WaterDoctor is proud to announce a landmark achievement in sustainable aquaculture: our deployment at Singapore Aquaculture Technologies (SAT) has achieved zero antibiotic use throughout its entire operational period. This milestone demonstrates that intensive, commercial-scale aquaculture can be both profitable and environmentally responsible. The SAT facility operates a 48m³ Recirculating Aquaculture System (RAS) for sea bass farming, paired with a 6m³ SND biological treatment system. Since deployment, the system has maintained consistently healthy water quality parameters, eliminating the conditions that typically drive antibiotic use in aquaculture. The fish have shown excellent health and growth rates without any pharmaceutical intervention. The results at SAT extend beyond antibiotic elimination. The facility has achieved a 50% reduction in operational costs, 50% energy savings compared to conventional RAS operations, and a 50% increase in stocking density. These improvements are enabled by our integrated approach combining SND biological treatment, AquaOS real-time monitoring, and AI-powered management optimization. This achievement is particularly significant given that the global aquaculture industry accounts for an estimated 80% of all antibiotics used in food production. By proving that zero-antibiotic farming is commercially viable at scale, WaterDoctor is helping to address one of the most pressing challenges in global food safety and antimicrobial resistance.
