Abstract

By turning attention to the wake area formed behind the blunt shaped object, where the diffusing dyestuff like minute particle pills up in fluid mechanically, we developed a technology to lead Sargassum's embryo to the wake area of 1mm granular substrate in diameter. We generated a steady flow in range of Reynolds number 3.6-75, by using the diameter of the granular substrate as a standing length, and dispersed the embryo. The embryo was lead to the back of the granular substrate, and clinging was comfirmed after 14 days of culturing. After 3 weeks of culturing from the day clinging was seen, the young plant'sattaching force exceeded than the fluid force which effect on the young plant in the ocean. We used ferrite particle as the granular substrate, and magnetized it. If it is scatterd to the algal reef made of steel, it is suggested that the transplanting technology of this style would be available even in the high waved ocean.
