Numerical experiment of the method for creating fishery ground in and around the Bisan-Seto

Abstract

The Bisan-Seto is located to part of Seto-Inland sea, Japan. There are many spawning grounds of valuable marine resources. It has been decreased aquaculture habitats in and around Bisan-Seto area. In the field experiments, we measured water quality, tidal current velocity and biological condition including marine resources eggs and larvae in and around that area. We are researching physical and biological effects of planned artificial reef as diving it has been confirmed are becoming good biological environments including prey abundance for marine resources.
