In brief

Abyss has developed expertise in service for submersible nets that protect fish from salmon lice.

New shielding technology using submersible nets is gaining ground in aquaculture. Abyss has had service vessels working at these farms since April 2025.

An important part of innovative technology

The pens are lowered to around 30 metres to protect fish from salmon lice in the upper water layers. Handling and maintaining the nets is essential for biosecurity and fish health.

Raising and lowering nets

These assignments require vessels with good crane and winch capacity. Divers inspect the nets before they are raised, the roof is removed, and cleaning and delousing are carried out. The nets are then lowered again.

Benefits of submersible nets

The technology can reduce lice pressure and the need for treatment, and improve fish welfare, while work and maintenance are carried out with a high level of safety above and below the water.
