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, and you can check the operational data at any time.
The A-HSU™ for freshwater trout creates a calm harvesting environment, improving welfare at slaughter and processing rates at harvesting.

“We chose the Ace Aquatec Stunner because it was an in-line system where fish can stay in the water so there’s very little stress. It’s helped us humanely harvest fish in a safe and productive way. Blood spotting has also diminished to sub 1% which is pretty incredible.”
