Adressing 5 frequent questions.

Who is cerberus seaweed systems for?

Cerberus is designed for small-scale farmers, researchers, and anyone who wants to start with algae cultivation in coastal areas.

Can I expand my setup later?

Absolutely! cerberus' modular design lets you start small and add more units as you grow. It can be also easily integrated into existing Farm infrastructures or transitions into a more conventional farm later on by adding the cages onto the lines.

What type of algae can
I grow?

The system with our cages supports a variety of shorter algae species, e.g. Ulva. Since march 2025, we have proven, that larger algae, such as sugar kelp grow well on our systems. If you want to be among the first testers with sugar kelp, feel free to contact us!

Is it difficult to set up?

Our system was designed for easy setup and integration. Nonetheless depending on your location and preexisting or non existing infrastructure, level of setup can vary. We can gladly help you out!

Why is seaweed farming important?

Seaweed is a sustainable super-resource that helps the environment and supports a growing blue economy. Currently, most of our algae, which is used in yoghurt, ice cream, vegan sausage....you name it, is imported from Asia or Africa. We want to spread more awareness in Europe about seaweed farming, because we can build up our own resources here, too! There are so many great European algae species to grow and harvest. It makes only sense to farm more on water on our water planet.
