Sustainable cultivation in the North Sea

Innovative longline systems

The cultivation of mussels and oysters in the open sea is an extractive form of aquaculture. This means that the shellfish get their nutrients from the seawater, so nothing is added to the ecosystem. Moreover, a sea farm can serve as a shelter for fish and other marine life. In this way we promote biodiversity in the Belgian North Sea.
Cultivation takes place using longline or ‘hanging’ technology, whereby a rope is attached underwater to buoys and strong anchors. Below this, mussel ropes are attached to which the mussel seed attaches itself and continues to grow.

Belgian mussels

Why import mussels when we can grow them ourselves in our own North Sea?
Together with our Belgian partners, we are joining forces to develop the first sea farm and thus bring the first Belgian mussel to your plate.
