What it is and how it works
The A-HSU™ is an innovative, high-performance fish stunner perfect for harvesting bass and bream. It features a stun tube under the boat deck, keeping valuable deck space clear for harvest tubs.
The fish are directly pumped from the sea into the stunner tube through a centrifugal pump. Electrodes embedded into the interior of the stunner pass an electrical current through the water and the fish. The electrical contact between the fish and water ensures that all fish, regardless of size, are stunned reliably and without pre-stun shocks. The tube then rises high above the deck to allow a chute to direct fish into the correct ice-filled tub.
The A-HSU™ creates a calm harvesting environment and improves slaughter welfare without compromising quality or harvest rates.
