Sea farm for Belgian mussels

With an innovative sea farm off the Belgian coast, Sea farm Westdiep, aims to meet the growing demand for sustainable protein-rich food. Research has shown that the Belgian North Sea is suitable for cultivating mussels. With the necessary permits, we started building the first commercial sea farm in Belgium.

First commercial sea farm in Belgium

As a retailer, we are actively working on innovative solutions to meet the growing demand for balanced and sustainable protein sources. In that context, we also strongly believe in the potential of the Belgian North Sea for the local cultivation of mussels, oysters and seaweed. In early 2022, we started developing the first commercial sea farm off the Belgian coast: sea farm Westdiep. A project that will benefit both biodiversity and employment.  

Off the Belgian West Coast

Sea farm Westdiep is located off the coast of Nieuwpoort and Koksijde in project zone C, as foreseen in the Marine Spatial Plan. In the start-up phase, we will only use a quarter of this zone. The zone is particularly well suited for the production of mussels, oysters and seaweed thanks to the presence of numerous nutrients and the good water quality. To ensure the safety of all boats, the sea farm is clearly demarcated and we installed a safety platform that monitors 24/7 traffic at sea in Zone C.

Eco-friendly aquaculture

The cultivation of mussels, seaweed and oysters at open sea is an extractive form of aquaculture in which the shellfish obtain their nutrients from the seawater and nothing is added to the ecosystem. Moreover, a marine farm can serve as a refuge for fish and other marine life, as fishing and recreational boating are prohibited within the zone. This promotes biodiversity in the Belgian North Sea. Cultivation of mussels uses long line or ‘hanging culture’ technology: culture structures that are attached to strongly anchored ropes and buoys under water and that sway along with the sea current. 

Belgian mussels in the store

We expect to take part in a first Belgian mussel season in the summer of 2023. In the meantime, we are also investigating the feasibility of cultivating seaweed and oysters, both of which are nutritious and sustainable sources of protein.
