Enteromorpha prolifera is an edible green alga and was Japanese name "aonori". The raw material is taken from naturally growing fronds in the brackish waters of estuaries in Japan. The fronds grow well during the winter (December to January) and spring season (April to May) in the Shimanto River, Shikoku, Southern Japan. The maximum length and standing crop of Enteromorpha fronds increased to more than 30 cm and 100 g/㎡ dry wt. respectively in the growing season. The horizontal distribution of Enteromorpha fronds grew well at shallower depth (T.P. -0.5 m to -1.5 m) in the winter season and at deeper layers (T.P. -1.5 m -3.0 m) in the spring season.
