We report a concept for “Seaweed Bed and Tidal Flat Vision” of Fukuoka prefecture. Fukuoka
prefecture is formulating the concept in response to a new “long-term plan for development of fishing
ports and fishing grounds” created by the Japanese government. Because three water areas in our
prefecture, the Chikuzen Sea, the Ariake Sea, and the Buzen Sea have own characteristics, the visions for
each water areas are under consideration.
We introduce the visions for the Chikuzen Sea and the Ariake Sea in this paper. In the Chikuzen Sea
facing open water area, the substrates such as rocks and concrete blocks are installed for creation of
seaweed beds. In addition, we perform transplantation of mature seaweeds and eradication of algae-eating
pests. On the other side, tidal flat is well developed in the Ariake Sea. We install various substrates to
improve sea beds environments for creation of rich sandy ecosystem. We also set about preparing
conservation and management of clam stocks in the Ariake Sea.
In addition to hardware elements for development of a new fishing grounds, we need software
elements such as management of fishing grounds using monitoring by local government, activities for the
conservation and the management by fishers. It is important of the conservation and the creation of
seaweed beds and tidal flat that combine the software elements and the hardware elements.
