What it is and how it works

A-HCS® is an innovative system that uses our award-winning Humane Stunner Universal (A-HSU®) technology to stun and cull smolt and juveniles immediately without chemicals. 

Juvenile fish are pumped or brailed into the entrance chute, where they flow directly into the water of the stun tube. The electric field in the stun tube ensures that the fish lose consciousness immediately. 

The water is pumped at a rate to transport the fish to the final dewatering grid, which takes about 40 seconds. The fish then fall into a harvest tub while an integrated water pump recirculates the water. Ice can be used in the harvest tub to preserve the fish.  

Key features

The A-HCS® is a self-contained, easily transportable unit. It’s designed to withstand robust biosecurity measures and protocols, reducing the risk of disease transmission.
