The small size, high stability and high surface area of Fine Bubbles (FBs) give water unique features, which can be applied to enhance productivity in agro/aquaculture and water treatment fields. But in order to achieve maximum performance, FBs generated by appropriate methods must be used in appropriate ways. This project conducted two remote workshops with the aim to:

• harmonize the basic usage and measurements of FBs using ISO standards
• introduce various applications being developed in APEC economies
• share the practices on testing and evaluations being conducted in each application
• introduce the certification system of Fine Bubble Technology (FBT) in Japan as a method to guarantee the quality of FBs.

This report presents a summary of discussions from the said workshops.
