SAIC Introduces: POSH Technologies

In the latest 'SAIC Introduces' instalment, we're learning more about POSH Technologies...

Leveraging the POSH® Nanobubble Platform for Healthier Aquaculture 

POSH Technologies is developing a breakthrough platform that combines nanobubble science, electrochemical activation (ECA), and the proprietary POSH® delivery system to address the most pressing challenges in aquaculture: water quality, disease control, and fish welfare. 

Unlike conventional approaches, POSH’s platform does not just treat water—it provides a flexible delivery mechanism for oxygen, reactive oxygen species, and bioactive compounds directly where they are needed. This has multiple benefits for fish farmers and the wider industry: 

  • Enhanced water quality: Nanobubbles significantly improve oxygen transfer efficiency, helping maintain stable dissolved oxygen levels with lower energy costs. 
  • Pathogen control and biosecurity: On-site generation of safe disinfectants such as hypochlorous acid (HOCl) reduces reliance on antibiotics and bulk chemicals. 
  • Nutrient management: By targeting nitrates and phosphates, the technology mitigates harmful algal blooms and supports healthier aquatic ecosystems. 
  • Platform for innovation: The POSH® electrostatic delivery system can bind and carry positively charged molecules—such as immunostimulants, probiotics, or vaccine components—opening the door to next-generation fish health solutions. 

Early studies and pilot deployments suggest that POSH technologies can deliver measurable gains in growth rates, survival, and feed conversion efficiency, while reducing input costs and chemical risks. Importantly, the technology is scalable across hatcheries, recirculating aquaculture systems, and open-water pens, giving operators flexibility to apply it where it has the greatest impact. 

POSH is now seeking collaborations with research institutions, aquaculture producers, and fellow SAIC members to accelerate trials and validate new applications. By leveraging the POSH® platform, we aim to deliver healthier fish, lower environmental footprints, and more sustainable businesses for the aquaculture sector.
