Story told by Samel Muren

Onnest is proud to finally reveal the design of our new facility, drawn by architects Hovaldt, Lendager and Schönherr.

With Onnest Blue Garden, we want to show that the future of food production can be both highly advanced and in perfect harmony with nature. Our ambition goes far beyond just producing top-quality trout; we want to create a facility where water, energy, and nutrients exist in acontinuous, smart loop, making the absolute best use of every resource.

To bring this vision to life, we chose an architect-designed building. We wanted a physical space that visually tells our story and captures what we stand for. Our goal is to create a landmark that the local community in Hirtshals can be truly proud of – a building that sparkscuriosity and feels warm, open, and welcoming to everyone who visits. We are setting a new standard for responsible food production, starting right here in Hirtshals, with a vision that reaches far beyond Denmark's borders.

Advisors chosen

In the development of the Onnest aquaculture project, combining and pairing different, but still leading knowledge and competencies, are the key to success. Our prime focus will be sustainable and circular aquaculture where biology and fish welfare are at the core of what we do, future-proofing our products and practices for tomorrow’s consumer.

Onnest have now found its home

We are doing aquaculture on land and not in the sea. The fish farming industry has taken major technological steps the last decade or so, enabling large volumes of fish to be farmed on land. By doing this, we can improve fish welfare aspects since we can control the environment the trout lives in.
