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!
