Three-Sixty Aquaculture, UK’s sushi-grade shrimp experts, has started new technological trials with NanobOx and GIS Gas Infusion Systems Inc. These collaborations are key to furthering the company’s mission to drive innovation in Recirculating Aquaculture Systems (RAS).
The trial with NanobOx, a low-cost nanobubble water treatment company, will test the introduction of their breakthrough nanobubble generation technology into its RAS system. This technology significantly enhances oxygen transfer within RAS, improving shrimp growth rates and reducing feed conversion ratios (FCR), two critical factors for increasing efficiency and sustainability in land-based aquaculture.
NanobOx technology generates high concentrations of nanobubbles at just one one-hundredth of the power consumption of conventional nanobubble generation systems, offering RAS operators an unparalleled cost advantage. Beyond oxygenation, early research suggests the technology could also positively impact animal health and disease resistance.
Three-Sixty Aquaculture is also conducting CO₂ stripping trials using advanced technology developed by GIS Gas Infusion Systems Inc. The system, which uses proprietary 3D-printed hydrophobic discs, offers a highly efficient and compact alternative to traditional degassing towers.
By significantly reducing air and energy requirements, the technology is expected to lower operational costs while improving water quality. Early indications suggest that reduced CO₂ levels will contribute to enhanced shrimp health and improved feed conversion ratios, aligning with the company’s commitment to sustainable and high-performance RAS farming.
Speaking on the eve of his appearance on the Investment Panel at RAStech Conference in San Diego, co-founder of Three-Sixty Aquaculture, James Fox-Davies, said that “at Three-Sixty Aquaculture, we’re always looking for ways to enhance our technical processes and are excited to be embarking on these trials with NanobOx and GIS. Our adoption of nanobubble technology and CO₂ stripping at such low cost could mark a major advancement in producing high-quality, affordable seafood.”
The nanobubble and CO2 trials will run throughout 2025 and 2026, with initial results expected in Q3 2025. If successful, the technologies could have a wider impact beyond shrimp farming, improving oxygenation and productivity in higher-density species such as salmon.
Having developed its proprietary, patent-pending technology in its existing R&D facility in Swansea and raised £3.5 million in a Series A funding round, Three-Sixty Aquaculture is looking to invest the money to commercialize its shrimp farming at scale. Additionally, Three-Sixty Aquaculture has been granted three new innovative patents – four-cell tank design, continuous harvesting & grading system, waste & mort removal system – which set new benchmarks in aquaculture efficiency and sustainability, making prawn farming more viable.
