Abstract
Red tide microalgae in the ocean, cause a various influence on human society as well as marine ecological system, and these influence tends to expand with global warming. It was subjected to systematic experiments on Heterosigma akashiwo using underwater shock wave that is driven by a propane-oxygen imploding detonation. As a result, by underwater shock waves treatment, we achieved 100% mortality rate Heteroshigma akashiwo. The mortality rate of Heterosigma akashiwo was found to be dependent on the maximum pressure of the underwater shock waves.
