Lice skirts from FiiZK can be adapted to all production conditions

By mapping our customer needs when it comes to design and durability of lice skirts, we consider key factors such as location, environment and fish welfare to optimise the best product for maximum efficiency. Our lice skirts can be tailored to the individual site, which means that we can deliver a product that makes the job for the farmers as simple as possible, while the salmon have optimal growing conditions all year round. We ensure this by offering both flow-through skirts and lice skirts with ripstop cloth. Lice skirts can be delivered enclosed or overlapping – just ask!

Lice skirt HD

Lice skirt Heavy Duty (HD) is a denser lice skirt using our Perma Skirt material (see technical report info below) that has been developed for rough sea conditions. The product is the market leader in Norway and has been tested by our customers for several years in a row with positive feedback on efficiency and durability.

• Extremely strong tarpaulin Withstands harsh weather conditions Minimal maintenance

Flow-through skirt

The Flow-through Skirt allows a continuous exchange of seawater from outside the cage to ensure optimal oxygen levels inside the cage, whilst keeping lice out. At sub-optimal oxygen levels fish growth may be negatively impacted and water chemistry undesirable for maintaining healthy livestock.

• Maintains a stable water temp Continuous water exchange Optimal O2 level Keeps lice out
