Leveraging the POSH® Nanobubble Platform for Resilient and Sustainable Aquaculture

POSH Technologies is developing an evidence-based platform that unites electrochemical activation (ECA) and nanobubble technology to improve water quality, fish health, and system efficiency across aquaculture.

The POSH® (Platform for Optimised Surface Hydrodynamics) system uses electro-catalytic processes to generate high-purity nanobubbles containing dissolved oxygen and reactive oxygen species. This enables precise, on-site control of water chemistry without the transport or storage of chemicals. The result is a flexible delivery mechanism that supports:

  • Enhanced oxygenation – improved gas transfer efficiency and feed conversion rates.
  • Pathogen and biofilm control – on-demand production of safe disinfectants such as hypochlorous acid (HOCl).
  • Nutrient management – Post RAS reduction of nitrates and phosphates and medications linked to harmful algal blooms.
  • Future therapeutic delivery – the charged nanobubbles provide a potential route for administering immunostimulants, probiotics, or vaccine components via water.

Laboratory and pilot studies indicate measurable gains in growth, survival, and welfare metrics while lowering energy and chemical inputs. The approach is fully scalable—from hatcheries and recirculating aquaculture systems to open-water pens—and aligns with ongoing research into microbiome stability and immune modulation.

POSH Technologies is now engaging with aquaculture producers, academic groups, and industry partners to design collaborative trials and explore tailored deployments. In addition to technology development, the team offers consulting and technical advisory services on integrating electrochemical and nanobubble processes within existing operations.

By leveraging the POSH® platform, the company aims to help the sector achieve cleaner water, healthier fish, and more sustainable production systems.
