(1) Migrating behavior of juvenile fishes in stream-type fishways This section is intended estimate upstream migration behavior for juvenile fishes in Denil, Steeppass, modified Larinier Pass and boulder-mounted slope fishways. Experimental facilities have used four kinds of fishways in the hydraulic laboratory and as juvenile fishes : ayu (plecogllossus altivelis), goby (chaenogobius urotaenia), char (Salmo (Oncorhynchus) masou marcostamus), trout (Salmo (Oncorhynchus) masou masou, Salmo (Oncorhynchus) masou marcostomus). As a result, juvenile ayu migrated the regions where generated weak turbulence, especially they went upstream along side walls in constant slope fishway. Also, as for the juvenile trout and char, they can select the routes according to their individual swimming potential, as cross sectional velocity distributions in boulder-mounted slope fishways are wide range. Moreover, it is necessary to provide the resting area for the bottom fish such as goby.(2) Microorganism b … More ehavior in eutrophic dams This section is intended to estimate the structural analysis of bacterial phase in river water and mud at Nagara estuary barrage and aerobic submerged biofilter in sewage plant at Gifu National College of Technology. The bacterial phase have a variety of quinones such as ubiquinone (UQ), menaquinone (MK) and prastoquinone (PQ). In the case of aerobic submerged biofilter in sewage plant, the bacterial phase of menaquinone (MK) dominated. Prastoquinone (PQ) according to photosynthesis action observed in river water and mud at Nagara estuary barrage. The water quality and organism index such as COD, chlorophyl-a, ignition loss and diameter of substance are proportional to quinone concentration in connection with bacterial amounts.(3) Creative enhancement of fish habitat In recent years, the importance of vegetation in rivers and dams in recognized not only then viewpoint of flow resistance but also from the ecological viewpoint as soft interface. Hydraulic action on vegetation, whether limited to banks and in-stream, controls, a major source of carbon to aquatic systems. Stream that are rich in carbon detritus provide an appropriate base for the aquatic food chain. To be effective detrital delivery from riparian zones should be designed at the "reach" scale or larger. Less

(1)幼鱼在溪流型鱼道中的迁徙行为本部分旨在估计Denil、Steeppass、Modify Larinier Pass和巨石坡面鱼道中幼鱼的上游迁徙行为。实验设施在水力学实验室中使用了四种鱼道作为幼鱼：Ayu(Plecogllossus Altivelis)、goby(Chaenogobius Urotaenia)、Char(Salmo(Oncorhynchus)Masou marcostaus)、鲑鱼(Salmo(Oncorhynchus)Masou Masou)、Salmo(Oncorhynchus)Masou marcostomus)。因此，幼鱼迁徙到产生弱湍流的区域，特别是沿恒坡鱼道的侧壁逆流而上。此外，由于巨石坡面鱼道的横断面流速分布范围较广，因此，对于幼鱼和赤鱼，它们可以根据各自的游泳潜力选择航道。此外，还需要为虾虎鱼等底层鱼类提供休息区。(2)微生物b…富营养化水坝的更多行为本节旨在估算岐抚国立理工学院纳加拉口拦河口和污水厂好氧潜流生物滤池的河水和泥沙中细菌相的结构分析。细菌相中含有多种对苯二酚，如泛醌(UQ)、菜籽酚(MK)和苯二酚(PQ)。在污水处理厂的好氧生物滤池中，细菌相以孟喹酮(MK)为主。根据在长城河口拦河口的河水和泥沙中观察到的光合作用作用，确定了对苯二酚的含量。水质和生物指标，如COD、叶绿素a、烧失量和物质直径与苯二酚浓度成正比，与细菌数量有关。(3)近年来鱼类栖息地的创造性改善，不仅从水流阻力的角度认识到河流和堤坝植被的重要性，而且从生态的角度认识到作为软界面的重要性。对植被的水力作用，无论是否限于河岸和溪流，都控制着水生系统的主要碳源。富含碳碎屑的溪流为水生食物链提供了适当的基础。要有效地从河岸地带输送碎屑，应设计成“可达”或更大的规模。较少
