Eelgrass and seaweed beds are important places for ecosystem of coastal zone, and also fishing industry in Japan. Therefore, We have tried creating seaweed bed on the wave dissipating concrete blocks and the rubble mound of breakwater, at Togi fishing port in Isikawa prefecture. We were able to get four information about the design from monitoring the seaweed bed type breakwater. The first is the necessity of setting up the substratum of seaweed in accordance with maturity time of seaweed. The second is that of predicting the transportation range of its spores. The third is that of detailed investigation and development of measuring apparatus for the propagation of specific seaweed. The fourth is that of examining comprehensively the relation between seaweed bed succession and herbivorous benthos.
