Abstract
The present state of the tidal zone environment along the coast of the Seto Inland Sea including Hiroshima Bay, Japan are reviewed. The potential and usage of technologies for tidal zone regeneration are discussed. Strategies for adaptive management for tidal zone regeneration are proposed; e.g., 1) unification project from wide area and local area of separated projects, 2) maintenance of necessary conditions for regeneration of the tidal zone, 3) unification of various geographic and biological information into a “Tidal Zone Fundamental Map”, 4) assessment of biological local net work for healthy regeneration, 5) development of cascading and various uses of purified sea water, 6) development of fisheries technology as part of fishing ground management from counter measures against harmful species to develop new resources.
