A new type of seaweed reef has been developed in Hokkaido, Japan, which uses natural stones and is very effective for the culture of kelp, etc. Previously, reefs were caused by large boulders or blasting in water, Due to environmental pollution caused by a large number of biological phenomena along the coast of rock and sea creatures.
