In response to the sustainability challenges in aquaculture, Aquanzo, an Edinburgh-based startup, is introducing a novel approach to aquafeed production with its Recirculating Aquaculture System (RAS).

Sustainable Solutions through Innovation

Aquanzo aims to support the growth of the aquaculture sector while minimizing environmental impact. Collaborating with CENSIS, Scotland’s innovation center, Aquanzo is developing a modular farm system fueled by agricultural and food by-products.

Artemia, essential for aquafeeds due to their high protein content, are traditionally harvested from natural salt lakes. Aquanzo, however, is cultivating artemia using nutrient-rich by-products from other industries, like malt waste from whisky production, ensuring sustainability and reducing carbon emissions.

Decoupling Aquaculture from Overfishing

By farming artemia instead of harvesting them, Aquanzo ensures greater control, scalability, and sustainability. This approach parallels successful models seen in insect farms but focuses on marine ingredients crucial for aquafeeds.

The Aquanzo RAS system minimizes impact on the marine ecosystem by utilizing recycled water and is projected to reduce CO2 emissions by 20% compared to traditional methods. Aquanzo’s commitment to sustainability extends to supporting aquaculture’s net-zero goals.

Harnessing Technology for Progress

Collaborating with CENSIS, Aquanzo integrates sensor technology for real-time monitoring of artemia welfare and growth. This ensures optimal conditions for cultivation, while the development of a fully mobile system will enhance efficiency regardless of location.
