Abstract
Fine bubbles of sizes less than 100 µm dia., are capable to efficiently increase dissolved oxygen level in the water or so when air is introduced into encapsulated gas in fine bubbles. For that reason, its remarkable availability is expected for agriculture and aquaculture.
However, it is required to properly coordinate properties of fine bubbles suitable for agriculture and aquaculture in order to obtain sufficient effects and availability. So far, fine bubble technology development has been continuously made in the current studies to take advantage of fine bubble properties based on actual usage of fine bubbles in such industries. As a result, it has revealed to be potentially effective, and needs to widely develop versatile usage of fine bubbles by identifying the system configuration and precautions of fine bubble usage in the agriculture and aquaculture.
