Control your cage environment.

FiiZK designs and delivers closed cages adapted to your requirements for post smolt, brood stock fish and harvesting cages. Research from scientific trials and commercial-scale production has shown better growth and close to zero lice compared to open-net reference cages. In Jauary 2022, we merged our expertise with Ecomerden in semi- closed and closed containment technology. During 2022, we will deliver 12 closed facilities at sea - this corresponds to a total of 200,000m3 of shielded production volume!


Certus 10000 – 30000 Semi-closed containment systems (S-CCS), where an impervious barrier surrounds cultured salmonids to separate them from their external environment, are an important addition to open-net cage farming at sea to aid in ambitions to increase aquaculture production volumes, reduce risk of escapes and eliminate sea lice pressures. For over 10 years, FiiZK […]
