Westcon Hexacage

Hexacage consists of closed steel cages surrounding a service cell. Each cage is operating isolated. The service cell is used for common infrastructure and machinery.

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
