operations remain focused on enhancing local well-being and environmental health, rather than prioritising profit.

What makes your process regenerative?

Our process is regenerative because it actively contributes to the health of the marine ecosystem. We use zero-input farming methods — no fertilisers, pesticides, or freshwater. This approach not only minimises environmental impact but also helps restore the natural balance of the coastal waters, encouraging biodiversity and helping to rebuild marine habitats.

Tell us more about the seaweed biostimulant — how did that come about?

The idea for our seaweed biostimulant emerged from our ongoing research into sustainable aquaculture practices. We discovered that seaweed, which we were already farming, had properties that could benefit plant growth. This led us to develop a biostimulant that aids in plant resilience and growth, turning a by-product of our aquaculture into a valuable resource for agriculture.

What were some unexpected discoveries during the process?

One of the most unexpected discoveries was the wide range of additional uses for seaweed beyond just food. From its application in biostimulants to its potential in bioplastics and as a nutrient-rich feed for livestock, seaweed has shown itself to be incredibly versatile and a key player in circular economy solutions.

Do you think “regenerative” is the answer to our food security, climate, and biodiversity crisis?

Absolutely, regenerative practices represent a profound shift in how we approach agriculture and aquaculture. They not only mitigate damage but actively improve ecosystems, which can help address multiple global crises — from food security and climate change to biodiversity loss — simultaneously.

What changes in the seafood farming sector have you noticed over the years now that you’ve introduced a sustainable and innovative approach to aquaculture with Car-Y-M?r?

Since introducing our sustainable practices, we've noticed a growing interest in regenerative methods across the sector. More businesses are exploring how they can reduce inputs and enhance the ecosystems in which they operate. There’s a growing recognition that sustainability isn’t just a niche market but a crucial element of future-proofing the seafood industry.

Why do you do what you do?

We do what we do because we believe in making a difference. We're not just farming seaweed and shellfish; we're fostering a healthier coastline and community. It's about showing that business can be a force for good, that economic activity can go hand-in-hand with conservation and community benefits. As a dad, I feel a deep responsibility to leave behind a healthier world for future generations. Our efforts at Car-Y-M?r are not just for today’s communities but for ensuring that our children and their children inherit a world where they can thrive.

What are your hopes for the future?

Our hope for the future is to see regenerative aquaculture become the norm rather than the exception. We aim to expand our impact, inspire more initiatives like ours, and continue to innovate in ways that restore and preserve our marine environments for future generations.
