In order to avoid extinction of the kelp forest, Shizuoka Prefecture implemented a ‘Fisheries Infrastructure Development Project’ by deploying blocks implanted with E. cava thalli on the barren bottom formerly inhabited by the kelps. Furthermore, we also implemented another project to establish new methods of transplantation to cope with browsing by herbivorous fishes. In the project, restoration of E. cava forest was tried using ropes implanted with E. cava juveniles and removal of herbivorous fish by fixed net and gill net. The shoreline survey conducted in February 2008 revealed that 55 ha of E. cava forest was restored along the coast.
