In this study, it was intended that we evaluated stability of the stratification for an index quantitatively about the current control function by the artificial reef in a fishery ground constructed in Osaka bay. After field research, we calculated Ri (Richardson number) which was the index of the stability of the stratification, ME (mixed effect), UE (upwelling effect) and compared those values in a fishery ground with control area that set for the downstream side. As the results of investigation of Ri in the fishery ground was smaller than control area and UE>0. It was confirmed upwelling and mixture of lower water mass in the constructed fishery ground.
It was concluded that mixture of the seawater, upwelling occurred by located artificial reefs, and the knowledge for quantitative evaluations of the current control function were successfully obtained by field research.
