Fish welfare with no moving parts

Everything we build rests on the same principle.

The fish pass through a controlled channel at a known speed, a known distance and a known orientation. Everything else follows from that.

The route through the system.

Five steps from dirty to clean sector. The water flow carries the fish the whole way.

Model of the system, seen from the side

  1. 01

    Dirty sector

    The pen is divided into sectors. The fish gather gently in the untreated sector — no winch, and no starving them into place.

  2. 02

    Suction inlet

    The water flow carries the fish into the channel. No mechanical part touches them.

  3. 03

    PCLD

    Controlled passage past camera and laser. Speed, distance and orientation are known here — and every fish passes.

  4. 04

    Clean sector

    The destination: a sector that only treated fish enter. The separation holds throughout the operation.

  5. 05

    PCLD outlet

    The fish are released into the clean sector and swim on by themselves.

Three systems, one channel

The parts can be used on their own, but they are designed to work together.

  1. 01

    Sector control

    The pen is divided into sectors and the fish are moved gently between them. It replaces today's practice of starving the fish to get them where you want them.

  2. 02

    Ejector transport

    Live fish are lifted and moved by water flow alone. No impeller, no pinch points, no moving parts in contact with the fish.

  3. 03

    PCLD delousing

    Predictive Channel-Based Laser Delousing. Channel-based laser treatment under controlled passage: the camera finds the lice, the laser treats, the fish moves on.

Injector

The injector is our existing product outside aquaculture, with applications in transport and shipping. The principle is the same as in the channel: the water flow does the work, with no mechanical parts touching what is being moved.

Where we stand

  • A patent application has been filed, and the technology has been assessed against existing patents.
  • The flow is documented through CFD simulations.
  • Prototypes have been built and tested in the laboratory.
  • Development continues in an ongoing project with testing under realistic conditions.
