| Research Abstract |
The purpose of this study is to restore seaweed beds in the east part of Muroto coastal area, where is a typical sea desert area so-called "Isoyake". The results of field survey, in-situ and laboratory experiments, and numerical simulations showed that seaweed beds in the research field are declined year by year, seaweed growth rates increase with increasing deep ocean water concentration except from very low temperature condition, herbivorous fish escapes from a low temperature water mass, and installation of an accumulation structure may effectively keep a water mass of high deep ocean water concentration.
