Description

<p> The creation of seaweed beds is an important issue for the recovery of fishery resources and the maintenance of ecosystems, and has been attracting attention in recent years as it contributes to the promotion of blue carbon. In this study, we investigated the feasibility of using fermented wood powder mixed into mortar as a block for seaweed bed creation. First, the viability of yeast in the mortar was examined through laboratory tests. Then, the mortar specimens mixed with fermented wood powder were immersed in the sea for exposure tests, and the growth of algae was examined. The results of the laboratory tests showed that the yeast could survive for at least 13 weeks in the mortar by forming the fermented wood powder into clumps of about 25 mm in size. In the exposure tests, the mortar specimens containing fermented wood powder had significantly more laminaria japonica than those without fermented wood powder.</p>
