Introduction of the "Terraced Fishway" case: Fishway design/construction on the Kanase River in Gifu Prefecture.
[Case Study] Improving upstream efficiency with a unique design! The terraced fishway solves the issues of conventional fishways.
In traditional 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 Fishway," which features a unique shape utilizing natural stones. We also provide explanations about the terraced 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: Prefectural Eco-River Kanse River and others ■Construction Location: Kanse River (Tachikubo Kiso-ya, Ibi-gun, Ibi-cho, Gifu Prefecture) ■Construction Photos: Please see the construction photos on this page. 【Points for Choosing the "Terraced Fishway"】 ■Fish can ascend from any direction due to the 180-degree design, preventing fish stagnation. ■It has a maintenance-free structure that prevents sediment accumulation inside the fishway. ■Thanks to its unique structure that can adapt to changes in water levels, it allows water to flow from the collection ditch below the floor during low water conditions. ■By realizing the concrete secondary productization as terraced fishway blocks, we have achieved stable quality and simplified construction for the fishway. *For more details, please contact us or download the catalog to view.
