Ace Aquatec is teaming up with Lago Sofía, a leading smolt producer in Chile, to install its innovative A-HCS humane culling system.
Following a successful testing period, the chemical-free, in-water system is now fully operational at Lago Sofía’s Puerto Montt facility – its first use in Chile.

“Working with the team at Ace Aquatec has been a very positive experience for us,” said Alejandro Delgadillo, production manager at Lago Sofía.
“The A-HCS system has delivered results beyond our expectations, making the culling process safer, simpler and highly efficient. This technology has reinforced our commitment to animal welfare, while reducing costs and supporting our long-term sustainability goals.”
Lago Sofía, the first smolt producer in Chile certified under strict animal welfare standards, will use the A-HCS system during fish grading and vaccination stages.
The technology allows for the humane culling of juvenile salmon deemed unfit for sea transfer, replacing traditional anaesthetics with a chemical-free alternative, meaning these fish can now be used for human consumption and by-products.
The system has led to reported labour savings of up to 75%, reduced water consumption and a significant decrease in the use of chemicals and materials.
“Lago Sofía’s commitment to reducing chemical use and advancing toward a zero-waste supply chain sets an inspiring precedent,” said Constanza Fontaine, sales and service manager at Ace Aquatec. “This partnership demonstrates that advances in fish welfare, environmental responsibility and operational excellence can truly go hand in hand.”
