Closed pens

Closed & semi-closed farming

The controlled environments of fully closed and semi-closed pens allow farmers to safeguard production against external biological and environmental threats. At the same time, continuous monitoring with our solution ensures that fish welfare and growth conditions are closely tracked, reducing risks during production and providing early warnings if something goes wrong.

Providing an extra layer of security

While closed and semi-closed pens provide greater control over biological risks such as lice, jellyfish, and algae, success still depends on having insight into both key environmental factors and fish condition. Our cameras and systems are deployed across most shielded pen technologies, delivering continuous monitoring of weight, welfare, and behavior – as well as confirming that lice-preventive measures are working as intended. Built-in camera sensors that monitor oxygen levels, salinity, and water temperature provides an extra layer of security when mechanical systems are used for water exchange.
