FiiZK enclosed marine fish-farming pens

Published 16 November 2022; updated 23 March 2026; 2-minute read. FiiZK supplies fully enclosed marine fish pens intended to prevent parasite/pathogen exposure, fish escapes and emissions to nearby waters. Durable PVC cages are designed for high winds and waves; pumps draw water from depths of at least 15 m, and filtration treats incoming and outgoing water. Sizes are configurable; the largest listed capacity is 15,000 m³.

The article says closed pens can support fish welfare and produce larger, faster-growing, higher-quality fish. It contrasts reported biomass loss of up to 20% in traditional open farms with loss seldom above 1.5% in closed farms. The systems are presented as addressing disease, sea lice, escapes and seabed accumulation of waste/feed.

FiiZK was established in 2009 and also supplies closed waiting pens and closed cages for land-based aquaculture. The article states that 40% of global protein consumption is expected to come from the sea by 2050; this is a projection. Availability: available. Category: aquaculture and fisheries.
