Growth of the Green Seaweed Enteromorpha prolifera under Different Seeding Methods

Abstract

Three methods ofEnteromorpha proliferaseeding, for commercial cultivation, were compared at the seaweed cultivation grounds in Yosino River, Tokusima Prefecture. The three methods were “natural”, “direct” and “artificial”. E. proliferafronds grew well on culture nets seeded by any of the methods applied; daily growth rates were between 20-40 %, with a maximum of 73.4 % during the test period. Plants only attained harvestable size when the nets were held at depths of 30-90 cm.
