Concrete panels and blocks containing arginine,one of amino acid (AC) had been setting on the sea in three different harbors. The results of the study are as follows; (1) the quantity of microalga on the AC was three times larger than ordinary concrete (OC), and they were fed by an feeder after ten months. (2) On the AC, green algae such as Ulva or Cladophora grew thick after microalgae extinguishment. We observed that these seaweed was not contamination sources but feed resources for other creatures. (3) It is known that thick growth of small-sized chlorophyceae inhibits of large-sized seaweed. On the other hand, Crustose Corallines, frequently seen in "ISOYAKE" area, did not appear on the AC. This result to suggests that the concrete containing arginine can be used as base material for large-sized seaweed adhering.
