What it is and how it works
The A-HSU® works by stunning the fish in water with electricity while they flow smoothly through the stun tube. The electric field in the tube makes the fish lose consciousness immediately, without any movement, struggle, or suffering.
The A-HSU® is suitable for use at the side of a lake or pond, on a farm boat or barge, and inside or outside dedicated slaughter facilities. It can be remotely adjusted for optimal results. Operational data is easily accessible for internal or external auditing through our A-FISH IQ® portal.
