The new method of plantation of Eisenia arborea Areschoug was tried on the rocky shore for the forest regeneration at the mouth of Ise Bay. In December 2004, the sol of the sporophyte (average sporophyte length : 0.46mm, consistency : 5.9×10^3 inds./wet・g)was mixed with the 3% (w/w seawater) sodium alginate and 20% (w/w sodium alginate sol) sand. The sol with the sporophyte was applied to the concrete surface (approximately 0.6m^2) of the artificial reef for abalone located on Toyohama coast in Aichi Prefecture. The sol was fixed on the surface by using the 'Corking gun', an architectural tool, by scuba divers. In April 2005, the fronds have grown on artificial reef. Their length increased from 10cm to 20cm, and their population was estimated at 107inds. This method will reduce labor and cost for seed cultivation, and requires no material to anchor fronds on the seabed.
