Part 3: Recirculating Aquaculture Systems — Aquaculture´s Path to Sustainability?
Tasked with feeding the growing global population, the aquaculture industry is facing severe sustainability and scaling challenges. One of the technologies helping to bridge the gap between global protein demand and seafood production is Recirculating Aquaculture Systems (RAS). RAS are closed-loop systems where fish or other marine species are raised in tanks. Water is filtered to remove gases and solid waste, purified, and recirculated — efficient systems can re-use more than 95% of water. End-to-end RAS innovators (e.g., The Kingfish Company) combine proprietary system’s design, software, and in some cases genetics or feed specifically developed for RAS, while others develop personalized turnkey RAS systems (e.g., Nofitech, Billund Aquaculture) or SaaS (e.g., Singapore Aquaculture Technologies) for the design and management of new RAS farms.
