| Outline of Final Research Achievements |
The aim of this study is to develop the spatial biomass prediction model of fish and benthic invertebrate in the water system of Saba River. Field surveys were conducted to understand the relation between hydraulic characteristics and biomass of fish and benthic invertebrate, and we established GLM to predict the biomass using the hydraulic characteristics. The change amount of biomass of benthic invertebrate in mainstream of Saba River is predicted by using GLM and calculated hydraulic characteristics by fluid models. The result revealed that the total biomass of fish and benthic invertebrate was reduced by the negative impact of water intake.
