Nano-Bubble applications in aquaculture industry for improving harvest yield, wastewater treatment, and disease control

A groundbreaking study has highlighted the potential of nanobubble (NB) technology to revolutionize the aquaculture industry by improving harvest yield, wastewater treatment, and disease control.

According to research led by Sudheera Yaparatne and colleagues, NBs—gas-filled pockets smaller than 1 micrometer—offer distinct advantages over traditional macro and microbubbles. These include prolonged water residence time, superior gas transfer efficiency, and hydroxyl radical production, making them a promising tool for sustainable aquaculture practices.

The study reviewed a decade’s worth of research on NB applications, focusing on three primary areas: increasing aquaculture productivity, controlling harmful microorganisms, and reducing oxidative stress to enhance animal health. Findings indicate that air and oxygen NBs significantly boost fish and shrimp growth rates, total harvest, and survival while reducing oxygen consumption. Additionally, ozone and air NBs have demonstrated effective pollutant degradation and pathogen control, leading to healthier aquatic environments.

Despite these promising results, the study highlights gaps in comparative analyses between NB and conventional treatments. Researchers call for further investigation into health and safety implications, economic feasibility, and infrastructure changes before widespread industry adoption.

As interest in sustainable aquaculture solutions grows, experts emphasize the need for continued research to validate the long-term benefits of NB technology. Industry stakeholders are encouraged to explore this innovative approach for enhanced efficiency and environmental responsibility.
