Optimal Fish Rearing Environment where the salmon can grow faster and the problems with lice and escape are eliminated

BETTER FISHWELFARE

  • Fresh water is pumped continuously so that the fish do not have to stay in stagnant water.

  • The pumping provides a water flow that gives the fish exercise, which leads to a slightly firmer meat on the fish. A stronger fish is more resistant to disease.

  • The water is pumped from a depth where there is usually no salmon lice. If, nevertheless, lice manages to enter the cage, they will not be able to settle, but will die out without any need for treatment of the fish. This avoids the frequent lice treatments that leads to poor animal welfare and high mortality rates.

  • The oxygen level is monitored and can be adjusted if necessary. 

  • Lower mortality rates than in open net-cages.

INCREASED SUSTAINABILITY

  • Waste from the closed cages can be collected to prevent it from ending up in the surrounding environment.

  • The waste can be recycled and for example used as fuel, manure or in cement production.

  • Minimizes the risk of escapes.

BETTER ECONOMY

  • The cages have a lifecycle of more than 20 years (certified)

  • Low maintenance.

  • Low mortality rate.

  • No or minimal costs for delousing.

  • Lower feed factor.

  • Low production costs.

  • Faster growth. 

  • As the water is pumped from the depths, the average temperature can be kept at a higher level also during the winter. This means that the fish can grow over a longer period of time and farming can take place all year round, even in colder regions.

  • Reduced production time.
