The green alga Enteromorpha prolifera (Mueller) J. Agardh is an important edible seaweed which grows in calm estuaries around western Japan. However, wild stocks of this species have recently decreased due to water pollution. Cultivated materials are now responsible for almost all of the processed Enteromorpha. Tokushima Prefecture forms the highest production area in Japan with an annual production of 60-70 tons (dry weight). However, there are some problems regarding the Enteromorpha cultivation in the Yoshino River estuary in Tokushima Prefecture and the biggest problem is the unstable natural seeding which depends on the swarmers discharged from wild plants. Therefore, the annual production of Enteromorpha in the Yoshino River has sometimes fluctuated due to the variability in natural seeding. This research has aimed at the establishment of the technology to stabilize Enteromorpha production.
