FiiZK closed waiting pens for live fish

Published 16 November 2022; updated 23 March 2026; 2-minute read. FiiZK’s patented closed waiting pens hold live fish before processing, with physical filtration and UV disinfection for water entering and leaving the pens. The page says each pen can hold up to 800 metric tonnes and aims to protect fish and the local marine environment from pathogens and sea lice.

The article explains that processing facilities may not handle each fish-farm haul immediately, so fish wait in pens where pathogens can spread to other pens, carriers and farms. Holding fish on vessels can reduce welfare and tie up vessels; unloading a haul that usually takes about an hour may stretch to half a day or longer without waiting pens. The closed system is presented as improving welfare, reducing disease transmission and speeding deliveries so carriers can perform other work such as delousing.

FiiZK was established in 2009 as a supplier of sea-lice protection equipment to Norway’s aquaculture industry and launched its first holding pen in 2015. It also supplies closed tanks for marine and land-based aquaculture. Article market context includes an estimate that ocean-derived protein could rise from 17% of global protein consumption to 40% by 2050 (historical projection).
