METHOD FOR RAISING SEAWEED AND CLOSED WATER SYSTEM USED FOR RAISING SEA WEED

摘要

PROBLEM TO BE SOLVED: To provide a method for raising seaweeds by feeding nutrition in a suitable amount required by the seaweeds for a long term while stabilizing water quality, and a closed water system used for raising the seaweeds. SOLUTION: The seaweed is grown by laying the seaweeds in a bottom body in the closed water system such as a water tank and transplanting the objective seaweed. The seaweed laid under the bottom is decomposed and fed to the objective seaweed as nutrients and an anaerobic environment and an aerobic environment similar to natural environment where the seaweed grows are made in the bottom by action of microorganisms.
