The water replacement system and the deep lice skirts provide a positive aquatic environment in the fish cage. Oxygen-rich water is pulled in from water depths free from sea lice and algae, and circulated in the cage. This is believed to improve fish health, increase growth rate, lower feed factor, improve colouring and produce firmer fish fillets.
The sea lice count in Aquatraz G3 is low and decreasing (without treatment). G3 has a total lice skirts of 18 meters, where the upper 8 meter are of steel and the bottom 10 meter of impermeable tarpaulin.
Safeguarding against escape and secure abundant supply of sea lice free water facilitates a substantial increase in the fish density inside the cage.
The raiseable steel structure with wide walkways and handrails provides improved working conditions with less heavy lifting, and decreased reliance on support vessels. Aquatraz has a design life of 20 years with low operating and maintenance costs. The fish cage has a lifting system ensuring that the cage can be lifted out of water for cleaning, disinfecting and maintenance on site.
The second generation Aquatraz – G2, has a new electric lifting system that allows for lifting and lowering without relying on energy supply from a boat. It has wider walkways with heated storage containers and several other improvements that is still part of the newer generations.
