Recovery from the Isoyake of Ecklonia cava Beds

Abstract

I introduced two cases(the recovery as natural phenomena and the recovery by human work) about the recovery of Ecklonia cava beds from the Isoyake in Shizuoka Prefecture. In the recovery from the Isoyake as natural phenomena, it has been understood that the generation group that survived in year when a certain condition was satisfactory grew up and formed Ecklonia cava beds. In the recovery case by human work, after the situation of the Isoyake had been diagnosed by the implantation test, the alga place creation that combined a large-scale transplant and the capture of herbivorous fishes Siganus fuscescens was done. As a result, the Ecklonia cava beds was made to exist in the Isoyake area, and the next generation came to appear.
