Introduction of the "Terraced Fishway" case: Fishway design/construction on the Neo River in Gifu Prefecture.
[Case Study] Improving upstream efficiency with a unique design! The terraced fishway solves the issues of traditional fishways.
In conventional fishways, there were challenges such as difficulty in guiding fish to upstream routes and sediment accumulation within the fishway, which reduces its functionality. These issues are addressed by Yamatazumi's "Terraced Rice Field Fishway," which features a unique shape utilizing natural stones. We also provide explanations about the terraced rice field fishway, consultations on fishway design (such as drawing creation and quantity calculation), proposals, and assistance, so please feel free to contact us. 【Case Study】 ■ Project Name: Neogawa No. 4 Bed Stabilization Improvement Project ■ Location: Neogawa (Ishigami, Motosu City, Gifu Prefecture) ■ Construction Photos: Please see the construction photos on this page. 【Points for Choosing the "Terraced Rice Field Fishway"】 ■ Fish can ascend from any direction due to the 180-degree design, preventing fish from stagnating. ■ It features a maintenance-free structure that prevents sediment accumulation inside the fishway. ■ Its unique structure can accommodate changes in water levels, allowing water to flow from the collection ditch directly beneath the bed stabilization during low water periods. ■ By realizing the concrete secondary productization as terraced rice field fishway blocks, we have achieved stable quality and simplified construction for fishways. *For more details, please contact us or download the catalog to view.
