Sargassum thunbergii is an economically important brown alga. It has been utilized as preferred food for sea cucumber in China. The present study compared the mature S. thunbergii across multiple habitats in the northern Yellow Sea. Various materials (bamboo curtains, palmropes, vinylon ropes with epoxy resin, bricks, cement stools, and mesh belts) were applied as attachment substrata for the spores of S. thunbergii. Considering the simplicity of operation and density of sporelings, the bamboo curtains, palm ropes, and mesh belts were supposed to be more efficient attachment substrata for spore settlement. Techniques of sporeling rearing were developed for S. thunbergii and this paved the way for supplying sporelings for large scale cultivation.
