Improved fish welfare
MarWall is the result of a collaborative project between Mørenot Aquaculture and Fiizk Protection. Together, we have developed a semi-closed system designed to reduce biological costs while enhancing fish welfare.
Benefits
Lice and jellyfish barrier at 12–18 m depth
Reduces biological costs
Significantly reduced fish handling
Better biomass growth
Lower mortality
Higher proportion of superior-quality salmon
Stable temperature
Control of water exchange and dynamics
O₂-control solution
Possibility for sludge collection
Easy installation on already existing cages
The HydrO₂ units operate completely independently and are tailored to each cage for optimal results
The flexible pumping capacity adapts to the biomass needs, ensuring continuous water exchange and a stable temperature
Lice and jellyfish barrier attached to the bottom ring
