sustainable concept
for closed fish farming
at sea

Hexacage's goals

• A marine steel structure with sea characteristics, protection and life time as for vessel
• Fully control in-water by filtering all water in, secure water volume and control the current within the cage
• Eliminates all stress inducing operations
• Hexacage is thoroughly sustainable within biology, environment and energy
• Hexacage enables industrialized fish farming in closed cages
• Hexacage's facilities ensures a healthy and stress-free growth of the fish

‍

Key features with biological focus

• All in-water filtered to remove lice,
  laerve and eggs.
• Flexible in-water system to take water
  from temperatur favorable depth.
• Controlled hydraulic in cage to
  optimize current to fish size.
• Fish transfer to another cage or vessel without pumping
• Crowding with less stress

‍

Biological gains

• No escape - no predators
• No lice or lice treatment
• No net cleaning
• No use of cleaner fish
• Improved biological performance
• Mortality expected <4% /year
