Abstract
Decrease in fishery resources in the semi-closed sea, such as Seto Inland Sea, Ariake Bay and so on, has been a serious problem. The project started in 2006 for finding how to improve or preserve their environment for restoring fishery resources in the inland sea and how to keep or improve physical and chemical conditions closely related to fishery resources and ecosystem. Reviews or analysis for investigating material circulation through food chain or ecosystem in the Seto Inland Sea were done in this project.
 In this report, the current and nutrients transportation in the Seto Inland Sea as one of important elements that directly influence the biological production are discussed by reviewing the results of studies on the large semi-closed sea such as the Seto Inland Sea. The resolved problems and unresolved problems are made clear. The current and nutrients transportation in the Seto Inland Sea are also discussed from point of the process of biological production, environmental capacity, resource management and increasing fishery resources. According to the review, a hydrodynamic model coupled with primary production model was developed and applied to the Seto Inland Sea. The results calculated by this model show a good agreement on the hydraulic characteristics of the Seto Inland Sea. But primary production model included in this model should be improved by reevaluating its parameters and its structure.
