| Outline of Final Research Achievements |
The aim of this project is to develop a system for eradicating copepods that become harmful organisms for the larvae and juveniles of culturing marine invertebrates using swirl flow type and de Laval nozzle type micro/nano bubble generator. In the killing experiments, both devices could physically kill copepods. In addition, at a center for stock enhancement, we installed de Laval nozzle system in a pipe line providing sea water to culturing aquariums, then cultured juveniles of sea cucumbers using the system treated water. As a result, the damage of copepods was suppressed and seeds of sea cucumber survived until becoming the shipping size.
